Integrated structure of vehicle-mounted charger and motor controller of electric automobile

Abstract

The invention provides an integrated structure of a vehicle-mounted charger and a motor controller of an electric automobile and belongs to the field of an electric automobile control technology. The structure comprises a vehicle-mounted charger and motor controller integrated module and a cooling pipeline. The vehicle-mounted charger and motor controller integrated module is used for carrying out integrated circuit design on a charger module and a motor controller module which are separated previously; the charger module and the motor controller module share a power switching device and a communication control module. The cooling pipeline is used for carrying out water cooling on the vehicle-mounted charger and motor controller integrated module. According to the integrated structure, an integrated circuit of the vehicle-mounted charger module and the motor controller module is designed into one integrated module, so that the structure is safe and reliable and easy to control; the requirements on charging a high-voltage power battery in the automobile and controlling a motor are met and the whole automobile space structure of the electric automobile is greatly saved, so that the integrated structure has a very good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle control, and in particular relates to an integrated structure of an electric vehicle on-board charger and a motor controller. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have incomparable advantages such as environmental protection, energy saving and low noise. Under the background of energy crisis and environmental pollution, electric vehicles have become a research hotspot in all countries in the world, and they are the next round of automobile industry revolution. It is of great significance to vigorously develop electric vehicles for my country to occupy a place in the future automobile industry. [0003] At present, the popularity of electric vehicles is still very low, there are many design defects in various aspects, and the standards are not uniform. The charging devices introduced by some manufacturers are expensive and inefficient. In...
