2014 Energy Storage Symposium - JB Straubel's Keynote

Tesla Motors CTO JB Straubel talks about Energy Storage and it is pretty interesting ...


Keynote presentation given by JB Straubel, Chief Technology Officer, Tesla Motors at the 2014 Silicon Valley/ SEEDZ Energy Storage Symposium. The symposium was hosted by Joint Venture Silicon Valley on May 21 at Microsoft in Mountain View, CA.

The symposium engages key stakeholders in the energy storage marketplace around the latest developments, challenges and opportunities for customer-side storage, and how Silicon Valley is advancing innovation and uptake in this critical emerging market. Held annually since 2010, the symposium features presentations from national and state-level experts, high-profile solution providers, on-site energy storage customers and utility interests.

Fremont plant also has Energy Storage Systems, 5 actually providing 1MW, storing 2MWh !

Nissan LEAF with 300 km Range on sale by 2017

Nissan's next-generation Leaf electric vehicle will have a new battery that more than doubles its range. And Infiniti's delayed electric car will debut with the improved battery by early 2017.
Nissan executives shed more light on the automaker's next EVs, saying better range is key to higher sales. Nissan launched the Leaf in December 2010 and has already improved its performance. But engineers are working on a big jump with a revamped battery by 2017.
A new battery chemistry will debut by then for use by Infiniti and Nissan, said Andy Palmer, executive vice president in charge of Nissan's zero emissions and Infiniti businesses.
"The battery chemistry is all about range and energy density. That's where you see the technology moving very, very fast," he said in an interview last month at the Beijing auto show. "This really is the game-changing technology."



Longer range
Palmer declined to offer a target range. But the battery must deliver up to 300 kilometers, or 186 miles, for EVs to present an everyday alternative to the hydrogen fuel cell cars that rivals are developing, he said.
During an interview at the LA Auto Show, Pierre Loing, vice president of product and advanced planning and strategy at Nissan, hinted that his company may offer multi-pack size option that might increase range to 400 km.
Nissan have been working in a lithium nickel manganese cobalt battery chemistry since 2009 that was expected to enter production by 2015.
Nissan has not announced timing for the next-generation Leaf. But Palmer said the car is on a normal product cadence, from a full global launch dating to 2013: "I think if you thought about a normal model cycle from 2013, that would be more realistic."
That would put the next Leaf's arrival just after Nissan's Power 88 business plan, which ends March 31, 2017, he added.
The Infiniti EV, however, will go on sale "close enough to be counted" as part of Power 88 and should arrive before the luxury brand gets its long-awaited top-shelf halo car, Palmer said.
"I think the EV will come earlier," Palmer said, citing tightening government emissions rules, particularly in China. "To some extent, EV is now becoming practically a requirement."


Better batteries
The Infiniti EV will get the company's next-generation battery chemistry and feature wireless inductive charging, he said.
Infiniti had delayed the EV to wait for better battery technology. The debut was initially slated for 2014.
The Infiniti EV may have a greater range than the Leaf because its sedan packaging can accommodate a bigger battery.

EVTV Friday Show - March 21, 2014

- New CALB LiFePo4 battery lineup announced

- Bottom balancing of the Better Place battery pack

- We show the Hauber Siemens Twins dual AC motor

The very long process of Bottom Balancing, especially with this big 48 modules pack ...
But it is worth it and has to be performed only once
I did the same with 3 modules and it took me roughly a week ...



New CALB LiFePo4 battery lineup announced: A much smaller format and a great improvement in Energy Density !
