A family of Tesla patents and pending applications relating to a hybrid battery system has been generating a bit of buzz (see, e.g., Cleantechnica’s story here).
The patent family includes U.S. Patent Nos.
General Motors CEO Dan Akerson recently claimed that his company plans “to compete head-to-head” with Tesla Motors on plug-in electric vehicles. Given the current lineup of products offered by both companies, that’s a little hard to envision. Tesla makes high-end, electric-only performance vehicles, while GM has so far released a comparatively low-priced plug-in
Here’s the common refrain from electric vehicle skeptics: electric vehicles aren’t necessarily that much cleaner than conventional vehicles and hybrids—even though they burn no gasoline and have no tailpipe. As the argument goes, electricity produces air pollution upstream, before a “zero emissions” vehicle even hits the road, and manufacturing
A previous post discussed advanced battery maker Electrovaya’s lithium ion polymer technology, which the company says provides faster, more efficient transport of lithium, and therefore greater energy density.
Several years ago, Electrovaya partnered with Tata
Portable solar power light solutions are the way to go, especially for people living in areas without a grid connection. That’s why we love Luci, the solar light.
Created by Micro Power Design, a self-proclaimed “technology incubator, accelerator and manufacturer
While car sales of hybrid models have shown a steady increase in the last decade, there is still a perception that the green benefits of going hybrid come at the cost of limited performance. This is largely due to the absence of hybrids from the racing scene, which is the platform where popular cars like the Audi A8 and the Subaru Impreza initially gained their prestige.
Leyden Energy (Leyden) is a Silicon Valley company that has developed a lithium ion battery that uses imide salts as electrolytes instead of the more commonly used PF6-based electrolytes. Formerly known as Mobius Power, Leyden built it Li-imide battery platform on seed technology from a patent acquired by DuPont.
It’s not every day that you see an electric vehicle driving down the street. Certainly for me, I don’t see electric vehicles parked in the garage of my building. So, when given the opportunity to test drive the Mitsubishi i-MiEV, I jumped at it. I always wondered what it would be like to drive an electric vehicle on the streets and freeways of San Diego.
The promising but financially troubled A123 Systems lithium-ion battery maker announced yesterday that it has made a significant advance in battery technology that will enable electric car batteries to last longer and cost less.
A123 has been a leader in the race to develop
Valence Technology is an Austin, Texas, company that develops and manufactures long-life lithium iron magnesium phosphate batteries.
Valence recently won a victory in the European Patent Office (EPO) Opposition Board when the Board dismissed an appeal of a decision revoking a European patent held by rival Hydro-Quebec (HQ).
Mitsubishi Motors has developed a reputation for developing sport inspired vehicles that outperform more expensive sports cars yet are reasonably affordable (See the Lancer Evolution). When it comes to electric vehicles, Mitsubishi has not been generally considered part of that world. However, this has recently changed as Mitsubishi ls now taking
A U.S.-based company says it has developed a new lithium-ion battery with an energy density of 400 watt-hours per kilogram — roughly twice the density of existing rechargeable batteries — an innovation the company claims could significantly increase the range of electric cars and ultimately cut the price of battery
Announced on February 14, the Obama administration’s Department of Energy (DOE) budget recommendation is a big valentine to those working on developing batteries for electric vehicles.
As we said last year, the current administration has focused the majority of its vehicle technologies
