Embodiment Construction

[0026] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0027] Pure electric car system is to adopt AC permanent magnet synchronous motor (PMSM) in the present embodiment, and it mainly provides four kinds of functions:

[0028] 1. Normal torque drive;

[0029] 2. Traveling at low speed;

[0030] 3. Regenerative braking energy recovery;

[0031] 4. Provide drive power.

[0032] The realization of these functions is realized through the control module of the motor. In this pure electric car system, the motor has the following six operating modes, and the control conversion between these six modes is realized through the instructions of the vehicle controller.

[0033] (1) prohibited

[0034] (2) Zero torque

[0035] (3) speed

[0036] (4) Torque

[0037] (5) failure

[0038] (6) Alarm

[0039] Among them, zero torque, speed, torque a...

Abstract

The present invention relates to a power system for simple electric vehicle and operational method thereof, including an AC permanent magnet synchronous machine (PMSM) and a motor control system, wherein the motor control system employs a digital signal processing (DSP) chip; the power system is controlled to switch among six modes of a inhibited mode, a zero torque mode, a speed mode, a torque mode, a alarm mode and a fault mode through a entire-car controller.

Description

technical field [0001] The invention relates to a power system of a car, in particular to a power system of a pure electric vehicle and an operation method thereof. Background technique [0002] At present, people pay more and more attention to the protection of the environment and the effective and rational use of energy. Therefore, pure electric vehicles with high efficiency, energy saving and environmental protection have become one of the development trends of the automobile industry. The pure electric drive system can achieve the purpose of low energy consumption and zero emission, and has great market prospects. When used in cars, due to the limitation of installation space, the volume and size of the motor drive system are strictly required. However, in the existing technology, the control and protection of the electric drive system cannot be realized, so that the electric drive system of pure electric cars cannot be guaranteed. Normal and reliable operation, while ...
