Description

The invention relates to devices for servicing and maintaining electric batteries, in particular rechargeable batteries, in particular: lead starter batteries with a capacity of up to 200 A / hour.
A known complex charge and training of batteries, containing a table with cells for batteries (AB), equipped with contacts for connecting to a power source, and batteries. The table consists of a metal frame on the legs, and the table top is made in the form of a roller table, consisting of independent sections in the number of ABs, each section of the roller table is mounted in the frame on a corresponding pallet, in addition, the rack is equipped with side and rear walls, which are combined with a transparent cover with the formation of a closed volume, reclining to the rear wall, and an air duct for connecting to an exhaust fan installed under the roller tables. In addition, the complex contains a common power source, a voltmeter connected to its output; charging cells are connected in parallel with the power source; charge-discharge switches, connected in series with the batteries; load rheostat; ammeter; circuit breakers. The complex allows, through the charge-discharge switches, which are switched manually, to carry out a charge of the battery at a constant value of the charging current, as well as carry out a control and training cycle (training the battery) by alternately charging, discharging, and charging the battery. In the known complex, the battery charge begins immediately after it is connected to a power source and stops immediately after it is turned off. The magnitude of the required voltage is supported by a voltmeter. The magnitude of the charging current is set by the ammeter at the beginning of the charge of the battery by means of a load rheostat ("Lead starter batteries" / Manual / approved deputy head of the Main Armored Directorate and deputy head of the Autotractor Directorate, M .: Military Publishing House of the USSR Ministry of Defense, 1983 fig. 41, p. 51; fig. 42 p. 52).
The main disadvantage of the known complex, first of all, is the lack of indication of the results of monitoring the state of the battery, as well as the lack of control directly in the rack, namely voltage sensors and electrolyte temperature sensors, which reduces the efficiency of monitoring the battery charge / discharge process, and therefore worsens the battery charge / discharge conditions and reduces their service life. In addition, the known complex is made with the ability to manually control the charge / discharge process of the battery, which does not allow to respond quickly to changes in the mode of the charge / discharge process of the battery, and also introduces a subjective factor into the charge / discharge process and, therefore, worsens the conditions of the charge / discharge and reduces the life of the battery, and, in addition, reduces the safety of operation, as it creates conditions for violation of the charge / discharge mode of the battery. At the same time, since the duct for connecting to the exhaust fan is installed under the roller tables, as a result, when boiling electrolyte, only heavy vapors get into the duct, and the hydrogen component remains at the top under the cover of the rack. It also increases the risk of working with the rack.
Thus, the disadvantage of the known complex is the impossibility of automatic monitoring of the state of the battery as a whole, and of individual batteries of the battery in the process of charge and discharge, the inability to automatically control the process of charge and discharge, as well as reducing the safety of working with the complex.
Closest to the proposed one is an automated hardware-software-electromechanical complex for charging and training batteries, containing power supplies by the number of batteries, a rack with cells for batteries (batteries), which are equipped with contacts for connecting to a power source, batteries, a voltage sensor installed with the ability to alternately measure the voltage at the terminals of the AB, discharge circuits and a program-electromechanical device for controlling the charge / discharge of the AB, I include its a hardware-setting device and an electromechanical device (AS USSR №729701, N01M 10/48, 25.04.80).
