Problems solved by technology

Soft-pack batteries have the advantages of light weight, large capacity, small internal resistance, high safety performance, and flexible design. Like ordinary batteries, soft-pack batteries will also experience abnormal conditions such as failure and overcharging, which will cause the battery module to fail to work normally. Thereby reducing the safety performance of electric vehicles

Abstract

The invention relates to the field of safety detection of power supply devices, in particular to a battery module and a battery management system. The battery module comprises a plurality of submodules, wherein each submodule comprises a fixing component and two soft pack batteries mounted on the fixing component; a pressure detecting component is arranged between the two soft pack batteries; andthe pressure detecting component is used for transmitting detected pressure values between the two soft pack batteries to a controller connected with the pressure detecting component, and the controller generates an alarm signal and sends out the alarm signal when a pressure value greater than a preset pressure threshold exists in the received pressure values. The battery management system comprises a processor and the battery module, wherein the processor is in communication with the pressure detecting component of the battery module. Through the battery module and the battery management system, provided by the embodiment of the invention, timely detection of abnormal conditions of the soft pack batteries can be achieved, so that timely replacement of the soft pack batteries under the abnormal conditions is facilitated, and thus an electric automobile has high safety performance.

Description

technical field [0001] The invention relates to the field of safety detection of power supply devices, in particular to a battery module and a battery management system. Background technique [0002] Batteries are the energy core of electric vehicles and provide power for electric vehicles to run, including soft pack batteries, which refer to batteries whose shells are made of soft packaging materials (for example, aluminum-plastic composite film). Soft-pack batteries have the advantages of light weight, large capacity, small internal resistance, high safety performance, and flexible design. Like ordinary batteries, soft-pack batteries will also experience abnormal conditions such as failure and overcharging, which will cause the battery module to fail to work normally. Thereby reducing the safety performance of electric vehicles. Therefore, how to timely detect whether the pouch battery is abnormal and replace the abnormal pouch battery in a timely manner, so as to ensure ...
