Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

The Programmable Power Supply (PPS) belongs to a Power Supply type supported in the USB PD3.0, and is a Power Supply capable of realizing voltage and current regulation by using USB PD protocol output. PPS draws the scheme of the current market rapid charging, and integrates the scheme into a set of large and complete rapid charging scheme again so as to realize the rapid charging protocol which can be compatible with mainstream, such as QC4.0, QC3.0, SCP, FCP, PE3.0, PE2.0, VOOC and the like.

The PPS protocol can realize the regulation of voltage and current, and can be directly connected with a battery for charging without adding an additional Charger module circuit, and the PPS Charger can realize the highest output voltage of 20V and supports the highest 5A current direct charging for the battery, thereby improving the charging efficiency and reducing the charging time.

At present, the mainstream fast Charger in the market is still based on a Charger charging scheme, namely voltage and current regulation during fast charging is realized by using a Changer module circuit. For example, the charger outputs a constant voltage, the Changer module circuit can regulate the voltage and the current and then charge the battery, and the charger is not dependent on whether being provided with a voltage and current regulating function circuit. However, the charge module circuit itself has efficiency loss, which causes a large amount of heat generation, thereby limiting the charging power to be further increased. Meanwhile, the larger the charging power is, the more excellent performance of the components is required to support, and meanwhile, the occupied area of the components is increased, so that the miniaturization design of the product is influenced.

By using the fast charging scheme of the PPS protocol, a charge module circuit can be omitted, the occupied area of components can be reduced to the maximum extent, and the charging power can be maximized. However, the charging can be completed only by using the corresponding PPS charger, and since the charging interface of the ordinary charger (non-PPS charger) is the same as that of the PPS charger, for example, the charging interface may be a Type-C interface, for example, if the battery only supports the charging of the ordinary fast charger, if the PPS charger is accessed at this time, the accessed charger cannot charge the battery, thereby causing confusion to the user and further reducing the user experience.

Therefore, the embodiment of the application provides a charging control circuit, a charging control method, a charging control device, a battery and a movable platform, wherein the charging control circuit can select a charging circuit matched with the charging type to charge according to the type of a charger, so that the problems are solved, and the user experience is improved.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic circuit structure diagram of a charge control circuit according to an embodiment of the present disclosure. The charging control circuit 100 comprises a main control circuit 11, a charging interface circuit 12 and at least two charging circuits 13, wherein the charging interface circuit 12 is used for connecting a charger, and the charging circuits 13 are connected with a battery and used for charging the battery through the charger.

The main control circuit 11 includes a Micro Control Unit (MCU), wherein the charging interface circuit 12 and the charging circuit 13 are both directly or indirectly connected to the MCU, and the MCU can acquire corresponding information of the charger through the charging interface circuit 12 and perform corresponding control according to the acquired information. For example, the type of the accessed charger is acquired, and one of the charging circuits is controlled to be opened according to the acquired type of the charger to charge the battery.

The charging interface circuit 12 is capable of accessing different types of chargers. The interface of the charging interface circuit 12 may be, for example, a Type-C interface, but may also be a Type-a interface, a USB interface, or the like. Correspondingly, the interfaces of the chargers of different types can also be, for example, Type-C interfaces, and certainly, can also be Type-a interfaces and USB interfaces.

Illustratively, the different types of chargers include PPS type chargers and non-PPS type chargers. The non-PPS type charger can comprise a fast charger or a slow charger, and the fast charger can be divided into fast chargers such as QC4.0, SCP, FCP, PE3.0 and VOOC according to the used fast charging protocol.

At least two charging circuits 13, each charging circuit 13 for connection between the charging interface circuit 12 and the battery. Wherein different charging circuits are used to adapt different types of chargers.

Illustratively, as shown in fig. 2, the at least two charging circuits include a first charging circuit and a second charging circuit, wherein the first charging circuit is compatible with the PPS charger and the second charging circuit is compatible with the non-PPS charger.

Specifically, the first charging circuit includes a charging switch 131, and a control terminal of the charging switch 131 is connected to the main control circuit 11; and/or the second charging circuit comprises a charge module circuit 132, and the charge module circuit 132 is connected with the main control circuit 11. So that the main control circuit 11 selects the corresponding charging circuit to charge the battery.