The disadvantage of the known complex is, first of all, in that it does not allow the operation of charging and training electrolyte batteries. This is due to the fact that in the rack of the complex there is no ventilation system necessary when charging electrolyte batteries, in which the electrolyte emits toxic fumes during overheating. In addition, the known complex does not provide for the possibility of measuring the temperature of the electrolyte to prevent overheating, as well as the ability to measure and control the voltage on individual battery batteries, which is also necessary when charging electrolyte batteries. In this case, the alternate measurement of the voltage on the battery by electromechanical control of the charge / discharge process, as well as the sequence of measurement of the voltage on the battery, creates conditions for recharging the battery and other undesirable situations due to the time delay that occurs, which worsens the charge / discharge conditions of the battery and reduces their service life. In addition, the implementation of the well-known complex with program-electromechanical control of the battery charge / discharge process worsens the battery charge / discharge conditions due to the presence of transition contacts of the electromechanical part, switching wires, step relay switching elements, since in this case the necessary charge / discharge process control AB occurs with a time delay. The latter also determines the possibility of recharging the battery and the occurrence of other undesirable situations, which not only worsens the battery charge / discharge conditions, but also increases the risk of working with the complex due to the possibility of emergency situations with the battery due to non-compliance with the charge / discharge mode. In addition, in the well-known complex, the work of the program-setting device is strictly regulated by the software product embedded in it, which does not allow the operator to participate, i.e. excludes the possibility of working in interactive mode: the operator is a software-setting device, and therefore, does not allow changing the AB control order, performing real-time selective control of the battery charge / discharge process, and also eliminates the possibility of real-time constant monitoring of the battery maintenance process . As a result, the efficiency and information content of the control system is reduced, and therefore, the conditions of charge / discharge of the batteries are worsened and their service life is reduced. In addition, the ability to control the charge / discharge of the battery only at programmed time points requires an accurate calculation of the time to avoid overcharging the battery and the occurrence of other undesirable situations, which is impossible in principle when using an electromechanical control system. Moreover, since the known device uses an AA charge with a time-varying current at constant voltage, and the system is controlled by software in a mode that does not provide for a dialogue mode, careful elimination of emergency conditions by the degree of initial AA discharge is necessary to exclude emergency situations to obtain the same initial conditions for setting the charging current and further control of the charge / discharge, which complicates the work with the known complex and worsens the battery charge conditions.
Thus, the closest to the proposed complex for charging and training batteries during the patent search does not allow to achieve a technical result consisting in the possibility of performing operations of charging and training electrolyte batteries, in the possibility of programmed control of the battery charge / discharge process, in improving conditions of a charge of AB and in increase of safety of work.
The claimed invention solves the problem of creating an automated software and hardware complex for charging and training batteries, the implementation of which allows us to achieve a technical result, which consists in the possibility of performing operations of charging and training electrolyte batteries, in the possibility of programmed control of the charge / discharge of batteries, in improving the battery charge conditions and to improve work safety.
The essence of the claimed invention lies in the fact that in the automated software and hardware complex for charging and training batteries "Prism", containing power sources by the number of batteries, a rack with cells for batteries (batteries), equipped with contacts for connecting to a power source, batteries batteries, discharge circuits, and a battery charge / discharge control software, the new thing is that the power supplies are made pulse program-controlled, and the discharge circuits are made in the form lock of discharge resistors, the rack is made in the form of a table, which consists of a metal frame on the legs, which is grounded, with a table top made in the form of a roller table, consisting of independent sections according to the number of ABs, with each section of the roller table installed in the frame on a corresponding pallet, except moreover, the rack is provided with side and rear walls, which are combined by a lid with the formation of a closed volume, reclining to the rear wall, and the side walls and the lid are made of transparent material; in addition, the rack is equipped with an air duct for connecting to an exhaust fan, which is fixed outside the rear wall, while the air duct is in communication with the upper part of the internal space of the closed volume and with the space under the roller tables, in addition, program-controlled measuring adapters for the number of slots for ABs, which are located on the rear wall of the rack above the level of the closed cover, the adapter outputs are equipped with cables for connecting to the interface, and each measuring adapter is equipped with an in diction, showing the state of AB: inclusion; charge; discharge; blocking; battery charge scale; Work; the presence of communication over the charge / discharge control network; in addition, according to the number of AB slots, voltage sensors and electrolyte temperature sensors were inserted into the rack, the outputs of which are connected to the inputs of the corresponding adapters, voltage sensors installed with the ability to measure voltage both on the battery and on individual battery batteries, and the electrolyte temperature sensors are installed in each battery in the average battery in the hole for filling the electrolyte, while the inputs and outputs of the power sources, inputs and outputs of the measuring adapter and the block of discharge resistors through the interface s with the programming device controlling charging / discharging of the rechargeable battery, which consists of a system controller and a personal electronic computer (PC), wherein in each module the power supply output and the output of unit discharge resistors are connected and are connected to respective input AB. In addition, the block of discharge resistors contains n resistors, where n = 2, 3, ..., and is made with the possibility of their software connection in various configurations, and the power source is multi-channel with the possibility of program channel selection.
