On your charging menu there are options for low, reduced, and max IIRC. There's a table in your manual that shows the corresponding Amp flow-thru based on your EVSE. Stock EVSE are either 10A or 12A. There's a label in the back to indicate which you've got.Swapsafari wrote: ↑Fri Jan 08, 2021 2:15 pm
... I am using the regular outlet (120V) and the car is taking too long to charge. I would say for keeping it plugged in for about 10 hours, I would see a jump of 20%-25% charge from where it was which seems really slow? Is there any setting in the car that I need to change for it to charge faster on 120? I know under eDrive I saw charge rapidly which is what my car is set on but wanted to know if there are any tricks to faster charging.
Something seems off here. As @eNate said, on L1 max charge (set in idrive) the provided cable should get you much closer to 40-50% charge boost over 10 hours than 25%.Swapsafari wrote: I would say for keeping it plugged in for about 10 hours, I would see a jump of 20%-25% charge from where it was which seems really slow?
If your Level 1 charging speed is set to Low or Reduced and you increase the charging speed to Max, be sure to monitor the temperature of the 120 V receptacle and EVSE inlet plug. If either becomes dangerously hot, the plug and/or receptacle could melt which could be a fire hazard. This could occur if the receptacle is old with possibly weakened or corroded contacts or with loose connections to circuit wiring.
The BMW charger has 12a x 115v = 1380w - meaning 1.4KW - the battery has 30kwh usable the charger is 90% efficient 30/0.9 = 33kwh for a full charge3pete wrote: ↑Fri Jan 08, 2021 9:02 pmI think you struck a nice balance to go with an L2 station even if you're not maxing out the i3's chargers... as long as it meets your needs. Jumping to 240v doubles your charge speed with the only cost being an additional slot in your breaker box and if you have a very long cable run (and a short-ish commute) it can make sense to limit your current pull. 30a wiring gives you the option to upgrade to 24a continuous charge if you find your present situation to be inadequate either through a hardware limited 24a EVSE, or a "smart" EVSE with a maximum-current setting.
