摘要（英）：

The invention discloses a vehicle air conditioning system electric heating power supply and method. The power supply system comprises a control power supply circuit, a current limit control circuit, a main power supply circuit, a temperature control switch and a PTC heater, wherein the current limit control circuit heats the PTC heater when the temperature switch is at a first state; and the main power supply circuit heats the PTC heater when the temperature switch is at a second state The power supply system for the vehicle air conditioning electric heating can effectively solve a problem of low-resistance power supply upon a PTC cold condition, so stability and safety of the power supply system for the vehicle air conditioning electric heating can be guaranteed.
