DC/DC Converter Based Auxiliary Battery Charging Solutions

Most Class 8 tractors have a much larger battery bank than a typical liftgate system and they serve as an excellent source of supplemental power for a liftgate system. When a tractor is connected to a trailer and utilizes a liftgate charging cable, also known as a stinger cord/cable and socket (either single or dual pole), to charge the liftgate batteries, this is considered the traditional method for supplying power to the liftgate battery banks. Sometimes this is not enough power to maintain the liftgate battery system and so trailers are susceptible to being unable to complete a trip or stuck with the gate in the down position.This can be frustrating when the batteries are not adequately charged.
