What is the most efficient way to charge the BMW i8 battery?

I just bought a BMW i8 and I am wondering what is the most efficient way to charge the battery. Should I use a public charging station or is it better to charge at home? Also, how long does it take to fully charge the battery?

In my experience, the most efficient way to charge the BMW i8 battery is to use a public charging station. These stations are specifically designed for electric vehicles and can provide a faster and more reliable charge. However, if you have access to a dedicated home charging station, that can also be a good option.

I would recommend using a public charging station for the fastest and most efficient charge. However, if you are charging at home, make sure to use a Level 2 charger that can provide a higher charging rate, resulting in a quicker full charge.