The technical result is achieved as follows.
The presence of a table with cells for rechargeable batteries (AB), equipped with contacts for connecting to a power source, provides the ability to connect the battery to the power source and the ability to install monitoring equipment individually for each battery, which makes it possible to charge / discharge the battery. Since the table consists of a metal frame with legs, it ensures rigidity and reliability of the structure, which withstands heavy loads. In addition, the implementation of the metal frame allows you to ground the table, which eliminates the voltage of maintenance personnel. All this increases the safety of working with the rack.
The implementation of the tabletop in the form of a roller table, consisting of independent sections according to the number of batteries, makes it easy to install both a heavy battery in the cell and remove it from it, which reduces the risk of working with the rack.
Since each section of the roller table is mounted in the frame on a corresponding pan, the electrolyte sprayed during boiling drains into the pan, which reduces the risk of working with the rack. Moreover, due to the fact that the rack is equipped with side and rear walls made of transparent material, which are combined with a lid to form a closed volume, the operation of the rack is also safe, as it provides the possibility of visual monitoring of the charge / discharge process, protection of service personnel from sprayed when boiling electrolyte and toxic vapors released during this. In addition, the implementation of the side walls and the cover of a transparent material provides the ability to visually monitor the charge / discharge process by monitoring devices, which also increases the safety of working with the rack and provides the ability to quickly monitor the charge / discharge process of the battery. The latter improves the battery charge conditions, provides a gentle charge mode and, thereby, extends the battery life.
The implementation of the cover reclining to the rear wall provides free space in front of the battery and free access to the battery, which increases the safety of working with the rack.
An air duct for connecting to an exhaust fan ensures the extraction of toxic fumes from the closed volume of the rack with the lid closed. Due to the fact that the duct for connecting to the exhaust fan is fixed outside the rear wall of the rack, free access for visual inspection and repair is provided, which increases the safety of working with the rack. Due to the fact that the duct is in communication with the upper part of the internal closed volume under the cover of the rack and with the space under the roller tables, when electrolyte boils, both heavy acid fumes accumulating under the roller tables and the hydrogen component that accumulates at the top of the closed volume under the cover of the rack get into the duct, which increases the safety of working with the rack.
The implementation of the software device for controlling the charge / discharge of the battery from the system controller and personal electronic computer (PC), as well as the introduction of the rack software-controlled measuring adapters, the outputs of which are configured to connect to the interface, provides the ability to programmatically control the charge / discharge process of the battery. As a result, this allows the battery charge / discharge to be performed in software, which makes it possible to control the battery charge / discharge mode both at programmed time points and selectively at the operator’s discretion, i.e. the ability to continuously monitor the charge / discharge process of the battery, its individual batteries. At the same time, the volume of information is expanding, which allows making operational decisions to exclude recharging the battery and the occurrence of other undesirable situations. This provides a sparing mode of maintenance of the battery and extends its service life.
The introduction of electrolyte temperature sensors installed in the middle battery into the hole for filling the electrolyte, the outputs of which are connected to the inputs of the corresponding adapters, makes it possible to perform charge / discharge operations of electrolyte batteries, since this allows you to control the temperature of the electrolyte during the battery charge in real time, which allows timely prevent boiling of the electrolyte AB and improves the conditions of the charge of the battery, providing a sparing mode of charge of the battery, and therefore, extends the life AB service.
The introduction of a voltage sensor installed with the ability to measure voltage on the battery, as well as the voltage on individual batteries of the battery in the control-training cycle, allows you to continuously measure and monitor the voltage change in real time, which allows you to timely prevent overcharging the battery and improves the battery charge conditions, provides a sparing mode of a charge of AB, and therefore, prolongs their service life. In addition, the ability to control voltage changes allows the claimed complex to perform battery charge at a constant value of the charging current. Using this method of charging the batteries while servicing several batteries simplifies their selection into groups, since in this case the batteries are selected according to only one criterion, namely, according to the operating voltage of the battery, which reduces the likelihood of improperly choosing the battery charge / discharge mode and improves charging conditions AB, extending their lifespan.
