How Does an APU Semi Truck Work?

An Auxiliary Power Unit (APU) Semi Truck is a device that provides power to the semi truck when the main engine is turned off. This type of technology has been around for about 15 years and is becoming increasingly popular with truckers who want to save money on fuel and increase their efficiency.

The APU Semi Truck works by providing an independent power source to the truck’s cab, allowing the driver to run accessories such as refrigerators, air conditioners, or heaters without having to keep the main engine running.

The APU system consists of three main components: a generator, an inverter, and a battery. The generator produces electricity from the fuel used in the semi truck’s main engine.

The inverter then converts this electricity into usable AC power that can be used by the cab’s accessories. Finally, the battery stores any excess energy produced by the generator for later use.

The APU Semi Truck also has several safety features built-in. It comes with an automatic shutoff switch that will turn off all of its components if it detects an overload or over-temperature situation in order to protect itself from damage. Additionally, it has an emergency start system that allows you to start your semi truck even if its battery has died.

An APU Semi Truck can be a great way for truckers to save money on fuel costs and increase their efficiency. Not only does it provide a reliable source of power for essential cab accessories, but it also helps ensure safety with its built-in safety features.

Conclusion:

An APU Semi Truck is a great way for truckers to save money on fuel costs while increasing their efficiency and safety. It works by providing an independent power source to the cab’s accessories while also providing several safety features such as automatic shutoff switches and emergency start systems.
