Problems solved by technology

[0002] In the existing energy management system for general hybrid vehicles, the battery is used as one of the power sources. When the vehicle is just started in winter, the temperature of the battery pack is low. If the battery pack is directly used as the power source, the performance and service life of the battery pack will be reduced. The method of raising the temperature of the battery pack is generally to start the heater to heat up the battery pack. When the vehicle is parked and waits for the temperature of the battery pack to rise to its working temperature range, then start the motor to make the battery pack Work as a power source, which relatively increases the waiting time of passengers

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. This technical solution focuses on the entire vehicle, and conducts comprehensive heat management on the three modules of the battery pack, engine cooling system and air conditioning system, so that the power systems such as the engine and battery pack can work in the best condition. In this state, a relatively comfortable riding environment is provided for the passenger compartment. The thermal management system can realize comprehensive recycling of heat and heating under electric working conditions by controlling multiple control valves and multiple water pumps, which is energy-saving and environmentally friendly.

[0027] The vehicle energy management system of the first embodiment of the present invention is as follows: Figure 1-Figure 6 As shown, the vehicle energy management system includes a refrigerant circulation circuit 1 , an engine cooling and cabin heati...

Abstract

The invention relates to an automobile-used energy management system. The automobile-used energy management system comprises a refrigerant circulating loop, an engine heat dissipation and passenger cabin heating loop and a battery loop, wherein a second evaporator and a second heating heat exchanger are connected to a pipeline of the battery loop; the engine heat dissipation and passenger cabin heating loop is also connected with the second heating heat exchanger which is a double-flow heat exchanger and comprises a first flow channel and a second flow channel; and the battery loop and the engine heat dissipation and passenger cabin heating loop are respectively connected with one of the flow channels of the second heating heat exchanger, and the two flow channels can realize heat exchange. In this manner, heat of an engine can be transferred to a battery when an automobile is just started in cold winter, so that the battery can be used as power after achieving optimal temperature, and the service life of the battery is prolonged.
