Embodiment

[0039] Such as figure 1 As shown, a power plant for an electric vehicle is composed of two relatively independent power sources.

[0040] The main power source includes an electric motor 1, an electric motor controller 2, a pedal 3 and a battery pack 5, the battery pack 5 provides power to the electric motor 1 through the electric motor controller 2, and the electric motor controller 2 controls the electric motor 1, the pedal 3 provides an operating signal to the electric motor controller 2, and a main power switch 4 is set between the battery pack 5 and the electric motor 1 as required. The battery pack 5 can be, but is not limited to, a storage battery pack that can be repeatedly charged and discharged.

[0041] Auxiliary power source A, which includes a current sensor 6, an air source switch electromagnetic valve 12, an air motor 13, an air source switch electromagnetic valve controller 15, and an air storage device. The air storage device provides pressure to the air moto...

Abstract

The invention relates to a power device of an electric automobile. The device adopts a hybrid power mode. The technical scheme employed by the invention is that the power device of the electric automobile comprises an electric motor (1), a pedal (3) and a battery pack (5), wherein the power output end of the electric motor (1) is fixedly connected with a shaft (17); an electric motor controller (2) controls the operation of the electric motor (1). The power device is also provided with a current sensor (6), an air source switch solenoid valve (12), a pneumatic motor (13), an air source switch solenoid valve controller (15) and an air storage device; the power output end of the pneumatic motor (13) is fixedly connected with the shaft (17); and the air source switch solenoid valve controller (15) controls the air source switch solenoid valve (12). After the technical scheme is adopted, extra power is supplied by pressured air, and compressed air-electricity hybrid power drive is realized.

Description

technical field [0001] The invention relates to a power device of an electric vehicle. The device adopts a hybrid power mode, which can effectively improve the power transmission effect of the electric vehicle, and is suitable for driving the electric vehicle. Background technique [0002] With the rapid development of the automobile industry, the depletion of the earth's oil resources is becoming more and more serious, the exhaust emissions of automobiles are becoming more and more serious, and the smog weather is becoming more and more serious and covers people's lives. Human beings continue to propose low-carbon, environmental protection, Call for green travel. [0003] In this context, all kinds of new energy vehicles are also emerging, such as pure electric vehicles. The battery used in pure electric vehicles is a major technical bottleneck, and the safety and consistency of lithium-ion power batteries are one of the difficulties. The theoretical charging and dischar...