The program-controlled measuring adapter, thanks to the declared connections with the outputs of the voltage sensor and the electrolyte temperature sensor, converts the output signals from their outputs into a digital code. As a result, it is possible to enter information on the electrolyte temperature and voltage on the batteries or batteries of the batteries through the interface in the control software device, as well as on the correct connection of the batteries. Due to the fact that the measuring adapter is equipped with a display panel, configured to display information: inclusion; charge; charge; blocking; battery charge scale; Work; network connectivity; provides the possibility of visual operational control of the maintenance of the battery, which also provides a gentle battery charge mode.
Due to the fact that the control software device consists of a system controller and an operator control panel in the claimed system, real-time possibility of mixed control of the battery charge complex is provided, namely: with the participation of the PC operator — interactive mode, or fully automatic mode — software . At the same time, in the dialogue mode, it is possible to obtain graphical and quantitative information directly on the PC display screen. The presence of the dialogue mode provides the possibility of changing the order of control and monitoring the operation of the complex, which, in turn, allows selective control of not only the final results of the charging process, but also the intermediate stages, which expands information on the charge / discharge mode of the battery and provides a gentle mode the battery charge / discharge process, increases their service life, compared with the prototype. Combining program control with controlling the charge / discharge process by means of an operator expands the system's functionality when servicing the battery, as it allows you to select and monitor the general condition or parameter of interest at any time in real time not only the battery itself, but also any of the batteries included in it . The ability to graphically and quantitatively display the state of the battery gives a complete picture of the state of the battery in real time.
Moreover, the presence of the dialogue mode allows you to control the battery charge / discharge mode not only at programmed time points, but also selectively at the discretion of the operator. The ability to continuously monitor the battery charge / discharge process, its individual batteries provides a sparing mode of battery maintenance and extends its service life. At the same time, the range of monitored parameters is expanding, which provides a sufficient amount of information that allows you to make operational decisions to avoid overcharging the battery and the occurrence of other undesirable situations. It also provides a gentle battery charge mode.
The introduction of a voltage sensor connected to the battery with the ability to measure voltage on the battery, as well as the voltage on the individual batteries of the battery in the control and training cycle, allows you to continuously measure and control the voltage on them, which, in turn, allows you to complex to charge the battery at a constant charge current. With this method of charging the battery, the magnitude of the charging current is kept constant. As a result, while servicing the batteries, their selection into groups is simplified, since in this case the batteries are selected according to only one criterion: according to the operating voltage of the battery, in contrast to the prototype, where the batteries are grouped by operating voltage and the amount of battery discharged. This simplifies the maintenance of the battery when setting the charge / discharge mode and reduces the likelihood of overcharging the battery, which provides sparing service conditions for the battery and, therefore, extends their service life.
The implementation of a pulsed power source allows for low voltage to have large charge / discharge currents, which allows you to charge powerful starter batteries.
The presence of a discharge device and an electrolyte temperature sensor makes it possible for electrolyte batteries to carry out a control and training cycle (battery training): a full battery charge, a control discharge, and a final battery charge. This allows you to determine the residual capacity of the battery, and therefore, evaluate the performance of the battery and set the charge mode correctly, which extends the life of the battery.
The implementation of the discharge device in the form of a block of discharge resistors, which contains n resistors, where n = 2, 3, ..., with the possibility of their software connection in various configurations, allows, through communication with the system controller via the interface, to form a discharge circuit with the required resistance value for a specific AB, which provides a gentle battery charge mode, and, in addition, unifies the discharge device, and therefore the complex as a whole.
The execution of the power supply program-controlled allows you to fully automate the battery charge / discharge process. Moreover, in conjunction with the proposed embodiment of the discharge device, this allows the charge and the control and training cycle to be performed simultaneously by several powerful electrolyte batteries with the provision of the electrical modes required for each battery.
