900 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 used worldwide to support the development of fuel cell buses, hybrid locomotives and other HEVs.
All Webasto power cycling systems are equipped with a real-time clock on the system’s control board that enables accurate measurement of Ah and kWh during cycling.
