Abstract

The invention relates to a battery management system and an electric vehicle, and aims to reduce the size of the battery management system and reduce the cost of the whole vehicle. The battery management system (BMS) comprises a BMS main control module and an analog front-end module, the BMS main control module comprises a first bridging chip and a main control chip. The analog front-end module isused for detecting single battery information of a power battery and transmitting the single battery information to the main control chip through the first bridging chip, and the main control chip monitors the power battery based on the single battery information.

Description

technical field [0001] The present disclosure relates to the field of electric vehicles, and in particular, relates to a battery management system and the electric vehicle. Background technique [0002] The Battery Management System (BMS) is used to monitor and control the reliable operation of the power battery. The existing BMS includes an analog front-end module and a BMS main control module. The analog front-end module includes a sampling module that collects the voltage and temperature of the single battery, a microcontroller that processes the information collected by the sampling module, and a power conversion module that supplies power to the microcontroller, and the microcontroller Communicate with the BMS main control module through the CAN bus. This makes the battery management system costly and bulky. Contents of the invention [0003] The purpose of the present disclosure is to provide a battery management system and an electric vehicle, which can not only ...
