Description

The utility model relates to electrical engineering, and more specifically, to devices for maintaining the working state of secondary elements (batteries), and can be used in power systems of various technical devices and systems (TUS) for charging integrated batteries (batteries) integrated into them, mainly for providing wireless induction charging of batteries of mobile / portable electronic devices / devices, especially those with high demands on the reliability of operation and simplicity / convenience of enhenia.

To meet the needs of modern society, mobile / portable electronic devices / devices (PEPs) such as wearable radio stations, mobile phones, medical devices, various sensors of monitoring / data collection systems, etc. are widely used. As a rule, PEPs operate autonomously with power supply from built-in These are batteries, the recovery of which is carried out using chargers (chargers). At the same time, the most common practice is to use the simplest chargers that are connected to the probe using a wire / contact method (using connectors and cables) for charging a battery integrated into the probes. The practical use of such a power supply system of an electronic device (SEEP) has low efficiency in terms of ensuring high reliability of operation and simplicity / usability of the probe. This is due to the action of factors of an objective and subjective nature, which can cause SEEP failures, leading to a loss of performance of both the battery and the probe. The low efficiency of the SEEP is due to the low reliability of the elements of the wire interface (EPI), through which the charger is connected to the probe. It is the EPI that are implemented on the basis of wires and connectors that are subject to intense wear, as they are very vulnerable to external influences. Typical factors that reduce the reliability of EPI are environmental factors such as dust and moisture, which cause pollution / oxidation / corrosion of EPI elements, and mechanical loads of a different nature, due to the action of which ruptures can occur in cable / wire conductors and deformation / structural failure connectors included in the EPI. As a result of exposure to EPI environmental factors, including incorrect actions of individuals / users of PEP and memory (for example, careless handling of PEP, memory and EPI), the reliability of EPMS can be significantly reduced. It should also be noted that as a result of contamination / oxidation / corrosion that occurs on EPI, a significant increase in the resistance of the electrical circuit through which the battery is charged can also occur. As you know, typical EPI malfunctions are a decrease in the quality of contacts or the occurrence of a gap in the electric charging circuit, which causes, accordingly, a significant increase in the duration or complete cessation of battery charging. For these reasons, malfunctions in the SEEP can occur, leading to a partial or complete loss of performance of both the battery itself and the probe as a whole.

As you know, many of the probes are used in critical areas of activity of people, for example, in emergency services, units of law enforcement agencies (police, state armed forces, etc.), where the probes are subject to increased requirements for reliability and efficiency of use in difficult conditions and stressful (for PEP users) situations (SUSS). It is obvious that when using the “PEP + memory” system in the SSS, the reliability of such a SEEP, in which the memory is used with a wire / contact EPI, is significantly reduced due to the action of the mentioned environmental factors, including subjective factors.

In the process of research, it was found that SEEP known from the technology have low reliability and are not convenient for use to restore the battery to provide power to the probe, which significantly affects the efficiency of the probe, especially when they are used in difficult conditions and / or under stress (for user PEP) situations, therefore, the search for new, more advanced technical solutions in this area is an urgent task.

Studies have shown that the solution of the problem associated with improving the efficiency of operation of the probe, including in the SSS, is difficult due to the following contradiction. So, on the one hand, in order to charge the battery built into the probe and ensure its autonomous functioning, the “ZU + EPI” system must be used. On the other hand, the use of a system of the type “ZU + EPI” significantly reduces the effectiveness of the application of PES, especially in the SSS, which is due to the low reliability of the SEEP, since the EPI are vulnerable to the action of the mentioned external environmental factors, therefore the system “ZU + EPI” is to be used not necessary. It is obvious that without the use of the “ZU + EPI” system, the restoration of the battery’s performance, which ensures the autonomous functioning of the probe, becomes impossible.

Studies have shown that the power supply to the probes can be presented in the form of a model containing the following links: "Battery - Interface - Charger", where the battery is a rechargeable battery that provides autonomous operation of the probe, the charger is the charger used to service / charge the battery, Interface - the method and means used to connect / connect the charger to the probe when charging the built-in battery. The analysis of the proposed SEEP model showed that the most “weak / key link”, from the point of view of ensuring reliability and simplicity / ease of use of the probe, is the “interface” link, so the authors of the study focused on the search for technical a solution that allows you to "strengthen" (increase the reliability and ease of use) of this particular link. It is assumed that increasing the reliability of the “key link” will increase the efficiency of both SEEP and PEP as a whole.

An information / patent search found that known devices / systems / technical solutions that operate using autonomous power systems that correspond to the proposed model of the type "Battery - Interface - Storage" have significant drawbacks that reduce the effectiveness (reliability and convenience / simplicity) of their use , especially in the CSS.

So, from the technology [L1] the power supply system of a mobile phone (hereinafter referred to as the system) is known, consisting of a mobile phone (MT) containing an indicator, a rechargeable battery (battery), a port for connecting external devices (ППВУ) and a charge controller (KZ), which its first, second and third ports are connected, respectively, with the battery assembly, with an indicator and with the first port of the PPVU node, which is made in the form of a connector mounted on the MT case, and providing the possibility of mechanical and electrical connection of external devices to the MT, and chargeable (as necessary, charge the battery assembly) with it by a wire / contact method of a charging device (charger) containing a wired interface (PI) in series, a voltage / current stabilizer (SNT), a power supply unit (PSU) and a network cable (SK). At the same time, the system is made with the possibility of wired / contact connection of the memory unit to the MT node to carry out the charging procedure of the battery node. In addition, the PI node is made in the form of a cable with a plug with the ability to connect to the second port of the PPVU node, the memory node is made in the form of a network adapter that provides the formation and supply to the MT node of the voltage necessary to charge the battery node.

