Analysis on the Influence of Battery Management System CAN Message Asynchronous for PHEV Control Strategy and Safety Performance

Abstract

Abstract: In order to solve the influence of vehicle control strategy and safety performance for battery management system controller area network(CAN) message asynchronous, the source of CAN signal inconsistency is analyzed and plug-in hybrid electric vehicle(PHEV) simulation model is build. Battery management system CAN message asynchronous is analyzed and modified by theory method. Battery management system(BMS) is designed based on theory analysis result and dynamic monitor and management power(DMMP) method is applied in state of charge(SOC) modify calculation procedure in order to improve accuracy. The influence of vehicle control strategy and safety performance can be limited and accepted. The simulated and test result are shown as vehicle control strategy and safety performance can’t be affected hardly by vehicle control strategy and safety performance after improved design method is used.

Key words: plug-in hybrid electric vehicle(PHEV);battery management system(BMS);message asynchronous;control strategy;safety performance
