Show the main battery temperature, perhaps on the charging screen.
During winter there can be complaints and confusion around supercharging being slow. The normal cause is a cold battery pack which limits charging. If you could display the battery temperature either as part of the car status page (the one with the tire pressure) or on the charging screen, it would be much easier to advise and explain why supercharging is slower than normal. The driver would also then have a clear indication. This information is already present in the canbus as far as I know so it should be easy to display it somewhere on one of the screens.
A bonus would be a popup message when you charge with a cold battery. Something like “Charging is limited due to cold battery, but may improve as the battery warms up”. There is a similar popup when advised to charge immediately after parking at low SOC. What I suggest here is a similar message when the charging begins but the BMS measures a temperature below a certain threshold in the battery pack.
Moderator: There are third-party products that can tap into the can bus and display the battery temperatures and a lot more internal details for those that want a solution today.
