[0039] Figure 1A block diagram of a heat exchange system 100 for an electric vehicle with dual electronic controls according to an embodiment of the present disclosure is shown. The dual electronic controls in the heat exchange system 100 include a drive motor and a generator controller. The heat exchange system 100 may include:

[0040] Vehicle expansion tank 101, used for storing water;

[0041] Water pump 102 is connected to the vehicle-mounted expansion tank and is used to transport the water flowing out of the vehicle-mounted expansion tank;

[0042] Two three-way valves 103 are respectively connected to the outlet and inlet of the water pump;

[0043] The water circuit 104 of the drive motor and the water circuit 105 of the generator controller are connected in series and then connected between the two three-way valves.

[0044] The generator controller can be a GCU (Generator Control Unit), IGBT (Insulated Gate Bipolar Transistor), or SIC (Motor Controller) structure.

[0045] By adding two three-way valves 103 to the heat exchange system, and then connecting the water circuit 104 of the drive motor and the water circuit 105 of the generator controller in series between the two three-way valves 103, the opening direction of the two three-way valves can be flexibly adjusted according to the heat exchange requirements. This allows for intelligent control of the heat exchange priority of the drive motor and the generator controller, meeting different heat exchange priority requirements, minimizing water pump energy consumption, and improving heat exchange efficiency. In this way, the performance output of the dual-electric control system can be maximized, avoiding any impact on vehicle performance, and enabling the dual-electric control electric vehicle to effectively perform heat exchange.

[0046] like Figure 2 As shown, in one embodiment, one end of the water circuit of the drive motor is connected in series with the first outlet of the first three-way valve of the two three-way valves. Figure 2 The three-way valve 103 located at the inlet of the water pump 102 (port 2) and the first inlet of the second three-way valve ( Figure 2 The other end of the three-way valve connected to the radiator 107 has its port 2 connected in series with the water circuit of the generator controller;

[0047] One end of the water circuit of the generator controller is connected in series with the second outlet of the first three-way valve of the two three-way valves. Figure 2 The three-way valve 103 located at the inlet of the water pump 102 (port 3) and the second inlet of the second three-way valve ( Figure 2The three-way valve (port 3) connected to the radiator 107 is connected in series with the water passage of the drive motor at the other end.

[0048] One end of the water circuit of the drive motor is connected in series with the first outlet of the first three-way valve and the first inlet of the second three-way valve. The other end is connected in series with the water circuit of the generator controller. One end of the water circuit of the generator controller is connected in series with the second outlet of the first three-way valve and the second inlet of the second three-way valve. The other end is connected in series with the water circuit of the drive motor. In this way, by controlling the opening direction of the first three-way valve and the second three-way valve, the water can be controlled to flow from the water circuit of the drive motor to the water circuit of the generator controller, or the water can be controlled to flow from the water circuit of the generator controller to the water circuit of the drive motor. This allows for intelligent regulation of the heat exchange priority between the drive motor and the generator controller. Alternatively, when the drive motor and the generator controller do not need to exchange heat, the water can be controlled to flow directly from the first three-way valve to the second three-way valve without passing through the water circuits of the drive motor and the generator controller, thereby reducing the flow resistance of the water and minimizing the energy consumption of the water pump 102, thus improving the heat exchange efficiency of the dual-electric control system.

[0049] In one embodiment, when the inlet of the first three-way valve is connected to the first outlet of the first three-way valve, the water circuit of the first three-way valve and the drive motor are connected.

[0050] When the inlet of the first three-way valve is connected to the second outlet of the first three-way valve, the water circuit of the first three-way valve and the generator controller are connected.

[0051] When the first outlet of the second three-way valve is connected to the inlet of the second three-way valve, the water circuit of the drive motor is connected to the second three-way valve;

[0052] When the second outlet of the second three-way valve is connected to the inlet of the second three-way valve, the water circuit of the generator controller is connected to the second three-way valve.

[0053] According to the heat exchange requirements, the inlet of the first three-way valve can be connected to the first outlet or the second outlet of the first three-way valve, thereby controlling the water to flow preferentially to the water circuit of the drive motor or the water circuit of the generator controller. By controlling the inlet of the second three-way valve to be connected to the first outlet or the second outlet of the second three-way valve, the water can be controlled to continue flowing smoothly to the second three-way valve.

[0054] In one embodiment, it also includes:

[0055] The water circuit 106 of the synthesis controller is connected between the outlet of the water pump and the inlet of the first three-way valve;

[0056] The radiator 107 is connected between the outlet of the second three-way valve and the inlet of the water pump.

[0057] The synthesized controller can be a DC-DC / OBC synthesized controller. An OBC (On-board charger) is a charger permanently installed on an electric vehicle, capable of safely and automatically fully charging the vehicle. It's an energy conversion device that converts alternating current (AC) to direct current (DC), hence also called an AC / DC charger. A DC / DC converter is a converter that transforms a specific DC power supply voltage into any arbitrary DC voltage.

