The power component can include an electric motor that can convert electrical energy into mechanical energy to drive the vehicle and increase the vehicle's mileage.

[0063] It should be noted that the vehicle controller 101 can monitor and manage the status of the power battery 1041 , the power assembly 1042 and the vehicle accessories 1043 .
[0064] The above technical solution can provide electric energy to the power battery 1041, the power assembly 1042 and the vehicle accessories 1043 through the DC / DC converter 103, thereby increasing the vehicle's mileage.

When the current power of the power battery 1041 is greater than or equal to 100, in the order of the electric energy conversion efficiency from low to high (solar cell device 1022 < vibration generator device 1023 < thermoelectric conversion device 1024 < wind generator device 1025 < braking energy recovery device 1021), one or more of the solar cell device 1022, the vibration generator device 1023, the thermoelectric conversion device 1024, the wind generator device 1025 and the braking energy recovery device 1021 are controlled to stop working in sequence in the order from low to high.
[0067] It should be noted that, when the current power of the power battery 1041 is greater than or equal to the preset power threshold, the vehicle controller 101 controls the current power generation device to stop working in order of the power conversion efficiency from low to high, and when the power provided by the current power generation device is equal to the power consumed by the power module, the current power generation device is no longer controlled to stop working.

[0070] The above technical solution can control the current power generation device to provide electric energy to the power consumption module 104 when the current power of the power battery 1041 is less than the preset power threshold, thereby increasing the vehicle's mileage and effectively improving the vehicle's economic performance.
[0071] Optionally, Figure 2 As shown, the power battery 1041 is also connected to the power assembly 1042 and the vehicle accessories 1043; the vehicle controller 101 is used to obtain the total electric energy provided by the power generation module 102; the power battery 1041 is used to provide electric energy to the power assembly 1042 and the vehicle accessories 1043 when the total electric energy provided by the power generation module 102 is less than or equal to the current required electric energy.

[0073] The above technical solution can control the power battery 1041 to provide power to the power component 1042 and the vehicle accessories 1043 when the total power provided by the power generation module 102 is less than or equal to the current required power, thereby increasing the vehicle's mileage and effectively improving the vehicle's economic performance.
[0074] Optionally, Figure 1 As shown, the vehicle controller 101 is used to trigger a first control signal to the power generation module 102 when it is determined that the current power of the power consumption module 104 is less than a preset power threshold; the power generation module 102 is used to provide a first direct current to the DC / DC converter 103 in response to receiving the first control signal; the DC / DC converter 103 is used to convert the first direct current into a second direct current, and transmit the second direct current to the power consumption module 104.
[0075] The vehicle controller 101 can monitor the current power of the power module 104. When it is detected that the current power of the power module 104 is less than a preset power threshold, the vehicle controller 101 can trigger a first control signal to the power generation module 102 to control the power generation module 102 to provide power to the power module 104. The power generation module 102 can convert other forms of energy into power and input it into the DC / DC converter 103. The DC / DC converter 103 can convert the first direct current provided by the power generation module 102 into a second direct current suitable for the power module 104, and charge the power module 104.
[0076] The above technical solution can provide electric energy to the power module 104 in a timely manner, increase the mileage of the vehicle, and thus effectively improve the economic performance of the vehicle.
