Mitsubishi, GS Yuasa and Bosch Form JV to Double Capacity of EV Lithium-Ion Batteries

FEB 14 2014 BY MARK KANE 18



Bosch, GS Yuasa, and Mitsubishi Corporation just formed Lithium Energy and Power GmbH & Co. KG joint venture, which starts operations in 2014 with the aim for a “giant leap forward in the development of battery technology”.

“The joint venture Lithium Energy and Power GmbH & Co. KG was set up in November 2013. Bosch holds a 50 percent stake with GS Yuasa International Ltd. and Mitsubishi Corporation each holding 25 percent.”

Doubling the energy density is the task to do before – in Bosch’s opinion – EVs go mainstream somewhere in 2020.

Dr. Volkmar Denner, who, as chairman of the board of management of Robert Bosch GmbH, is responsible for research and development, stated:

“In setting up this joint venture, we want to achieve nothing less than a giant leap forward in the development of battery technology. Our aim is to make lithium-ion batteries twice as efficient.”

A Giant leap forward means much greater range (or alternatively the same range with a much smaller and lighter battery pack).

Sadly we don’t know any details on how Mitsubishi, GS Yuasa and Bosch will make this giant leap possible. Initially, development will be conducted by a team of some 70 associates in Germany and Japan

Each company will have some tasks to do in its competence:

Bosch will support these joint activities with its entire portfolio of components for electromobility. With its competence in the area of battery packs and battery management systems, Bosch specializes in the monitoring and control of cells and complete systems, as well as in integrating them into vehicles. In addition, it will contribute its know-how in production processes and quality management relating to the large-scale series production of complex products.

GS Yuasa will contribute its many years of experience in manufacturing lithium-ion battery cells whose high density makes for a longer range, as well as its expertise in materials systems and electrochemistry. As an established manufacturer of automotive and non-automotive lithium-ion battery cells, GS Yuasa has a strong engineering team and modern production lines with a high level of automation.

Mitsubishi Corporation will contribute its global sales network and experience as an integrated global business enterprise. In addition, Mitsubishi will use its strengths in the establishment of global value-added chains – which include raw materials, semi-finished products, and marketing – to take the joint venture forward.

Mitsubishi currently use batteries of around the same specific energy as those in the Leaf, ie at the pack level of the order of 80Wh/kg.

Tesla and Panasonic are already at about 150Wh/kg at the pack level, and whenever the Nissan Leaf gets its 150 mile range they will be joining them at around the same level.

So as far as can be seen this is a bold plan to get up to the same level by 2020!

Let’s hope that is not what they mean.

One possible more favourable gloss is that they are working on increasing specific energy for PHEV batteries, which are a very different thing to BEV batteries as they cycle so much more frequently.
If OTOH they are talking about going beyond the Panasonic/Nissan level, well, they need to catch up first.

So we went from not enough batteries, to a battery over-capacity, and now we need to build more factories? I guess it is hard to get the timing right. And they are still haven’t found a chemistry mix that everyone likes.

I like the look of that futuristic EV on the top photo… I’d buy a car that looks like that!

It does look nice. No huge bulging headlamps or baggy sheetmetal. 😉

2nd Gen i-MiEV concept drawing with a CA-MiEV body? Glass panel doors won’t survive production anymore than they did on the Volt.

Perhaps it’s black over white door panels, mimicking the BMW i3 side windows?

The charge port is in a horrible spot.

(well for the US anyway)

It could be moved. Being forced to back into charge ports, sucks.

I really dig the wheel hub design and did anyone notice it uses side view cameras instead of mirrors? Very well thought out for a generic EV image. Where did you guys get it?

must be BOSCH based.. see numberplate and also these two links:

1) same pic, bigger size:

2) inner guts of the design study:

but yeah you’re right.. hopefully Mitsubishi is taking a close look at that design and doest transform the MiEV into that.
Man, how many sales would they get if that thing would look like that BOSCH design, huh?

Great find! Nissan should also look at it for a Leaf refresh– futuristic car designs should be sleek, not baggy.

some more pics of that design:

3) on the road, different perspective

4) CG model

5) high res of the known pic,7

Not even the CA MiEV comes close to that.. to bad BOSCH doesn’t build cars.

Perfect spot, IMO.

1) Always back in whenever possible – you have maximum visibility when arriving vs backing out with blind spots. When its time to leave, just get in and drive away, again with maximum visibility in the forward direction.

2) Right side port makes more sense for parallel parking at a charge stall in a RHD country. If its a left hand port, and you’re parallel parked on the right side, your cord has to wrap all around to the live lane side.

Seems like a good option (not too expensive) would be offer dual charging ports (front and back).

Then you could also us a range extender trailer/generator on the rear one.


“twice” is code for “don’t switch from our ICE tech, to EV, until we get out of the kitchen”.

I loved Bosch’s evolution from mechanical injection to Motronic, but that was 30 years ago.

Remember the muscle car “war” of the late 1960’s? We are right on the edge of a huge all out battle for the best EV. Is the Tesla a fine car? It could ALWAYS stand to be cheaper, have more range, have more performance, and be lighter weight. All those things are points of improvement and any OEM can jump into this game and offer an amazing vehicle. Maybe the Leaf and MiEV are in a price battle. Just wait till they start one upping each other on the other details. Also; why wait a full year to offer product improvements? I like mid year model changes. Keeps things fresh and exciting. What if the Leaf or MiEV offered 3 different pack sizes at 3 different prices? What if they offered a performance version that could smoke a Corvette? Just wait till SUV’s, full size trucks, and sports cars are offered in electric. RAV4? At a price penalty. Until EV’s are price competitive; they are seen as a disadvantage. Great examples are $8,000 to put a diesel motor into a 1 ton truck and paying $8,000 to have a CNG Honda Civic or full size truck. Pay more to drive… Read more »
