I thought I was quite clear on this, I was talking about power from the outlet. I stated earlier in the post that I was talking about "from the outlet". The entire post was talking about costs of running the EV (hence the title). I buy the electricity at the rate it comes out of the wall (well actually the rate it enters my house). NOBODY pays for electricity at the rate it comes out of the pack.
When you are talking about the cost of electricity the ONLY thing that matters is how much you draw from the wall, there are too many variables between the outlet and the motor controller for power from the pack to have any meaning. The rest of that particular paragraph was talking about how much electricity cost me per kw, I even related how the cost of my commute went up because of this increase in power required. Personally I don't see how you could have thought I was talking about anything other than the energy requirements from the outlet. However, if it would help you out I'd be happy to include the extra verbage in every single sentence stating what I'm talking about in detail. Victor Tikhonov wrote: >Peter, Please explain then.