[0058] The heat sink can be a low-temperature heat sink with an electric fan assembly.

[0059] Radiators are used to exchange heat with water flowing in the water circuit of a heat exchange system.

[0060] The dotted line connecting the radiator 107 and the vehicle expansion tank 101 is used to allow the radiator 107 to drain water containing air bubbles into the vehicle expansion tank 101, so that the radiator 107 can remove air from the water in time. The water in the vehicle expansion tank 101 is added during the vehicle production process. The vehicle's VCU (Vehicle Control Unit) controls the opening direction of the three-way valve 103, as well as the start-up, power, and start-up and speed of the water pump, radiator 107.

[0061] Figure 3 A flowchart of a heat exchange method 300 for an electric vehicle with dual electronic controls according to an embodiment of the present disclosure is shown. Method 300 is used in a heat exchange system for an electric vehicle with dual electronic controls as described in any of the above embodiments, and method 300 may include:

[0062] Step 310: Obtain the current operating status of the electric vehicle, wherein the current operating status includes: the current temperature of each of the dual electronic controls;

[0063] Step 320: Control the two three-way valves in the heat exchange system of the dual-electric-controlled electric vehicle according to the current working state.

[0064] By acquiring the current operating status of the electric vehicle, the two three-way valves in the heat exchange system of the dual-electric-controlled electric vehicle can be automatically controlled. By controlling the opening direction of the two three-way valves, the heat exchange priority of the drive motor and generator controller can be intelligently adjusted to meet different heat exchange priority requirements, minimize water pump energy consumption, and improve heat exchange efficiency. In this way, the performance output of the dual-electric control can be maximized, avoiding any impact on vehicle performance, and enabling the dual-electric-controlled electric vehicle to effectively perform heat exchange.

[0065] In some embodiments, controlling the two three-way valves in the heat exchange system of the dual-electric-controlled electric vehicle according to the current operating state includes:

[0066] If the current temperature of each of the two electronic controllers is higher than the maximum value of their respective optimal operating temperature range or the current temperature of each of the two electronic controllers is lower than the minimum value of their respective optimal operating temperature range, and the current temperature of the drive motor is greater than the current temperature of the generator controller, then the water circuit between the first three-way valve and the drive motor and the water circuit between the second three-way valve and the generator controller are connected.

[0067] If the current temperature of each of the two electronic controllers is higher than the maximum value of their respective optimal operating temperature range, and the current temperature of the drive motor is higher than the current temperature of the generator controller, it indicates that the two electronic controllers are relatively hot and need cooling, and the drive motor needs cooling more than the generator controller. Therefore, the water circuit between the first three-way valve and the drive motor, and the water circuit between the second three-way valve and the generator controller can be controlled. This controls the water to flow from the first three-way valve to the drive motor's water circuit first, so as to cool the drive motor, and then flow to the generator controller's water circuit to continue cooling the generator controller. In this way, the heat exchange priority can be met by cooling the drive motor first and then the generator controller, achieving a rapid response to the heat exchange needs of the drive motor.

[0068] or

[0069] If the current temperature of each of the two electronic controllers is lower than the minimum value of their respective optimal operating temperature range, and the current temperature of the drive motor is higher than the current temperature of the generator controller, it indicates that the temperature of both electronic controllers is too low and they both need to be heated. The generator controller needs more heating than the drive motor. Since the two electronic controllers generate heat when they are working, the first three-way valve of the two three-way valves can be connected to the water circuit of the drive motor, and the second three-way valve of the two three-way valves can be connected to the water circuit of the generator controller. This controls the water to flow from the first three-way valve to the water circuit of the drive motor first, so as to use the heat generated by the drive motor to heat the water and then heat the generator controller as the water flows to the water circuit of the generator controller. In this way, the waste heat of the drive motor is used to heat the generator controller, which also improves the heat exchange efficiency of the whole vehicle, allowing the two electronic controllers to quickly reach the temperature range required for their optimal performance.

[0070] In some embodiments, controlling the two three-way valves in the heat exchange system of the dual-electric-controlled electric vehicle according to the current operating state includes:

[0071] If the current temperature of each of the two electronic controllers is higher than the maximum value of their respective optimal operating temperature range or the current temperature of each of the two electronic controllers is lower than the minimum value of their respective optimal operating temperature range, and the current temperature of the generator controller is greater than the current temperature of the drive motor, then the water circuit between the first three-way valve and the generator controller, and the water circuit between the second three-way valve and the drive motor are connected.

