BMW takes nod from Tesla, opens up its own battery patents

Looks like things are starting to get interesting...

BMW has battery patents?
Who knew!!

Not to be cynic, but BMW may be doing this as a PR stunt. I mean, they made an EV that can only be used to tool around town. what is so revolutionary about that?

as an example of something not to make?

Some years ago BMW did a big hydrogen innovation campaign that consisted of letting some celebrities drive hydrogen fueled 7 series cars. Near as I can tell it was all just embroidery on an ad campaign (and I had a BMW at the time)

One difference is that BMW uses automotive grade batteries manufactured by Samsung. I do not know the difference between "automotive grade" and what Tesla uses, which is an assemblage of over 7,000 customized laptop cells. I believe BMW's technology is liquid cooled and sits along the bottom of the car, similar to Model S. It's just a much smaller capacity.

Tesla also uses Automotive grade batteries. They are designed to work in a much higher temperature range, handle significant shock and vibration, and usually have different charge and discharge profiles that are appropriate to use in an automobile.

Not to be cynic, but BMW may be doing this as a PR stunt.

Heck, Tesla did it as a PR stunt! Worked pretty well, too.

"To gain economies of scale, BMW is open to sharing with rival automakers the electric-vehicle battery cell technology it co-developed with Samsung SDI."

That is the result of their visit in Fremont... to overcome the price barrier there has to be economy of scale - no way around it.

Also interesting is that BMW makes 100 i3 a day...

"The automaker said it raised i3 production to 100 units a day starting in April and will raise output by further 40 percent at the end of summer. "

How does BMW bridge the massive gap between the ugly i3 with paltry range and the $135k i8?

They could make a $135,000 BMW i8 with a 66 kWh battery pack, that was Supercharger enabled, without an ICE in the back...

@ jai9001
I would assume with an i5 and an i7. But the question will be whether they will they be able to price them competitively. I think this is the reason automakers have shied away from the 70k to 120k range, they know their product wouldn't be able to compete with the MS. (The ELR is the notable exception and we see how that worked out for GM)

Bobby has 10 peanuts. Billy has 100 cherries. Billy: "Bobby, I'll give you half of mine if you give me half of yours!"

Oops. Flipped my circuits. Try again:

Bobby has 10 peanuts. Billy has 100 cherries. Bobby: "Billy, I'll give you half of mine if you give me half of yours!

Cue, not nod.

You are slipping, Brian.

i3 sold at a rate of about 11K a year in the first half, with each car about ¼ the capacity of an MS-P. With a (relatively) heavy ad campaign to try and drive it. Samsung may experience the excess production capacity melt-down of its dedicated line another maker of supe-dupe batteries; "123 and yer out, at the old ball game!"

typo: ... of another maker ...

"i3 sold at a rate of about 11K a year in the first half... With a (relatively) heavy ad campaign"

That's actually very true. Looking at their ad alone one may think it is a very successful car.

And then repairing damaged cars can be quite difficult. If few can work with aluminium how many can actually work with fiber glass?

A lot of body shops can work with fiberglass. Corvettes, after all, have been around for a long, long time.

And soon a lot of shops will be very experienced with aluminum. The highest selling truck in the US is now using aluminum.

What? BMW has a battery patent on it's i8's 20-mile battery range? :-)