The device operates as follows. The MT node receives power from the battery. To charge the battery node, the memory node is used, which, as necessary (for charging the battery node) is connected to the MT node. The memory unit is a typical network adapter / charger, which is connected to the MT using a wired / contact connection using the PPVU and PI nodes. At the same time, the PPVU and PI nodes are made, respectively, in the form of a multi-pin connector mounted on the body of the MT unit, and in the form of a cable with a plug. The PPVU and PI nodes are made with the possibility of mechanical articulation and electrical connection of circuits providing switching / supply from the memory node to the MT node of the voltage necessary to charge the battery assembly. In the initial state, the degree of charge of the battery assembly is displayed using the indicator. For example, after a battery is discharged, the color of the indicator light changes from green to red. In this case, it becomes necessary to charge the battery assembly. To do this, the user of the system connects (mechanically and electrically connects) the PI and PPVU nodes and connects the SK node to a power outlet (220 V, 50 Hz). The voltage from the output of the charger unit is supplied through the PI and PPVU nodes to the battery node and, under the control of the short circuit node, the battery node is charged. The charge mode of the battery node is determined by the algorithms installed in the short circuit node. For example, if the unit consists of lithium-polymer batteries, then their charge is carried out by a standard method known from [L2]. After the battery node is charged, the color of the indicator light changes from red to green. After that, the operator / user of the system can disconnect the memory node from the MT node by physically disconnecting the PI node from the PPVU node.

This system has low reliability and is not convenient to use, due to the following reasons. So, the use of nodes ППВУ and ПИ, which are made in the form of standard connectors, providing switching of electric circuits used to charge the battery assembly, significantly reduces the reliability of the system and its ease of use. This, in turn, is due to the fact that any mechanical joint used to connect / commute electrical circuits is subject to wear / damage, including due to the action of friction / abrasion processes that occur during mechanical jointing of connectors, their corrosion, and also due to the careless handling of these nodes (ППВУ and ПИ) by its users / individuals during the operation of the system (when performing battery charging procedures). Also, PPVU and PI nodes are vulnerable to mechanical stresses (vibrations, shock, excessive pressure, kinks / distortions, stretching, etc.) and to the effects of various environmental factors (increased humidity, dust, etc.), as a result whose actions accelerate the processes of wear and failure of the PPVU and PI nodes, which serves as a source of unforeseen / premature failures in both SEEP and PEP, especially in the SSS.

The power system of a portable radio station (hereinafter referred to as the system), consisting of a radio station (PC) containing a storage battery (battery), an indicator, an external device connection port (ППВУ) and a charge controller (KZ), which is own from the first through the third ports it is connected, respectively, with the battery assembly, with the indicator assembly and with the PPVU assembly, and connected to it via the wire / contact connection of the charging device (charger), which contains the wire interface (PI) connected in series, a voltage / current stabilizer (SNT) , from tevoy power supply unit (PSU) and the power cable (SK). At the same time, the memory node is made in the form of a network adapter, which provides the formation and supply to the PI node of the voltage necessary to charge the battery node, the PI node is made in the form of a cable with a plug, which allows the memory to be connected to the second port of the ППВУ node for the battery node charging procedure .

The functioning of this system is carried out similarly to the previous device. Differences can only be in the used battery charge algorithm, implemented by the short circuit node.

This system partially eliminates the disadvantages of the previous system, which is achieved due to the fact that the PC node is designed and manufactured for operation in difficult conditions. The PC case is made using durable / wear-resistant structural elements (cast aluminum chassis) and is splash-proof. External connectors, including the PPVU assembly, are sealed with rubber seals and reinforced with bolted joints. This provides increased stability of PPVU and PI nodes to the effects of external environmental factors, including mechanical loads, dust and moisture. Therefore, the “interface” link of this system has higher reliability.

This system has disadvantages similar to the previous system. This is due to the fact that the “interface” link is organized using structural elements (connectors, cables), which have low reliability, as they are vulnerable to environmental factors. Units PPVU and PI, especially in SUSS, are subject to intense wear and tear, destruction under the influence of mechanical loads, dust, moisture and other environmental factors. The presence of wire connections established during the implementation of the procedures for charging the battery assembly is very inconvenient in use, especially in the SSS.

In the process of research, it was considered the possibility of increasing the efficiency of the mentioned “interface” link due to its implementation on the basis of wireless power transmission technology (BPE) for use in order to charge the battery built into the probe. This idea is based on the fact that the exclusion from the “interface” of bulky and inconvenient to use elements (PPVU and PI nodes) that are influenced by environmental factors (intense wear and tear, destruction by mechanical stress, dust, moisture, etc.), and also complicating the maintenance / charging of the battery assembly, it can significantly increase the efficiency of both SEEP and PEP, especially in SUSS.

The BEP methods are known from the technology [L4, L5], among which the most widely used / used in portable power systems that restore battery life of portable devices was wireless induction charging (BIZ) based on the use of electromagnetic induction. For the implementation of BEP inductively used inductively coupled coils located in the transmitting and receiving circuits. BEP is carried out by creating an alternating current in the transmitting coil, which forms in the local space in which the receiving coil should be placed an electromagnetic field (EPM). Under the action of an EPM, a voltage is created in the receiving circuit, which can be used to charge the battery built into the probe. It is noted that the BEP technology used for induction charging of batteries of portable / mobile devices / devices / systems has several advantages, including ease of use, since users of the probes to perform battery charging simply put this probes on the case / charging platform of the charger, universality, since users can charge any model of probes from a standard wireless charger, practicality, since the IZU allows you to simultaneously charge multiple probes, as well as high due to the fact that during battery maintenance there are no wired connections between the charger and the probe and its design can be made with sufficient reliability (for example, more reliably sealed) and adapted for use in the SSS.

A standard for wireless induction energy transfer Qi is known from the technology [L6], which regulates the operation of a transmitter located on a charging platform (ZP) and a receiver compatible with it, which can be integrated into the probe to charge the built-in battery. According to the Qi standard, an electromagnetic induction between two flat coils is used for the BEP. One of them is integrated into the charging platform (ZP) and connected to the energy source, and the second is the receiving one and is installed inside the probe to charge the built-in battery.

According to the authors, the implementation of the “interface” link in the proposed SEEP model based on Qi-type WPT technology is very attractive and deserves a more detailed study, since it becomes possible to exclude elements with low reliability that are subject to intensive wear in the “interface” link of the SEEP model destruction under the influence of mechanical loads, dust, moisture and other environmental factors and, thereby, provide a solution to the problem associated with improving the reliability of the power supply system PEP, as well as simplicity / convenience of its use, especially in difficult conditions / stressful situations. At the same time, the absence of connectors in the case of the probe, through which power is supplied from the external charger, allows more reliable protection of the battery and probe assembly from external factors such as dust and moisture, and the possibility of charging the battery built into the probe without using wires / cables and connectors greatly simplifies the process of tinning the battery used to power the probe.

