New Prime owner here. I hope the forum can help me with something I can't seem to find in the manuals or via searching online thus far. When the car indicates that the EV battery is 'fully charged' via all 3 blue lights on the dash on at end of charging or via the instrument display on the dash showing "100%" and 0 time to fully charged, is the battery at true 100% capacity charge or is the Toyota software telling me 100% at a lower actual state of charge to protect battery life? I've been told by multiple sources that charging batteries up to full on the regular can degrade their capacity and I'm wondering if a safeguard against that has been built into the car or if I need to make sure I stop charging at 80-90% full myself. Thanks.
it is toyota telling you it's charged as much as they allow. they have always had a buffer at the top and bottom since they started building prius.
Ah, so not true state of charge of the battery but "percentage of Toyota's allowable capacity within the full size of the battery"? That makes sense. I know my Gen2 was like that but haven't been keeping up with the details of new cars since then until now. Thanks
As @bisco said, there's a definite buffer built in. You don't need to worry about anything. Also if you have a 240v receptacle near your Prime, you can use your Toyota OE EVSE unit for quicker 2:28 minute charging. Rob43
Note the 100% on the dash is just a representation of usable capacity. The aftermarket gauge on the right shows actual capacity. The system is designed to always prevent overcharge and never allow deep discharge.
If you mean what is on the right side of the image, that is not part of the Prius Prime's instrument cluster but a display (likely on a smartphone) of an aftermarket app that works with an OBDII dongle (where mechanics plug in to check various diagnostics on any modern car) and displays information we would never otherwise see.
This is the view out the windshield, probably from a dash cam. This is another camera aimed at the car's dash: This is a recording from Hybrid Assistant running on an Android phone connected to the car's OBDII port. John puts them together with a video editor so we can see what's happening with all three simultaneously.
