Abstract

The present invention discloses an energy device employing an aluminum air battery and a supercapacitor for a vehicle. The energy device comprises the aluminum air battery for discharging, and the supercapacitor capable of charging and discharging. The aluminum air battery and the supercapacitor are connected to a bidirectional DC / DC converter, and the bidirectional DC / DC converter is connected to a motor controller for controlling the rotational speed of a drive motor of the vehicle. The energy device also comprises a vehicle controller for controlling the bidirectional DC / DC converter to perform voltage matching and / or charging or discharging of the supercapacitor. The present invention discloses a control method of the energy device employing the aluminum air battery and the supercapacitor. The present invention discloses the vehicle comprising the energy device. The energy device solves the problem of low efficiency in rapid acceleration and low-speed running, and the supercapacitor can be charged by using the electric energy generated by the aluminum air battery or the recycled electric energy, to prevent the phenomena of overcharge and overdischarge of the supercapacitor, and protect the aluminum air battery and the supercapacitor set.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an energy device of an aluminum-air battery and a supercapacitor. The invention also relates to a control method of the energy device of the aluminum-air battery and the supercapacitor. In addition, the invention also relates to a vehicle with the energy device. Background technique [0002] At present, most of the cars on the road use gasoline or diesel fuel extracted from crude oil. Compared with internal combustion vehicles powered by fossil energy, electric vehicles have significant advantages in environmental protection and energy saving. [0003] At present, most electric vehicles use lithium batteries as energy storage power sources. Lithium batteries have high energy density and can meet the requirements of vehicle cruising range, but the charging and discharging current is too small to release large power, especially in braking. link, the effect of regenerative energ...