From the technology [L7], a wireless power transmission device (hereinafter referred to as a device) is known, consisting of a charging platform (ZP) containing a controller, indicator, electronic device presence sensor (DTEC), a transmitting coil (PC) and a contact surface (KP), which it is structurally (physically) connected to a PC node, which is connected by its port to the first port of the controller node, which is connected with its second and third ports, respectively, to the indicator input and the output of the DPEP node, while the PC node is integrated (on the physical level f) to the KP assembly, as part of the resonant circuit, and is configured to generate a complex alternating magnetic field in the local area, covering the dimensions of the KP assembly, and connected to it via wireless (inductive) communication of an electronic device (EP) containing a battery connected in series (Battery) and a receiver of electromagnetic energy (PEE), configured to receive electromagnetic energy from the RF node and use it to charge the battery node.

This device operates as follows. After connecting the RF to a power source, for example, a 220 V power supply network, the controller starts processing signals from the DPEC node. When an EF is installed on the contact surface of the RF, its presence is fixed by the DPEC node and this node sends a signal to the controller, after which the controller activates the WPT process. The PC node is integrated into the contact surface, as part of the resonant circuit, and provides the generation of a complex variable magnetic field, which goes to the PEE node, where it is converted and used to charge the battery, which provides electric power to the electric field. The presence of the WPT process is displayed using the indicator light. When the WPT is completed, the indicator turns off. The contact surface, designed to accommodate the EP housing on it, contains an element of the type of protrusions / recesses used to position the EP on the RF, which is necessary for the implementation of WPT with sufficient efficiency.

This technical solution (TP) provides for the implementation of wireless transmission of electrical energy, which can be used to charge the battery of an electronic device. This TR is focused on the implementation of wireless induction charging of batteries of portable electronic equipment, which must be installed for this purpose on the contact surface and contain the necessary receiving circuits providing the WPT process. At the same time, the battery charging procedure can be organized in accordance with standard algorithms. The advantages of this TR include the fact that it allows you to charge the battery without the use of structural elements such as PPVU and PP nodes (made in the previous system using connectors and cable), which are subject to intense wear, destruction under the influence of mechanical loads, dust, moisture and other environmental factors. The ability to wirelessly charge the battery pack (without using a wired / contact connection between the PC and the PC) can significantly improve the reliability and usability of this type of power system. Also, the advantages of this TR should include automatic activation of the transmitting part, the operation of which is switched on by a sensor for detecting the presence of EP on the gearbox, as well as the ability to position and fix the EP on the gearbox node using protrusions / recesses in the contact surface, which ensures the creation of optimal WPT conditions.

The disadvantage of this TR is its low efficiency, in terms of the reliability of control and management of WPT processes and battery charging modes, as well as the lack of signs and properties that make it possible to restore a BIZ of a battery node without the participation of individuals. For example, with a slight violation of the positioning of the KP and PEE nodes under the influence of external physical influences or with violations in the positioning of the nodes, when the transmitting and receiving coils are removed from each other, the WPT efficiency (efficiency) can significantly decrease. At the same time, in this TR, compensation for the impact of these influences with the possibility of automatically, without the participation of individuals, achieving the necessary level of WPT efficiency to support the specified battery charging mode and / or notifying individuals about the occurrence of emergency situations is not provided. Also in this TR there is no channel for controlling the WPT process, depending on the state of the battery assembly. In practice, this means that the BEP and the charging of the assembly can continue as long as the ES assembly is installed on the contact surface of the RF, which can cause a recharge of the battery assembly and impair its operability.

From technology [L8], a known system of inductive charging of a battery (hereinafter referred to as the system) consisting of a primary circuit (PC) including a power source (MI), a primary coil (PC), a feedback detector (DOS) and a primary circuit controller ( KPC), which is connected with its first and second ports, respectively, to the first port of the MI node and to the first port of the DOS node, which is connected by the second port to the first port of the PC node, which is connected by the second port to the second port of the MI node, and the associated wireless way (through inductive coupling - AND ), a secondary circuit (CC), including a secondary coil (VK), a feedback circuit (DSP), a battery (battery) and a charge controller (KZ), which is connected, respectively, with its first, second and third ports to the node Battery with the first port of the VC node and the first port of the DSP node, which is connected to the second port of the VC node by the second port. At the same time, the DSP node is configured to generate and transmit a feedback signal to the primary circuit through inductive coupling between the PC and the VC, the KPC node is configured to control the power level supplied from the IM node to the PC node, in accordance with the level of signals received from the node DSP through the feedback circuit through inductive coupling between the PC and VK nodes, the KZ node is configured to implement the necessary algorithm for charging the battery node, detecting overvoltage / excess current modes in the battery charge circuit and generating a signal the control unit DSP used for controlling the wireless power transmission process (increase or decrease transmit power of electricity).

The system operates as follows. To perform the charging procedure for the battery node, the PC node is first connected to the supply network (220 V). In the simplest case, the PC node can be implemented as a typical network unit / power adapter. An alternating voltage is supplied from the IM node to the PC node, the radiation power of which is controlled by the KPTs node. Since the primary and secondary coils of the system are inductively interconnected, an input voltage is generated in the secondary circuit due to electromagnetic induction, which is used to charge the battery assembly. At the same time, the short-circuit node monitors the overvoltage or excess current created on the battery node in the process of its charge. The detection of these states is carried out using a short circuit node that implements the functions of an overvoltage detector and an excess current sensor. To eliminate the effect of “stressful states” (overvoltage and overcharging) on the battery node, the control unit sends a control signal to the DSP node through which the DSP node sends a feedback signal through the VC and PC nodes, which is detected by the DOS node. The output signals of the DOS node are sent to the KPC node, where their level is estimated. After that, the control unit of the IM node is formed by the KPC node, which leads to a change in the power level emitted by the PC node. Thus, in the process of performing the charge procedure for the battery assembly, the KPC and DSP nodes, a feedback signal is generated, which is transmitted to the secondary circuit by means of inductive coupling established between the VK and PC nodes. This allows you to control the amount of transmitted energy used to charge the battery assembly. It should be noted that the PC node is made as part of the oscillatory circuit and the power level emitted by the PC is controlled by changing the frequency of the signal supplied to the PC. So, to increase the voltage generated in the secondary circuit, the level of signals transmitted through the feedback circuit is increased, which causes a shift in the frequency of the signal supplied to the primary coil, closer to the resonant frequency of the oscillating circuit (of which the PC unit is a part). To reduce the radiation power of the PC node, the frequency of the signals supplied to the primary coil is shifted away from the resonant frequency of the oscillatory circuit (of which the PC node is a part). Thus, the signals received through the feedback circuit are used to control the power of the electromagnetic field emitted by the PC. As the battery node charge is completed, the signals in the feedback circuit are formed in such a way that the frequency of the signal supplied to the PC is diverted farther and farther from the resonance until the feedback signal ceases to be received, which practically leads to a shutdown the process of wireless transmission of electrical energy (input voltage at the CC tends to zero).