Thus, from the foregoing, it follows that the introduction into the complex of software-controlled measuring adapters installed in the rack by the number of AB sockets, the outputs of which are equipped with cables for connecting to the interface, and also by introducing voltage sensors and electrolyte temperature sensors by the number of AB sockets, the outputs of which are connected to the inputs of the respective adapters, and voltage sensors are installed with the ability to measure voltage both on the battery and on individual batteries of the battery, and the temperature sensors trolita installed in each AB average battery into the opening for pouring an electrolyte, and a power supply performance of the program-controlled not only make the process of charge / discharge AB fully software-controlled but also perform a charge electrolyte battery, including powerful. Moreover, the execution of the control software device consisting of a system controller and a PC provides control mobility due to the possibility of using the dialogue mode in the control. As a result of the possibility of obtaining current information about the state of the battery in graphical form on the display screen in real time: the results of selective or continuous monitoring of the battery charge process, the number of monitored parameters increases, and it is also possible to perform selective control of the parameters of the charge / discharge mode of individual batteries in real time. This allows you to create a sparing charge / discharge mode for the battery, which extends their service life.
In addition, the ability to work in interactive mode allows you to expand the amount of information in the reporting documents of accounting and the technical condition of the battery, which also increases the battery life.
From the above it follows that the claimed automated software and hardware complex for charging and training batteries “Prism” during implementation ensures the achievement of a technical result consisting in the possibility of performing operations of charging and training electrolyte batteries, in the possibility of programmed control of the battery charge / discharge process, improving battery conditions and improving operational safety.
In Fig.1 shows a rack for charging and training batteries (side view); figure 2 is a front view of the rack (simplified); figure 3 is a block diagram explaining the connection of the hardware of the complex with a software device for controlling the charge / discharge of AB.
The rack for charging and training batteries contains a table 1 with cells 2 for batteries (AB), equipped with contacts 3 for connecting to a power source (not shown), and batteries 4. Wiring of power cables is not shown. Table 1 consists of a metal frame on the legs, and the table top is made in the form of a live roll 5, consisting of independent sections in the number of AB 4. Each section of the live roll 5 is mounted in the frame on a corresponding pallet 6. The rack is equipped with side 7 and rear 8 walls, which are joined by a cover 9 with the formation of a closed volume, reclining to the rear wall 8. The side walls 7 and the cover 9 are made of transparent material. The frame of the table is grounded. Outside the rear wall 8, an air duct 10 is fixed for connection to an exhaust fan. The duct 10 is communicated through the respective shutters 11 and 12 with the upper part of the inner space of the enclosed space and with the space under the roller tables 5. Software-controlled measuring adapters 13 are inserted into the rack by the number of slots 2 for the battery 4, equipped with indication panels 14. Adapters 13 and indication panels 14 are located on the rear wall 8 of the rack above the level of the closed cover 9. The outputs of the adapters 13 are provided with cables for connecting to an interface (not shown). On the display panels 14, the status of AB 4 is displayed: on; charge; discharge; blocking; battery charge scale; Work; the presence of communication over the charge / discharge control network. The voltage sensors 17 and the electrolyte temperature sensors 18 are connected to the inputs of the respective adapters 13 through the sockets 15 and 16, respectively. Voltage sensors are installed with the ability to measure voltage on both AB 4 and on separate batteries of AB 4. Electrolyte temperature sensors are installed in each AB 4 on the average battery in the hole for filling the electrolyte.
In the embodiment of the rack, the display panels 14 and sockets 15, 16 are connected to the adapters 13 through the cable channel 19, made in the form of a rectangular pipe mounted on the rear wall 8 of the rack under the adapters 13 and the display panels 14.
The position of the AB 4 in cell 2 fixes the stop 20.
In addition, the complex contains (Fig. 3) a software charge / discharge control device AB, which consists of a system controller 21 and a personal electronic computer 22 (PC); a power source 23, which is made multi-channel with the possibility of program channel selection; the block of bit resistors 24. The block of bit resistors contains n resistors, where n = 2, 3, ..., and is made with the possibility of their software connection in various configurations.
