Electric Power Distribution Control

SYSTEM

AUTOMATIC AIR CONDITIONING SYSTEM : Electric Power Distribution Control


DESCRIPTION

- Based on the vehicle status, battery remaining energy, and other factors, VCM calculates the electrical power needed to operate the A/C system, and sends this value to the A/C auto amp. via EV CAN communication.
- Based on the ambient sensor signal, inlet position, outlet position, target air mix door position, and other information, the A/C auto amp. calculates the electrical power used by the electric compressor and PTC element heater. If the total exceeds the electric power consumption permitted by the VCM, then the operating rate of the electric compressor and PTC element heater are reduced to lower the power consumption.






WARM-UP AND COOL-DOWN CONTROL

- For the first 10 minutes after the power switch is turned ON, heating/cooling operation at maximum capacity is possible based on a judgment by the A/C auto amp. (however this does not occur in ECO mode).
