Volvo’s Battery-Powered Cooler

Volvo Trucks North America has introduced a battery-powered parking cooler as a factory-installed option for its VNM 630, VNL 630, VNL 670, VNL 730, and VNL 780 sleeper models. It allows drivers to keep the cab and sleeper comfortable without idling the engine, providing an environmentally friendly and efficient solution for maintaining comfort while parked.

​With regulations varying from state to state – and even city to city – the parking cooler eliminates the guessing game when it comes to anti-idling rules while maximizing driver comfort, lowering fuel costs, and reducing emissions, says Volvo.

Power comes from the combined energy of the truck’s starting batteries paired with four AGM deep-cycle batteries located in the in-frame battery box.

The Volvo parking cooler is TMC-approved and rated to keep the sleeper comfortable at 74 F for up to 10 hours, even during the heat of the day. The system is said to be ideal for long-haul drivers who run their trucks at least six hours, then park for their required break. Smart energy management software is also included and protects the engine’s starting batteries from being run down.

The cooler is operated by an automatic thermostat that controls both the air conditioning and heat if the truck is equipped with the optional cab parking heater. The thermostat allows the driver to simply set one temperature plus the fan speed to maintain optimal cab comfort. And, as a factory-installed option, the cooler is fully integrated with the sleeper duct work. For service and maintenance, it’s easily accessible through convenient service panels.

The battery-powered cooler is covered by a three-year warranty.
