A temperature control and energy-saving system and control method for an electric vehicle

Abstract

A temperature control and energy-saving system and control method for an electric vehicle, belonging to the field of automobiles, the electric vehicle temperature control and energy-saving system includes an air-conditioning system, a power battery and a motor assembly arranged in a power equipment cabin, and a power equipment cabin is also provided with a The first temperature control system for the working temperature of the power battery, the second temperature control system for controlling the working temperature of the motor assembly, and the control unit for controlling the operation of the first temperature control system, the second temperature control system and the air conditioning system, the first The temperature control system, the second temperature control system, and the air-conditioning system are connected in parallel through liquid pipelines. The beneficial effect of the present invention is that the electric vehicle temperature control and energy-saving system can simultaneously ensure that the power battery and the motor assembly are The normal working temperature can also control the appropriate temperature in the passenger compartment at the same time. The overall structure occupies a small space, realizes automatic energy-saving control, and improves the working life of various parts of the car and the comfort of the passengers.

Description

Technical field[0001]The present invention relates to the field of automobiles, and more particularly to an electric vehicle temperature control energy saving system and a control method.Background technique[0002]At present, the use area of ​​electric vehicles on the market is getting wider and wider, and the driving performance of electric vehicles requires increasingly high performance motors, electric control and battery systems will become the development trend of electric vehicles, while batteries, motors and electrical control systems. The efficiency and service life are very affected by temperature. There is often a high temperature alarm in high temperature regions, and there is no problem such as low temperature regions. Therefore, the cooling insulation system of automobiles is very important to electric vehicles. Since the current temperature control system includes independently set battery and motor temperature control system, the independent temperature control system ...

AI Technical Summary

Problems solved by technology

However, since the current temperature control system includes an independently set battery and motor temperature control system, the independent temperature control system requires more temperature control equipment, which not only takes up a lot of space, but also consumes a lot of energy, and the cost is relatively high.
