The 900 is Webasto's heavy duty test solution. With greater voltage, current, and power capability, this system is ideal for testing and emulating energy storage and drivetrain components of large electric and hybrid electric vehicles (HEV), such as buses, trucks and military vehicles. The 900 is deployed worldwide to support the development of fuel cell buses, hybrid locomotives and other HEVs. All Webasto units are equipped with a real-time clock on the system’s control board that enables measurement of Ah and kWh during cycling.