In some embodiments, the charge module circuitry 132 includes an internal MOS switch integrated in the charge module or an external MOS switch disposed outside the charge module. The internal MOS switch is selected, so that the space of the charge module can be saved, but the charging power is limited, and the external MOS switch is selected, so that the charge module occupies a large space, but the charging power is large. Therefore, in practical design, flexible selection and design can be performed according to the requirements of charging power and occupied area.

It is understood that, if the non-PPS charger corresponds to the slow charger, the second charging circuit may or may not include the Changer module circuit.

When a charger is connected to the charging interface circuit 12, for example, when a user inserts the charger and intends to charge a battery, the main control circuit 11 is configured to identify the type of the connected charger and select a charging circuit adapted to the type of the charger to charge the battery.

For example, when the main control circuit 11 recognizes that the type of the connected charger is a PPS charger, the first charging circuit is controlled to charge the battery, and specifically, the charging switch 131 may be controlled to be turned on, so as to connect the charger and the battery, thereby charging the battery.

The type of charger may be identified by the communication protocol employed by the charger, such as by PPS protocol identifying whether the charger is a PPS charger or a non-PPS charger. Or, whether the charger is a fast charger or a slow charger is identified according to the fast charging protocol.

Specifically, the charging switch 131 may include a switching tube, such as a MOS tube, a gate of the MOS tube is connected to the main control circuit 11, and the main control circuit 11 sends a high level to the MOS tube to control the MOS tube to be turned on, so as to implement that the PPS charger charges the battery.

Illustratively, the second charging circuit is controlled to charge the battery, for example, when the main control circuit 11 recognizes that the type of the charger is a non-PPS charger. Specifically, the enable signal is sent to enable the charge module circuit to charge the battery.

In some embodiments, since the non-PPS charger may be a fast charger or a slow charger, when the main control circuit 11 recognizes that the type of the charger is the non-PPS charger, it may also determine whether the charger is a fast charger; and adjusting the output voltage of the Charger according to the determination result to meet the input voltage of the Charger module circuit 132, and enabling the Charger module circuit 132 to charge the battery.

Specifically, if the determination result is that the Charger is fast charging, a voltage regulation instruction is sent to the Charger to enable the Charger to regulate the output voltage until the output voltage reaches the input voltage of the Charger module circuit 132; and if the determination result is that the charger is not a quick-charging charger, not sending a voltage regulation instruction to the charger, and using the default output voltage of the charger, for example, charging by adopting the default output voltage of 5.0V.

In some embodiments, the charge module circuit is enabled to charge the battery, specifically, the output voltage and the output current of the charge module circuit 132 are adjusted, the battery is charged with a constant current, and the battery is charged with a constant voltage when the battery voltage reaches a slow charging voltage. Thereby improving the charging efficiency of the battery.

The charging control circuit provided by the embodiment of the application can realize that the corresponding charging circuit is selected to charge the battery according to the type of the charger, for example, the PPS charger is inserted, and then the charging circuit corresponding to the PPS charger is selected to charge the battery, so that the situation that the battery cannot be charged due to different types of the accessed chargers is avoided, and the user experience is further improved.

In some embodiments, in order to provide reliability and safety of battery charging, before identifying the type of the charger, the main control circuit 11 may further obtain a battery parameter of the battery, determine whether the battery parameter meets a charging requirement, if it is determined that the battery parameter meets the charging requirement, perform the step of identifying the type of the charger, and select a charging circuit adapted to the type to charge the battery according to the identified type of the charger. Since the battery is charged immediately after the charging circuit adapted to the type of the charger is determined, there is a safety risk that the safety and reliability of the battery charging can be improved by selecting the adapted charging circuit.

In the embodiment of the present application, the battery parameters at least include the battery voltage and the battery temperature, and of course, the acquired battery parameters may also include other information, such as the battery capacity, the battery type, and the like.

In some embodiments, when determining whether the battery parameter meets the charging requirement, the main control circuit 11 may specifically determine whether the battery voltage is within a preset voltage range, and whether the battery temperature is within a preset temperature range; and if the battery voltage is within the preset voltage range and the battery temperature is within the preset temperature range, determining that the charging requirement is met.

