A/C Electric Compressor ACCM

NOTE: Refer to Specifications in the Climate Control System article for the appropriate refrigerant and refrigerant oil. The refrigerant and refrigerant oil listed are the only oils to be used as the refrigerant system lubricant for electric vehicles. Addition of any oil other than the referred to oils for the refrigerant system will damage the A/C electric compressor and contaminate the refrigerant system. Use the oil adding procedure specified for this vehicle when installing a new electric compressor. Refer to Refrigerant Oil Adding procedure in the Climate Control System article.

NOTE: For HEV and PHEV vehicles, the A/C electric compressor may run and airflow may be felt when the climate control is off to provide cooling to the battery.

For the appropriate refrigerant and refrigerant oil Refer to: Specifications . . The hybrid vehicle is equipped with an A/C electric compressor and an ACCM, which are integral to each other. They cannot be removed or serviced separately. The ACCM has both low voltage and high voltage connections. The ACCM requires a 12 volt low voltage system operating voltage between 9 and 16 volts. The ACCM also requires high voltage system range between 140 and 350 volts. The A/C electric compressor allows for A/C operation to continue even when the vehicle is in full electric mode, when battery voltage allows. When the ACCM receives the A/C request message, it engages the A/C electric compressor. Instead of cycling ON and OFF like a traditional A/C compressor, the A/C electric compressor speeds up or slows down as required the A/C electric compressor may run and airflow may be felt when the climate control is off to provide cooling to the battery.

For more ACCM and A/C electric compressor information Refer to: Climate Control System - Vehicles With: Dual Automatic Temperature Control (DATC)/Electronic Automatic Temperature Control (EATC) . The A/C electric compressor allows for A/C operation to continue even when the vehicle is in full electric mode and the gasoline engine is not running.
