Embodiment Construction

[0023] figure 1 Shows the hardware block diagram of the electrical system of the electric formula car, mainly including the drive system, battery and BMS management system, safety system and control and data acquisition system. The working principle of the electrical system of the vehicle is as follows: the main controller is the core of the vehicle , based on the CAN bus control method, to ensure real-time communication between the sensor and the main controller of the racing car, and the main controller is responsible for comprehensive coordination and control of the operating parameters of the electric racing car. The main switch of the safety system detects the switch state of the safety circuit, detects the current working state of the vehicle in real time, and the control and data acquisition system judges the current driving state of the car based on the collected signals of the wheel speed sensor, acceleration sensor, front ring instrument display control system, etc. ...

Abstract

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.

Description

technical field [0001] The invention relates to a pure electric formula racing car and belongs to the technical field of electric system control. Background technique [0002] The Chinese Student Formula Electric Competition (FSEC) is sponsored by the Society of Automotive Engineers of China. According to the standard, participating teams need to design and manufacture their own Formula E cars and participate in the competition within one year. [0003] The electric formula racing car has attracted more and more attention because of its excellent power, economy and environmental protection. The electrical control system of the electric racing car is quite different from the traditional fuel racing car. The electrical control strategy of the traditional fuel formula racing car has been Does not meet the requirements of Formula E racing. At present, electric control systems have been used in domestic pure electric formula racing cars, and the control strategies are mostly ba...
