In this embodiment of the application, the power battery module 100a may be composed of at least one lithium-ion battery.

It also supplies power to the DC-DC converter module 100e when the battery charge of the electric vehicle is below a specified threshold. Pure electric mode is when the electric vehicle is driven by power supplied by the power battery module 100a. The power battery module 100a stops supplying power to the heating control module 100d, the air conditioning control module 100f, the drive module 100c, and the DC-DC converter module 100e when the electric vehicle is in range-extended mode.

[0055] In this embodiment, under pure electric conditions, the power battery module directly supplies power to the heating control module, air conditioning control module, and drive module, reducing intermediate energy conversion steps, effectively reducing energy loss, and improving energy transmission efficiency. Under range-extended conditions, the power battery module stops supplying power to other modules, and the generator module supplies power and charges the power battery, effectively avoiding frequent charging and discharging of the power battery when it is low in charge, thus extending battery life. Through the connection and functional allocation of each module in the above-mentioned electric vehicle power supply high-voltage architecture system, energy transmission efficiency is improved while ensuring the health of the hardware, thereby improving the overall power distribution efficiency of the vehicle.

[0056] based on Figure 1 Please refer to Figure 2 , Figure 2 This is a structural diagram of a high-voltage power supply architecture system for electric vehicles according to one embodiment of this application. Figure 2As shown, the electric vehicle power supply high-voltage architecture system 100 also includes a thermal management controller module 100i, which is connected to the power battery module 100a and the generator module 100b respectively. The thermal management controller module 100i is used to monitor the temperature of the power battery module 100a and the generator module 100b when the electric vehicle is in range-extending mode, and adjust the output power of the power battery module 100a and the generator module 100b based on the monitored temperature so that the output power of the power battery module 100a and the generator module 100b are within a safe range.

[0057] Among them, the thermal management controller module 100i is a control module in the high-voltage architecture system for electric vehicle power supply, which can be used to monitor and regulate the operating temperature of the power battery module 100a and the generator module 100b.

[0058] In this embodiment, the thermal management controller module 100i can collect temperature data of the power battery module 100a and the generator module 100b in real time through temperature sensors, and adjust the output power of the power battery module 100a and the output power of the generator module 100b based on the measured temperature data to ensure that the high-voltage power supply architecture system of the electric vehicle operates within a safe range.

[0059] In this embodiment, the electric vehicle power supply high-voltage architecture system introduces a thermal management controller module. The thermal management controller module is directly connected to the power battery module and the generator module, and can monitor the operating temperature of these two modules in real time. When an abnormal operating temperature is detected, the output power of the power battery and the output power of the generator are dynamically adjusted to avoid performance degradation or damage caused by overheating or overcooling, and effectively ensure the safety of the vehicle power distribution process.

[0060] based on Figure 1 Please refer to Figure 3 , Figure 3 This is a structural diagram of a high-voltage power supply architecture system 100 for electric vehicles according to one embodiment of this application. Figure 3 As shown, the electric vehicle power supply high-voltage architecture system 100 also includes a vehicle control module 100j, which is connected to the power battery module 100a and the generator module 100b respectively. The vehicle control module 100j is used to control the power supply power of the generator module 100b to the power battery module 100a, heating control module 100d, DC-DC converter module 100e and air conditioning control module 100f according to the power consumption priority of the power battery module 100a, heating control module 100d, DC-DC converter module 100e and air conditioning control module 100f when the electric vehicle is in range-extending mode.

[0061] Among them, the vehicle control module 100j is the control module in the electric vehicle, which is responsible for coordinating and managing the energy distribution and scheduling among the various power-consuming modules in the electric vehicle.

[0062] In this embodiment of the application, the vehicle control module 100j can monitor the power demand of each module in the electric vehicle in real time, and adjust the power supply priority of the generator module 100b to each module according to the power demand of each module.

