I'm building a power storage system this month based around a BMW i3 battery.
This has spent its working life in a climate controlled zone under the car, heated and cooled as required.
The 8 modules are 44V 94ah cells and the published ratings suggest 10ah more storage per module at 25 degrees (centigrade) than at -5 degrees, and that amounts to almost 4kw lost capapcity
I plan to install a heating element (large vivarium heat mat) in this pack before installing it in the garage and setting it on a themostat to keep it above say 15 degrees
This is the most efficient was to store and consume power, so why do i see very little mention of this in these forums??