This technical solution (TR) partially eliminates the drawbacks of the previous TR, which is ensured by more efficient control of the WPT process and battery charging, which is achieved through the use of a feedback circuit that provides greater flexibility in the response of the system to both the state of the WPT channel and the state / battery charging mode.

This system has disadvantages similar to the previous TP. In addition, the “interface” link, which provides wireless power transmission during charging of the battery assembly, may function unstably / with failures resulting from environmental factors, for example, violations of the exact mutual positioning of the PC and VK nodes, contamination of the cases of the PC / nodes VC, causing weakening of the WPT process, the impact on the process of wireless power transmission of foreign objects, which can cause the formation of interference in the feedback circuit and disrupt node press charge the battery. Also, the system is vulnerable to factors of a subjective nature, for example, due to actions (negligence in use) of system users that may violate the required recommendations for system maintenance, including the mutual placement of the PC and CC nodes. Violations in the positioning of PC and VK nodes can create emergency situations (AS), that is, such states of the system in which the WPT efficiency is significantly reduced and the charging mode of the battery node is violated (battery charging time increases or stops). In this system, the possibility of fixing / automatic elimination of speakers, as well as notifying individuals about the occurrence of speakers, is not provided. Since violations of the mutual placement of the PC and AC nodes, which significantly affect the efficiency of the WPT, the system hardware cannot be eliminated and individuals cannot be notified in a timely manner about the occurrence of AS, this leads to the fact that the battery’s maintenance / charging time is built into PEP can increase significantly.

An information / patent search found that the devices / systems / technical solutions known from the technology that can be used for wireless induction charging of the batteries built into the probes have significant drawbacks that reduce the reliability and efficiency of the probes, especially when used in the SSS. Studies have shown that the main reasons that significantly affect the performance and convenience of the practical use of devices with an integrated in-built battery are the criticality to the conditions for the mutual placement / positioning of the charging platform and the probe. So, according to [L8], BEP systems are very critical to the distance between the coils (PC and VK) and the accuracy of their positioning relative to each other. The more accurately the receiver coil enters the transmitter field, the stronger the charging current will be, which means less time will be spent on charging the battery. When using the BIZ to perform the battery charging procedure (battery assembly), the user must strictly follow the instructions on the relative position of the charging platform and the probe, since the accuracy of their positioning significantly affects the charging efficiency, which is expressed in an increase in its duration. It was experimentally established that a deviation of the relative position of the transmitting and receiving coils (PC and VK nodes) by about 15% causes a decrease in the WPT efficiency and a violation of the battery charge mode, which is expressed in an increase in the duration of the full charge of the mobile phone’s battery for a time of about 50 minutes. It is also noted in [L9] that for the most efficient energy transfer it is necessary to ensure the best interaction between the receiver coil and the magnetic field created by the coil - the energy transmitter. In this case, the optimum distance between the transmitter and receiver depends on the diameter of the coil. To ensure optimal FET conditions, the transmitter and receiver coils having radial sizes of about 30-80 mm, according to the requirements of the Qi inductive charging standard known from [L10]), should be located at a distance of no more than 3-8 mm. That is, the cases of the charging platform and the probes should be located practically closely so that both coils (PC and VK nodes) are positioned (in horizontal and vertical planes) next to / opposite each other. It is noted that with an increase in the distance or a violation of positioning between the PC and VK nodes by an amount exceeding the permissible value (about 3-8 mm), the WPT process efficiency decreases catastrophically - from 70% to several percent.

According to the authors, the elimination of the shortcomings inherent in devices and systems of wireless charging known from the technology can be based on such a technical solution, which provides the possibility of continuous monitoring of the efficiency of WPT processes and the charge mode of the battery node with alarm signaling (AC) associated with violations of WPT and battery charge (for example, caused by the displacement of the probe from the charging platform), to attract the attention of the PL in order to timely / take measures to ensure conditions for an effective WPT and support for OF DATA battery charge modes. In addition, since even insignificant (several millimeters) displacements of the PC and VK nodes in any of the planes of space entail a decrease in the efficiency of the WPT processes and the charge mode of the battery node, which is difficult for an individual to visually notice, the use of new features and properties that provide automatic calibration / adjustment positioning of PC and VK nodes with high accuracy can provide a significant increase in the efficiency of SEEP using induction battery charging, which is built into the probe.

According to the authors, the closest in technical essence to the claimed object (prototype) is, known from the technique [L11], a device for induction charging of a portable device’s rechargeable battery (hereinafter referred to as the device), consisting of a charging platform (ZP) containing a case, an electric power supply unit (BEP), a current / voltage converter (ПТН) type AC-DC, a primary coil (PC), a current / voltage sensor (ДТН) and a charging platform controller (KZP), which is connected with its first and second ports, respectively, to the first port node PTN and with lane the output port of the DTN node, which is connected by its second port to the first port of the PC node, which is connected by the second port to the second port of the ПТН node, which is connected by the third port to the second port of the BEP node, which is configured to connect its first port to the 220 V power supply network, this, the housing of the RF node is made with a built-in permanent magnet (PM) installed in the area of the PC node, and connected to it by a constant magnetic field (PMF) and an alternating electromagnetic field (EMF) of a portable device (PP) containing the housing, the secondary a coil (VK), a driver, a rectifier / voltage / current regulator (VRNT), a charge controller (short circuit), a battery (battery) and an indicator that is connected by its input to the first port of the short circuit node, which is connected with its second to fourth ports , respectively, with the battery node and the first port of the VRNT node, with the second port of the VRNT node and with the second port of the driver node, which is connected to the second port of the VK node by the first port, which is connected to the third port of the VRNT node by the first port; with integrated permanent magnet area claimed in the VC node placement and configured to lock with each other housings PO and PP with built therein the permanent magnets (PM) and the wireless induction charging of the battery unit standard type Qi.

