During a keynote address at the 4th Symposium on Energy Storage: Beyond Lithium Ion, Jürgen Leohold, head of Volkswagen research, stated that although the automotive industry is leaning towards electric mobility, little progress has been made in the 111 years since Ferdinand Porsche introduced a battery-powered vehicle at the world expo in Paris.
That vehicle, according to Leohold, was equipped with a 24-kWh lead-acid battery pack, hub-mounted electric motors and boasted a range of approximately 50 kilometers (31.1 miles). This sounds awfully similar to some of today’s plug-in cars, so is anything really different? Of course there is. Leohold said:
So what has changed? What has changed the business mainly is that lithium-ion batteries have come around and finally supported an energy density that allows you to build a halfway decent car.
Leohold says that electricity used to charge plug-in vehicles must come exclusively from renewable energy sources. Otherwise, as Leohold claims, plug-in vehicles have no emissions advantage over today’s fuel-efficient conventional automobiles (the data shows otherwise, though).
In the 1970s, Volkswagen launched two electric vehicles but, Leohold stated, sales figures were pitiful. We expect the Golf blue e-motion will fare better.

Hisense is still betting on the WHDI horse for wireless HD. The standard’s standard-bearer AMIMON announced its chips would be powering a new line of accessories from the Chinese manufacturer at the Global Sources Electronics & Components World Expo (GSECWE?), including a transmitter for laptops (above), a case for iPhones, and a receiver for TVs (both below). Obviously beaming a round Super Mega Worm to your big-screen is enticing, but we’re sure you’re most excited by the ability to stream Hulu from your laptop to your TV while reclining on the couch. And if you’ve got a 3D set, fret not, WHDI can push polarized pixels thanks to support for HDMI 1.4a. Sadly, info on pricing and availability is nonexistent, but we wouldn’t expect to find these in your local Best Buy. Yet.
