What counts as a charge?

[torrent99]

Bigger battery is always a good solution, solving several problems in one.

As a matter of interest I did a tot up yesterday of the benefit of fridge storage at weekends, allowing for cooling time for the entire content at the outset, full warm up and charge time at the end on each occasion, and assuming no thermal stress effects.

Based on a bike doing around 20/25 miles range and a normal capacity loss of around 20% per annum, I calculated that the range would be extended at the end of the first year by around 0.9 miles at best if the temperature of the fridge really was at around zero degrees C constant. Since it would much more likely be around 5 degrees C average with some thermal stress inevitable the range gain would probably be more like half that. Taking that into account and all the hassle involved in the cooling and charging procedures, I think it's shown it wouldn't be worthwhile for such a miserly gain.

Oh well at least that's put the question to bed! Thanks for that flecc.

BTW what sort of figure do you usually use for Wh per mile?

Cheers

It's not an expression I usually use Steve, as said before, I tend to be a bit blase about batteries and just use and replace, not worrying about consumption either. My current two bikes when in their original form were both a bit greedy so it wasn't something I'd draw attention to, with the Quando using 24 W/h per mile and sometimes more.

A bit better now though since converted it into the Q bike, with as little as 10 W/h per mile, depending on my input, but my performance oriented T bike is not for the green minded using 18 W/h per mile.

Compared with cars though, it's all peanuts.

Thanks for that. Yes peanuts in comparison to cars (& in money terms the tube too).
