Abstract

The invention discloses a whole-vehicle thermal management system of a new energy vehicle, and belongs to the technical field of vehicles. The whole-vehicle thermal management system comprises a powermotor thermal management loop, which comprises a first water pump, a charger, a direct current transformer, a power motor inverter, a power motor body and a first radiator which can be communicated in sequence; a power battery thermal management loop, which comprises a second water pump, a third radiator, a second radiator and a power battery which can be communicated in sequence; a passenger compartment heat management loop, which comprises a passenger compartment heating loop that comprises a third water pump, a third radiator, a fourth radiator and an electric heating device which can be communicated in sequence; a first two-way valve, a first four-way valve, and a second four-way valve. Waste heat of a power motor can be used for heating a power battery and a passenger compartment, and the endurance mileage of the power battery is increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a thermal management system for a complete vehicle of a new energy automobile. Background technique [0002] With the continuous development of new energy technologies, new energy vehicles are becoming more and more popular in the market. [0003] Generally, new energy vehicles are equipped with power batteries to provide driving force for new energy vehicles. Limited by the energy density of the power battery, its cruising range is short. And the power battery is greatly affected by temperature. In the low temperature environment in winter, the temperature of the power battery is low and the performance is limited, which leads to a significant reduction in the cruising range of the power battery. And in the low temperature environment in winter, the driver also needs to turn on the air conditioner to heat the passenger compartment, which shortens the cruising range of the...
