Securing the cargo in motorhome

Whoever wants to go always full e-bike batteries, must economize the energy. New mobile chargers are highly efficient and easy to install. Promobil shows what is important.

Without question E-bikes are a nice touch. Many motorhome thus expand locally its radius of action considerably. Standing in beautiful surroundings preferable must find the 230-volt mains-independent way to recharge the batteries Radl after day tour again. Just before this problem was also Promobil reader Jochen Hörnle, who in the past first so made do to drag for dinner the restaurant e-bike battery charger together and ask for a matching socket.

That was certainly not always easy – abroad, for example, where e-bikes are not as common as in this country and where in addition to those of understanding also communication problems. For Hörnle was therefore clear that an individual solution must be found for its Hymer B-Class.

12-volt electrical system or additional travel charger?

Generally, there are two possibilities: first, the battery-charging via the included 230-volt charger that goes through an inverter. It is supplied from the 12-volt electrical system. Or, secondly, recharging with a special travel charger that from the 12-volt battery produces directly the necessary charging voltage of 36 volts and more.

The Travel Charger for 169 euros Bosch has recently such a charger in the program, which is tailored specifically to the e-bikes with the hotel’s own components. But there are also non-brand chargers bound, for example, the Power Butler produced in Wilhelmshaven. The costs depending on the model between 100 and 200 euros and is – says CEO Georg Deep – “with almost all types of batteries compatible” and can even invite up to two bike batteries simultaneously.
The matching terminals on the battery pack can be realized with adapter plugs.

The variety is great, from the Bosch standard plug old and new on Yamaha charging terminals up to Rosenberger connector with solenoid connector and data transfer contacts. Georg deep stresses that customers can even send a picture of charging plug and nameplate of the 230-volt charger in doubt, after which the 12-volt charging station is configured.

Just as varied as the terminals, the e-bike batteries are even older systems that use 26 V, 36 V and current with voltages above 50 V are on the rise. Also a good universal charger determines not only the correct charging current, but also recognizes the battery capacity.
