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. ...

The present invention proposes a pure electric formula racing vehicle electrical system, with a main controller as the core, data transmission based on the CAN bus, the electrical system includes a drive system, a battery and a BMS management system, a safety system, and a control and data acquisition system. The drive system is driven by dual rear-wheel motors; the battery and BMS management system detects signals such as battery current, voltage, and temperature in real time, dynamically formulates battery management strategies, and controls battery work through thermal management, active balance management, charge management, and discharge management. Under suitable working conditions; the safety system detects the status of the racing car in real time, and cuts off all power sources if the status is abnormal; the control and data acquisition system combines the pedal angle sensor and other signals to obtain the driving intention of the racing car, and finally realizes the power system, high-voltage safety, and hardware of the racing car. Controls such as early warning and protection solve the problems of complex wiring harness layout of electric racing cars, weak anti-interference ability of CAN signals, and poor robustness of electrical systems.
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...