Functional diagram of this device is presented in figure 1. The system (Fig. 1) consists of a charging platform (ZP) 1, comprising a housing 3 with a permanent magnet (M1) 8 built into it, a power supply unit (BEP) 11, a current / voltage converter (PTN) 10, a primary coil (PC) 6, a current / voltage sensor (DTN) 5 and a charging platform controller (KZP) 4, which is connected with its first and second ports, respectively, to the first port of the PTN 10 and to the first port of the DTN 5, which is connected to the first port by the second port PC node 6, which is connected by the second port to the second port of the ПТН 10 node, which is connected by the third port with the second port of the BEP node 11, which the first port can be connected to the power supply network (220 V) 12, and connected to it by means of an alternating electromagnetic field (EMF) 7 and a constant magnetic field (PMF) 9 of a portable device (PP) 2 comprising a housing 13 with built-in permanent magnet (M2) 14, secondary coil (VK) 15, driver 16, rectifier / voltage / current regulator (VRNT) 19, charge controller (KZ) 17, battery (battery) 20 and indicator 18, which has its own input connected to the first port of KZ 13, which is its second to fourth ports and connected, respectively, to the battery assembly 20 and the first port of the BPHT node 19, to the second port of the BPHT node 19 and to the second port of the driver node 16, which is connected to the second port of the VK 15 node by the first port, which is connected to the third port of the BPHT node by the first port 19, at the same time, the device is made with the possibility of fixing the bodies 3 (ЗП 1) and 13 (ПП 2) between each other using the built-in permanent magnets, respectively, М1 8 and М2 14, and performing wireless induction charging of the battery assembly 20 according to the standard type Qi.

The system (figure 1) operates as follows. To carry out the charging procedure of the battery assembly 20, the housing 13 of the PP 2 assembly is placed / mounted directly on the housing 3 of the storage compartment 1, which performs the functions of a wireless induction charging device. To obtain a high level of efficiency of the WPT process (for example, high efficiency), the nodes of PC 6 and VK 15 should be as close as possible and correctly (according to the instructions, for example, coaxially) oriented relative to each other (usually opposite each other). To fix the mutual positioning of the PC 6 and VK 15 nodes performed by the user of the device when connecting the PP 2 to ZP 1, permanent magnets (M1 8 and M2 14) are used, integrated in the cases 3 (ZP 1) and 13 (PP 2). Under the action of the forces of the PMP 9, the body 13 of the PP 2 assembly is fixed on the housing 3 of the PS 1 assembly. In addition, the action of the PMP 9 forces partially helps to achieve the correct mutual positioning of the PS 1 and PA 2 nodes. Due to the action of the PMP 9 forces created by the M1 and M2 nodes , during the induction charging of the battery assembly 20, the orientation of the PO 1 and PP 2 nodes established by the operator / individual / user of the device is maintained. After connecting the PS 1 node to the supply network (220 V) 12, in the PC 6 node, which is an induction coil , from With the help of the PTN 10 unit, an alternating voltage / current is created, which leads to the formation of an electromagnetic field (EMF) 7 around the PC 6, which reaches and crosses the turns of the VK 15 coil. In this case, due to the effect of electromagnetic induction, an input electric the voltage (VEN), which is supplied to the VRNT node 19, with the help of which the VEN is converted / converted to the type / level necessary for charging the battery assembly 20, which occurs under the control of the KZ node 17. Thus, the electric The energy from the ЗП 1 unit is transmitted to the ПП 2 unit by means of an alternating electromagnetic field 7, which induces (due to electromagnetic induction) in the turns of the secondary coil 15 the value of the alternating voltage of the VEN sufficient to charge the battery unit 20. If the condition is satisfied that Since the primary and secondary coils (PC 6, VK 15 nodes) are in close proximity (the conditions for their positioning are met), a significant part of the power lines created by the PC 6 primary coil will pass through the turns of the VK 15 secondary coil, creating in th alternating current, which is then converted and used to charge the battery node 20. The WPT process of this device corresponds to the Qi standard specification known from the technology, which governs the protocol of energy and information interaction between the nodes ZP 1 and PP 2. At the same time, the information interaction is ZP 1 and PU 2 provides for the transfer of digital information in the form of bits / bytes by the method of phase modulation of EMF 7. Information communication between the nodes ZP 1 and PP 2 is established automatically, after the case 13 of the node P 2 is mounted on the surface of the housing 3 and the detected / identified node PO 1 (provided that the power supply units included). To identify the node PP 2, node PS 1 every 400 ms are sent / emitted by means of EMF 7 energy / electrical pulses. If PP 2 is installed on the housing 3 of the PS 1 unit, then an inter-node information exchange is activated, during which the PS 1 and PP 2 "agree" on the charging conditions of the battery assembly 20 (for example, the required amount of electricity, current strength and frequency). After this, the phase of the WPT process begins. To control this process, the PP 2 node sends data packets with information about errors in the operation of the wireless electric power transportation system to the PS 1 node every 32 ms. Data transfer from PP 2 to ZP 1 and vice versa is carried out along the circuit: KZ 17 - driver 16 - VK 15 - EMF 7 - PC 6 - DTN 5 - KZP 4. The process of charging the battery assembly 20 is displayed on indicator 18, for example, by the color of its glow or a conventional battery icon that changes the degree of filling / filling as the battery is charged 20. After the battery of the battery 20 is completed, the software 2 sends a data packet with a message like “Energy transfer completed”, upon receipt of which the power supply module 1 stops working (stops wireless transmission electricity).

