A complete guide to specifying, sourcing and reselling battery-powered sleeper-truck parking AC — covering cooling capacity, runtime, install and homologation.
Long-haul drivers must rest in compliance with HOS / EU drive-time regulations, often in summer temperatures of 35-45 °C. Idling the main engine for HVAC burns 3-4 L/h of diesel, accelerates engine wear and is increasingly restricted by anti-idle regulations across the U.S., EU and China.
For typical Class-8 sleeper cabins of 6-9 m³: 2200W is entry-level, 2700W is the global mainstream, and 3500W suits hot-climate fleets in the Middle East, Brazil and Australia. Match cooling capacity to the worst-case ambient temperature in your market.
A 2700W parking AC running on a 4Г—12V/200Ah AGM bank delivers about 8-10 hours of cooling в€’ enough for a regulated rest. Lithium banks extend this by 30-50% with significantly less weight and longer cycle life.
VETHY markets parking AC globally under the CoolDrivePro brand, with split, rooftop and battery-bank-integrated options across 12V and 24V. See our truck-commercial / parking-ac category for full specs.
