Problems solved by technology

[0004] The present invention designs a thermal management system for a pure electric vehicle, which solves the technical problem that the current electric vehicle lacks a unified thermal management system for the entire vehicle, and the air conditioning system alone meets the heating and cooling requirements of the passenger compartment. The drive controller independently controls the cooling system, and the battery controller independently manages the battery system. Each system lacks a combined thermal management solution, with low efficiency and single function

Embodiment Construction

[0029] Combine below Figure 1 to Figure 6 , the present invention is further described:

[0030] Such as figure 1 As shown, a pure electric vehicle thermal management system is characterized in that it includes a motor system cooling circuit, a battery system low-temperature heat dissipation circuit, a battery system higher temperature cooling circuit, a battery system charging heating circuit, a passenger compartment heater heating circuit and Passenger compartment refrigeration circuit. The liquid storage pot 1, the motor radiator 2, the motor water pump 3 and the motor system 4 are connected through pipelines to form a motor system cooling circuit, and the motor system cooling circuit is cooled by the motor radiator coolant. The cooling fan assists the motor radiator 2 to dissipate heat. The battery radiator 5, the battery water pump 8, and the battery pack 9 are connected by pipelines to form a low-temperature heat dissipation circuit of the battery system. The pipelin...

Abstract

The invention relates to a thermal management system of a whole pure electric vehicle. The thermal management system of the whole pure electric vehicle is characterized in that the thermal management system of the whole pure electric vehicle comprises a motor system cooling circuit, a battery system low-temperature radiating circuit, a battery system high-temperature cooling circuit, a battery system charging and heating circuit, a passenger compartment heater heating circuit and a passenger compartment refrigerating circuit. The thermal management system of the whole pure electric vehicle has the advantages that cooling requirements of a motor system are effectively met, heating and cooling requirements of a battery system are effectively met, and refrigerating and heating requirements of a passenger compartment are effectively met.

Description

technical field [0001] The invention relates to a thermal management system, in particular to a complete vehicle thermal management system of a pure electric vehicle. Background technique [0002] As we all know, electric vehicles have become a hot spot in contemporary automotive research because of their advantages such as clean and pollution-free, high energy conversion efficiency, simple structure, and convenient use and maintenance. However, power batteries and other components have relatively high requirements on ambient temperature, resulting in a smaller geographical range for electric vehicles compared with traditional fuel vehicles, making it difficult to promote. [0003] Therefore, the research on how to cool the motor system, how to ensure that the battery system is in the optimal operating temperature range, and how to satisfy the cooling and heating of the passenger compartment is of great significance to the popularization of electric vehicles. Contents of t...
