Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a battery control method, apparatus, device, and medium. Background Technology

[0002] Electric bicycles, electric motorcycles, and other electric devices typically incorporate multiple batteries. These batteries constitute the device's battery system. The positive terminals of each battery are connected in parallel to the positive terminal of the electric device, and the negative terminals are connected in parallel to the negative terminal, thus achieving parallel connection of the batteries within the device. Each battery can be equipped with a unique corresponding Battery Management System (BMS), a discharge switch, and a charging switch. The BMS controls the on / off state of the battery's discharge and charging switches.

[0003] In related technologies, a common battery control scheme involves setting up a host computer within the electric device to control all the batteries in the device. Based on preset discharge and charging conditions, the host computer instructs each battery management system to turn its discharge and charging switches on or off, thereby switching the discharge and charging states of each battery. This battery control scheme requires an additional host computer to control all the batteries in the electric device, increasing hardware costs, and individual batteries cannot autonomously switch between discharge and charging states. Summary of the Invention

[0004] This invention provides a battery control method, apparatus, device, and medium to solve the problems in related technologies where battery control schemes require an additional host to control all batteries in an electric device, increasing hardware costs and preventing individual batteries from autonomously switching between discharge and charging states.

[0005] According to one aspect of the present invention, a battery control method is provided, applied in a battery management system of a battery, comprising:

[0006] The current battery information of the battery and other batteries is acquired periodically through a state machine. Based on the current battery information of the battery and other batteries, the current charge and discharge state numerical sequence of the battery system is determined.

[0007] The current battery information includes: the current battery enable variable, the current discharge switch state value, and the current charging switch state value.

[0008] The state machine determines the next charge / discharge state value sequence corresponding to the current charge / discharge state value sequence. Based on the state value corresponding to the battery in the next charge / discharge state value sequence, it instructs the battery's discharge switch and charging switch to be turned on or off.

[0009] According to another aspect of the present invention, a battery control device is provided, configured in a battery management system of a battery, comprising:

[0010] The numerical sequence determination module is used to periodically acquire the current battery information of the battery and other batteries through a state machine, and determine the current charge and discharge state numerical sequence of the battery system based on the current battery information of the battery and other batteries.

[0011] The current battery information includes: the current battery enable variable, the current discharge switch state value, and the current charging switch state value.

[0012] The switch indicator module is used to determine the next charge / discharge state value sequence corresponding to the current charge / discharge state value sequence through the state machine, and to indicate whether the discharge switch and the charging switch of the battery are turned on or off according to the state value corresponding to the battery in the next charge / discharge state value sequence.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0014] At least one processor;

[0015] and a memory that is in communication with the at least one processor network;

[0016] The memory stores a computer program that can be executed by the at least one processor, which is then executed by the at least one processor to enable the at least one processor to perform the battery control method according to any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the battery control method according to any embodiment of the present invention.

[0018] The technical solution of this invention uses a state machine in the battery management system to periodically acquire the current battery enable variables, current discharge switch state values, and current charging switch state values ​​of the battery and other batteries. Based on these values, the current charge / discharge state value sequence of the battery system is determined. Then, the state machine determines the next charge / discharge state value sequence corresponding to the current sequence. Based on the state value corresponding to the battery in the next sequence, the discharge and charging switches of the battery are instructed to be turned on or off. This solves the problem that related battery control schemes require an additional control unit for all batteries in the electric device. The use of a host computer to control the battery increases hardware costs and addresses the issue that individual batteries cannot autonomously switch between discharge and charge states. This paper addresses this problem by employing a state machine from a battery management system. This machine automatically determines the sequence of values ​​representing the discharge and charge states of each battery in the system at the next moment, based on the battery enable variables, discharge switch state values, and charge switch state values ​​at the current moment. It then automatically instructs the battery's discharge and charge switches to turn on or off according to the corresponding state values ​​in the sequence. This allows the batteries to autonomously switch between discharge and charge states based on the system's overall charging and discharging status, eliminating the need for a separate host computer to control all batteries in the electric device.

