A working method of electric vehicle control system

Abstract

A working method of an electric vehicle control system, the control system includes a manifold, a compressor, a condenser, a spare cylinder, a filter, a solenoid valve, an evaporator, and a dryer; wherein the cooling method and the heating method are as follows: the compressor The gaseous Freon is compressed, and then sent to the condenser to dissipate heat and become a liquid Freon at room temperature and high pressure. The heat of heat dissipation heats the nearby air to form a heat medium; the liquid Freon is filtered through a filter, passes through a solenoid valve, and enters an evaporator, making liquid Freon Gasification, thereby absorbing a large amount of heat, cooling the nearby air to form a refrigerant; the gaseous Freon re-enters the compressor after being dried by the dryer, and fans are installed on the condenser and the evaporator to blow the refrigerant or heat medium to the Manifold.

Description

technical field [0001] The invention relates to the related fields of new energy vehicles, in particular to a working method of an electric vehicle control system. Background technique [0002] With the development of science and technology, the pressure of hydraulic and pneumatic systems is getting higher and higher, and the degree of automation is also getting higher and higher. Fluid systems are used in aerospace, ships, high-pressure air source vehicles, construction machinery and other fields. As a common technical demand of people, new energy vehicles have increasingly appeared in our lives, and they play an important role in protecting the environment and non-renewable resources. [0003] Among the new energy vehicles, electric vehicles are one of the major categories. Hybrid or pure electric vehicles have become more popular. Among them, the battery pack of electric vehicles is the core and the most important component of electric vehicles. [0004] In actual use, t...

AI Technical Summary

Problems solved by technology

[0005] 1. The temperature control system and its battery pack in the prior art lack reliable, perfect and complete temperature control technology

[0006] 2. In the control system and its battery pack of the prior art, part of the temperature control technology has been designed, but the functional components are independent and scattered, occupying a large volume

[0007] 3. Manifold technology already exists in the existing technology, but it cannot be reasonably applied to the battery pack system of new energy vehicles

[0008] 4. The battery pack of the existing technology has the problem of high power consumption. One of the most important parameters of new energy electric vehicles is the battery life. The power consumption directly determines the grade of the car, but the system inevitably uses a large number of electromagnetic valve, power consumption

[0009] 5. The battery pack in the prior art lacks perfect emergency treatment methods such as when the battery pack burns or bursts. The existing processing methods are complex and the processing system occupies a large volume

[0010] 6. Although the solenoid valve in the prior art has a spring auxiliary drive, additional spring support such as a spring support is required, and at the same time, guide parts are also provided for the armature, which greatly increases the number of parts

[0011] 7. Solenoid valves in the prior art, especially multi-way valves, need to specialize in the production of multi-way switching parts, which increases the number of parts and costs, and lacks pressure relief capability

[0012] 8. The temperature control system in the prior art lacks perfect and complete supporting parts