This system partially eliminates the disadvantages of the previous technical solution. So, with the help of nodes М1 8 and М2 14, the fixing of ЗП 1 and ПП 2 nodes is ensured, which contributes to the more reliable than in the previous TR, preservation / retention of the user-installed mutual positioning of the PC 6 and VK 15 nodes during the implementation of the BIS of the battery assembly 20. Thanks to this, the creation and maintenance of favorable conditions for WPT is achieved. In addition, this device uses a more advanced mechanism for controlling WPT processes and charging the battery assembly 20. This is achieved through the use of a more reliable digital communication protocol between the nodes ZP 1 and PP 2, which provides the ability to detect and correct errors that occur during wireless transmission electricity, and perform monitoring of the completion of charging the battery node 20.

This system has inherent disadvantages similar to the previous technical solution. Especially, this device is vulnerable to external mechanical influences (shock, vibration), which can interfere with the mutual positioning of the PC 6 and VK 15 nodes and, thereby, cause a decrease in the WPT efficiency and cause a termination or a significant increase in the charging time of the battery assembly 20. It should also note that the presence of nodes M1 8 and M2 15 only partially contributes to the mutual positioning of the nodes PC 6 and VK 15 when placing the housing 13 on the housing 3, due to the presence of adhesion / friction forces between the surfaces of these buildings which the PMF 9 cannot overcome, and as a result, the mutual fixation of the housings 3 and 13 can occur with a displacement, that is, without exact coincidence of the magnetic lines of force of the PMP 9 created by the north and south poles of the magnets M1 8 and M2 15. Thus, when When using this device, situations are possible in which, after fixing the housings 3 and 13 using PMP 9, the mutual positioning of the PC 6 and VK 15 nodes may have low accuracy, and its increase (self-positioning using PMP 9 forces) is difficult due to the high adhesion level / s the clutch / friction between these bodies (ZP 1 and PP 2). In these situations, the efficiency of the WPT process can be significantly reduced and the set / set / required charging mode of the battery pack node 20 may be violated. Signs and properties, the use of which allows you to monitor the efficiency of the WPT and battery charge mode, as well as automatically, without the participation of individuals, position the PC nodes 6 and VK 15 with sufficient accuracy, that is, to eliminate the effects of external factors that cause disturbances in the mutual positioning of the PC 6 and VK 15 nodes, which reduce the efficiency of WPT and nar shayut mode inductive charging battery unit 20, a warning individuals of the emergency situations in which disrupted the process of BPE and / or impaired unit charging mode battery 20 in this device - no.

In the process of research, the authors found that the efficiency (reliability) of PEP power systems / devices that use wireless induction charging of the built-in battery can be improved by using new features and properties that automatically maintain optimal conditions for the BEP and battery charge modes achieved by improving the accuracy of the mutual positioning of the nodes ZP 1 and PP 2, and to provide notification to the operator / individual / user of the probes about the occurrence of emergency situations th (AU), which are accompanied by disturbances of the process and the BEP battery charging mode. At the same time, it can be assumed that a significant increase in the efficiency of the power supply system and the device as a whole can be achieved by using the device’s capabilities automatically, without the participation of individuals, to configure the relative positions of the PC 6 (ZP 1) and VK 15 (PP 2) nodes sufficient accuracy to achieve high efficiency of the WPT process. This will make it possible to compensate for the positioning errors of the device that may occur during the connection / connection of the RFP 1 and PP 2 nodes, as well as compensate / eliminate violations in the positioning of these nodes caused by external factors such as shock / vibration during operation of the device. Also, it can be assumed that the availability of capabilities to control the WPT efficiency in the process of charging the battery assembly 20 with the formation of acoustic / sound signals emitted by the device in the event of an AS that cannot be eliminated automatically by the device resources allows the user / device operator to take timely measures to the elimination of the reasons affecting the induction charging of the battery assembly 20. Especially, the aforementioned capabilities of the device will be in demand and are important during its operation in the CCSS, where the appearance of external x mechanical influences is most likely, and the presence of the device’s ability to self-restore working capacity without user intervention, that is, performing automatic adjustment / positioning of the PC 6 (ZP 1) and VK 15 (PP 2) nodes for the rehabilitation of the WPT process and setting the normal / preset inductive mode charging the battery assembly 20 after the occurrence of the speaker will significantly increase its efficiency.

Studies have shown that the use of continuous monitoring of the WPT process and control of the induction charging mode of the battery with the possibility of detecting emergency situations (AC) in which the current efficiency of the WPT decreases below the permissible value, for example, due to violations of the mutual positioning of the transmitter and the energy receiver and automatic, without the participation of an individual / user of the device, elimination of the speakers with the restoration of the WPT process with an efficiency sufficient to support the required / specified charging mode of the AK unit B, by automatically optimizing / adjusting the mutual orientation of the transmitter and the energy receiver, performed by physically moving / displacing the transmitter and receiver bodies relative to each other under the action, on the one hand, created by the device of the mechanical vibrations of the transmitter and receiver bodies dosed in time and intensity of action energy, providing compensation / elimination / reduction of friction forces between the transmitter and the receiver, and, on the other hand, the forces of a constant of a magnetic field created by permanent magnets, which are integrated / integrated into the transmitter and receiver housing, as well as the formation and emission of acoustic signals necessary to attract the attention of the user / individual / operator of the device in cases of speaker systems in which the WPT and battery charge processes are not can be automatically tuned / restored with the required accuracy without the participation of PL, not known from the technique.

The purpose of the utility model is to expand the functionality of the known device related to increasing the efficiency of monitoring and controlling the process of wireless power transmission and automatically maintaining the required / specified modes of induction charging of the battery.

