I read that having a 50% charge on the traction battery is the best state of charge for long battery life. So I've decided to set up a two stage charging scheme using Delayed- Rate & Departure charging. I set it up so that after commuting home with no charge remaining, I charge for two hours and complete charging just before departure the next day. This will give me some charge if I want to run an unexpected errand in the evening as well as use power from my solar panels in late afternoon. Finishing off the charge just before departure should serve to warm the battery up before my commute. Any thoughts on this scheme.