[0063] The aforementioned power demand refers to the amount of electrical energy required by each power module under specific operating conditions. The power demand of each module will vary according to the actual operating conditions of the electric vehicle (such as vehicle temperature, vehicle driving mode, etc.).

[0064] In this embodiment of the application, the electric vehicle can monitor the working status of each power module in real time through vehicle sensors, and further determine the power demand based on the working status; or directly obtain the current power and target power consumption of each power module.

[0065] For example, electric vehicles can obtain the current interior temperature through temperature sensors, and based on the current interior temperature, further determine the amount of electrical energy required by the heating control module or air conditioning control module.

[0066] In some embodiments, the vehicle control module is configured to control the power supply from the generator module to the power battery module, heating control module, DC-DC converter module, and air conditioning control module according to the priority of the power demand of the power battery module, heating control module, DC-DC converter module, and air conditioning control module when the electric vehicle is in range-extended operation mode.

[0067] In this embodiment of the application, after the electric vehicle obtains the power demand of each power module, it controls the power supply of the generator module to each power module according to the size of the power demand through the vehicle control module. In other words, the generator module is controlled to prioritize supplying power to the power module with the largest power demand.

[0068] For example, the power battery module requires 5 kW of charging power, the heating control module requires 3 kW at full power, the air conditioning control module requires 2 kW at full power, and the DC-DC converter module requires 1 kW at full power. The vehicle control module first assesses the power demand of each of the above power modules and sorts them according to the priority of the power demand (i.e., the urgency of the power demand). Assuming the priority from high to low is: the power battery module is the first priority, the heating control module and the air conditioning control module are the second priority, and the DC-DC converter module is the third priority, the vehicle control module schedules the generator module to prioritize providing 5 kW of power to the first priority power battery module, 1.5 kW to the second priority heating control module, 1 kW to the second priority air conditioning control module, and 0.3 kW to the third priority DC-DC converter module.

[0069] In this embodiment, when the electric vehicle is in range-extended mode, the vehicle control module can dynamically adjust the power supply priority of the generator module by monitoring the power demand of the power battery module, heating control module, DC-DC conversion module and air conditioning control module in real time. This ensures accurate power supply according to the actual situation of the electric vehicle. By adjusting the power supply priority through a dynamic scheduling mechanism, the power supply power of each module is reasonably scheduled, optimizing the overall power distribution of the electric vehicle and thus effectively improving the power distribution efficiency of the whole vehicle.

[0070] Please refer to Figure 4 , Figure 4 A flowchart of an embodiment of an electric vehicle power supply method relates to this application. (See attached flowchart.) Figure 4 As shown, the method can be executed by an electric vehicle through an electric vehicle power supply high-voltage architecture system (hereinafter referred to as the system), which can be the aforementioned Figure 1 The electric vehicle power supply high-voltage architecture system 100 shown includes a power battery module, a generator module, a heating control module, a DC-DC converter module, an air conditioning control module, a slow charging module, a fast charging module, and a drive module; the method includes steps 410a, 420a, 405, 410b, 420b, 430a, and 430b.

[0071] Step 410a: When the electric vehicle is in pure electric mode, the power battery module supplies power to the heating control module, air conditioning control module and drive module respectively; pure electric mode is the mode in which the electric vehicle is driven by the power battery module.

[0072] In this embodiment of the application, the system can monitor the working status of the electric vehicle in real time. When the system detects that the electric vehicle is in pure electric mode, it supplies power to the heating control module, the air conditioning control module and the drive module through the power battery module.

[0073] Step 420a: When the battery charge of the electric vehicle is lower than the specified charge threshold, power is supplied to the DC-DC converter module through the power battery module.

[0074] The specified power threshold can be a preset minimum power level required to maintain the normal operation of the electric vehicle. The system can monitor the power level of the electric vehicle's battery in real time. When the power level of the electric vehicle's battery is lower than the specified power threshold, it indicates that the electric vehicle cannot maintain normal operation, and the system supplies power to the DC-DC converter module through the power battery.

