The invention provides a whole-car electrical system for a pure electric formula racing car. The system takes a main controller as a core, performs data transmission based on a CAN bus, and comprisesa driving system, a battery and BMS management system, a safety system and a control and data acquisition system. The driving system is driven by rear wheels and double motors; the battery and BMS management system detects signals of current, voltage, temperature and the like of the battery in real time, dynamically formulates a battery management strategy, and controls the battery to work under aproper working condition by means of thermal management, active equalization management, charging management, discharging management and the like. The safety system detects the state of the racing car in real time, and cuts off all power sources if the state is abnormal; the control and data acquisition system obtains the driving intention of the racing car by combining signals such as a pedal angle sensor and the like, finally realizes the control of a power system, high-voltage safety, hardware early warning protection and the like of the racing car, and solves the problems of complex wiring harness arrangement of the electric racing car, weak CAN signal anti-interference capability, poor robustness of an electrical system and the like.

    本发明提出一种纯电动方程式赛车整车电气系统,以主控制器为核心,基于CAN总线进行数据传输,电气系统包括驱动系统、电池及BMS管理系统、安全系统和控制及数据采集系统。驱动系统采用后轮双电机驱动;电池及BMS管理系统实时检测电池的电流、电压、温度等信号,动态制定电池管理策略,通过热管理、主动均衡管理、充电管理、放电管理等手段控制电池工作在合适工况;安全系统实时检测赛车状态,若状态异常则切断所有动力来源;控制及数据采集系统结合踏板角度传感器等信号得到赛车行驶意图,最终实现赛车的动力系统、高压电安全、硬件预警保护等控制,解决了电动赛车线束布置复杂、CAN信号抗干扰能力弱、电气系统的鲁棒性差等问题。
