I drove 800 mi home, a 2017 BMW i3-REx. On the last leg, I drove on battery until the REx took us home. My plan was to put it on an L2 to measure the charge energy in a mostly depleted battery and took a nap: 7 hrs later - 29.5 kWh (higher than estimated 25 kWh at dealer) 12 hours later - 40...

They can use the next door Nissan L2 or any of the local EVSE to throw a charge on the car:: No charge going in - I have to walk away. There may be battery capacity but no way to measure. Charge goes in but disappears. I have to find out if BMW will honor any part of their warranty. Prorate...

I am looking to buy a 2017 i3 REx and was surprised to see the REx started up. It turns out the battery shows no charge yet it obviously cranked over the engine. It ain’t dead but could be close to damaged. In the morning, we will put it on an L2 charger and see if it takes a charge in an hour...

Hi, Has anyone seen someone trying to repurpose a salvage, BMW i3 for battery storage with a solar array? I am reaching out to EVTV Motor Works who have done Tesla battery packs and I understand once looked at BMW i3 batteries. I see two technical approaches: BATTERIES ONLY - pull and/or...

Thank you! We needed the technical details. My wife's car failed on Saturday and we were down to sharing one car, the Tesla. So speed of repair was important. With both BMW and Batteries+ reporting it would not be in Huntsville AL until Friday, it was going to be a long week. Regardless, here...

Hi, The 12V battery finally gave up the ghost and needed replacement. But the $277 price from the local BMW parts department was too much. So I found a 12V substitute, Deka ETX18L, for $136.00, in stock at "The Battery Store" (256-5361845 or Facebook 'TheBatteryStoreHuntsville".) After one...

Hi, Bought in 2016, it would not bluetooth beacon and connect today. So I've order a replacement from Amazon: Vgate iCar Pro Bluetooth 4.0 (BLE) OBD2 Any problems with this unit? Bob Wilson

We had a loud REx traced to the catalytic coming loose. Simple clamp fix. Bob Wilson

Hi, I've ordered a Torklift, trailer light kit that should be here Friday. Anyone have photos or YouTube showing installation? One concern is they want a permanent 12 V source versus a switched 12 V. I was planning to tap the 12 V outlet in the center console. Turns out the 'Imgur' setup just...

I find "My BMW" app is unreliable. Sometimes it works but about half the time, it fails for either unlock or preconditioning. So I'm wondering, can a button on the key fob be reprogrammed to enable conditioning? Since the key fob is independent of servers and cell networks, it should...

Hi, Last night we found the parking lights are remaining on. The Owern's Manual PDF is not terribly helpful. Any best practices to make sure the parking lights are off? BTW, this explains excessive battery SOC loss when the car is parked. Thanks, Bob Wilson

Speculation, could Bimmerlink extract the data from the OBD into a computer to send via WiFi or other, non-BMW provided communications and display? Bob Wilson

Hi, Rotor rust never bothered me but it was a new sound for my girlfriend. Still, it would be nice to get rid of it permanently. Has anyone tried the various aftermarket rotor treatments? Bob Wilson

Excellent posting and data. Now I'm wondering to what extent we might automate data tracking. I have an "iCar II" OBD device and BimmerCode and BimmerLink. Bob Wilson

Thank you! Bob Wilson

Has anyone tried to map the battery Ahr loss vs temperature? We've had exceptionally low temperatures in Dixie, 15F (-10C) and noticed the battery SOC % has significantly gone down overnight. We have a new driver and one hypothesis is failure to turn car off with a second power button press...

I agree but would add it hasn't been until recently that batteries and power electronics began to approach what was needed with steel+aluminum bodies. Yet the traditional maker EVs continue to make less efficient and overweight. They really haven't adopted EV design rules. Bob Wilson

If BMW sent me an e-mail with an offer for a larger capacity battery for my 2014 BMW i3-REx, a reasonable price, I would consider it. But offering those 'boat anchors' was not not going to work. Bob Wilson

If those BMW, plug-in hybrids meet your needs, great. In contrast, our 2017 Prius Prime, 25 mi EV, became 'driveway art.' I would take the BMW i3-REx, a 10-stop car, over the Prius Prime, a 3-stop car. We traded in the Prius Prime for our Tesla Model 3 and got $18.3k. But that was not the reason...

Hi, On Friday I got an e-mail from "BMW of North America <[email protected]>" that has a GIF of several huge, plug-ins that are the antithesis of our BMW i3-REx: Starts with a hand on a J1772 plug 330e driving X3 30e driving X5 45e driving open road Owner of a 2019 Tesla Std Rng Plus Model...
