We're having some trouble getting any kind of decent charge rate on our Zoe (R90) - rarely above 11kw recently (on 22kw chargers). I've see that wonderful spreadsheet showing expected charge current for temperature and charge status and it leads me to ask an obvious question...
Would I expect the cell temperature change during the charge cycle and is there a way to (positively) influence the battery temperature during charging in low ambient conditions (<10C)?
All the chat appears to focus on how to keep the temperature down but, living in Scotland, for most of the year I want to increase the battery temperature
I know that driving the vehicle will increase the temperature, but there's something counter intuitive about making a long enough journey (or driving like an eejit) prior to charging just to get a higher rate of charge.
I have CanZE (Oh thank you SO MUCH for developing that!) but haven't yet worked out if / how to map or log historical charging rates and cell temperatures - I have a nice list from ChargePlaceScotland of all the charge session I've made on their network and worked out the average rate for each charge, but I can't cross refer that to SOC and cell temperature to see if there's a pattern emerging.
The importance of this comes with trying to use the vehicle in the real world where I might not want to spend 3 hours waiting for the car to charge enough, or hope that it really does charge more quickly if I've given the battery a cuddle first...
Do I have a problem with my Zoe or do I have to live with this as one of the realities of EV ownership?
Of course I can always charge it slowly overnight at home, but if I am not at home, this is not an option.
