BMW i3 with 55 kWh battery at Electronica Show

BMW i3 with a 55 kWh battery

Linear Technology and its design partner LION Smart, are demonstrating an improved BMW i3 at the Electronica Show this week in Munich, Germany.

While both companies are more proud of “demonstrating the industry’s first wireless automotive battery management system (BMS)” for us, the best features of the improved BMW i3 are the battery and the charging system.



By using Kreisel Electric liquid cooled battery cell modules, they were able to put a 55 kWh battery in the BMW i3 that can be charged in just 15 minutes (probably from 0 to 80 %). This electric car has an estimated range of 400 km in real world driving.


Kreisel Electric battery cell modules show us again what is possible to do today with current battery technology. First we saw the improved Volkswagen e-Golf, now it’s BMW i3 time.

A BMW i3 with a realistic 400 km range that can be charged in 15 minutes is immune to range-anxiety.

Now that the Tesla Model 3 is not very far away, German automakers need to wake up and start building good electric cars or they’ll become obsolete.

With production scheduled to start in mid-2017 the Tesla Model 3 is about to make BMW, Mercedes and Audi cars look overpriced for what they offer. The only way to offer top performance while keeping costs low and comply with emission standards is to go electric.


What do you think? Will German automakers start acting before it’s to late for them?

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

German automakers have no interest at all in produce EV, because that means the lost of the high profits that traditional ICE give with maintenance. This will be their own death.

A 55 kWh i3 would be awsome and probably drive up its sales…

The Germans will be just fine…
Aside from Tesla and Nissan no one has publicly made bigger EV plans than BMW, Mercedes or VW…
Globaly the EV market is not even .5% yet so who ever wins and loses is yet to be determined…
Toyota has barely anounced 1 future EV for 2020 and it sounds like a compliance car that will only be sold in CA as far as the US is concerned and I doubt they are going to go quietly in the EV car revolution…
A much better question is will FCA, Honda, Ford and (insert legacy auto co here) act before it is to late??

It is a typical view of the world that world leading companies become obsolete overnight because they see the present and extrapolate based on that.

The fact that the electric car market is a tiny fraction of the cars on the road ignores the fact that you are in the base of the huge wave coming to crash.

I bet with you RIM also though they had many years of market leadership to deal with Apple when the iPhone was first announced… How did that go?

Useless comparison, because phones are low value products designed for maximum 2 years usage. RIM and Nokia went down, because they had no customer binding, Samsung, LG, Sony and others survived the iPhone and grew with it.

If a small independent company do this why can’t BMW do this at car build in the their factory? 😉

Because it would cost $100k

OK can someone provide the real cost of this upgrade.

Prototypes don’t need to go through crash safety. No word about weight, nor did they show the battery pack at all. It’s properly partial inside the passenger cabin.

15 minutes charge for 55 KWH! Impressive.
So that’s ~ 200 KW charge power.
Quite some infrastructure alterations needed to achieve that. – Don’t get too excited and expect to manage it from your garage anytime. Not, in fact, ever. :). It would need a mains cable about 60mm in diameter.. Most UK domestic electricity supplies to smallish house with moderate internal usage might be expected to spare about 5% of that rate, perhaps 5 hours then, which we can do today for many EV’s .
EV’s are brilliant, but few people really appreciate the enormous energy density squeezed into a tank of polluting petrol.