This goal is achieved due to the fact that in the known device, consisting of a charging platform (ZP), comprising a housing, power supply unit (BEP), a current / voltage converter (PTN) type AC-DC, a primary coil (PC), a current sensor / voltage (DTN) and the charging platform controller (KZP), which is connected with its first and second ports, respectively, to the first port of the PTN node and to the first port of the DTN node, which is connected with its second port to the first port of the PC node, which is connected to the second port with the second port of the PTN node, which is the third the mouth is connected to the second port of the BEP node, which is configured to connect its first port to a 220 V power supply network and connected to it via a wireless (inductive) communication portable device (PP) containing a housing, a secondary coil (VK), a driver, a rectifier / voltage / current regulator (VRNT), charge controller (short circuit), battery (battery) and an indicator that is connected with its input to the first port of the short circuit node, which is connected with its second to fourth ports, respectively, with the battery node and the first port of the node VRNT, about the second port of the VRNT node and with the second port of the driver node, which is connected to the second port of the VK node by the first port, which is connected to the third port of the VRNT node by the first port, and which is capable of fixing the cases of the charging platform and the portable device using the built-in of permanent magnets and the implementation of wireless induction charging of the battery assembly according to the type standard, an additional vibration element (VE) and an acoustic emitter (AI) are introduced into the RF assembly, which is connected to the third port of the K node by its input ZP, which is connected to the port of the VE node by the fourth port, and the KZP node operates according to the program that provides continuous monitoring of the WPT process and control of the battery charging mode with the possibility of detecting emergency situations (AC), in which the current WPT efficiency decreases below the permissible value and / or the charging mode of the battery node is violated, for example, due to violations of the mutual positioning of the PC and VK nodes, elimination of AS without the participation of individuals using the automatic positioning procedure (PAP) of the PC and VK nodes, rehabilitating to it / restoring the WPT process with an efficiency sufficient to support the given / required charging mode of the battery assembly, performed by physically displacing / displacing the housings of the air conditioner and the spacecraft relative to each other using the air conditioner unit, which creates the mechanical vibrations of the body of the air conditioner unit dosed in time and intensity together with PP installed on it) providing compensation / elimination / reduction of friction forces between the bodies of the ZP and PP nodes and, thereby, creating conditions for their movement relative to each other and accurate in the borrowed positioning of the PC and VK nodes under the action of the forces of the permanent magnetic field of the PMF created by the nodes M1 and M2, and the completion of the PAP after reaching such an orientation of the PC and VK nodes at which the current WPT efficiency reaches a level / value sufficient to support a given / set charge mode the battery node, as well as the activation of the AI node, made with the possibility of emitting acoustic / sound signals to attract the attention of the user / individual / operator of the device in cases of speakers, in which BPE processes and battery charge mode can not be automatically using PAP, configured / restored at the desired efficiency, for example, due to the large removal towers RFP and PP.

The functional diagram of the device for induction charging of the battery of a portable device (hereinafter referred to as the device) is shown in FIG. The device (figure 2) consists of a charging platform (ZP) 1, comprising a housing 3 with an integrated permanent magnet M1 8, a power supply unit (BEP) 13, an acoustic emitter (AI) 12, a current / voltage converter (PTN) 11, a vibration element (VE) 10, a primary coil (PC) 6, a current / voltage sensor (DTN) 5 and a charging platform controller (KZP) 4, which is connected with its fourth, third, first and second ports to the port of AI 12, with the port node VE 10, with the first port node PTN 11 and the first port of the node DTN 5, which is connected to the second port with the first port of the host PC 6, which is connected by the second port to the second port of the ПТН 11 host, which is connected by the third port to the second port of the BEP 13, which is configured to connect its first port to the power supply network (220 V) 14, and connected to it via wireless (inductive) coupling (by means of an electromagnetic field - EMF 7) of a portable device (PP) 2 comprising a housing 16, a secondary coil (VK) 17, a driver 18, a rectifier / voltage / current regulator (VRNT) 21, a charge controller (KZ) 19 , battery (battery) 22 and indicator 20, which its input is connected to the first port of the KZ 19 node, which, with its second to fourth ports, is connected, respectively, to the battery assembly 22 and the first port of the BPHT 21, to the second port of the BPHT 21 and to the second port of the driver 18, which is connected to the first port with the second port of the VK 17 node, which is connected to the third port of the VRNT 21 node by the first port and configured to fix the housings 3 and 16 with each other using the permanent magnets M1 8 and M2 15 installed in them in the area of the node PC 6 and VK 17, and implemented QI of the wireless induction charging unit of the battery 22 according to the Qi type standard, in addition, the AI 12 unit is configured to generate and emit sound signals used to alert / attract the attention of the device user about the occurrence of violations of the induction charging of the battery unit 22, for example, in the case of termination of the wireless electric power transmission (BPE), KZP node 4 operates according to the program providing continuous monitoring of the WPT process efficiency and control of the battery charging mode during its induction charging with monitoring / detection of emergency situations (AS), in the event of which the current efficiency of the WPT and / or the charging mode of the battery assembly decreases below the permissible value, for example, due to violations of the rules / conditions for the placement / positioning of the nodes ZP 1 and PP 2 (nodes of PC 6 and VK 17), and activation of the automatic positioning procedure (PAP) of the PC 6 and VK 17 nodes, which ensures the elimination of arising AS without involving / participation of individuals, by creating using the VE node 10 mechanical vibrations dosed by time and intensity of action case 3 (unit ЗП 1), on which case 16 (unit ПП 2) is mounted / fixed, compensating / decreasing the adhesion / adhesion / friction force between these cases and creating conditions for their (buildings 3 and 16) physical movement relative to each other under the action of the forces of the constant magnetic field of the PMF 9 formed by the nodes M1 8 and M2 15, and the completion of the PAP after reaching such an orientation of the nodes of the PC 6 and VK 17, at which the current WPT efficiency reaches a level / value sufficient to support a given / set charge mode of the battery node 22, and that the activation unit 12 AI in cases of such speakers that can not be eliminated automatically (via PAP), without the participation of an individual / user devices.

