Embodiment Construction

[0017] Attached below figure 1 Specific embodiments of the present invention will be further described.

[0018] see figure 1 The refrigerant circulation system is composed of electric compressor 1, condenser 2, pressure switch 21, integrated electromagnetic switch expansion valve 4, evaporator 5, water cooler 19 and expansion valve 23, electric compressor 1, condenser assembly 2, The pressure switch 21, the integrated electromagnetic switch expansion valve 4 and the evaporator 5 are circularly connected, and the expansion valve 23 and the water cooler 19 are tapped in the pipelines at both ends of the integrated electromagnetic switch expansion valve 4 and the evaporator 5. An electromagnetic fan 3 is installed behind the condenser 2, and the electromagnetic fan 3 is controlled by a PWM signal to generate different air volumes to help the condenser dissipate heat. When the vehicle needs cooling, the electric compressor 1 starts, and the high-temperature and high-pressure re...

Abstract

The invention provides a control system for heat management of an electric vehicle. The control system is characterized in that the system comprises a refrigerant circulating system, a coolant circulating system and a battery pack temperature control system, wherein the refrigerant circulating system is communicated with the battery pack temperature control system via a water cooler, and the coolant circulating system is communicated with the battery pack temperature control system via a three-way water valve, so the three systems form an intercommunicating and circulating control system to control the temperature in the carriage and the working temperature of the electrical devices of the battery pack. The control system has the following positive effects: effective heat management can be carried out on each part of the electric vehicle; the problem of heating difficulty of the electric vehicle is solved by adopting the residual heat of the electrical devices in an economical and energy-saving manner; preheating and cooling of the power battery of the electric vehicle are well controlled; and the working temperature of the battery and electrical devices of the electric vehicle can be controlled, thus realizing complete heat system management of the electric vehicle.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a thermal management control system for a complete electric vehicle. Background technique [0002] At present, due to the government's emphasis on energy conservation and environmental protection, more and more automobile manufacturers have begun to enter the field of hybrid electric vehicles and pure electric vehicles. Electric vehicles have entered a period of rapid development and will become a new force in the automobile market in the future. Since the electric vehicle cancels the fuel engine and adds some high-power electronic equipment, the thermal management system of the electric vehicle has undergone tremendous changes compared with the traditional fuel vehicle: [0003] First, the heating method in the compartment has changed. In traditional vehicles, the waste heat of the engine coolant is used to heat the compartment. Electric vehicles do not have engines, so new heat...