For each battery, the output of the power supply 23 and the output of the block of discharge resistors 24 are connected and connected to the input of the corresponding battery 4. The inputs and outputs of the power supplies 23, the inputs and outputs of the measuring adapter 13 and the block of discharge resistors 24 are connected via interface 25 to the system controller 21 and the PC 22.
For the interaction of the hardware of the claimed automated software and hardware complex for charging and training batteries "Prism" as the interface 25 can be used, for example, the RS-485 Modbus Rtu interface.
As a system controller 21 and PC 22, for example, a Pentium IV type personal computer can be used.
The control software device — the system controller 21 and the PC 22 — is designed to control the hardware and software system for charging and training the rechargeable batteries, which, when the system is executed, allows real-time maintenance of up to 160 AB in a fully automatic mode. In the claimed complex, the software control device (system controller 21 and PC 22) allows in the automatic mode after connecting the AB 4 to perform: AB correctness control; auto detect plug-in battery (12V 24); control of the temperature of the electrolyte and protection against overheating of the battery by means of automatic shutdown of the battery; calculation of the time to perform a charge or discharge AB; determination of approximate battery capacity; auto-correction of the input electrolyte density depending on the temperature of the electrolyte; voltage control at the terminals and batteries of the battery at the CTC; automatic transition from the current of the first to the current of the second stage; control of the minimum and maximum voltage values at the terminals and batteries of the battery at the CTC with automatic shutdown of the battery; AB charge logging control the time of connecting the battery; control of battery charge / discharge time; indication of a charge level of AB; monitoring the availability of communication with the system controller and the block of charging resistors; graphical display on the computer display of the status of each of the batteries; and receive additional information, such as electrolyte density.
The whole battery charge / discharge process is fully automated and stops when the battery is charged or discharged or when an emergency occurs, such as: electrolyte overheating; overvoltage at the terminals of the AB or its sections; too low voltage at the terminals of the AB; Inadmissible voltage value between AB batteries in the CTC mode and the included battery monitoring.
In addition, the control device has the ability to manually replenish the battery base, change the parameters of their charge / discharge in relation to charge / discharge currents, battery capacity, the ability to periodically (once a year) calibrate the channels to improve the accuracy of voltage and temperature measurements, the ability to reconfigure the port in case of parameter changes via the RS-485 Modbus Rtu interface.
A program-controlled measuring adapter 13 is a controller that programmatically or by a signal from a control device (21, 22) performs voltage control at the terminals of the battery, voltage control at individual sections of the battery in the control-training cycle, control of the electrolyte temperature, control of the correct connection AB The controller is controlled via the RS-485 Modbus Rtu interface. Display panel 14 with information display: inclusion; charge; blocking; battery charge scale; Work; network connectivity; can be performed, for example, on LEDs.
Software-controlled measuring adapters 13 can be performed, for example, on a microprocessor PIK18F252, at the input of which an analog switch is installed, made, for example, on a field-effect transistor 2N7002LT1. In the shelving example, the adapter is made 4-channel.
In the claimed battery complex AB as a program-controlled power source 23 can be used a pulsed program-controlled power source for chargers AGRB 122.00.00.TU, manufactured by the company ZAO NPK VIL. The power source is an AC voltage to DC stabilized output converter, ranging from 0 to 20A, with voltage limitation. Input voltage 380 V, 50 Hz. The power source is configured to manually and automatically control the amount of stabilized output current in the desired range. In automatic mode, the power supply is controlled via the RS-485 Modbus Rtu interface.
The block of discharge resistors 24 is intended for the independent discharge of several batteries during the control and training cycle (KHZ). The discharge current (configuration of the resistor connection) is set by the system controller 21 based on the signal from the PC 22. The block of discharge resistors 24 has an input resistor selection circuit, for example, a majority element, which is controlled via the RS-485 Modbus Rtu interface.
The voltage sensors 17 are a wire ending with a contact element, for example, of the type "crocodile". In this case, the “crocodile” is connected to the controlled terminals of the AB or to the battery of the AB, and the second end of the wire is connected permanently to the adapter.
