BEV Charging in the cold weather.

[Colin Lambert]

Good Morning all,
Just wondered how the cold weather is affecting the charging/mileage on the older eNiros. (2021 4+)
Last summer on a full charge I was getting around 313 miles on the very odd occasion I needed a full charge.
But now, charging only to 90% I am getting 231miles (=256 if I was to charge to 100%.)
This is my first BEV so not aware of how the temperature affects the charge, other than cold is not conducive to charging) I understand there is a 'sweetspot' temp of around 61F (16c).
We haven't been over 47f (8c) for weeks now.
Any comments, most welcome.
Thanks.
Colin.
