Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0022] Such as figure 1 As shown, the four-wheel-drive hybrid power system with supercapacitor in the present invention includes a four-wheel-drive transmission system driven by an engine unit and a rear-drive transmission system auxiliary-driven by an electric motor. The four-wheel drive transmission system can adopt the structural form in the prior art. In order to make up for the disadvantages of using batteries in the prior art, a supercapacitor unit is also provided in the present invention, that is, the rear drive transmission system includes a motor drive unit and a supporting The supercapacitor unit is set; when the vehicle accelerates or climbs, the supercapacitor unit discharges to provide assistance to the motor drive unit, that is, the supercapacitor unit is used ...

Abstract

The invention discloses a four-wheel drive hybrid power system with a super capacitor. The four-wheel drive hybrid power system includes a four-wheel drive system driven by an engine unit and a rear drive transmission system auxiliary driven by a motor, and the rear drive transmission system includes a motor drive unit and an associated super capacitor unit; when a vehicle accelerates or climbs, the super capacitor unit discharges to provide power to the motor drive unit; and when the vehicle slows down or goes downhill, the super capacitor unit is charged by the motor drive unit. According tothe four-wheel drive hybrid power system with the super capacitor, a storage battery pack used in the prior art is replaced with the super capacitor unit, so that the vehicle can be operated normallyin a low temperature environment; and meanwhile, the discharge capability of a large current is greater after using the super capacitor unit, the energy conversion efficiency is higher, the energy loss in the energy conversion process is smaller, and the acceleration and climbing ability of the vehicle are greatly improved.

Description

technical field [0001] The invention relates to an automobile four-wheel-drive hybrid power system, in particular to a four-wheel-drive hybrid power system with a supercapacitor. Background technique [0002] For the drive systems of hybrid electric vehicles widely used at present, an engine drive unit and an electric-assisted drive unit are provided, and the two work together to realize the driving of the hybrid electric vehicle. [0003] When a hybrid vehicle accelerates or climbs a slope, it requires the electric auxiliary drive unit to discharge a large current. High rate fast charge and fast discharge characteristics and a long service life. However, currently used battery-based electric auxiliary drive units are less and less suitable for current needs due to the low power density of batteries, low charge and discharge efficiency, and high current charge and discharge will greatly shorten their lifespan. Contents of the invention [0004] Aiming at the disadvantage...
