Hej gruppe
I hvilken gruppe finder jeg gode råd om køb af elcykel - er det denne ellers
send mig venligst videre.

Hej Ole

1. Cyklen skal leveres med LiFePO4-akkumulatorer (
http://da.wikipedia.org/wiki/Lithium-jern-fosfat-akkumulator ) og
kompatibel lader - helst A123-Systems, da de regner med mindst 1000 dybe
af/opladninger. Deres test vist pï¿½ hjemmesiden er indtil videre oppe pï¿½
7300 dybe af/opladninger. Accelereret forï¿½ldelse tyder pï¿½ at
A123-Systems akkumulatorer burde holde ladningskapacitet (80%) og lav
indre modstand i ca. 15ï¿½r. LiFePO4-akkumulatorer er langt sikrere end
traditionelle LiIon-akkumulatorer.

It is best treated as braking (which just happens to feed the braking

such as Go-Karts with the Lynch motor - where the energy re-generated

It is actually the battery which is doing the braking, not the

Hej Ole

Glemte lige nogle vigtige detaljer:

Jo stï¿½rre effekt elhjulet kan klare, jo hurtigere kan det bremse.

Jo stï¿½rre effekt elhjulet kan klare, jo mere energi kan indvindes ved
(evt. hï¿½rd) regenerativ bremsning.

Her er lovgivningen om elcykler:

men den forhindrer ikke en dynamovirkning p� h�jere end 250W. Det er der
brug for n�r man bremser relativt h�rdt op. Dog b�r den s� have en eller
