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 heat management system can control multiple control valves and multiple water pumps to realize comprehensive heat recycling and heating under electric working conditions, 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 heating circuit...

Abstract

An energy management system for a vehicle, comprising a refrigerant circulation circuit, an engine heat dissipation and cabin heating circuit, and a battery circuit; the pipeline of the battery circuit is connected with a second evaporator and a second heating heat exchanger; the engine heat dissipation and cabin heating The heat circuit is also connected to the second heating heat exchanger. The second heating heat exchanger is a double-channel heat exchanger, which includes a first flow channel and a second flow channel. The battery circuit is connected to the engine cooling circuit and the cabin heating circuit. One channel of the secondary heat exchanger, heat exchange can be performed between the two channels; in this way, the engine heat can be transferred to the battery when the car is just started in cold winter, so that the battery can be used as power after reaching an appropriate temperature , to improve battery life.

Description

technical field [0001] The invention relates to the technical field of vehicle energy, in particular to an energy management system and control method for a hybrid electric vehicle. Background technique [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. Contents of the invention [0003] The purpose of the present invention...
