Busworld 2023: Thermal Management in Electric Buses

Gilching, September 27, &#; Whether in electric minibuses or city buses &#; Webasto&#;s High-Voltage Heaters (HVH) convert electrical energy into heat at an efficiency close to 100 percent. At the Busworld Europe exhibition in Brussels from October 7 to 12 (Hall 7, Booth ) the company is exhibiting the latest members of its HVH family that deliver 10 and 12 kilowatts (kW) of heat output respectively. These are the second generation models of the world&#;s first 800-volt heater to enter series production. Together with the new CoolTop 80-e (CT 80-e) electric rooftop air-conditioner, the heating and cooling units form the basis for feel-good temperatures all year round &#; from the driver&#;s cab to the passenger cabin. In conjunction with the intelligent Cronus Smart control unit, Webasto also combines various components from its heating and air-conditioning technology portfolio to create the centrally controllable electric Thermal Management (eTM) system, which keeps both the traction batteries and the passenger cabin at the ideal operating temperature.

Pioneering electric heating
 

The new models allow Webasto to offer efficient electric heating solutions for all conceivable application scenarios. The HVH 100 Compact and the HVH 100 Compact + each offer a heat output of 10 kilowatts. With a height of just 7 centimeters, they are smaller than a DIN A4 sheet of paper and designed to operate at a voltage range of between 250 and 880 volts. Communication takes place via LIN bus, which facilitates the heater&#;s technical integration into the vehicle.

The HVH 100 Compact + models with a heat output of 10 kilowatts and the HVH 120 with an output of 12 kilowatts are also compatible with the CAN-protocol. Their compact housing and flexible connectivity options offer manufacturers many options for easily integrating the units into their vehicles. Thanks to precise and virtually stepless control of the maximum output and target temperature, the High-Voltage Heaters always operate at maximum efficiency.

A special heating layer bonded onto the heat exchanger means that they not only deliver heat at the touch of a button, but can also be safely discharged in a fraction of a second by actively discharging the intermediate circuit capacitors. Webasto&#;s High-Voltage Heaters are protected against cyber attacks in accordance with ISO while functional safety is ensured in accordance with ISO . Webasto specifies a service life of at least 15,000 hours or 15 years for its electric heaters.

Electric air conditioning technology premiere
 

Webasto is exhibiting its first all-electric rooftop air conditioner for small buses: the CoolTop 80-e (CT 80-e) with a cooling capacity of 7.5 kilowatts. The air flow rate of the CT80-e is 2,100 cubic meters of air per hour and the unit optionally features a PEPA-F air filter that removes even the smallest particles from the air, including viruses. This compact powerhouse operates in the high-voltage range between 200 and 430 volts and is designed for temperatures from -20 to +45 degrees Celsius. Webasto uses the latest Ryf coolant to ensure environmentally friendly operation.
