Pedelec-Ladegerät für Wohnmobile (E-Bike Battery Charger for Winnebago Warriors)
[DEUTSCH]
[DEUTSCH]
Immer mehr Wohnmobilisten haben den Motorroller gegen Pedelecs ausgetauscht. Gut so! Aber das Ladegerät aus dem Haus im Wohnmobil an einem Wechselrichter zu betreiben ist vom Wirkungsgrad betrachtet Unfug, aber leider z.Z. notwendig. Wie wär´s mit einem Ladegerät, das 1. sowohl an 230V Netzspannung als auch an 12V/24V-Akkuspannung betrieben werden könnte und 2. für mindestens 2 Pedelec-Akkus und mit einstellbarer Li-Akkuspannung genutzt werden könnte?

During the past few years, more and more camper and mobile home owners have been taking electric bicycles along for the ride. The electric bike is quickly becoming the short-distance vehicle of choice for travelers interested in venturing out of their mobile abodes for quick trips to nearby shops and town centers. It’s a pretty convenient alternative to driving a gas-guzzling Winnebago a few miles for just a few camping provisions. Just hop on the electric bike and take a spin! That sounds great, except for one problem: electric bikes batteries must be recharged. Wouldn’t it be nice to have a battery charger that could run from the mains supply, but also operate directly from a 12/24-V car battery in an efficient manner—that is, without DC/AC converter? Such a device should be able to recharge two bikes at once and have an adjustable output voltage.

In Elektuur januari 2005 is een zelfbouwconverter verschenen die kwaliteiten heeft die zijn vereist:
uitgang 0-100V DC ; 0-5A DC
beide regelbaar
ingang converter 35V(max) heeft max output 500W
Dit kan worden bekomen door transfo 500W indien ingang 220VAC
of met een boost converter indien op 12V batterij

Here is the start of the list of e-bikes and there charge requirements:
ANTEC / EASYS DC 43.8 V / 1.8 A
Sparta ION DC 34 V / 3.4 A const.

Hi,
I'm a plane model enthusiast for many years. We use versatile chargers which are able to charge different battery chemistry (lithium, NiMh, Lead acid). Those chargers are mostly designed to work on 12V dc supply and can source up to 200W for certain models. And when you want to use it at home or on a mains supply, a computer power supply does the converting job with plenty of power for a few bucks.
I think it could easily do what you are looking for...

I think this will be a very useful project.
Camper van + electric bicycle = better holidays.
Also useful for charging electric bicycles from home solar systems, which might have 12 or 24 volt accus for storage.
I am only an electronics hobbyist, not professional. Have we got some starter ideas ?
I don't have a camper van, but I am interested in charging 36 volt bike batteries from a small solar panel at home.
