Selecting any coolant refill module allows for refilling of the entire thermal management system, improving coolant refill efficiency and enhancing maintenance convenience.

[0071] Figure 3 FIG. 1 shows a flow chart of a vehicle thermal management control method according to an embodiment. Figure 3 As shown, a vehicle thermal management control method is provided, which is applied to Figure 1 Taking the control module in FIG. 1 as an example, the method may include the following steps:

[0072] Step 301, obtaining the vehicle's operating mode or coolant filling mode;

[0073] Step 302 : Control whether the first four-way valve, the second four-way valve, the third four-way valve, the fourth four-way valve, and the fifth four-way valve are opened according to the working mode or the coolant filling mode.

[0074] In some embodiments, when the working mode is engine start in the engine circuit and warm-up is required, it is determined whether the first coolant temperature in the intercooler circuit is higher than the second coolant temperature in the engine circuit; when the first coolant temperature is higher than the second coolant temperature, the second four-way valve is opened, and the first four-way valve, the third four-way valve, the fourth four-way valve and the fifth four-way valve are closed.

[0075] It's understood that when the engine is started and needs to be warmed up, if the temperature of the first coolant in the intercooler circuit is higher than the temperature of the second coolant in the engine circuit, the excess heat in the intercooler circuit can be used to warm up the engine. In this implementation, by opening the second four-way valve, the higher-temperature coolant in the intercooler circuit flows into the engine circuit, achieving rapid engine warm-up.

[0076] In some embodiments, when the working mode is electric drive mode and the battery in the battery circuit needs to be heated, the fourth four-way valve is controlled to open, and the first four-way valve, the second four-way valve, the third four-way valve and the fifth four-way valve are closed.

[0077] It is understood that in electric drive mode, if the battery needs to be heated and the electric drive circuit has waste heat that can be utilized, the waste heat of the electric drive circuit can be used to heat the battery. In this implementation, by opening the fourth four-way valve, the higher temperature coolant in the electric drive circuit flows to the battery circuit, thereby achieving battery heating.

[0078] In some embodiments, when the working mode is the engine drive mode, and a heating command is received, and the third coolant temperature in the engine circuit reaches a preset temperature, the first four-way valve is controlled to open, and the second four-way valve, the third four-way valve, the fourth four-way valve and the fifth four-way valve are controlled to close.

[0079] It is understood that in engine mode, if a user-initiated heating command is received and the third coolant temperature is higher than the coolant temperature in the heater circuit, the heater circuit can utilize waste heat from the engine circuit, saving energy for the heating device. In this implementation, by opening the first four-way valve, the higher-temperature coolant in the engine circuit flows to the heater circuit, providing heat for the heater circuit.

[0080] In some embodiments, when the working mode is the charging mode, the fifth four-way valve is controlled to open, and the first four-way valve, the second four-way valve, the third four-way valve and the fourth four-way valve are controlled to close; when the working mode is the hybrid mode, the third four-way valve and the fourth four-way valve are controlled to open, and the first four-way valve and the fifth four-way valve are controlled to close.

[0081] Understandably, in charging mode, the entire thermal management system has no waste heat. Opening the fifth four-way valve heats the coolant via the heating device, and the heated coolant then enters the battery circuit through the fifth four-way valve to heat the battery circuit. In hybrid mode, opening the third and fourth four-way valves utilizes waste heat from the intercooler and electric drive circuits to heat the battery circuit. Opening the second, third, and fourth four-way valves utilizes waste heat from the engine, intercooler, and electric drive circuits to heat the battery circuit.

[0082] Of course, in other demand combination modes, forward or reverse heat exchange and energy replenishment can be achieved between all circuits according to actual working conditions, and according to the amount of energy required, one or more circuits can be enabled at the same time to exchange heat and energy for a certain circuit.

[0083] In some embodiments, when the coolant filling mode is full-circuit filling, four of the first four-way valve, the second four-way valve, the third four-way valve, the fourth four-way valve and the fifth four-way valve are controlled to be open, and one four-way valve is closed.

[0084] It can be understood that the coolant filling mode can be divided into full-circuit filling and custom filling.

[0085] When filling the entire circuit, it is necessary to open N-1 four-way valves (N is the total number of four-way valves) to achieve a large series connection of all circuits. At this time, the entire thermal management system can be replenished at any filling port. When filling the entire circuit, the electronic water pump corresponding to the opened four-way valve can also be set to run at a preset duty cycle and running time. During the implementation process, when the user selects full circuit filling, the control module can open the first four-way valve, the second four-way valve, the third four-way valve, and the fourth four-way valve to control the first electronic water pump, the second electronic water pump, the third electronic water pump, and the fourth electronic water pump to run at a 25% duty cycle for 6 minutes. After the operation is completed, the next cycle can be executed as needed.

[0086] During custom refilling, users can select the four-way valves to open and set the corresponding electronic water pumps to operate at a preset duty cycle and duration. In implementation, after the user selects the first and second four-way valves to open, the control module opens the first and second four-way valves and controls the first and second electronic water pumps to operate at a 25% duty cycle for six minutes. After the operation is completed, the next cycle can be performed as needed.

[0087] By controlling the four-way valve, this method enables multiple combinations, allowing for controlled regulation of heat levels across the engine module, intercooler module, electric drive module, battery module, and heater module, reducing vehicle energy consumption and increasing range. Furthermore, by controlling the opening of the four-way valve, the engine module, intercooler module, electric drive module, battery module, and heater module can be connected in series. Selecting any coolant refill module allows for refilling of the entire thermal management system, improving coolant refill efficiency and enhancing maintenance convenience.

[0088] The following describes an embodiment of the device of the present application, which can be used to implement the vehicle thermal management control method described in the above embodiments of the present application.

[0090] In some embodiments, the four-way valve control module 402 is also used to determine whether the first coolant temperature in the intercooler circuit is higher than the second coolant temperature in the engine circuit when the working mode is engine start-up in the engine circuit and warm-up is required; when the first coolant temperature is higher than the second coolant temperature, the second four-way valve is opened and the first four-way valve, the third four-way valve, the fourth four-way valve and the fifth four-way valve are closed.

[0091] In some embodiments, the four-way valve control module 402 is also used to control the fourth four-way valve to open and the first four-way valve, the second four-way valve, the third four-way valve and the fifth four-way valve to close when the working mode is the electric drive mode and the battery in the battery circuit needs to be heated.
