Re: 100kWh? @itzman
Are you still living in the last century? Battery technology and its controllers is progressing at a very fast pace now there is an incentive. Power density, kWh/kg and life cycle have improved tremendously in the last 5 years. 200mpg equivalent is easily achievable now. One of the main things petrol heads forget is that every time you accelerate in an IC car, all the energy is lost when you brake. In an EV energy lost in braking is recovered for use in the next acceleration.
Battery life is now quoted as 8 years minimum and even then, an end of life battery will have 80-85% capacity. You can then reuse the battery rather than recycle the battery in a power standby system for another decade or 2.
