Abstract

The invention belongs to the technical field of drive control over hybrid power vehicles, and particularly relates to a hybrid power source for hybrid power. According to the technical scheme, when a vehicle accelerates urgently, the high instantaneous power is provided according to the advantage that the specific power of a supercapacitor is high, the response characteristic of the hybrid power source can be improved, the magnitude of discharging currents of a battery can be reduced, and damage to the battery is reduced; when the deceleration of the vehicle is high, and the high braking power is needed, most of braking energy is absorbed through the supercapacitor, and the magnitude of charging currents for the battery is reduced; the recovery ratio of the braking energy can be increased, and the service life of the battery can be prolonged.

Description

technical field

[0001] The invention belongs to the technical field of drive control of hybrid vehicles, and in particular relates to a composite power supply for hybrid vehicles. Background technique

[0002] Traditional armored vehicles use diesel engines as power, which can meet most of the needs of armored vehicles. However, armored vehicles entering air-raid shelters and other poorly ventilated areas require vehicles to achieve zero emissions, so as to prevent the huge emissions and low emission quality of armored vehicles from affecting air quality and causing CO poisoning. Moreover, sometimes armored vehicles have a high demand for stealth. The use of pure electric driving for armored vehicles can greatly reduce the infrared and noise radiation of the vehicle, which is conducive to avoiding infrared detection and noise search. All of these have raised the demand for the use of electric drive for armored vehicles. However, in view of the low energy storage density of...
