This is a very nice graph. Do you have a link to the report from which it was extracted ?
I guess I missed the memo that garygid sells his SOC meter. Can you point me to the thread that talks about this in more details? I'd like to learn more. Thanks.gascant wrote:FWIW, I recently bought an SOC meter from garygid.

The road that we use to reach our mountain town (CA-330) seems pretty good for that purpose. When there is not much traffic and the SOC is sufficiently low, it is possible to use ECO mode regen to keep one's speed down with little to no use of the brake pedal. You'll have to come visit!

Regen efficiency = (5 clicks/7 clicks) = ~73% +- 7%.