Illustratively, in the embodiment of the present application, the preset voltage range may be, for example, (2.5V to 4.4V), the preset temperature range may be, for example, (0 ° to 45 °), and when the battery voltage is within (2.5V to 4.4V) and the battery temperature is within (0 ° to 45 °), it is determined that the charging requirement is satisfied. It is understood that the preset voltage range and the preset temperature range may have other range values.

In other embodiments, when determining whether the battery parameter meets the charging requirement, the main control circuit 11 may specifically determine whether the battery voltage is greater than a preset voltage, and whether the battery temperature is lower than a preset temperature; and if the battery voltage is greater than the preset voltage and the battery temperature is lower than the preset temperature, determining that the charging requirement is met.

Illustratively, the preset voltage is 2.5V and the preset temperature is 45 °. And when the battery voltage is more than 2.5V and the battery temperature is lower than 45 degrees, determining that the charging requirement is met. It is understood that the preset voltage and the preset temperature may have other values.

In some embodiments, as shown in fig. 3, the charging control circuit 100 includes a fast charging protocol circuit 14, and the fast charging protocol circuit 14 is respectively connected to the charging interface circuit 12 and the main control circuit 11, that is, connected between the charging interface circuit 12 and the main control circuit 11, and is configured to communicate with an accessed charger handshake to obtain the type of the charger. Specifically, the fast charging protocol circuit 14 includes a PD protocol chip for communicating with an accessed charger handshake to obtain the type of the charger, such as whether the accessed charger is a PPS charger.

In some embodiments, as shown in fig. 4, to power the master control circuit 11, the charge control circuit 100 includes a voltage conversion circuit 15. Specifically, the voltage conversion circuit 15 is connected to the charging interface circuit 12 and the main control circuit 11, that is, the voltage input end of the voltage conversion circuit 15 is connected to the charging interface circuit 12, and the output end is connected to the main control circuit 11, so as to convert the charger output voltage accessed by the charging interface circuit 12 into the working voltage of the main control circuit 11, so as to provide the working voltage for the main control circuit 11.

In some embodiments, as shown in fig. 4, to power the fast charge protocol circuit 14, the charge control circuit 100 includes a voltage conversion circuit 15. Specifically, the voltage conversion circuit 15 is connected to the charging interface circuit 12 and the fast charging protocol circuit 14, that is, the voltage input end of the voltage conversion circuit 15 is connected to the charging interface circuit 12, and the output end of the voltage conversion circuit is connected to the fast charging protocol circuit 14, so as to convert the charger output voltage accessed by the charging interface circuit 12 into the working voltage of the fast charging protocol circuit 14, so as to provide the working voltage for the fast charging protocol circuit 14.

In some embodiments, as shown in fig. 5, in order to supply power to the main control circuit 11, the charging control circuit 100 includes a voltage conversion circuit 15, and the voltage conversion circuit 15 is connected to the battery and the main control circuit 11, and is configured to convert an output voltage of the battery to provide an operating voltage to the main control circuit 11.

In some embodiments, as shown in fig. 5, in order to supply power to the fast charge protocol circuit 14, the charge control circuit 100 includes a voltage conversion circuit 15, and the voltage conversion circuit 15 is connected to the battery and the fast charge protocol circuit 14, and is configured to convert the output voltage of the battery to provide an operating voltage for the fast charge protocol circuit 14.

In some embodiments, if the output voltage of the charger is greater than the operating voltage of the main control circuit and the operating voltage of the fast charge protocol circuit, or the output voltage of the battery is greater than the operating voltage of the main control circuit and the operating voltage of the fast charge protocol circuit, the voltage conversion circuit 15 is specifically configured as a voltage reduction circuit.

In this embodiment, the working voltages of the main control circuit 11 and the fast charging protocol circuit 14 are respectively the working voltages of the micro control unit and the PD protocol chip, and in this embodiment, the working voltage of the micro control unit is equal to the working voltage of the PD protocol chip, for example, 3.5V, but may also be unequal.

Illustratively, the output voltage of the charger is 5V, and the working voltage of the micro control unit and the working voltage of the PD protocol chip are both 3.3V, then the voltage conversion circuit 15 is specifically a voltage reduction circuit, specifically a circuit for converting 5.0V into 3.3V.

