Abstract

The invention provides a vehicle auxiliary power supply method and system based on a super capacitor, and relates to the field of vehicle safety. According to the vehicle auxiliary power supply methodbased on the super capacitor, the voltage of a vehicle bus is detected after a trigger instruction used for waking up a controller is received, and when the voltage of the vehicle bus is lower than afirst preset voltage threshold value, a capacitor module is controlled to be connected with a storage battery of a vehicle in parallel, so that auxiliary power supply is conducted on the vehicle through the capacitor module. The capacitor module performs auxiliary power supply in a mode of being connected with the storage battery in parallel, so that the situation that vehicle equipment is damaged due to the fact that the voltage of a vehicle bus is too high can be avoided, and the safety of a vehicle can be guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a supercapacitor-based vehicle auxiliary power supply method and system. Background technique [0002] At this stage, most fuel vehicles are powered by lead-acid batteries. When the vehicle is started, the batteries are subjected to the impact of a large current of several hundred amperes, and the instantaneous voltage drop is large. It is also necessary to provide standby power after the generator stops working. The lead-acid battery The number of charging and discharging cycles is short, about 500 times, and the time to replenish electricity is long. Short-distance vehicles and vehicles with automatic start-stop functions will cause frequent insufficient charging, and frequent high-current discharges will accelerate the aging of the battery, resulting in battery failure. The service life of the battery cannot be predicted, and the replacement time cannot be determined, which will ...
