The requirement of lattice, beyond use condition by serious damage lithium ion battery, the failure that electrokinetic cell system causes will necessarily cause whole
The close concern of vehicle enterprise.Current driving force battery system relies primarily on battery management system（BMS）Carry out the output parameter of battery
Management.
In existing technology, different parameters is divided into different grades by BMS according to protection requirement, in the form of code,
Entire car controller and instrument display panel are sent to by communications protocol.Instrument display panel from cover to cover according to fault definition
The presentation of information that BMS is sent is come out.This simple processing mode brings many troubles to user and contact staff.
For example at the end of charging, battery has the ceiling voltage that monomer reaches charge protection, and after reaching this voltage, battery
Management system communicates with charger to be stopped charging and cutting off charge relay.But this information is the failure with highest level
Form offers instrument display panel and entire car controller.See the people of this display information, vehicle will be takeed for and gone out seriously
Failure, it is impossible to it uses, it is practical it is merely meant that charging complete.For another example battery temperature is excessively high can also perform protection, and similary information can be with
The failure mode of highest level is sent to entire car controller and instrument display panel.Driver sees the fault message of highest level,
People will be looked for repair, as long as actually parking take a momentary rest, battery temperature is reduced a bit, with regard to that can restore the function of normally travel.
This technology realizes display terminal by defining and coordinating the relevant electronic control unit of power battery communication system
" true " display avoids the fear of driver and passenger；It realizes " foolproof " output of customer service terminal, is grasped convenient for the classification of customer service
Make.
