The secret behind thermal management

The heart of the HTW 100 E³, used for maintenance work on the overhead line system, is the innovative battery system. It allows the machine to work electrically on the work site and makes it emission-free and quiet. Particularly in urban environments or tunnels, this is a great benefit. The battery capacity lasts for two six-hour shifts. The operating temperature is crucial for the batteries’ service life. In collaboration with Kreisel Electric, an expert in electromobility, a sophisticated thermal management system was developed for the HTW 100 E³.

At a cell temperature of between -20 °C and +40 °C it is ensured that the batteries generate energy. The optimum operating temperature is between +25 °C and +35 °C. Siegfried Anschuber, Software Developer at Kreisel Electric, explains the system: “The nine batteries are fitted with more than 200 sensors that measure the temperature constantly. The new thermal management allows maintaining a permissible operating temperature by warming or cooling the batteries. As a result, external conditions barely affect us any more. And: When a machine is parked at -20 °C, the next day, the batteries are heated up via the heat pump.” During testing in the Climate Wind Tunnel, these temperature limits were simulated and numerous machine functions were tested.
