Problems solved by technology
[0004] The detection of the existing new energy insulation resistance is basically detected by the battery management system BMS. The battery management system BMS reports the insulation resistance and insulation fault to the vehicle VCU, and the vehicle controller VCU handles the insulation fault. It takes a long time to report high-voltage faults. , the problem that high voltage fault handling cannot be dealt with in time

The invention discloses a safety control system and method for an insulation module of a new energy vehicle. The system includes: an insulation detection module IM, and the insulation detection module IM communicates with a vehicle controller VCU, a PTC controller, and a charger controller OBC through a CAN line. , Oil pump controller SPC, motor controller MCU communication connection, insulation detection module IM and main negative relay, PTC relay, SPC relay, OBC relay, heating relay and pre-charge relay communication connection. The insulation detection module IM conducts high-voltage safety detection based on the insulation resistance detection mechanism, relay adhesion and high-voltage component failure, improves the safety verification mechanism of high-voltage components, reduces the risk of high-voltage electric shock in the operation of vehicle electrical equipment, and detects the occurrence of faults in real time. By disconnecting the relays, each high-voltage electrical equipment is protected in time, and the safety of high-voltage electrical equipment is increased.
Description
Technical field [0001] The present invention belongs to the field of new energy vehicles, and more particularly, the present invention relates to a safety control system and method for a new energy vehicle insulation module. Background technique [0002] National standard stipulates that the operating voltage of the electric vehicle high pressure system is greater than 30V and is less than or equal to 1000V, and the DC is greater than 60V and less than or equal to 1500V. From the national standard, it can be seen that the working voltage of the new energy vehicle high pressure system is higher than the safety voltage range of the human body. Different from traditional fuel vehicles, new energy vehicles use insulation safety detection modules high-pressure insulation to detect and use relays to safely control other high pressure components. [0003] New energy vehicles can realize remote PTC heating, remote charging control, etc., but to perform safety detection, high-voltage powe...
