Re: bmw i3 important question

But, already my range is up to 140 miles, instead of the normal 124-126 I have been getting and it is "cold" here, 47F! :) That’s great news and SO glad it’s headed in the right direction... I’ve never used or experienced a REx fitted i3 so have no idea of the idiosyncrasies of this version - but c...

Re: bmw i3 important question

Thanks Fordy and Art. I let my i3S "run out" of battery and the REX kick on yesterday afternoon. I plugged my car into my BMW Level II wall charger. Someone suggested this on the Facebook i3 Page. They said to charge on Level II, not the provided Level I and then allow the car to remain on the charg...

Re: bmw i3 important question

I’m still a bit astounded that there can be such a difference between the range we seem to get from our i3 120Ah - and what others in places that would appear to be more suited to EV driving - do from theirs. The bottom line seems to be low driving efficiency and why Deutsch100's 2.8 mi/kWh is so m...

Clearly we’re very fortunate, but I still don’t think we are that unusual in getting that ...

Re: Estimated full range is always LOW

Many, many trips show that I got 2.5 to 2.9 kWh per mile :( I drive so slow, ALWAYS accelerate slowly and never go fast! Today I drove for 30 mins, speeds under 45mph and mostly flat roads. I was in EcoPro the entire trip and I got 2.8 kWh per mile. I assume you meant to write "mile per kWh" rather...

Re: bmw i3 important question

I too cannot imagine I have had two "bad" i3s. I know the REX adds weight, the i3S has more hp and torque and the wheels are bigger and wider....but still I should be getting more than 120 miles on a full charge and my REX range should be showing 60-70 miles like it used to. For what it's worth, th...

Re: bmw i3 important question

I do about 16,000 miles a year in a i3 BEV (120Ah) which is roughly equivalent to you. It’s more the mix of the journey types you do and where - that is the key. What type of road, likely average speed, how hilly, and are there chargers available on the way? Zap-Map and ABRP apps can help you plan ...

Re: Estimated full range is always LOW

My avg. driving result per the app is 3.8 mi per kWh (many times higher). The usable capacity of a 120 Ah battery pack is 37.9 kWh: 3.8 mi/kWh * 37.9 kWh = 144 mi. That would probably be at a temperature of 25 ºC (77 ºF). One of the reasons for your lower than expected range might be your rather lo...

Re: Estimated full range is always LOW

Since you have a REx, run it down until the REx kicks in, then put it on to charge with a departure time and preconditioning set, so it does a cell balance, and see if the range improves. If it doesn't, you may have a bad cell. Thank you. If there was a bad cell....would there not be a warning for ...

Re: bmw i3 important question

Very much doubt 2 "bad" i3's involved. Not had my 120AH long (non-S) and seen the range prediction vary. Best I've seen so far predicted is 203 miles after playing around with Eco Pro mode and turning off the ventilation during a local trip and charging when arrived home. Today I started off on a l...
