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.
