Problems solved by technology

[0004] For battery packs without a communication interface, during the mass aging test process, the internal state data of the battery pack cannot be obtained in real time, so it is impossible to determine whether the aging process and aging results meet the design expectations
Since there is no communication interface, during mass aging tests, the aging test tool cannot be used after the aforementioned charger access detection, charger removal detection, overvoltage alarm, overvoltage alarm release, undervoltage alarm, and undervoltage alarm release are triggered. Get trigger information in real time

Embodiment Construction

[0026] The technical solutions protected by the present invention will be specifically described below in conjunction with the accompanying drawings.

[0027] The present invention proposes an aging test method and system for battery packs without communication interfaces. For battery packs without communication interfaces, especially new battery packs that have just been produced, the initial power of most new battery packs is about 50%. After the test, it can also be charged to the initial power through the charging device.

[0028] The system includes a host computer, a serial port conversion module, a discharge load and a charging device. The host computer is connected to the serial port conversion module through RS485 or CAN bus, and the charging device and the discharge load are connected to the discharge load manually or through a switch. The serial port conversion module is connected, and the host computer executes the aging test method of the present invention and dis...

Abstract

According to an aging test method and system for a battery pack without a communication interface provided by the invention, the output signals of a battery pack MCU and the charge and a discharge management unit are obtained through an output plug, and the aging test of the battery pack is realized by means of the aging test device; and internal key state data of charger access, charger removal, overvoltage alarm, overvoltage alarm release, undervoltage alarm, undervoltage alarm release and the like of a battery pack without a communication connector can be read in real time.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an aging test method and system for a battery pack without a communication interface. Background technique [0002] The battery packs on the market can be divided into two categories: those with communication interfaces and those without communication interfaces; for battery packs that do not require communication when used in the terminal, in order to reduce costs, some customers will request to cancel the communication interface. [0003] Regardless of whether it is equipped with a communication interface, in order to ensure safety, most battery packs will be equipped with safety functions, such as charger access detection, charger removal detection, overvoltage alarm, overvoltage alarm release, undervoltage alarm, undervoltage alarm release, etc. Function, in order to check whether the above functions are normal, it is necessary to do an aging test on the battery pack before...
