    Charging 80 or 100%

    It is highly likely that your pack is not completing the balancing discharge step. These cars only balance the pack at a high state of charge due to the way they balance. They discharge high-voltage cells to match lower ones. This requires a high state of charge so the range of the car isn't...

    Battery life of 120Ah

    Modern EV batteries are lifetime components. Gone are the days of old chemistry and poor BMS software requiring frequent battery replacement. These cars aren't like early prius or Honda Insights. There will of course be manufacturing hiccups like with Bolt but you really don't need to worry...

    Occasional Use Charger @ Level 2?

    The early Clipper Creek ones were dual voltage, the newer Delphi ones are not. Here's an old thread on this. https://www.mybmwi3.com/forum/viewtopic.php?f=10&t=5242

    1700 miles in 48 hours -- 120 Ah BEV...

    I've had zero issues with the heat pump in my 18 and honestly not seen anyone with a heat pump specific failure. There have been compressor issues, but my impression is that's been more on the non heat pump REX models. For me it's been a key part of making shoulder season airport runs possible...

    1700 miles in 48 hours -- 120 Ah BEV...

    I think you underestimate the complexity required to make a normal refrigeration unit act as a heat pump. I see about 4 different shut of valves acting to reverse the flow in the system at ~$150 each. Plus the additional lines, looks like 4 at the same ~$150 each. So that's about $1,200 before...

    Level 2 Charger Recommendations

    ENate hits the big decision, smart or dumb. Do you need it to be WiFi and allow you to control the tariff charging times or are the car's built in timers enough? I had a dumb charger at first, but quickly got frustrated with the car's controls combined with my variable work schedule. I wanted...

    1700 miles in 48 hours -- 120 Ah BEV...

    The heat pump is just like the one in your house. It's an A/C that can swap the condenser and the evaporator to heat or cool the conditioned space. They are insanely efficient, but not as effective in really low temps. I find my 18 uses the heat pump down to about 20f then the resistive heater...

    Glad I Bought The i3 Instead Of A Chevy Bolt

    The Volt is not being recalled, the Bolt is, but yes Samsung makes the i3 packs not LG.

    Maximum charge rate?

    80% is the average first taper on most cars, so you'll see that as the normal advice regarding unplugging and moving down the road. Electrify America even sends a notification to advise drivers they could be paying a whole lot for the same speeds they get at home. Some cars taper much sooner...

    Mystery Steering Noise

    Is it like a popping noise that could be the springs in the strut? Kinds sounds like when a rock gets kicked out from under the tire at full lock? My car is in front of the BMW parts cannon for a noise like I'm describing right now. This time (4th attempt) they are doing the upper strut...

    Software update needed for HV battery capacity check

    This is what will happen on normal gas BMWs when the 12V dies or there is a high drain from something like the lights getting left on. It's called teleservice battery guard and it's not available on the i3 at all. So either that person you talked to has no idea about i3's or they were actually...

    TPMS reset question/problem.

    Glad it helped you out. If your getting a compressor type noise, that’s absolutely not related to the TPMS. A vibration could be from a poor balance. Another thing to check is the front rims clearance to the struts. If your wide rear rims got put on the front they will contact the struts. That...

    Why is the roof black?

    I wasn't saying the battery cools the cabin. I was saying heat pumps are generally more efficient at cooling than heating do the thermal operating range of the refrigerant. The i3's heat pump is effective at heating down to 14f, but I notice the resistive heater starting to come on around 22f...

    Auxilliary Heater

    I agree Aux heat makes me think resistive heater. The heat pump was standard until model year 2019 for the BEV in the US and never installed on the REx due to space constraints with the REx equipment. Now, sadly it is an option and I think a rather unpopular one so far due in part no doubt to...

    Why is the roof black?

    To echo comments here. The roof is just clear coated CFRP. I'd imagine they made the choice for both a bit of weight savings (all be it very minor) and styling. I love the roof and the fact its literal cut-offs from the layup of the rest of the car. If you wanted you could wrap it in a silver...

    Regen and creep operation?!

    94Ah driver here. The last diode of the regen indicator does not light until you just barely press the brake pedal. Just the throttle pedal will bring the car to a stop, but it's not the full regen the car is capable of. I'm not sure at what point the ABS also slows the car with the friction...

    TPMS reset question/problem.

    Well, for anyone reading this later on in life and having the same issue. Try letting the car go fully to sleep, like overnight. Then do the reset right before you head for the highway. I did some reading on newTis.org. and it said the system is looking for 9 minutes above 20 Km per hour. I feel...

    DCFC Level 3 charging not reliable

    The local Harley dealer near me just put in one of those KeyWatt by ies 24 Kw chargers in and it wouldn't charge my car either. Chargepoint was no help, and the Harley folks were adamant that it was for the general public to use, but didn't have a livewire bike to test it with yet. Same symptoms...

    TPMS reset question/problem.

    DId the winter tire swap on my car today. This time the Tire Pressure reset seemed to take forever and now when it finally completed it's not showing the pressures in the iDrive. It's saying the system is active and all four wheels turned green, just no pressures, only the double dashes next to...

    Giga vs. Tera - Dash Material

    While we are talking about interior fit and finish. Are there any other differences in the worlds beyond materials? I read on the worldwide FB page that the Deka doesn't have any of the courtesy lights under the dash or in the back seats. I like the aesthetic of the dark cloth with the blue...
