Title:
BATTERY DETECTION METHOD AND DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/050389
Kind Code:
A1
Abstract:
The present application provides a battery detection method and device, and a readable storage medium. The battery detection device comprises: a voltage measurement module, which is used for connecting to a battery to be detected, and measuring an open circuit voltage of the battery; a processor, which is connected to the voltage measurement module and is used for obtaining the open circuit voltage; a constant voltage source, which is connected to the processor and is used for inputting a test voltage into the battery under the control of the processor after the battery is left for a preset amount of time, the test voltage being the same as the open circuit voltage; and a current measurement module, which is connected to the battery and is used for measuring an instantaneous current of the battery after the test voltage is inputted, wherein the processor is further connected to the current measurement module and is used for obtaining the instantaneous current, and the self-discharge characteristic of the battery is determined according to the instantaneous current and a preset current threshold. The detection device is used to reduce detection costs of a battery, improve the detection efficiency of a battery, and improve the applicability of battery detection.
