Re: Battery capacity issue

My home charger (Chargepoint) gives me the amount of KWH's that was transferred to my i3 during a charging session. That's not the energy actually used to charge the battery pack due to some of the energy being converted to waste heat during charging. The Idaho National Labs measured a 2014 i3's ch...

Re: Battery issue

However, for the price of $750 they would perform a 24 hour diagnostic suggested by the regional experts. I wonder why the cost of the test is so high... AFAIK, it's performed simply by connecting ISTA+ software to the car via ODB2 port and running a diagnostic in the app. The car is gradually disc...

Re: Battery capacity issue

We have a huge fleet of used Leafs from the US in Ukraine, a lot of 2011-2013 MY ones as well. Most of these cars have either dead or almost dead packs, quickly approaching or in some cases going below 60% SOH. There's also a burgeoning cell repackaging industry here catering to the needs of these L...

Re: Battery capacity issue

Interesting article by an i3 owner, and the formula he uses to track his battery capacity, since both the GOM range and the battery kappa/max aren't reliable measures. https://www.bmwblog.com/2017/04/24/bmw-i3-long-term-battery-capacity-report-better-expected/ I've been tracking estimated SOH both ...

Re: Battery capacity issue

It is true that there is no instantaneous way to measure a capacity of any battery pack (many different capacities exist depending on conditions). So it would be difficult to provide an i3 driver with a definitive pack capacity. This is a very fair point. It is sad though, that it's true for BMW th...

Re: Battery capacity issue

That's a very convenient position indeed! BMW learned well from Nissan's mistakes - those poor guys would replace a battery as soon as the dashboard bars go below 9. But in case of BMW only dealers can say if the battery is OK or not. And it's usually OK from what I read here and other forums. You s...

Re: Battery Diagnostics

Sure they do, for decades. And Ukrainians buy lots of BMWs locally, a very popular brand here. They choose not to proceed for reasons they don’t explain (I’ve contacted the representative office on this matter). Once ConnectedDrive is supported, it would be a matter of TCB unit replacement for me. B...

Re: Battery Diagnostics

Oh, I got it now, I didn't understand your first message. Yes, seems like all owners in Germany have this in-app SocMax indicator, very convenient. It's great you can now run it as well.

I didn't check how to do it since BMW won't support ConnectedDrive in Ukraine, so the app won't work either.

Re: Buying BMW i3 Bev 60ah

The battery looks to be in good condition for 58K km and three years. E.g., my 60Ah BEV, almost 40K km, shows 17.0 kWh now in winter. I don’t expect this number to hold at this level during the following 18K km.