It can be understood that a plurality of voltage conversion circuits 15 may be used to charge the main control circuit 11 and the fast charge protocol circuit 14, and specifically, one voltage conversion circuit 15 may supply power to the main control circuit 11, and another voltage conversion circuit 15 may supply power to the fast charge protocol circuit 14. Of course, the plurality of voltage conversion circuits 15 may form a series connection mode to respectively supply power to the main control circuit 11 and the fast charge protocol circuit 14, and is particularly suitable for the case that the working voltages of the main control circuit 11 and the fast charge protocol circuit 14 are not equal.

In some embodiments, in order to improve the safety of battery charging, the main control circuit 11 may further specifically obtain a battery voltage of the battery, adjust the starting voltage of the charger according to the battery voltage of the battery through the PD protocol chip, and control the first charging circuit to charge the battery according to the adjusted starting voltage. Wherein the starting voltage is greater than the battery voltage.

Specifically, if the main control circuit 11 detects that the accessed charger is a PPS charger, the main control circuit 11 communicates with the charger through a PD protocol chip according to the battery voltage of the battery, so as to adjust the starting voltage of the charger, and after the starting voltage is adjusted, the charging switch 131 of the first charging circuit is turned on to charge the battery.

For example, the battery voltage of the battery is determined to be 12V, the output voltage of the charger may be adjusted to 12.1V, and then the charging switch 131 in the first charging circuit is controlled to be closed, so as to charge the battery. The output voltage of the charger is adjusted to 12.1V, and specifically, the voltage can be adjusted to 12.1V step by step.

In some embodiments, the main control circuit 11 is configured to obtain a charging voltage in the first charging circuit, and obtain a battery voltage of the battery; and adjusting the output voltage and the output current of the charger according to the charging voltage and the battery voltage to charge the battery.

For example, the output voltage and the output current of the charger are adjusted to charge the battery, and specifically, the output voltage and the output current of the charger are adjusted to perform constant current charging on the battery, and then perform constant voltage charging on the battery when the battery voltage reaches a slow charging voltage. The charging efficiency of the battery can be improved by performing constant-current charging and then performing constant-voltage charging.

Specifically, the main control circuit 11 continuously adjusts the output voltage and current of the charger according to the charging voltage and the battery voltage through the PD protocol chip to maintain the constant current charging of the battery, and when the battery voltage reaches the full charging voltage, the charging voltage is maintained unchanged, and the battery enters the constant voltage charging stage until the battery is fully charged.

The main control circuit 11 communicates with the PPS charger through the PD protocol chip to determine the charging voltage and the charging current, but if the PPS charger output voltage (charging voltage) is lower than the battery voltage, the battery current may flow back to the PPS charger, i.e. a current backflow phenomenon occurs.

In some embodiments, in order to solve the problem of the current backflow phenomenon to improve the charging safety, as shown in fig. 6, the charging control circuit 100 includes a backflow prevention circuit 16, and the backflow prevention circuit 16 is connected in parallel with the charging switch 131 for controlling the charging switch 131 to be turned on or off according to the voltage magnitude at two ends of the charging switch 131.

In the embodiment of the present application, the backflow prevention circuit 16 includes an ORing controller, and backflow prevention is implemented by the ORing controller, but in other embodiments, other electronic components may be used, for example, an ideal diode or the like is used to implement the backflow prevention circuit.

Specifically, for example, when it is detected that the terminal voltage of the first end of the charging switch 131 is smaller than the terminal voltage of the second end, or the terminal voltage of the first end is smaller than the terminal voltage of the second end and exceeds a preset threshold, a trigger signal is sent to the main control circuit 11, and the main control circuit 11 sends a closing signal to the charging switch 131 to turn off the charging switch 131, so as to implement the anti-backflow, where the closing signal may be, for example, a low-level signal.

The first terminal of the charge switch 131 is connected to the charge interface circuit, and the second terminal of the charge switch 131 is connected to the battery.

At present, PPS chargers manufacturers are more in the market, but the PPS chargers have different quality, although the PPS chargers can be charged by the current regulated by the main control circuit, the PPS chargers all have average current meeting the requirement, and the peak value of the PPS charger is very large due to oscillation of the PPS charger charging current. For example, the average charging current is 5A, but the peak value of the charging current is higher than 5A, and the maximum peak value may reach 7.5A, which may exceed the maximum allowable charging current of the battery, thereby causing damage to the battery cell and affecting the life and safety of the battery.