The device (figure 2) functions similarly to the prototype. The user of the device for carrying out induction charging of the battery assembly 22 places the housing 16 on the housing 3. At the same time, under the influence of the attractive magnetic field (PMF) 9 created by the permanent magnets M1 8 and M2 15, which are built into the housings 3 and 16, respectively It ensures the fixing of the charging platform ЗП 1 and the portable device ПП 2. After installation of the housing 16 of the ПУ 2 assembly on the housing 3 of the ЗП 1 assembly, it is identified as a device in accordance with the standard protocol provided for by the specification for Qi devices. At this stage, between the PU 2 and ZP 1, energy (for the WPT channel) and communication (for the service information exchange channel) communication is established. Using magnets M1 8 and M2 15, respectively integrated in the housing 3 and housing 16, a “rough” mutual positioning and fixing of the PP 2 and ZP 1 nodes is ensured. In this case, the PC 6 and VK 17 nodes must be located opposite each other at the minimum distance, which provides optimal conditions for the implementation of the WPT and induction charging of the battery assembly 22, which is carried out according to the specification of the standard If, when connecting the PP 2 unit to the PS 1 unit, violations of their mutual positioning are possible (for example, due to the carelessness of the device user) or and in the process of induction charging, the device is subjected to external mechanical influences such as shock or intense vibrations, in which the mutual orientation / positioning of the PC 6 and VK 17 nodes is violated so that speakers appear, leading to a decrease in the WPT efficiency and / or a change (termination) of the charging mode of the battery 22 unit, then the KZP 4 node, which provides constant monitoring of the WPT process efficiency during the induction charging of the battery 22, the PAP is launched - the procedure for automatic (without user intervention) settings / subst oyki / optimization / clarify the mutual orientation of the RFP units 1 and PP 2 (PC nodes 6 and VC 17). To do this, the KZP node 3 activates the VE 10 node, with the help of which the mechanical vibrations of the case 3 (unit of the ЗП 1), on which the case 16 is installed / fixed (the ПП 2 node), providing compensation / elimination / are created / reduction of adhesion / adhesion / friction forces between buildings 3 and 16 (nodes ZP 1 and PP 2). This creates the conditions for physical micromoving (about 1 mm) of the cases ЗП 1 and ПП 2 relative to each other under the action of the forces of the constant magnetic field ППМ 9 created by the nodes М1 8 and М2 15. Figuratively speaking, vibration occurs on every first half-cycle, as if “Tossing” the case 16, but it does not “fly away”, because it is held by the forces of gravity and the PMF 9. Then, on every second half-cycle of vibrations, the “fall” of the housing 16 occurs with a displacement caused by the action of the force of the PMP 9, which has a gradient (directivity of magnetic force lines), org analyzed in such a way that the attractive forces tend to fix the nodes M1 8 and M2 15 strictly in a certain / predetermined position, for example, opposite each other poles of these magnets. When this orientation is achieved, the nodes M1 8 and M2 15 integrated in the housings 3 and 16, the necessary mutual positioning of the nodes PC 6 and VK 15 is also provided. Thus, the use of vibrations of the housings 3 and 16 in combination with the action of the forces of the PMF 9 makes it possible to perform automatic, without operator intervention, mutual positioning of the PC 6 and VK 15 nodes with high accuracy, which is a sufficient condition for ensuring high WPT efficiency and maintaining the established / required charging mode of the battery assembly 22. At the same time, PAP is completed after the orientation of the PC 6 and VK 17 nodes is reached, at which the current WPT efficiency reaches a level / value sufficient to support the given / set charge mode of the battery assembly 22, when there are speakers that cannot be eliminated by the device’s resources, i.e. , in cases of the occurrence of such speakers that cannot be eliminated automatically using PAP, for example, in cases of significant removal of buildings 2 and 16 from each other, the KZP node 4 activates the AI node 12, which ensures the formation of a horn / sound signals signaling (attracting the attention of individuals) about the occurrence of faults in the induction charging system of the device.

The technical result achieved when using this device is to increase the reliability of inductive charging of the battery (IZAB) due to constant monitoring and automatic maintenance of conditions that ensure a high level of efficiency of the IED (high accuracy of positioning of PC 6 and VK 17 nodes). This is achieved by constantly monitoring the effectiveness of the ISAB with the identification of emergency situations (AC), in which the current value of the effectiveness of the ISAB decreases below the permissible value and / or the set / specified charging mode of the battery assembly 22 is violated, with the subsequent elimination of the arising AS using the PAP that implements accurate positioning nodes of PC 6 and VK 17 and performed without the participation of individuals, as well as the generation / emission of acoustic signals (using the AC 12 node) to timely attract the attention of individuals about ah of such speakers that can not be eliminated automatically (via PAP).

In the proposed device, the induction charging of the battery of a portable device (hereinafter - the device) provides the following combination of distinctive features and properties.

The vibrating element (VE) 10 and acoustic emitter (AI) 12, which is connected to the third port of the KZP node 4, which is connected to the port of the VE 10 node by the fourth port, are additionally introduced into the charging platform of the power supply unit 1 of the device.

Node KZP 4 operates according to the program providing constant monitoring of the WPT process and control of the charging mode of the battery 22 unit with the possibility of detecting emergency situations (AC), in which the current efficiency of the WPT decreases below the permissible value and / or the charging mode of the battery 22 unit is violated, for example, for violations of the mutual positioning of the PC 6 and VK 17 nodes, elimination of AS without the participation of individuals using the automatic positioning procedure (PAP) of the PC 6 and VK 17 nodes, which rehabilitates / restores the WPT process with efficiency sufficient to support the specified / required charging mode of the battery assembly 22, performed by physically displacing / moving the housings ЗП and ПП relative to each other with the help of the unit ВЭ 10, which creates the mechanical vibrations of the case of the unit ЗП 1 dosed in time and intensity (together with installed on it PP 2), providing compensation / elimination / reduction of friction forces between the housings 3 and 16 (nodes ZP 1 and PP 2) and, thereby, creating conditions for their movement relative to each other and accurate mutual positioning of the nodes PC 6 and VK 17 by the action of the forces of the constant magnetic field of the PMF 9 created by the nodes M1 8 and M2 15, the completion of the PAP after reaching such an orientation of the PC 6 and VK 17 nodes, at which the current WPT efficiency reaches a level / value sufficient to support the given / set charge mode of the battery assembly 22 , and activation of the AI 12 node, which emits acoustic / sound signals to attract the attention of the user / individual / operator of the device in cases of emergence of AS, in which the WPT processes and the charge mode of the battery node 22 cannot be automatically matically by PAP, configured / restored at the desired efficiency, for example, because of the large deletion housings 1 PO and PP 2.

The introduction and use of these signs and properties can significantly expand the functionality of the known device associated with increasing the efficiency of monitoring and control of the process of wireless power transmission and automatic maintenance of the required / specified modes of induction charging of the battery.

The combination of distinctive features and properties of the proposed device for the induction charging of the battery of a portable device is not known from the technology, therefore it meets the criterion of novelty. At the same time, to achieve the maximum effect on expanding the functionality of the known device, aimed at increasing the efficiency of monitoring the process of wireless transmission of electric energy and automatically supporting the required / specified modes of induction charging of the battery, it is necessary to use the whole set of distinguishing features and properties mentioned above.