[0075] Step 405: When the electric vehicle is in range-extending mode, the power battery module stops supplying power to the heating control module, air conditioning control module, drive module and DC-DC conversion module.

[0076] Step 410b: When the electric vehicle is in range-extending mode, the generator module generates electricity to supply power to the power battery module, heating control module, and air conditioning control module respectively; range-extending mode is the mode in which the electric vehicle is driven by the generator module.

[0077] Step 420b: When the battery charge of the electric vehicle is lower than the specified charge threshold, power is supplied to the DC-DC converter module by generating electricity through the generator module.

[0078] Step 430a: With the power battery module connected to the slow charging gun, the power battery module is charged at the first charging power through the slow charging module.

[0079] Step 430b: With the power battery module connected to the fast charging gun, the power battery module is charged by the fast charging module at a second charging power; the second charging power is higher than the first charging power.

[0080] In this embodiment, under pure electric conditions, the power battery module directly supplies power to the heating control module, air conditioning control module, and drive module, reducing intermediate energy conversion steps, effectively reducing energy loss, and improving energy transmission efficiency. Under range-extended conditions, the power battery module stops supplying power to other modules, and the generator module supplies power and charges the power battery, effectively avoiding frequent charging and discharging of the power battery when it is low in charge, thus extending battery life. Through the connection and functional allocation of each module in the above-mentioned electric vehicle power supply high-voltage architecture system, the overall vehicle power distribution efficiency is improved.

[0081] Based on the solutions shown in any one or more of the above embodiments, in some embodiments, step 410a can be implemented as follows: when the electric vehicle is in pure electric mode, power is supplied to the heating control module through the power battery module so that the heating control module can heat the resistor for heating; power is supplied to the air conditioning control module through the power battery module so that the air conditioning compressor of the electric vehicle can be started for cooling; power is supplied to the drive module through the power battery so that the electric vehicle can be driven; step 420a can be implemented as follows: when the battery charge of the electric vehicle is lower than a specified charge threshold, power is supplied to the DC-DC conversion module through the power battery module so that the DC-DC conversion module can convert the received power into electricity. The high-to-low power conversion is supplied to the electric vehicle's battery; step 410b above can be implemented as follows: when the electric vehicle is in range-extending mode, the generator module generates electricity to charge the power battery module; the generator module generates electricity to directly supply power to the heating control module so that the heating control module can heat the resistors for heating; the generator module generates electricity to directly supply power to the air conditioning control module so that the electric vehicle's air conditioning compressor can be started for cooling; step 420b above can be implemented as follows: when the electric vehicle's battery power is lower than a specified power threshold, the generator module generates electricity to supply power to the DC-DC conversion module so that the DC-DC conversion module can convert the received power from high to low to the electric vehicle's battery.

[0082] In this embodiment, under pure electric conditions, the system can directly power the heating control module, air conditioning control module, and drive module through the power battery module, reducing energy conversion losses during power supply and improving energy utilization efficiency. When the battery charge of the electric vehicle is lower than a specified threshold, the power battery module prioritizes powering the DC-DC converter module to ensure the normal operation of low-voltage electrical equipment. Under range-extended conditions, the generator module not only charges the power battery but also directly powers the heating module and air conditioning module. In the above scheme, the system dynamically adjusts the output power according to the actual needs of each power-consuming module of the electric vehicle through the generator module, flexibly allocating power and effectively improving the efficiency of the vehicle's power distribution.

[0083] Based on the solutions shown in any one or more of the above embodiments, in some embodiments, when the electric vehicle is in range-extended operation, the electric vehicle power supply high-voltage architecture system monitors the temperature of the power battery module and the generator module through the thermal management controller module; and adjusts the output power of the power battery module and the output power of the generator module based on the monitored temperature so that the output power of the power battery module and the output power of the generator module are within a safe range.

