    Few questions after a few weeks of ownership

    1. What mode are you running the HVAC system? If it's in AUTO, it should sense and adjust the fan and the a/c setting to keep the windshield clear. Also, you might try bumping up the fan speed somewhat. It can stay in AUTO, while the fan adjustment is more of an aggressiveness setting and...

    What does your "miles to empty" show when full?

    The range estimates are to the indicated zero point. And, the range to 'empty' is constantly being adjusted on a rolling average of the last 18-miles of use. So, unless you' are always driving the same route under the same conditions, it will often change. Say your trip starts out on country...

    My i3 is Dead

    Almost everything in modern BMW vehicles (and some others, as well) is controlled via computers and that includes the lights, fans, and nearly every module in the vehicle. When you shut down, the computer sends serial data messages out the CANBUS to tell they to go into sleep mode. If there's...

    can I charge the 12v battery through the 12 v socket?

    To get into the vehicle, you may have to resort to actually using the key. To get access to the key slot in the driver's door, you have to use the key in a small slot underneath the handle to pry out the plastic cover, which should pop out, gaining access to the actual key slot. Once you're in...

    How to deactivate acoustic pedestrian protection?

    In theory, should you ever have an accident with a pedestrian, or maybe even another car in a parking lot, you'd be opening yourself up to a big lawsuit as you would have defeated a now required safety component of the vehicle. I doubt it's on the states' inspection list, but it likely will be...

    New Owner Charging Questions

    CCS charging was optional in 2014, so first, you'd want to verify yours has it. If yours does, you can use any CCS or EVSE unit (DC fast charging or level 1-2 acv charging from an EVSE). The CCS plug is essentially the level 1 plug with an additional two pins below that provide the DCV input...

    I’m looking to buy R19 i3 snow tires

    I have a set, but shipping could be expensive from NH. Someone local that could pick them up would be preferred. They probably don't have much more than 8K miles on them, but are original from 2014, so at about the recommended service life. But, if you look at the price of the wheel, it's...

    Which versions of the AC compressor have people had failures with?

    You can't open up the refrigerant lines without first recovering all of the refrigerant. Once you've made any changes, you then have to pull a vacuum, and refill the system. At least in the USA, it's illegal to vent the refrigerant into the atmosphere, and it's not a good idea anywhere...

    20" rims

    As rubber ages, it gets harder. As rubber gets colder, it gets harder. So, the worst combination would be to have older tires (tread depth does matter, but not if it can't conform to the road surface) in cold weather. The stopping and cornering grip is measurably lower. So, if you drive when...

    What does your "miles to empty" show when full?

    FWIW, on the REx, any heating for the cabin is via resistance heaters which can suck up a lot of energy...1w out of the battery = 1w of heating. On the BEV that has a heat pump, 1w out of the battery can produce as much as 3w of heat, so it's lots more efficient when heating unless it is too...

    Ultrafast Public Charging for i3

    Two parts to fast charging: - on ACV, the ac-dc conversion is in the vehicle, and that limits how fast you can charge - on DCV, the controller in the vehicle limits how fast you can charge As has been stated, in many markets, the i3 is limited to 7400W on ACV, and 50Kw on DCV...more available...

    What does your "miles to empty" show when full?

    Once the vehicle is up to speed on the level, extra weight isn't a huge hit on efficiency, but climbing a grade, that weight becomes a factor. Going down, OTOH, you'll have more inertia, and be able to regenerate a little stronger with more weight in the vehicle. Your biggest potential range...

    What does your "miles to empty" show when full?

    Probably your worst situation is lots of short trips where the car is parked in the sun, and you have the a/c set to a generally comfortable range. Well, on the REx, in the cold, heating is all via resistance heat, which is a lot less efficient than the cooling or heat pump on the BEV. It...

    Uk charge point registration and over night charging

    Given 4K per year, you may not need a larger EVSE other than the one provided unless, you do get the battery low, and want to go out again after a fairly short time interval. I might consider one if it would need to be outside with no cover...while the included unit is water resistant, it's not...

    Tesla Charging stations

    At a supercharger, there's digital communications between the car and the system, so that they can determine if the car is authorized, and if they need to charge them for the electricity. But, any Tesla vehicle (assuming their account info is correct) should be able to plug in and charge. The...

    Welcome to the BMW i3 Forum

    The seats are fine for the duration of the existing battery charge, at least for me. So, given more padding means more weight, and the design as a city car...I think it's a good compromise. That's one reason I didn't go for the REx, as stopping once an hour to recharge or refill and the...

    Tesla Charging stations

    IOW, Tesla makes adapters for TESLA cars to be able to charge elsewhere, but Tesla (currently) does not allow ANY other brand to charge at their superchargers. Way back when, that was discussed, but nothing came of it. So, for DC charging, there are three protocols, with different plugs, and...

    Chargepoint Questions

    As was stated earlier, at least in the USA, the breaker is to protect the wiring, not the device plugged into it. Same idea when you plug in a 100W lamp into a circuit capable of 15A (nominally 15*120=1800W). Using less of the available power is normal, and perfectly fine.

    Ultrafast Public Charging for i3

    In the USA, maximum CCS rate is 50Kwhr. Level 2, 7400W, or nominally somewhere in the 30-32A range, depending on voltage supplied.

    Chargepoint Questions

    Fine point, but the internal charging of the i3 is limited to 7400W, two 3700W devices. My soon to be i3 replacement X5 45e uses one of these, for a maximum of 3700W. So, while the EVSE sends out a signal that says how many amps (to protect the wiring to it) it has, how much power is actually...
