[0025] In view of the distributed electrical and electronic architecture of cars on the market, most automotive fuses use traditional current fuses, which mainly play an overload protection function. With the rapid development of electrical and electronic architecture, traditional current fuses are no longer suitable for the high efficiency and intelligence requirements of domain controllers. Among them, the Efuse chip and high-side driver chip integrated in the domain controller are more suitable for the domain centralized electrical and electronic architecture.
[0026] However, only some electrical appliances are integrated in the domain controller, and most electrical appliances in the car are not domain integrated, that is, the Efuse chip and the high-side driver chip cannot meet the needs of all electrical appliances in the car. Therefore, there is an urgent need for a power control method that can be used for both distributed electronic and electrical architectures and domain centralized electronic and electrical architectures to meet the current flexible electronic and electrical architecture design.
[0027] Based on the above problems, the present application provides a power control method, which helps to reasonably control the power supply to various electrical appliances in the car and meet the current electronic and electrical architecture requirements in the car.

[0030] The melting heat energy value of the first fuse 101 is higher than that of the second fuse 102 , and the melting heat energy value of the second fuse 102 is higher than that of the third fuse 103 .

[0032] In some optional embodiments, the first fuse 101 may be used to control the power supply of the vehicle-level electrical appliance 11. The second fuse 102 may be used to control the power supply of the system-level electrical appliance 12. The third fuse 103 may be used to control the power supply of a single electrical appliance 13.
[0033] The vehicle-level electrical appliances 11 may include but are not limited to a conversion and distribution unit (CDU), a battery, etc. The system-level electrical appliances may include but are not limited to a domain controller, electrical appliances for different key positions, etc.
[0034] It is understandable that the domain controller may include an E-Fuse chip and / or a high-side driver chip.
[0035] Figure 2 A schematic flow chart of an embodiment of a power control method provided in the present application includes the following steps: Step 201, identifying all electrical appliances in the vehicle.
[0036] Specifically, all electrical appliances in a vehicle may include vehicle-level electrical appliances, system-level electrical appliances, and single electrical appliances.
[0037] If the electrical appliance is a vehicle-level electrical appliance, execute step 202. Or, If the electrical appliance is a system-level electrical appliance, execute step 203. Or, If the electrical appliance is a single electrical appliance, step 204 is executed.
[0038] Step 202: Control the power supply of the vehicle-level electrical appliances through the first fuse.
[0039] The first fuse may be a fuse having a thermal energy threshold greater than or equal to a first melting thermal energy threshold.
[0040] Step 203: Control the power supply of the system-level electrical appliances through the second fuse.
[0041] The second fuse may be a fuse having a thermal energy lower than the first melting threshold and greater than or equal to the second melting threshold.
[0042] Step 204, obtaining electrical interface requirements and electrical parameters of a single electrical appliance.

[0048] Specifically, it can be determined whether the single electrical appliance uses a domain controller for power control or a third fuse for power control according to the electrical interface requirements and electrical parameters of the single electrical appliance.
[0049] The third fuse may be a fuse with a thermal energy lower than the second melting thermal energy threshold.
[0050] Figure 3 This is a flow chart of another embodiment of the power control method provided by the present application. Step 205 may include the following steps: Step 301 : determining whether the load of a single electrical appliance is sensitive to voltage fluctuations based on the electrical interface requirements and electrical parameters of the single electrical appliance.
[0051] Specifically, whether a single electrical load is sensitive to voltage fluctuations can be determined based on the operating voltage in the electrical interface requirements and the anti-interference capability in the electrical parameters.
[0052] Exemplarily, a method for determining whether a single electrical load is sensitive to voltage fluctuations may include: determining whether a sensitivity value of the single electrical load to voltage fluctuations is greater than a first preset threshold, wherein the sensitivity value may be determined by an operating voltage and anti-interference capability.
[0053] If the sensitivity value of a single electrical load to voltage fluctuation is greater than a first preset threshold, it can be considered that the single electrical load is sensitive to voltage fluctuation. If the sensitivity value of a single electrical load to voltage fluctuation is less than or equal to a first preset threshold, it can be considered that the single electrical load is not sensitive to voltage fluctuation.
[0054] It is understandable that the above examples are only illustrative of the operating voltage and anti-interference capability, and do not constitute a limitation on the embodiments of the present application. In some embodiments, other parameters can also be used to determine whether the load is sensitive to voltage fluctuations.
[0055] If the single electrical load is sensitive to voltage fluctuations, execute step 302. Alternatively, If the single electrical load is not sensitive to voltage fluctuations, step 303 is executed.
[0056] Step 302: Power control of a single electrical appliance is performed through a domain controller.
[0057] It is understandable that the domain controller may include an E-Fuse chip and a high-side driver chip.
[0058] In some optional embodiments, the high-side driver chip may be used to control the power supply of the single electrical appliance.

[0066] In some optional embodiments, the appliance type may also include a vibration level.
[0067] Step 405, determining a fuse used by the single electrical appliance according to the type of the single electrical appliance to perform power control.
[0068] Specifically, it can be determined according to the type of the single electrical appliance whether the single electrical appliance uses the domain controller for power control or uses the third fuse for power control.

Step 405 may include the following steps: Step 501, judging whether the single electrical appliance is a high safety factor electrical appliance according to the electrical appliance type of the single electrical appliance.
[0070] Specifically, whether a single electrical appliance is a high safety factor electrical appliance can be determined based on the safety level of the electrical appliance type.
[0071] Exemplarily, a method of determining whether a single electrical appliance is a high-safety-factor electrical appliance may include: determining whether the safety factor of the single electrical appliance is greater than a second preset threshold.
[0072] If the safety factor of a single electrical appliance is greater than the second preset threshold, the single electrical appliance can be considered as a high safety factor electrical appliance. If the safety factor of a single electrical appliance is less than or equal to the second preset threshold, it can be considered that the single electrical appliance is not a high safety factor electrical appliance.
[0073] It is understandable that the above examples are merely illustrative of the safety level and do not constitute a limitation on the embodiments of the present application. In some embodiments, other parameters may also be used to determine whether an electrical appliance has a high safety factor.
[0074] If the single electrical appliance is a high safety factor electrical appliance, execute step 502. Or, If the single electrical appliance is not a high safety factor electrical appliance, step 503 is executed.
[0075] Step 502: Power control of a single electrical appliance is performed through a domain controller.
[0076] In some optional embodiments, the power supply of the single electrical appliance may be controlled by an E-Fuse chip.
[0077] Step 503: Control the power supply of a single electrical appliance through the third fuse.
