Abstract

The invention provides a controller of an air compression system of an electric passenger car. An air flow sensor, a temperature sensor, an air pressure sensor and an operating switch are all connected with the compressor controller. The compressor controller, a CAN communication interface, a frequency converter and a motor are sequentially connected. An alarm output indicator light is connected with the compressor controller. A compressor head cleaning valve and an air filter cleaning valve are connected to the same compressed air pipeline. The compressed air pipeline is connected with an air filter chamber through the air filter cleaning valve. The compressed air pipeline is connected with a compressor head through the compressor head cleaning valve. The air flow and the air pressure of the air compression system and the temperature of the compressor head are collected through the compressor controller, the operating air pressure and the operating state of a compressor are adjusted in real time, and thus the air compressor is made to operate in the optimal state all the time; and the failure rate of the compressor is decreased, and the service life of the compressor is prolonged.

Description

Technical field [0001] The invention relates to the field of electric vehicle control, in particular to an electric passenger vehicle air compression system controller. Background technique [0002] The air circuit control system of an electric bus is mainly used to control vehicle braking, door opening and closing, etc. As the electric bus cancels the on-board compressor, the compressed air required for the pneumatic circuit mainly comes from the on-board electric air compressor. The sliding vane air compressor is adopted. The working principle is that the air enters the compressor through the suction valve after being filtered by the air filter. The valve can adjust the air supply of the compressor according to the air demand, thereby maintaining a stable working pressure , The adjustment of working pressure is mainly realized by an air pressure switch. When the air pressure reaches the set value of the pressure switch, its switch contacts will be disconnected and the inverter ...
