So it seems lithium batteries or at least some lithium batteries should not be charged below 0°C.
Below 0°C have come. I see frozen water outside.
So what do people do?
And how do you know the temperature of the battery is below/above 0°C?
And does the BMS protect the battery from being charged below 0°C?
You have removeable batteries ok take them inside.
You have non-removeable batteries ok put the scooter inside.
You have non-removeable batteries and is not able to put the scooter inside... now what?
I guess you can make a heating element around the battery and then heat some time before charging.
Or put insulation around the battery.
It seems discharging the battery makes it hot so if the battery have a charge maybe you could power the heating element/heat blower with the battery. That way the battery gets hot both from the inside and outside. But maybe a bit silly to discharge the battery just to recharge it, but if it works it works.
I dont think i have read/seen anything about solutions to this problem for scooters with lithium battery.
I think maybe the solution is a heating element around the battery and then the BMS should have a temperature sensor and only allow the battery to charge when above a certain temperature.
So you just connector the charger to the socket and if to cold the heating starts until temperature is ok and then the charger starts.
That way you dont have to look at the temperature and start the heather manually and return later to start the charger.
But i dont think i have seen any scooters with battery heather.
I guess the battery heather could be inside the battery as well as outside.
If inside the battery maybe its more effective and not so much heat will go to waste.
Or maybe have the heating element connected to a AC socket and then the charger starts when the temperature is good.
Or maybe not so good solution ... have a timer so when the heather have been on for a set amount of time the AC for the charger is turned on.
I would want to avoid having to manually turn on/off the heating element etc. because then you having to come back multiple times and this gets annoying.
