Re: Charging to 80% capacity

Side note: One of the newer Level 2 charging stations in my area has a button you can press to stop charging at 80%. This is interesting because my understand of L2/ J1772 is that the state of charge for the car is not communicated to the EVSE like it is over CCS. So it would be impossible for the ...

Re: Charging to 80% capacity

You set departure times (up to three, for different days of the week). Make sure departure times are selected. Then you select "charge in time slot", instead of "charge immediately". I use one departure time for weekdays (9 am), and one for weekends (11 am). These two are always...

Re: Home charger not working: red light is on.

Thanks for posting the reply on how you fixed it!

Though I don't know what EVSE you were using, from how you describe the solution, "silly mode" sounds a lot like the way I've seen other devices describe a ground fault interruption mode that requires a reboot of the device to reset.

Re: 2015 BEV - Weird Malfunction - Brake & Charging Warnings

I am thinking of taking the car to get scanned to see what codes pop up before heading over to the dealership. The thought of the dealership and the per hour costs drives me nuts! The Bimmerlink app and a corresponding OBDII adapter can do the code scan as well. That could be a reasonable investmen...

Re: Warranty Transferrable for 2014/2015?

As a used i3 buyer myself, one of my assumptions was that the battery warranty did transfer. I've read multiple references indicating that in the US it is federally mandated that EVs have an 8year, 100k mile warranty on defects (which is why US i3s use 100k miles instead of 100km), however it is sh...

Re: Warranty Transferrable for 2014/2015?

Apologies if this was already asked/answered but my search did not find it. Wanted to know whether the battery 8yr/100k mi warranty is transferrable to owners buying used? If it matters, I live in MD and would purchase in MD/VA/DC. I just test drove a 2015 base and the fully charged I3 was at 45 mi...

Re: Charging to 80% capacity

It has been on all i3s from the beginning. I guess your are charging on a low amp charger. If you have a high power charger, the car will calculate when it needs to start charging to get to 100% just before your departure time. The idea is to minimize the time the car spends at 100%. When you plug ...

Re: Charging to 80% capacity

I speculate BMW can't retroactively introduce charge limiting into i3 software because it would open them up to a whole bunch of claims. So they'd rather stay mum on the matter and move on to the next... That seems logical and it does fit with how other manufacturers have altered the available batt...

Re: Charging to 80% capacity

Likewise, even BMW with their new i4 and iX is providing an 80% suggestion, plus charge limiting, and even current limiting. On all the products I sell, I advise people to put them in a hermetically sealed box and never use them. It really cuts down on my warranty costs. I'm pretty convinced BMW is...

Re: Charging to 80% capacity

BMW came up with departure time charging scheme for the i3, the hope is that you won't let the car sit at 100% charge for extended periods. If you charge to 100% using departure time, it is OK. The problems arise when you charge to 100% and the car sits for a few days, or weeks. Departure time char...
