In Conductix-Wampfler Hybrid E-RTG (Rubber Tired Gantry) crane systems the battery pack is the main power supply and connected through a very efficient DC/DC converter to the DC bus of RTG drive.

Regenerated energy from the motors during e.g. lowering a container can be recovered and is fed back to the battery system through the DC/DC converter. If the battery system reaches its low level State of Charge (SOC) the small size genset will be started to recharge the battery system until it attains its upper level of SOC again.