When the battery discharge switch is turned on, the battery starts its discharge function and can discharge to power electric devices. When the battery discharge switch is turned off, the battery stops its discharge function, stops discharging to external devices, and does not supply power to electric devices. For example, the battery discharge switch is a field-effect transistor connected to the battery used to start or stop the battery's discharge function.

[0068] Optionally, the target candidate charge / discharge state value sequence is the same as the current charge / discharge state value sequence. The target candidate charge / discharge state value sequence is the same as the current charge / discharge state value sequence. Therefore, the next charge / discharge state value sequence corresponding to the target candidate charge / discharge state value sequence is the next charge / discharge state value sequence corresponding to the current charge / discharge state value sequence.

[0069] Optionally, instructing the discharge switch and charging switch of the battery to be turned on or off based on the state value corresponding to the battery in the next charge / discharge state value sequence includes: performing the following operations through the state machine: if the battery is a currently disabled battery in the battery system, then extracting the state values ​​of the discharge switch and charging switch of the disabled battery in the next charge / discharge state value sequence; instructing the discharge switch of the battery to be turned off based on the state value of the discharge switch of the disabled battery; and instructing the charging switch of the battery to be turned off based on the state value of the charging switch of the disabled battery.

[0070] Optionally, the discharge switch state value of the unenabled battery in the next charge / discharge state value sequence is a state value used to characterize the discharge state that the unenabled battery in the battery system needs to be in at the next moment after the current moment.

[0071] Optionally, based on the state value of the discharge switch transistor of the disabled battery, instructing the battery's discharge switch transistor to be turned off includes: if the current state value of the discharge switch transistor of the disabled battery is 10, instructing the battery's discharge switch transistor to be turned off. If the current state value of the discharge switch transistor of the disabled battery is 10, indicating that the disabled batteries in the battery system need to disable their discharge function at the next time after the current time, that is, the discharge switch transistors of all disabled batteries in the battery system need to be turned off, then instructing the battery's discharge switch transistor to be turned off.

[0072] Optionally, instructing the battery's discharge switch to turn off includes: performing the following operation through the state machine: sending a turn-off signal to the control terminal of the battery's discharge switch to instruct the battery's discharge switch to turn off.

The state machine can also instruct the battery's discharge and charging switches to be turned on by sending an on signal to the control terminals of the battery's discharge and charging switches. A shutdown signal indicates that the switches are turned off. An on signal indicates that the switches are turned on. Instructing the battery's discharge switch to be on means instructing the battery to start its discharge function. Instructing the battery's discharge switch to be off means instructing the battery to stop its discharge function. Instructing the battery's charging switch to be on means instructing the battery to start its charging function.

[0084] The technical solution of this invention uses a state machine in the battery management system to periodically acquire the current battery enable variables, current discharge switch state values, and current charging switch state values ​​of the battery and other batteries. Based on these values, the current charge / discharge state value sequence of the battery system is determined. Then, the state machine determines the next charge / discharge state value sequence corresponding to the current sequence. Based on the state value corresponding to the battery in the next sequence, the discharge and charging switches of the battery are instructed to be turned on or off. This solves the problem that related battery control schemes require an additional control unit for all batteries in the electric device. The use of a host computer to control the battery increases hardware costs and addresses the issue that individual batteries cannot autonomously switch between discharge and charge states. This paper addresses this problem by employing a state machine from a battery management system. This machine automatically determines the sequence of values ​​representing the discharge and charge states of each battery in the system at the next moment, based on the battery enable variables, discharge switch state values, and charge switch state values ​​at the current moment. It then automatically instructs the battery's discharge and charge switches to turn on or off according to the corresponding state values ​​in the sequence. This allows the batteries to autonomously switch between discharge and charge states based on the system's overall charging and discharging status, eliminating the need for a separate host computer to control all batteries in the electric device.

It can also automatically instruct the discharge switch and charge switch of the battery to be turned on or off according to the state value corresponding to the battery in the numerical sequence, thereby realizing the battery's autonomous switching between discharge and charge states according to the charge / discharge state of the battery system.
