Will 'LG Chem inside' be the calling card of this early EV era?
The big news on the electric vehicle front today is that Nissan is considering slowing down EV battery production in the US and UK and source all of Nissan's big packs come from Japan. Nissan may also buy some batteries from the Korean company LG Chem. This is apparently causing dissent within Nissan, but it follows what Alliance partner Renault is doing in the hunt for 180-mile EVs.
Just how intimate would you like to get with the powertrain in a Chevy Volt? If you're anything like YouTube user d55guy, then spending a half hour filming yourself taking apart the battery pack, motor, inverter and more for a look inside sounds like your idea of fun. After all, this way you get to see the cooling system, the heavy safety kill switch and count up the individual cells in the battery modules. Fun!
The first of perhaps 'hundreds' of gigafactories is now one step closer to reality: Tesla and Panasonic have announced their official agreement to work together on the gigafactory. The two companies have worked together for many years on electric vehicles, but this new deal takes the partnership to a whole new level.
Panasonic's standing in the plug-in and hybrid battery production industry has zoomed ahead like a Tesla Model S taking off from a standstill. That's appropriate because the Japanese company's relationship with the California-based automaker has been the primary reason for its growth, which looks like it will continue to be rapid.
There's a near endless list of things in automotive drivetrain technology that have changed since 1930. Oddly, the way scientists think about at how lithium-ion movement affects the performance of batteries is not one of them. Of course, not a lot of people were thinking about battery-electric drivetrains 80 years ago (the original battery-electric car era was long gone and gas-powered vehicles were the standard), but there is a lesson here.
When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and w
We made our gigafactory predictions the other day and, it turns out, we were pretty much on target. Today, Tesla Motors released the first official details on its upcoming massive battery plant and we see sun and wind power feeding energy into a plant that will employ around 6,500 people and make enough packs for around a half-million Tesla EVs a year. You read that right. Tesla is getting ready to produce 500,000 EVs a year, and that's already in 2020. Tesla hopes to start selling a lower-cost
There's a growing hubbub in the plug-in vehicle community over what looks like some ridiculously cheap replacement batteries for the Chevrolet Volt going up for sale. GM Parts Online, for example, is selling a replacement Volt battery with an MSRP of $2,994.64 but, with an online discount, the price comes down to $2,305.88. For the 16-kWh pack in the 2012 Volt, that comes to a very low $144.11 per kilowatt hour (kWH). But is it a real deal? How can it be, when a Chevy dealer may quote you a pric
Oh man, there's another one of these studies on electric vehicle batteries that sounds too good to be true. Lawrence Berkeley National Laboratory researchers are working on a breakthrough in lithium sulfur EV battery technology that could increase energy density to four times that of current lithium cells. The demonstrable discharge/charge cycle is estimated to last through 1,500 cycles, which means that a car using this tech could theoretically go something like 450,000 miles without requiring
Tesla Motors is on the move today, announcing an expanded deal with Panasonic for more and better lithium-ion automotive batteries as well as progress on the US Supercharger network. To go along with the Supercharger news – which is all about the West Coast – Tesla is taking a specially marked #DriveFree Model S (complete with social media campaign angle) along the route offering, yes, free drives. The opening of the West Coast Supercharger Corridor along US Highway 101 and Interstat
Mention the term "alkaline battery" and folks of a certain generation will remember the old Eveready battery commercials with actor Robert Conrad daring the viewer to knock the battery off his shoulder. Very macho. Now, alkaline has moved from manliness to money-saving, as the fine folks at Princeton University have been granted almost $1 million from the US Department of Energy to develop alkaline batteries suitable for electric-vehicle use, Princeton Patch reports.
