Electric Vehicle Battery Management System
Characteristics of Electric Vehicle Battery Management System:
Comprehensive protection: take multiple protection measures, achieve safety protection of the battery on over-voltage, under voltage, over current, the temperature is too high and the case of a collision .
Simple interface:It is simple and reliable when connecting inserter ,only output power line, communication lines, control lines .
Fault localization: fix the fault position and type accurately , reduce system maintenance time .
Data preservation: data recording and storing complete, reliable, with the data black box function, data storage encryption and image backup ?