The temperature sensor 18 can be performed, for example, on the chip AD22100K1. At the output of the temperature sensor 18, the voltage is proportional to the temperature.
Automated software and hardware complex for charging and training batteries "Prism" works as follows. When the cover 9 of the rack is folded upwards, roll AB 5 into cell 2 along the live roll 5 until it stops 20. Then, using wires, for example, using the “crocodile” contacts, connect the AB terminals to contacts 3 to connect to the power source 23. In charge mode, voltage sensors 17 are connected to the output terminals AB 4, and in the control-training cycle mode - to one of the batteries AB 4. Turn on the exhaust ventilation 10, 11, 12. Cover 9 is closed.
Before connecting the battery 4 to the power source 23, the control device programmatically determines the type of the connected AB 4 (12V, 24V) from the database and gives a command to set the required charging current and duration of the charging time for the connected battery 4.
After connecting the power source 23, the adapter 13 monitors the status of the battery 4, displaying operational information on the display panel 14: inclusion; charge; discharge; blocking; battery charge scale; Work; the presence of communication over the charge / discharge control network. At the same time, all information, including information about the voltage on the battery 4 and the temperature of the electrolyte, from the output of the adapter through the interface 24 is fed to a software control device 21, 22, which programmatically monitors and controls the process of charging batteries 4.
In the process of charging the AB 4, the control device 21, 22, receiving real-time information from the measuring adapter 13, monitors the temperature of the electrolyte from the sensor 18 and the voltage at the terminals of the AB 4 from the sensor 18, which gradually increases during the charge and reaches the end of the charge norms. If the electrolyte temperature is higher than the permissible value, the control device 21, 22 disconnects the power supply 23 from this battery 4 for the time required for the electrolyte to cool down to a temperature of an acceptable value. After the electrolyte temperature returns to normal, the signal from the output of the adapter 13 controls the device 21, 22 again connects the power source 23 to this battery 4 and sets it to continue charging.
The charge of AB 4 continues until the voltage at the terminals of AB 4, which controls the sensor 17, and the density of the electrolyte (calculated by the control device programmatically) are constant for 1 hour while there is a lot of gas emission. After fulfilling this condition, the control device turns off the charged batteries 4. At the same time, the exhaust ventilation (duct 10 for connecting to the exhaust fan and curtains 11, 12) works continuously during the charging time of battery 4, removing from the electrolyte under the cover 9 and roller tables 5 gas and vapors.
When several simultaneous batteries of the same type 4 are charged at the same time after the end of the set charge time, the control device 21, 22 detects the lagging batteries 4 according to the information from adapter 13: voltage control at the battery terminals; battery level; the work is over.
Lagging AB 4 recharge for a given control time. Since the charged batteries are turned off, the recharge mode of the AB 4 is excluded.
If, at the end of the control time, the lagging AB 4 are not charged, they are subjected to a control and training cycle (CTC): a full charge of the AB (already completed), a control discharge with a given current for a predetermined time, determined by the type of battery, then the final full charge. At the same time, the control device programmatically determines the value of the bit resistance for this type of connected AB 4 and gives the command to the inputs of the block of 24 bit resistors. The block of bit resistors 24 contains n resistors, where n = 2, 3, ..., and is made with the possibility of their software connection in various configurations. As a result, an electrical connection of discharge resistances is formed, the cumulative value of which corresponds to the required nominal value.
The control device software determines the delivered capacity of the AB 4. If the AB 4, having not fulfilled the warranty period, gives less than 100% of the nominal capacity, then it is subjected to repeated KTZ. If AB 4, having not fulfilled the warranty period, at repeated KTZ gives less than 100% of the nominal capacity, then it is advertised.
At the end of the charge or the CTC, the control device 21, 22 turns off the power source 23. Information on the display panels 14 of the adapters 13: off; communication over the charge / discharge control network, absent.
Charged batteries 4 are removed from the rack in the reverse order: open the cover 9, disconnect from the power source, disconnect the voltage and temperature sensors of the electrolyte and roll out of cell 2 by rolling.
