Truma fuel cell system

European RV supplier Truma is launching its VeGA fuel cell system at the Caravan Salon 2012 show in Düsseldorf, Germany, set to run Saturday (Aug. 25) to Sept. 2.

Fuel Cell Today reported that the VeGA fuel cell system guarantees a permanent, self-sufficient power supply completely independent of electricity. It runs on liquid gas (propane and/or butane), both readily available and inexpensive.

“We have tested the system intensively for several years and have carried out extensive field tests with around 200 devices both internally and also in cooperation with end customers and vehicle manufacturers,” explains Andreas Schiegl, head of the fuel cell system product center at Truma. “Also, TÜV Süd has tested and certified the product and the entire manufacturing process.”

The VeGA keeps the battery charged to cover the auxiliary power demand on the vehicle – sufficient to have several appliances such as a TV, fridge, lights or heater operating simultaneously. A standard 11 kilogram gas cylinder is sufficient for the fuel cell to produce 28 kw of energy, enough for several days to weeks depending on energy consumption rate.

The fuel cell system works automatically and can run round the clock. Once the supply battery undercuts a certain charging level, the VeGA is automatically activated and charges the battery. The higher charging current and the optimized battery charging technology ensure that the charging process is short and efficient.

Once the batteries are charged, the VeGA returns to the stand-by mode. Alternatively, the fuel cell system can also be operated manually. A color touch screen displays all the relevant data, such as operating mode, battery voltage, charging current or service intervals.