In some embodiments, in order to solve the problem of oscillation of the charging current to improve the life and safety of the battery, as shown in fig. 7, the charging control circuit 100 includes a current detection circuit 17, and the current detection circuit 17 is connected to the first charging circuit and connected to the main control circuit 11, and is configured to detect the charging current of the first charging circuit and send the charging current to the main control circuit 11, so that the main control circuit 11 controls the charging switch 131 to be turned on or off according to the oscillation of the charging current. In the embodiment of the present application, the current detection circuit 17 may include a current amplifier, but may be implemented by other circuits.

Specifically, when the main control circuit 11 determines that the amplitude of the detected charging current exceeds a preset threshold, which indicates that the maximum tolerable charging current of the battery has been exceeded, the main control circuit sends a shutdown signal to the charging switch 131 to turn off the charging switch 131, so as to prevent damage caused by current oscillation, thereby improving the service life and safety of the battery.

Referring to fig. 8, fig. 8 is a schematic flowchart of a charging control method provided in an embodiment of the present application, where the method may be applied to a main control circuit in a charging control circuit provided in any one of the embodiments of the present application, and by executing the charging control method, charging can be implemented for different types of chargers, so that user experience is improved.

As shown in fig. 8, the charge control method includes step S101 and step S102.

S101, identifying the type of the charger;

and S102, selecting a charging circuit matched with the type of the charger to charge the battery.

In embodiments of the present application, the different types of chargers include PPS chargers and non-PSS chargers, where the non-PPS chargers in turn include fast chargers and slow chargers. Other types of chargers, or different types of battery divisions, may of course be included.

The PPS charger and the non-PPS charger, or the fast charger and the slow charger included by the non-PPS charger can be identified through a communication protocol adopted by the charger, for example, the PPS charger or the non-PPS charger is identified through a PPS protocol, and the fast charger or the slow charger is identified according to a fast charging protocol.

Illustratively, the at least two charging circuits of the charging control circuit specifically include a first charging circuit and a second charging circuit, wherein the first charging circuit is adapted to the PPS charger, and the second charging circuit is adapted to the non-PPS charger.

Correspondingly, a charging circuit matched with the type of the charger is selected to charge the battery, specifically: when the type of the charger is identified to be a PPS charger, controlling the first charging circuit to charge the battery; and when the type of the charger is identified to be a non-PPS charger, controlling the second charging circuit to charge the battery. Therefore, the charging of the battery can be realized by accessing different types of chargers.

In some embodiments, when the type of the Charger is identified as a non-PPS Charger, it may be further determined whether the Charger is a fast charging Charger, and the output voltage of the Charger is adjusted according to the determination result to meet the input voltage of the Charger module circuit, and the Charger module circuit is enabled to charge the battery.

Specifically, if the determination result is that the Charger is fast-charging, a voltage regulation instruction is sent to the Charger to enable the Charger to regulate the output voltage until the output voltage reaches the input voltage of the Charger module circuit, and if the determination result is that the Charger is not fast-charging, the voltage regulation instruction is not sent to the Charger, and the default output voltage of the Charger is used.

Illustratively, the input voltage of the charge module circuit at the time of fast charging is 9V, 12V or 15V, and the like, and the default output voltage is 5V, for example. During charging, the output voltage of the Charger needs to be adjusted to meet the input voltage requirement of the charge module circuit, for example, 9V.

In order to improve the charging efficiency of the battery, the charge module circuit is enabled to charge the battery, specifically, the output voltage and the output current of the charge module circuit can be adjusted, the battery is charged with a constant current, and when the voltage of the battery reaches a slow charging voltage, the battery is charged with a constant voltage.

In some embodiments, the charge control circuit includes a fast charge protocol circuit that includes a PD protocol chip. In order to improve the charging safety and the charging efficiency, when the charger is identified as a PPS charger, before the first charging circuit is controlled to charge the battery, the initial voltage of the charger can be adjusted through the PD protocol chip according to the battery voltage of the battery; and controlling the first charging circuit to charge the battery according to the adjusted initial voltage. Wherein the starting voltage is greater than the battery voltage.
