The invention discloses a control method for a vehicle-mounted 220V inverter with electric quantity protection. The control method comprises the following steps that S1, an engine management system sends vehicle information, start-stop information and engine state information to a vehicle body control module; s2, the vehicle body control module sends an enable signal to control an output command of a 220V inverter according to the power gear, the energy level and the engine state, and the maximum power is output; s3, the 220V inverter judges whether output is allowed or not according to the state of the relay IG2 and an enable signal of the vehicle body control module; s4, after the 220V inverter operates, whether the maximum power allowed to be output by the vehicle body control module is exceeded or not is detected, and a load signal is fed back to the vehicle body control module; and S5, the vehicle body control module receives a load power signal fed back by the 220V inverter, judges whether to send a sta
