I bought my FFE a couple of weeks ago and this is my first post. Thanks to all for the useful posts over the years. I wish I had found this site before buying the car!
At the moment I'm getting by quite well with the included 120v charger which easily completes overnight. In April I will switch to PG&E's EA tariff and to get the best rates I will probably need a 240v charger.
Because I have modest energy demand (~20 miles per day) and I feel I'll get the more value out of the car the longer the battery survives, I believe the ideal charging system would have modes to:
1) minimize the charging rate such that charging would complete within the off-peak charging period (perhaps with a 1kw minimum) ("low heat mode")
2) if full charge cannot be achieved in the off-peak charging period I would be willing to cease charging at the end of off-peak (basically, if the following day I only need 30% of charge why pay higher rates to charge to 100%? I would be happy with 60%) ("cheap mode")
3) charge to less than 100% to improve battery longevity ("part-fill mode")
4) charge at the highest possible power ("fast mode")
Anyone else see value in these objectives?
Of course my #1 objective is that the charging algorithm is 100% predictable and reliable...
