I have 2 questions for the battery gurus. 1. Plugged in my car last night. Came out this morning to find that the car didn't charge. Only 40% on the battery, so it should have. Thoughts? 2. Today, with only about 40% battery charge, I had limitations on regen AND on max power usage. It was 32 degrees out, but the garage was 42. Why, with much less than a full charge, was it limited? Temperature? Thanks in advance! PS--for those on the fence, DO NOT HESITATE! This car is amazing!
