Abstract

The present disclosure relates to a battery management system and an electric vehicle, which can not only reduce the volume of the battery management system, but also reduce the cost of the entire vehicle. A battery management system, the battery management system BMS includes a BMS main control module and an analog front-end module, wherein the BMS main control module includes a first bridge chip and a main control chip, and the analog front-end module is used to detect the power battery. The single battery information is transmitted to the main control chip through the first bridge 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, to a battery management system and an electric vehicle. Background technique [0002] The Battery Management System (BMS) is used to monitor and safely 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 a single battery, a microcontroller that processes the information collected by the sampling module, and a power conversion module that supplies power to the microcontroller. It communicates with the BMS main control module through the CAN bus. This makes the battery management system expensive and bulky. SUMMARY 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 reduce the volume of t...
