The vehicle's original 24-volt power supply system cannot directly meet the working requirements of the high-voltage electric air-conditioning compressor. The vehicle's built-in 24-volt generator itself cannot meet the normal working electricity of the vehicle's own electrical equipment. At the same time, it supplies power to the on-board high-power air-conditioner and the on-board high-power external equipment. Therefore, it is considered to design a vehicle-mounted air-conditioning and power supply and distribution integrated system to provide a high-temperature and high-power air-conditioning solution while solving the vehicle's high-power external power supply needs.

[0023] The present invention provides a vehicle-mounted high-power air conditioner power supply system and method, which are described below respectively.

[0024] Figure 1 A schematic diagram of an embodiment of a vehicle-mounted high-power air-conditioning power supply system provided by the present invention, Figure 2A power supply schematic diagram of an embodiment of a vehicle-mounted high-power air conditioning power supply system provided by the present invention and Figure 3 The vehicle power distribution schematic diagram of an embodiment of the vehicle-mounted high-power air-conditioning power supply system provided by the present invention includes: The first air conditioning system 101 is mechanically connected to the engine 102 and is used to drive its own mechanical compressor to work through the rotational motion of the engine 102; The engine 102 is mechanically connected to the first generator 106 and the second generator 103, respectively, and is used to receive the driving power control command, control the operation of the engine 102 based on the driving power control command, and drive the first generator 106 and the second generator 103 to generate electricity through the operation of the engine 102; A first generator 106 is electrically connected to a vehicle chassis battery; The second generator 103 is electrically connected to the battery 104; The battery 104 is electrically connected to the first input terminal of the AC / DC conversion module 105; A first output terminal of the AC / DC (alternating current-direct current) conversion module 105 is electrically connected to the second air conditioning system 107; The external power supply module 108 is electrically connected to the second input terminal of the AC / DC conversion module 105 and is used to receive the parking power control instruction and supply power to the AC / DC conversion module 105 based on the parking power control instruction.

[0026] It can be further understood that the front refrigeration of the present invention continues to use the original traditional air-conditioning system of the vehicle, and adds a top-mounted electric compression air-conditioning system on this basis. The traditional air-conditioning works normally when driving, and the electric compression power adopts the 28V low-voltage DC generator of the front wheel system of the engine 102 to generate electricity. The DC low-voltage electric energy generated by the generator is converted into a 400V DC high-voltage power supply through a distribution device to supply the vehicle-mounted electric air-conditioning system.

The design scheme is to add a front wheel train generator to the original vehicle engine 102 end, and the generator supplies power to the electric air conditioning system after conversion by the power distribution device. When the city power is connected to the (220V, 60HZ) power distribution system when the car is parked, the air conditioner and upper equipment can be guaranteed to operate normally even if the engine 102 is not started. The specific design scheme is shown in Table 1: Table 1: Electricity demand plan design table

The power generation power of the upper-mounted power generation system can be reasonably matched and selected according to the power demand of the customer's equipment and the demand for overhead high-temperature air conditioning.
