DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Global climate change caused by carbon dioxide and other greenhouse gas emissions has become one of the major challenges that all mankind needs to face. As an emerging technical means of energy conservation and emission reduction, hybrid vehicles have broad future development prospects. Since the temperature operating ranges of various systems and components of extended-range hybrid vehicles vary greatly, in order to maintain the temperature of most components, external means are needed to control the temperature within an appropriate temperature range to ensure stable and efficient operation of the components. The electric drive system, battery and engine body coexist and can provide power to the entire vehicle simultaneously or separately. Therefore, ensuring that each system is at the optimal operating temperature under all working conditions and all weather conditions can ensure the stability of the power system.

[0042] During vehicle driving, the battery or electric drive system needs to be in an optimal temperature state to improve vehicle performance. In the existing technology, a heating and cooling system is often used to coordinate the work. When the battery system temperature is low, the battery system is heated, and when the battery system temperature is high, the battery system is cooled; and the electric drive system and engine system are cooled. This consumes a lot of energy, and the heat of the electric drive system and engine system is wasted.

[0043] In view of this, the embodiment of the present application proposes a uniform temperature cooling water path architecture, referring to Figure 1 , the waterway architecture includes:

[0044] Electric drive system circuit 1, battery system circuit 2, engine system circuit 3 and cooling water circuit 4;

[0045] The electric drive system circuit 1 is connected to both ends of the battery system circuit 2 so that the electric drive system circuit 1 can evenly temperature the battery system circuit 2.

[0046] Under low temperature working conditions, the electric drive system generates heat when working, so the heating demand is increased, while the battery system has higher temperature requirements. Therefore, the electric drive system is cooled through the electric drive system circuit 1, and then the heat is transferred to the battery system through the battery cooling system, thereby achieving uniform temperature between the electric drive system and the battery system.

[0047] The battery system loop 2 includes a heater 26. The engine system loop 3 is connected to both ends of the heater 26 so that heat from the engine system loop 3 is transferred to the heater 26. The heater 26 is used to provide heat for the battery system loop 2. A shut-off valve 14 is provided between the heater 26 and the engine system loop 3.

[0048] During operation, the engine body 33 generates a lot of heat. The shut-off valve 14 is opened, and the heat of the engine body 33 is transferred to the heater 26 through the engine system loop 3. Then the heater 26 heats the battery body 23 through the battery system loop 2, thereby utilizing the heat of the engine body 33 and heating the battery system at the same time.

[0049] The cooling water circuit 4 and the engine system circuit 3 are connected in parallel, so that the cooling water circuit 4 cools the engine system circuit 3 .

[0050] When the engine main body 33 operates normally, the engine main body 33 is cooled by the cooling water path 4 , so that the engine main body 33 maintains a normal operating temperature.

[0051] The present application provides a uniform temperature cooling water circuit 4 architecture for an electric drive system and a battery system and a vehicle, the water circuit architecture including: an electric drive system circuit 1, a battery system circuit 2, an engine system circuit 3 and a cooling water circuit 4. Among them, the electric drive system circuit 1 is connected to the battery system circuit 2 at both ends. Under cold working conditions, the electric drive system circuit 1 transfers the heat generated by the electric drive system to the battery system, thereby keeping the electric drive circuit and the battery circuit at a uniform temperature; when the battery system needs to be heated, the engine system supplies heat to the heater 26 in the battery system to heat the battery system; at the same time, the engine system is cooled by the cooling water circuit 4, so that the engine body 33 is kept at the optimal operating temperature. By mutual heating, uniform temperature or cooling between the electric drive system circuit 1, the battery system circuit 2, the engine system circuit 3 and the cooling water circuit 4, the heat inside the vehicle is effectively utilized, reducing the energy consumption of heating the battery system and the energy consumption of cooling the electric drive system and the engine system.

[0052] In some embodiments, the battery system circuit 2 is provided with: a first pump body 21, a PTC heating module 22, a battery body 23, and an overflow tank 24;

[0053] The first pump body 21 is used to drive the entire battery system loop 2 to operate, and the overflow tank 24 is used to store cooling water overflowed during the heating process in the loop.

[0054] The input end of the first pump body 21 is connected to the overflow tank 24, and the output end of the first pump body 21 is connected to the PTC heating module 22; the PTC heating module 22, the battery body 23 and the heater 26 are connected in sequence, and the heater 26 is connected to the overflow tank 24 to form a battery system loop 2 to heat or uniformly heat the battery body 23.

[0055] When the battery body 23 is in a low temperature condition and the engine body 33 is working, the engine system supplies heat to the heater 26 in the battery system, and the third pump body 53 drives the entire battery system loop 2 to operate, thereby heating the battery system through the heater 26.

[0056] When the vehicle is just started, the battery body 23 needs to be heated separately. The third pump body 53 drives the entire battery system loop 2 to operate, and the PTC heating module 22 starts heating, thereby achieving separate heating of the battery body 23.

