AIR CONDITIONER CONTROL: System Description: Description

In EV, VCM controls the A/C relay so that the air conditioner can operate even when power switch is OFF. The Climate Ctrl. Timer (A/C-heater timer), remote climate control (models with 7 inch display) and de-ice control (automatic air conditioning system with heat pump system) functions are enabled by this control.

When VCM recognizes a need for air conditioner activation due to driver operation, Climate Ctrl. Timer function, remote climate control function (models with 7 inch display), or de-ice control function (automatic air conditioning system with heat pump system), VCM activates the A/C relay to supply power to the air conditioning system.

In addition, VCM calculates the power that can be used by the air conditioning system based on the Li-ion battery status and vehicle status and sends it to the A/C auto amp.

When ECO mode is selected, VCM sends the ECO mode signal to the A/C auto amp. to control the air conditioner at a lower rate than normal.
