Embodiment Construction

[0013] See the attached picture. The present invention includes an electric drive system composed of a motor 1 and a plurality of lithium batteries 2. The positive and negative electrodes of each lithium battery 2 are connected to a voltage balance module 3, the lithium batteries 2 are connected in series, and the voltage balance modules 3 are connected in series. . Motor 1 is a brushless permanent magnet DC double stator disc motor. The driving technology of the electric vehicle of the present invention adopts a new type of DC permanent magnet brushless double stator motor, which is light in weight, only 10-17 kilograms, large torque, and strong overload capacity. Each lithium battery 2 of the lithium battery pack is connected to the balance line of a balancing module 3, which can realize the automatic voltage balance of the 2-5V, 200-400AH series lithium battery 1 and solves the problem of different internal resistances of the series battery during charging and discharging. ...

Abstract

The invention relates to a driving device of a pure electric vehicle. The driver comprises a motor and at least two lithium batteries; each lithium battery is connected with a voltage balancing module; the lithium batteries are connected in series respectively; the voltage balancing modules are connected together in series; and the motor is a brushless permanent-magnet DC dual-stator disk-type motor. The lithium batteries connected in series have balanced voltage, and the motor has large torque, small volume and light weight.

Description

Technical field [0001] The invention relates to a power system of an electric vehicle. [0002] Background technique [0003] At present, for the sake of the social environment and limited resources, the automobile industry is moving in the direction of the electric vehicle industry. Electric vehicles can effectively reduce energy consumption and basically achieve zero emissions and zero pollution. The core part of an electric vehicle is its power drive system, but the current electric vehicle lithium batteries are connected in series due to different resistances, which will cause voltage imbalance during charging and discharging. In order to meet the high load of the automobile, the electric motor of a motor vehicle must be equipped with a high-power electric motor, but the large-power electric motor has a relatively large volume and weight. [0004] Summary of the invention [0005] Aiming at the shortcomings of the prior art, the present invention designs and develops a seri...
