ICU: 500 kW inverter + 70kW integrated charger

With a 70kW integrated charging system, the ICU automatically senses when it is connected to grid voltage, disconnects itself from the drive motor, and then follows your command to initiate controlled charging of any battery bank. The ICU therefore eliminates the need for a charging station in heavy duty traction applications by incorporating the ability to perform Level 3 charging onboard the vehicle. ICU is equipped with powerful and rugged components, capable of delivering the power you need to the drivetrain, as well as delivering outstanding charging times, all in one very rugged IP67 aluminum enclosure.