[0057] The engine system circuit 3 is provided with: a second pump body 31, the input end of the second pump body 31 is connected to the output end of the cooling water circuit 4, and the output end of the second pump body 31 is connected to the engine body 33; a TMM module 32, the input end of the TMM module 32 is connected to the engine body 33, and the output end is connected to the input end of the cooling water circuit 4;

[0058] The input end of the heater 26 is connected to the output end of the TMM module 32 , and the output end of the heater 26 is connected to the output end of the second pump body 31 , so that the electric drive system circuit 1 can uniformly temperature the battery system circuit 2 .

[0059] When the vehicle is in a cold working condition, the engine body 33 generates heat, and the second pump body 31 works to pump the cooling water cooled by the cooling water path 4 to the engine body 33 to cool the engine body 33. Then the cooling water adjusts the flow rate according to the needs of the battery system through the TMM module 32, so that part of the cooling water flows to the heater 26, heats the battery system loop 2 through the heater 26, and then returns to the second pump body 31; the other part is cooled through the cooling water path 4 and then returns to the pump body again.

[0060] In some embodiments, the water channel structure also includes: a warm air water channel 6, the input end of the warm air water channel 6 is connected to the output end of the TMM module 32, and the output end of the warm air water channel 6 is connected to the output end of the second pump body 31, so that the electric drive system loop 1 supplies heat to the warm air water channel 6.

[0061] The warm air water circuit 6 includes a warm air core 61, which is used to heat the interior of the vehicle. When the interior of the vehicle needs to be heated, the heat of the engine body 33 is transported to the warm air water circuit 6 through the TMM module 32, thereby sending the heat of the engine body 33 into the interior of the vehicle through the warm air core 61, thereby improving the utilization rate of the heat of the engine body 33 and achieving simultaneous heating of the battery system and the interior of the vehicle.

[0062] In some embodiments, the input end of the TMM module 32 is connected to the input end of the cooling water circuit 4 inside the engine body 33 through a water circuit, forming a small circulation. When the vehicle starts, the engine body 33 is heated by the TMM module 32, so that the engine body 33 quickly reaches the optimal operating temperature, thereby improving the starting efficiency of the vehicle.

[0063] In some embodiments, the electric drive system circuit 1 includes: a three-way proportional valve 11; a first branch 12 for cooling a first type of drive component, and a second branch 13 for cooling a second type of drive component; wherein the three valves of the three-way proportional valve 11 are respectively connected to the first branch 12, the second branch 13 and the input end of the first pump body 21.

[0064] Among them, the first type of driving components at least include a front drive motor body 121, a front drive motor controller 122 and a three-in-one controller 123; the second type of driving components at least include a rear drive motor body 131 and a rear drive motor controller 132.

[0065] When the vehicle is in different drive modes, different drive motors have different cooling requirements. When the vehicle is in front-wheel drive mode, the cooling water flow rate in the second branch 13 is reduced through the three-way proportional valve 11, and the cooling water flow rate in the first branch 12 is increased, thereby improving the cooling effect on the front-wheel drive motor body 121, the front-wheel drive motor controller 122, and the three-in-one controller 123. When the vehicle is in rear-wheel drive mode, the cooling water flow rate in the first branch 12 is reduced, and the cooling water flow rate in the second branch 13 is increased, thereby improving the cooling effect on the rear-wheel drive motor body 131 and the rear-wheel drive motor controller 132. When the vehicle is in all-wheel drive mode, the cooling water flow rate is distributed according to demand through the three-way proportional valve 11 to meet the cooling needs of different operating conditions.

[0066] In some embodiments, the front-drive motor body 121 is connected in series with the front-drive motor controller 122 and then connected in parallel with the three-in-one controller 123 .

[0067] When cooling the front-drive motor body 121 , the cooling water passes through the front-drive motor body 121 and the water path of the front-drive motor controller 122 and the water path of the three-in-one controller 123 in parallel, thereby reducing the resistance of the cooling water and improving the cooling effect.

[0068] The battery system loop 2 further includes a three-way valve 27 , the three valves of which are connected to the overflow tank 24 , the heater 26 and the electric drive system loop 1 respectively.

[0069] When the vehicle requires uniform temperature for the electric drive system and the battery system, the water path between the three-way valve 27 and the overflow tank 24 is closed through the three-way valve 27, so that the electric drive system and the battery system are connected in series, thereby achieving the effect of uniform temperature for the electric drive system and the battery system; when the battery system needs to be heated separately, the water path with the electric drive system is closed through the three-way valve 27, so that the battery system loop 2 forms a separate loop, and then is heated by the PTC heating module 22 to achieve separate heating of the battery system loop 2.

[0070] In some embodiments, a chiller module 25 is provided on the battery system loop 2 . The chiller module 25 is provided between the three-way valve 27 and the heater 26 for cooling the battery body 23 .

