https://www.maximizemarketresearch.com/market-report/global-electric-vehicle-range-extender-market/16907/ Electric vehicle range extender, also referred to as auxiliary power unit (APU), is an electric vehicle equipment that provides additional energy for electric vehicle functions and operation other than forward motion. Electric vehicle range extenders are widely found in heavy commercial vehicles and industrial vehicles.

An electric vehicle range extender can deliver power either via single-phase or three-phase systems.
