While the truck runs, the alternator charges the lithium bank through a controlled DC-to-DC charger. Parked, that stored energy runs the compressor, fans and cabin power — no main engine required.
Alternator — generates power while the truck is driven.
Controlled DC-to-DC charger — regulates current into the battery bank.
Lithium battery bank — stores energy for overnight use.
Electric APU compressor — cools the sleeper using stored battery power.