[0071] When the battery temperature is high, the battery body 23 is cooled by the chiller module 25 through the battery system module, so that the battery maintains a suitable operating temperature and improves the working state of the battery body 23.

[0072] In some embodiments, the water circuit architecture also includes: an oil cooler circuit 5, the oil cooler circuit 5 includes a third pump body 53, an oil cooler body 51 and a transmission 52, the oil cooler body 51 and the transmission 52 are connected in parallel, and are used to cool the transmission 52; the input end of the third pump body 53 is connected to the output end of the cooling water circuit 4, and the output end of the third pump body 53 is connected to the input end of the electric drive system circuit 1.

[0073] Among them, the water cooling circuit includes a high-temperature radiator 41, and the input end of the oil cooler circuit 5 is connected to the middle position of the high-temperature radiator 41. When the engine body 33 is not working but the transmission 52 needs to be cooled, the transmission 52 is cooled by the oil cooler body 51, and then the cooling water cooled by the lower half of the high-temperature radiator 41 is pumped into the cooling water path 4 of the oil cooler body 51 through the third pump body 53 to cool the oil cooler body 51, thereby achieving the effect of cooling the transmission 52 alone.

[0074] The present application also provides a control system for controlling the on and off of the stop valve 14, the three-way proportional valve 11 and the three-way valve 27, and for controlling the TMM module 32, the PCT module, the chiller module 25, the first pump body 21, the second pump body 31 and the third pump body 53.

[0075] When the vehicle is started by the engine body 33 , the control system closes the shutoff valve 14 and controls the TMM module 32 to form a small circulation between the TMM module 32 and the engine body 33 , thereby heating the engine body 33 and allowing the engine body 33 to quickly reach the operating temperature.

[0076] When the engine body 33 is working, the control system controls the TMM module 32 to close the small circulation, open the connection with the cooling water path 4, and control the second pump body 31 to start, pumping the cooling water cooled by the cooling water path 4 to the engine body 33 to cool the engine body 33 and improve the working performance of the engine body 33.

[0077] When the interior of the vehicle is heated, the control system closes the shut-off valve 14 and adjusts the cooling water flow through the warm air water path 6 by controlling the TMM module 32 according to the heating requirements of the warm air circuit and the temperature of the engine system circuit 3, thereby heating the warm air water path 6, achieving effective utilization of the heat of the engine body 33, and heating the interior of the vehicle at the same time, reducing energy consumption.

[0078] When the vehicle is in a low-temperature operating condition and the battery system is started or working, the control system opens the shut-off valve 14 and adjusts the cooling water flow through the heater 26 by controlling the TMM module 32 according to the heating requirements of the battery body 23 and the temperature of the engine system loop 3, thereby heating the battery system and the warm air water circuit 6, achieving effective utilization of the engine heat body 33, and heating the battery body 23 and the interior of the vehicle at the same time, reducing energy consumption.

[0079] When the engine body 33 is not operating and the vehicle is in a low-temperature operating condition, the control system controls the shutoff valve 14 to close, disconnecting the electric drive system circuit 1 from the battery system circuit 2 through the three-way valve 27, driving the battery system circuit 2 to form a separate circuit. The control system controls the operation of the third pump body 53, thereby driving the entire battery system circuit 2 to operate, and controls the PTC heating module 22 to start heating, thereby achieving independent heating of the battery body 23 when the engine body 33 is not operating. When the temperature of the battery body 23 is high, the control system controls the chiller module 25 to start heating, thereby achieving independent cooling of the battery body 23.

[0080] When the engine main body 33 is not working and the vehicle is in a low-temperature operating condition, after the electric drive system is started, the control system controls the shut-off valve 14 to close, and controls the three-way valve 27 to close the water path between the three-way valve 27 and the overflow tank 24, so that the electric drive system and the battery system are connected in series. The electric drive system circuit 1 transfers the heat generated by the electric drive system to the battery system, so that the electric drive circuit and the battery circuit maintain a uniform temperature, thereby achieving a uniform temperature effect for the electric drive system and the battery system.

[0081] After the electric drive system is activated, when the vehicle is in different drive modes, different drive motors have different cooling requirements. When the vehicle is in front-wheel drive mode, the control system controls the three-way proportional valve 11 to reduce the cooling water flow in the second branch 13 and increase the cooling water flow in the first branch 12, thereby improving the cooling effect on the front-wheel drive motor body 121, the front-wheel drive motor controller 122, and the three-in-one controller 123. When the vehicle is in rear-wheel drive mode, the control system controls the three-way proportional valve 11 to reduce the cooling water flow in the first branch 12 and increase the cooling water flow in the second branch 13, thereby improving the cooling effect on the rear-wheel drive motor body 131 and the rear-wheel drive motor controller 132. When the vehicle is in all-wheel drive mode, the control system controls the three-way proportional valve 11 to achieve on-demand distribution, thereby meeting the cooling needs under different operating conditions.
