Some new i3 photos are out. I did a quick blog post and put them together there if anyone is interested: http://bmwi3.blogspot.com/2013/04/bmw-slowly-undressing-i3.html" onclick="window.open(this.href);return false;

This article breaking down a BMW video is amusing. Humor aside, IMO this ad sends a negative message by portraying EV drivers as slaves to the technology, restricted to hopping from one charging point to the next and constantly having to monitor the thing... with freedom only coming when they get their gas car loaner.

And why is that guy testing the 120 outlet anyway?

The video is actually for BMW i's mobility service called 360 Electric, not for the i3. It's supposed to show some of the services they will offer like home EVSE installation, ParkNow, DriveNow, ChargeNow, gas loaners for i3 customers...etc.

I suppose the 120v outlet testing is just supposed to show an electrician doing something, lol. If you look closely at the video, you can also see the car (this is the only i3 concept coupe in existence) has a Mennekes charge port because that's the European standard, but the girl is attempting to plug a J1772 connector into it. Oops!
 
Not sure if this is the right thread for this, but since it's about my ActiveE and on BMWBLOG I figured to post it here.

I did a post for BMWBLOG on the battery capacity loss I've measured on my ActiveE after 44,000 miles and 1,000 recharges. I know battery capacity loss is an important topic here so I thought you'd appreciate the link:

Very cool. How often do you run the battery down below about 5%?

I can check my logs but I'd guess about 25 times now. I've actually ran it till it stopped three times ;)

Very impressive reasonably small losses you noted in your article. Nice job on the logging/blogging.

...When the car was new, I was measuring on average about 27.4 kWh’s available to me and now that number has shrunk to about 25.25 kWh which is about an 8% capacity loss....

How do you measure your available kWh?

Doesn't sound like ATM gives much if any benefit in your climate.

But since you'd need a LEAF with ~ the same charge cycles and temp exposure and with an accurate range test or metered recharge record to determine the LEAFs actual available capacity loss, and to compare with yours, we probably can't answer that question.

That's an NMC chemistry, correct? This is the chemistry slated to be in the LEAF in the future.
Click to expand...

Yes, exactly. They were developed by SB-LiMotive which was a partnership between Samsung and Bosch. The ActiveE was the first EV to use these cells. Now the Fiat 500e will be using them and once BMW i launches all of their plug in offerings(for now the i3 & i8 but others are in development) will use them. BMW is very happy with their performance so far.

Recently Bosch bought out Samsung though, and the new entity is called Robert Bosch Battery Systems.

I record info like my consumption rate, starting & ending SOC, and miles driven every time I plug in. by having that info I can calculate what capacity is available to me, especially with driving the car to zero state of charge on occasions. The graph represents 1,000 data entries(recharges) with one point on the graph for the average of the last 40 records. I also monitor the energy used to recharge the pack. With that I have to factor in charging losses though but the decline does mirror what I see from my driving records.

Of course it will qualify for the full $7,500 federal tax credit. The author just isn't knowledgeable on this matter. Any plug in passenger car (BEV or PHEV) with a battery 16kWh's or larger qualifies for the full $7,500 tax credit. John Voelcker did a follow up story on this: http://www.greencarreports.com/news/1083960_2014-bmw-i3-electric-car-price-to-be-similar-to-bmw-3-series" onclick="window.open(this.href);return false;

The article has been discussed in other circles and it's poorly researched. There is no reason why the i3 wouldn't qualify for the $7,500 Federal tax credit because that credit is based on battery capacity, not on the gas range extender. Same reason the Volt qualifies for the full credit.

The Calif rebates are another matter. The rebate for the REx version is yet to be determined. Perhaps that was the source of some of the confusion.
 
The dust hasn't settled on Frankenplug, but here goes the next "standard" battle. How come I think it will be everybody involved EXCEPT the leader in volume EV production, Nissan?

"Inductive charging potential is now an ongoing subject for BMW; the company wants to see an international standard established and has founded an official workgroup with German manufacturers under the aegis of the German Commission for Electrical, Electronic & Information Technologies. BMW says various manufacturers are also communicating on the issue at an international level."
 
Interesting article on how the BMW i3 is made, including a lot of information about the CFRP construction and plastic exterior panels, and a little detail on how the battery cooling system works:

http://www.sae.org/mags/AEI/tools/12056" onclick="window.open(this.href);return false;

The i3’s Drive Module is provided by BMW’s Dingolfing plant and completed at Leipzig. It is screwed and glued to the Life Module. The underfloor lithium-ion battery has eight modules and 96 cells. Although the cells are supplied, the battery modules are a proprietary development of BMW and manufactured at Dingolfing. The individual battery blocks each have their own safety system.

The car’s air conditioning refrigerant cools the i3’s battery pack, obviating the need for fans or additional pumps. Heat for preconditioning in low temperatures comes from the charging electricity supply. The cabin is heated via a heat pump in urban traffic, a 30% saving against regular electric heating. Battery performance typically shows a 5% degradation at -15°C (+5°F), and testing has been completed down to -35°C (-31°F).

In addition, the odd way that the IL EPA cash rebate on EV's would also qualify (if they still have funds) on the i3 with the range extender version because it will be quite similar (although less overall range) than the Volt being a 'generator' type engine to the battery pack and not just an ICE with a battery pack (like the C-Max Energi which doesn't qualify). AW speculated like others than it would retail around $45K but not sure how much more the range extender model would cost but with a total range of 186 miles it's not bad.
