I'd like to see a "Ready By" feature that also takes into account electricity pricing tiers and battery SOC. I see two scenarios: 1) Daily/commuter charging that leverages off-peak for saving money and reducing demand on the grid, and also doesn't keep the battery full longer than necessary (although this isn't really a problem I've heard). 2) Long trip charging where you don't want the car sitting at Range full for any longer than necessary, and also want to leverage off-peak periods. Here's how I've imagined them working: 1. You tell the car when the off-peak periods are. I think 4 params would be sufficient: a. weekday off-peak start time b. weekday off-peak end time c. weekend off-peak start time d. weekend off-peak end time I know these change with the seasons, but you will just have to reset these twice a year, not a big deal. 2. You set the maximum amperage you can actually draw at this location, unless you've charged here before the and car remembers and OVMS has access to that information. 3. For the commuter version, you then set the time you leave each weekday morning - the Ready-By time. The car starts charging as late in the off-peak period as possible that finishes either by the end of the off-peak period or by the time you're leaving. We may want to have it finish a 45 minutes earlier to enable battery balancing. We use the SOC and max amperage draw to figure out when to start. If we need to start before the off-peak to make the Ready-By time, we do that - better to spend more than not have a full battery the next day. 4. For the long-trip version, you set also set the Ready-By time, but this should include date and time. You might be staying longer than a day and/or only have access to 110 volt charging. The long-trip version does Range mode charging. Here's a proposal for the logic: a. If the Ready-By is during an off-peak period, we start as late as possible to finish on time. If that start isn't during the off-peak time, we see if there's an earlier off-peak period in which we can start, stop when that off-peak ends, then resume during the last off-peak period. If there is no earlier off-peak time, then we start when we need to start to finish on time. b. If the Ready-By is outside an off-peak period, then we first look to see if there's an off-peak period before the Ready-By. If there is, we charge to Standard Mode full by the end of that off-peak period, and then start again as late as possible that still finishes the Range charge by the Ready-By (regardless of peak periods). If this won't get us ready by the Ready-By, then look for an earlier off-peak time to do some charging. If there is no earlier off-peak time then we just start charging so that we'll finish by the Ready-by. This will at least make maximum use of the off-peak period we do have plus not have the car Range full for longer than we need. I know this is pretty complicated. It would be simpler to ignore the tiered pricing and just have the car ready by the Ready-By date/time in whichever mode you want (Standard or Range). And maybe that's the first way this should be implemented. But, for leaving from home, it'd be good to accomodate when you're leaving with getting as much charging done off-peak with not having the battery too full for too long.
