A friend of mine works with a recycling collection crew in York, UK and they use a variety of pedal powered collection vehicles and also a Bradshaw FB2 EV van like one of these.
It runs on a pack of FLA batteries but is suffering from the cold to the point where it often needs to be pushed back to the depot.
I was wondering what options there might be to keep the pack warm that would be fairly low tech and low cost to do.
How warm would it need to be and when is it most important to keep it warm during the charge cycle given it will not be warmed while in use?
I have suggested adding insulation to keep any heat in while it is out in bad weather.
I will probably go and have a look at it in the new year to see what I could do to help it.
