Tischer installs boosters for a constant and battery-friendly charging process
Kreuzwertheim. Not all batteries are the same. Especially not in caravanning, where two very different types are installed. A distinction is made between the starter battery in the engine compartment and the supply or body battery in the living area. Both can be charged via the alternator. However, since the introduction of Euro 5 diesel vehicles in 2015, there has been the problem that the alternator automatically switches to idle to save fuel when the starter battery is fully charged. The charging process of the body battery is therefore usually interrupted after around 15 minutes and remains unfinished. Tischer is now providing a remedy with its set-down cabins by using a loading booster. This gives the camper independence from external charging stations and allows the power of the alternator to be fully utilized.
Full charge ahead
Heating, refrigerator, water pump – the list of devices that need to be supplied with electricity in caravans and motorhomes is long. In contrast to the starter battery, which has to provide a high number of amperes in the short term to start the vehicle, the supply battery is characterized by a so-called deep cycle. This means that the battery must supply constant power over a longer period of time. Tischer uses AGM batteries for this purpose, which are lightweight, low-maintenance, leak-proof and robust against charge extraction. The latter means that they can release up to 40 percent of their capacity before they need a charge. In the near future, however, Tischer is also considering the use of lithium-ion batteries, which can even deliver 90 percent of their charge.
Always under power thanks to charging booster
The charging process can be carried out not only stationary, but also on the move. However, the aforementioned automatic idling function of the alternator and thin cables that cause the voltage to drop below 14 volts prove to be an obstacle. Thanks to the new charging booster from Tischer, however, the voltage of the starter battery remains at a constant level of 14.7 volts throughout the journey. The booster also ensures that the IUOU charging characteristic is maintained and the supply battery is therefore charged gently. On the hardware side, Tischer achieves this effect using a device combination consisting of a 20 ampere charger, the 30 ampere charging booster and a 15 ampere solar regulator. For this combination, the pick-up experts install an additional high-current socket with 25 square millimeter cables so that the flow of electricity is not impeded by bottlenecks. These lifelines are supervised by a 50 amp fuse, which is installed in a watertight manner.
Fully automatically and unnoticed by the driver, the alternator continues to charge the supply battery – regardless of the different power plugs around the world. A convenient detail that can be a decisive factor for globetrotters and globetrotters. This way, the batteries in the motorhome are fully charged immediately after arrival and the stationary socket at the campsite has a break. For the camper, the vacation begins in peace and quiet and he can devote himself to recharging his own “batteries” on the deck chair.