[0072] If the current temperature of each of the two electronic controllers is higher than the maximum value of their respective optimal operating temperature range, and the current temperature of the generator controller is higher than the current temperature of the drive motor, it indicates that the two electronic controllers are relatively hot and require cooling. Since the generator controller is hotter, it requires cooling more than the drive motor. Therefore, the first three-way valve can be connected to the water circuit of the generator controller, and the second three-way valve can be connected to the water circuit of the drive motor. This controls the water flowing from the first three-way valve to first flow to the water circuit of the generator controller, cooling the generator controller before flowing to the water circuit of the drive motor to further cool it. Figure 4 As shown, this allows for prioritizing the cooling of the generator controller before cooling the drive motor, based on heat exchange priority requirements, thus enabling a rapid response to the heat exchange needs of the drive motor.

[0073] or

[0074] If the current temperature of each of the two electronic controllers is lower than the minimum value of their respective optimal operating temperature range, and the current temperature of the generator controller is higher than the current temperature of the drive motor, it indicates that the temperature of both electronic controllers is too low and they both need heating. However, the current temperature of the drive motor is even lower, so the drive motor needs more heating than the generator controller. Since the two electronic controllers generate heat when they are working, the first three-way valve of the two three-way valves can be connected to the water circuit of the generator controller, and the second three-way valve of the two three-way valves can be connected to the water circuit of the drive motor. This controls the water to flow from the first three-way valve to the water circuit of the generator controller first, so that the heat generated by the generator controller after it is working can be used to heat the water and then heat the drive motor as the water flows to the water circuit of the drive motor. This also improves the heat exchange efficiency of the whole vehicle, allowing the two electronic controllers to quickly reach the temperature range required for them to perform at their best.

[0075] In some embodiments, the current operating state further includes: the current vehicle speed and whether the vehicle currently needs charging;

[0076] The step of controlling the two three-way valves in the heat exchange system of the dual-electric-controlled electric vehicle according to the current operating state includes:

[0077] If the current temperature of each of the two electronic controllers is within its optimal operating temperature range, or the current vehicle speed is lower than the preset vehicle speed and the vehicle does not currently need charging, and the synthesis controller in the heat exchange system needs heat exchange, then the first three-way valve of the two three-way valves is connected to the water circuit of the drive motor, and the second three-way valve of the two three-way valves is connected to the water circuit of the drive motor; or the first three-way valve of the two three-way valves is connected to the water circuit of the generator controller, and the second three-way valve of the two three-way valves is connected to the water circuit of the generator controller.

[0078] If the current temperature of each of the two electronic controllers is within its optimal operating temperature range, it indicates that neither of the two electronic controllers needs heat exchange. Alternatively, since the drive motor is responsible for driving and the generator controller is responsible for charging the battery, if the current vehicle speed is lower than the preset speed and the vehicle does not currently need charging, it indicates that the drive motor does not need to drive and the generator controller does not need to work. In other words, the two electronic controllers do not need to work and therefore do not need heat exchange. Thus, the first three-way valve can be controlled to connect with the water circuit of the drive motor and the second three-way valve, or the first three-way valve can be controlled to connect with the water circuit of the generator controller and the second three-way valve can be controlled to connect directly with the generator controller. In this case, the water in the water circuit does not need to pass through the water circuit of the drive motor and the water circuit of the generator controller, so the flow resistance is reduced. Therefore, the water pump can operate with lower power, thereby reducing the energy consumption of the water pump. This reduces the energy consumption of the heat exchange system, increases the vehicle's range, improves charging performance, and shortens the charging time.

[0079] The following will combine Figure 4 Further explanation of the technical solution disclosed herein, wherein, Figure 4 In this context, Tm: MCU temperature, °C; Tg: GCU temperature, °C; ΔTm: MCU temperature rise rate, °C / min; ΔTg: GCU temperature rise rate, °C / min.

[0080] like Figure 4As shown, when the current temperatures of both electronic controllers are higher than the maximum value of their respective optimal operating temperature ranges, if the current temperature Tm of the drive motor MCU is greater than the current temperature Tg of the generator controller GCU, priority should be given to cooling the MCU (of course, if Tm = Tg, but ΔTm is greater than or equal to ΔTg, priority should still be given to cooling the MCU), that is, controlling the first three-way valve's ports 1 and 2 to be open and the second three-way valve's ports 1 and 3 to be open (the first three-way valve is connected to the water circuit of the drive motor, and the second three-way valve is connected to the water circuit of the drive motor). (The three-way valve is connected to the water circuit of the generator controller). Conversely, if the current temperature Tm of the drive motor MCU is less than the current temperature Tg of the generator controller GCU, it is necessary to prioritize heat dissipation of the GCU (of course, if Tm = Tg, but ΔTm is less than ΔTg, it is still necessary to prioritize heat dissipation of the GCU), that is, to control the connection of port 1 and port 3 of the first three-way valve and the connection of port 2 and port 3 of the second three-way valve (the first three-way valve is connected to the water circuit of the generator controller and the second three-way valve is connected to the water circuit of the drive motor).
