A thermal management system for a range-extended hybrid electric vehicle

Abstract

The invention provides a thermal management system of an extended-range hybrid electric vehicle, which belongs to the technical field of thermal management. It solves the problems of poor thermal adaptability and high energy consumption of existing vehicles. In this thermal management system, the passenger compartment cooling circuit is formed between the compressor, the mode switching module, the first heat exchanger and the second heat exchanger, and the cooling circuit between the compressor, the mode switching module, the first heat exchanger and the heat exchange integration module The battery cooling circuit is formed between the compressor, the third heat exchanger, the mode switching module and the first heat exchanger to form the passenger compartment heating circuit 1, and the passenger compartment heating circuit 2 is formed between the range extender and the fourth heat exchanger A battery heating circuit 1 is formed between the compressor, the heat exchange integration module, the mode switching module and the first heat exchanger, and a battery heating circuit 2 is formed between the range extender and the heat exchange integration module. This system improves the thermal comfort of the passenger compartment and the performance of battery charging and discharging, and prolongs the service life of the battery.

Description

technical field [0001] The invention belongs to the technical field of heat management, and relates to a heat management system of a range-extended hybrid electric vehicle. Background technique [0002] With the urgency and harshness of national environmental protection requirements, automobile fuel consumption is also increasingly strictly controlled in regulations. In order to achieve this goal, domestic automobile companies of all sizes have begun to develop new energy vehicles. Compared with traditional fossil energy vehicles, electric vehicles have many advantages such as high torque at low speed, low noise, and low pollution. However, since the energy density of power battery modules is often lower than necessary, it is difficult for electric vehicles to match traditional fuel vehicles in terms of cruising range. In order to improve the cruising range of electric vehicles, extended-range hybrid vehicles came out. An on-board generator set composed of "internal combust...
