APPLICATION GUIDE

Electric APU for semi trucks

An electric auxiliary power unit, or eAPU, supplies battery power while a truck is parked. For sleeper fleets, the starting point is simple: keep drivers comfortable between shifts while reducing engine idling.

Plan around the hours between shifts

Tell us how long your trucks stay parked, the cab equipment you need to power and the temperatures your drivers encounter. Runtime depends on battery capacity, equipment demand and operating conditions. We’ll review the truck and charging setup with you before recommending a configuration.

What should I send when asking about an eAPU?

Send your truck make and model, sleeper configuration, typical parked hours and current battery or APU setup. The product sheet is a useful starting point for a fleet discussion.