[0084] In this embodiment, when the electric vehicle is in range-extended mode, the thermal management controller module can monitor the temperature of the power battery module and the generator module in real time through the built-in temperature sensor. When the operating temperature of the power battery module or the generator module exceeds the preset safe temperature, the power battery module or the generator module is adjusted.

[0085] For example, if the operating temperature of the power battery module is too high, the thermal management controller module reduces the output power of the power battery module to prevent the power battery from overheating and being damaged.

[0086] For example, if the generator module's operating temperature is too high, and it exceeds the safe operating temperature, the thermal management controller module adjusts the generator module's output power to prevent the generator module from overheating and causing a decrease in efficiency.

[0087] In some embodiments, when the electric vehicle is in range-extended operation, the system monitors the temperature of the power battery module and the generator module through the thermal management controller module; based on the monitored temperature, it issues a warning message indicating that there is a potential risk to the output power of the power battery module and the output power of the generator module, and that timely adjustment is required.

[0088] In this embodiment, when the thermal management controller module detects that the operating temperature of the power battery module and the generator module is about to exceed the safe temperature, the thermal management controller module generates a prompt message indicating that there is a potential risk to the output power of the power battery module and the output power of the generator module, and suggests timely adjustment.

[0089] For example, if the operating temperature of the power battery module is about to exceed the safe temperature, the thermal management controller module generates a warning message: "The current temperature of the power battery module is approaching the warning limit. Please adjust the output power to avoid overheating risk," and displays this information on the vehicle's display screen.

[0090] In this embodiment, the system monitors the temperature of the power battery module and the generator module in real time through the thermal management controller module, and dynamically adjusts the output power and efficiency of the power battery module and the generator module based on the monitored temperature data to ensure that they are always within a safe range. This avoids equipment damage or performance degradation caused by overheating of the power battery module and the generator module. The system also adjusts the power distribution in real time according to the monitored temperature, ensuring the safety of the power modules while avoiding unnecessary energy waste and improving the efficiency of the vehicle's power distribution.

[0091] Based on the solutions shown in any one or more of the above embodiments, in some embodiments, when the electric vehicle is in range-extended operation, the electric vehicle power supply high-voltage architecture system controls the power supply of the generator module to the power battery module, heating control module, DC-DC conversion module and air conditioning control module according to the power consumption priority of the power battery module, heating control module, DC-DC conversion module and air conditioning control module through the vehicle control module.

[0092] In this embodiment, when the electric vehicle is in range-extended mode, the vehicle control module monitors the power demand of the power battery module, heating control module, DC-DC conversion module and air conditioning control module in real time, dynamically adjusts the power supply priority of the generator module, avoids unnecessary energy waste through dynamic scheduling mechanism, optimizes the overall energy distribution, and thus effectively improves the power distribution efficiency of the whole vehicle.

[0093] Based on the solutions shown in any one or more of the above embodiments, in some embodiments, the vehicle controller of the electric vehicle includes the above-described... Figures 1 to 3 The electric vehicle power supply high-voltage architecture system shown in any one of the diagrams includes a power battery module, a generator module, a heating control module, a DC-DC converter module, an air conditioning control module, a slow charging module, a fast charging module, and a drive module. The vehicle control system can implement the electric vehicle power supply method, and the specific implementation process is as follows.

[0094] When an electric vehicle is in pure electric mode, the power battery module supplies power to the heating control module, air conditioning control module, and drive module respectively; pure electric mode is the mode in which the electric vehicle is driven by the power battery module.

[0095] When the battery charge of an electric vehicle is lower than a specified charge threshold, power is supplied to the DC-DC converter module through the power battery module;

[0096] When the electric vehicle is in range-extending mode, the power battery module stops supplying power to the heating control module, air conditioning control module, drive module and DC-DC conversion module;

[0098] When the battery charge of the electric vehicle is lower than a specified charge threshold, the generator module generates electricity to supply power to the DC-DC conversion module.

[0099] When the power battery module is connected to the slow charging gun, the power battery module is charged at the first charging speed through the slow charging module.
