Re: Upgrade battery.

so if they software issue would be resolved somehow - You could upgrade your 94ah for around 3-6k out of pocket to a 120ah and a 60ah for about 5-10k. I would pay about 5-10k to upgrade my 60ah to 120ah if it was offered. I would even consider the lower end of that range for 60-94ah upgrade. It see...

Re: Question on Installing Level 2 Charger @Home

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 charge 33kwh / 1.4kw = 23.8h for a full charge Yep. My point was 10h / 23.8h is closer to 40-50% than it is to 25% (it's 43% :geek:). So if someone's getting ...

Re: Charging port solenoid

Car won't charge from our BMW home wall charger. I tried resetting the charger at the fuse box, same thing. Used the 13 amp house plug charger, same thing, which leads me to believe the chargers are not at fault but the locking solenoid on the car. With the car locked the charging cable can still b...

Re: I Officially Hate Deer

Managed to miss the first 2 deer but caught the rear end of the 3rd one on the front right corner of the car. Took it to a body shop and came away with an estimate of $7,500. Your butcher is quoting you way too much for deer jerky! :lol: A rather astounding $1,900 just for the LED headlight! In all...

Re: Question on Installing Level 2 Charger @Home

I 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-i...

Re: Question on Brake Pads & Brake Fluid Change

As you mentioned, brake pad life is highly dependent on driving style, even more-so on an EV (or hybrid) because of regenerative braking. 100k miles isn't unreasonable on a set of brake pads in the right conditions. The only way to know where you're at for sure is to measure the pad thickness which ...

Re: Buying a used i3 94 Ah

I agree that you should be fine with the 94ah battery. Looking at it from a worst case scenario: the 70% "warranty threshold" of a 27.2kWh battery pack is 19.04kWh. In order to go 70 miles with that capacity, you'd need to average 3.7mi/kWh. Considering that your climate is pretty close to ideal for...

Re: Help with understanding Range Loss over time

We are working on our ability to do more at the moment, but are leaving the machine learning model to tease our differences between drivers. Thanks Jon! This seems do-able for the machine learning to account for and make a pretty good estimate (especially if you're accounting for localized temperat...

Re: Battery Life Remaining on 2015 i3 w/37k at 17.4 kWh

Is 17.4 kWh capacity considered to be normal degradation after 5 years of moderate use? It seems likely that this is in the realm of "normal". BMW or Samsung are probably the only ones who could answer for sure though. It actually sounds pretty good compared to what I've seen by tracking my car (th...

Re: Front Turn Signals

It's amazing how many people have strong opinions on turn signals. I'll admit I'm one. I feel pretty strongly that turn signals should be amber (not red) and distinct bulbs from the brake lights. Oh, and I also changed to LED bulbs in the front. Plus, I'll bet I'll save a nickel or so in electricity...
