Electric vehicle temperature control energy saving system and control method

Abstract

The invention discloses an electric vehicle temperature control energy saving system and a control method, and belongs to the field of vehicles. The electric vehicle temperature control energy savingsystem includes an air conditioning system, a power battery and a motor assembly, wherein the power battery and the motor assembly are arranged in a power equipment cabin, the power equipment cabin isfurther internally provided with a first temperature control system for controlling the operating temperature of the power battery, a second temperature control system for controlling the operating temperature of the motor assembly, and a control unit for controlling the work of the first temperature control system, the second temperature control system and the air conditioning system, and the first temperature control system, the second temperature control system and the air conditioning system are connected in parallel through fluid path pipelines. The electric vehicle temperature control energy saving system and the control method have the beneficial effects that the electric vehicle temperature control energy saving system can ensure the normal operating temperature of the power battery and the motor assembly at the same time by using a set of temperature control equipment, and can further control the appropriate temperature in a passenger cabin, the occupied area of the whole structure is small, automatic energy saving control is realized, and the service life of all parts in a vehicle is prolonged and riding comfort of passengers is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an electric vehicle temperature control and energy-saving system and control method. Background technique [0002] At present, the use area of ​​electric vehicles in the market is becoming wider and wider, and the driving performance requirements of electric vehicles are getting higher and higher. High-performance motors, electronic control and battery systems will become the development trend of electric vehicles, while batteries, motors and electronic control systems The efficiency and service life of electric vehicles are greatly affected by temperature. High temperature alarms often occur in high temperature areas, and problems such as failure to start in low temperature areas are becoming more and more obvious. Therefore, the cooling and heat preservation system of automobiles is very important for electric vehicles. However, since the current temperature control system includes i...

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.
