AIR CONDITIONER CONTROL: System Description: Description

In EV, VCM controls the A/C relay so that the air conditioner can operate even in the POWER OFF state. The remote air conditioner and timer air conditioner functions are enabled by this control. When VCM judges a need of air conditioner activation in response to driver operation, timer air conditioner function, or remote air conditioner function, VCM activates M/C relay to start the EV system. VCM also activates the A/C relay to supply power to the A/C 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.
