A123 Systems' new lithium ion tech keeps EV batteries cool, your wallet in check

EV battery maker A123 Systems has had a rocky history as of late following a Fisker battery recall, but it may just be turning the corner with a new lithium ion advancement. Nanophosphate EXT widens the temperature range that A123's lithium iron phosphate-based batteries can withstand before losing power: an EXT battery musters 20 percent more power than before when it's as chilly as -22F and can keep over 90 percent of its original capacity after 2,000 full charges, even if it's been run in a blistering 113F heat. The longevity has its obvious advantages for anyone who lives in an extreme climate, but it could also lead to cheaper EVs and hybrids -- the less cooling a car battery needs, the lower the up-front cost and the lighter the car gets. Full production won't start until the first half of 2013, though that's ample time for companies to at least think about slotting Nanophosphate EXT battery packs into 2014 or later cars such as the Atlantic.

Fisker leak shows Atlantic production delayed to mid-2014, 0-60 in 6.5 seconds

Our hopes of taking the Fisker Atlantic for a spin next year just got dampened considerably: a big document leak has revealed that the more reasonably-priced alternative to the Karma won't be rolling off the production lines en masse until mid-2014, a year later than we'd expected. Thanks in part to a factory overhaul, the only Atlantics rolling on their hybrid-powered wheels in mid-2013 will be prototypes. On the upside, we've learned more about the car itself, including a fairly brisk 0-60 time of 6.5 seconds courtesy of a 300HP-equivalent motor. Green drivers who thought that the promised lower price would put it into entry-level luxury will nonetheless get a reality check with that $50,000 to $60,000 target, even if it's still a big savings over the six-digit Karma. There's still a huge amount of leeway for things to change, but with our compatriots at Autoblog having confirmed that the documents were real and "highly confidential," they may be a sign that the Tesla Model S will have free rein in the green luxury sedan world for a good year or more.

Midtronics GRX-5100 simplifies servicing hybrid and EV batteries

Midtronics GRX-5100 simplifies servicing hybrid and EV batteries

As we move away from traditional fossil fuel-burning automobiles towards hybrids and EVs, we're presented with new challenges -- namely servicing those vehicles and their high-voltage batteries. When it comes time for transport, in the event of an accident or when components need to be serviced individually, it's necessary to completely drain the cells on board, and that's where Midtronics' GRX-5100 comes in. The vehicle battery service and de-power tool is wrapping up field testing at GM and may soon find itself in "reclamation yards" (read: junk yards) as well as your local mechanic. With testing out of the way Midtronics plans to ramp up production before the end of the year, and its updateable firmware means it will be able to handle future vehicles with nothing more than an upgrade loaded on a USB key. For more info check out the PR after the break.

Fisker rep defends Karma hybrid sedan in garage fire aftermath

Fisker rep defends its hybrid sedan in garage fire aftermath

Last week, a newly purchased Fisker Karma went up in flames, damaging its owner's home and earning the company behind that hybrid sedan plenty of bad press. The auto maker hasn't submitted an official explanation for the fire, though the former chief engineer for the late General Motors EV1 electric car places the blame on the hybrid's tight engine bay packing. Fisker clearly isn't having any of that -- according to the company's director of powertrain:

Our technologies and engine design have been fully tested and certified at the highest level. It is irresponsible and ill-informed for technology pundits to suggest otherwise in order to secure media attention for unfounded claims.

No defensiveness there, then.
