The Real-Time LCD System for the Pure Electric Vehicle Based on the CAN Bus

With the rapid development of automobile instrument technology, the traditional combined instrument has many limitations on the display. A real-time LCD system for the pure electric vehicle based on the CAN bus is proposed in the paper. The system network hierarchy architecture was analyzed and the system hardware architecture, information exchange protocol and system LCD interface were designed in detail. It realized collection and monitoring for the multi-source information of the vehicle and battery. The actual road tests show that the system is effective, real time, easy installation, and low cost.
