The UK’s best selling electric vehicle, Reva G-Wiz, will shortly be available with a Li-ion battery pack according to the vehicle’s retailer GoinGreen. The city car with a top speed of 51 mph will also have an off-board fast-charger. The new setup will be available in May of this year offer a number of advantages according to the company including:

  • Range increase from 48 to 75 miles
  • Fast-charging off-board – 90% in 1 hr and complete in 1.5 hrs
  • Regular charging reduced to 6 hrs
  • 20% less energy required for charging
  • Lighter weight (15% less) and better acceleration

The vehicle will be priced at £15,795 ($23,300)

Comment: Since this city car is only one step above an LSV and has a price point not that far above higher end LSVs can Li-ion battery packs be that far behind for LSVs? We reported earlier that Dynasty was looking into this possibility. This may become even more likely as states pass more MSV laws and allow for greater functionality in these vehicles. -Mcesare.

Evergreen Electromotive based in Bainbridge Island is raising funds to finish additional prototypes and establish production facilities for three-wheeled utility vehicles. Led by Bob Fraik, a former software engineer from Sun Microsystems and NeXT, the company has already produced the ECH, a four wheeled MSV prototype with a carbon composite body and lithium iron phosphate battery pack giving it a range of 80 miles.

The company is finishing work on two prototype three-wheel vehicles and is looking to establish production facilities in the Port of Bremerton, WA industrial center. The production vehicles are expected to have a top speed of over 50 mph but can be calibrated for lower speeds, and will be targeted for government and corporate fleets. Learn more: Kitsapsun.com

Axeon recently announced that they had nearly doubled the performance of their Lithium ion battery back in on road tests for Modec’s 3.5 ton electric urban delivery vehicles. While independent testing indicated only a 25% increase, prototype tests nearly doubled vehicle range from 76 to 150 miles. Axeon attributed the improvement to a new cell design that increased power density. Based on these results Modec is planning to offer the battery back in the second half of this year.

Electrovaya's Lithium-Ion Powered Maya 300

If all goes according to plan the Maya 300 will be available this summer in the US and Canada.  The LSV will be available with either a 12 KW or 18 KW Lithium ion battery pack, which will give the vehicle a range of 80 km or 120km respectively.  Produced by Electrovaya, the LSV will be priced around $20,000 and will be assembled in either Mississauga, Ontario, or Malta, NY,  the final decision is yet to be made.

The Maya 300 is based on the Chana Benni car which is manufactured by Chana International Corporation in Chongqing (province of Sichuan) with styling by Bertrone of Italy.  Learn more

A recently granted patent provides some more information about the company’s much anticipated technology.  According to one analysis of the patent

An EESU (Electrical Energy Storage Unit) weighs 281 pounds, has a volume of 2.63 cubic feet, can be fully charged in 3-6 minutes, is completely unaffected by temperature, will not explode or catch fire in an accident, and provides 52 kWh of electricity.

Firms Collaborate To Boost US Advanced Battery Manufacturing

Last month an effort was announced by fourteen U.S. technology companies to develop advanced battery manufacturing capabilities in the U.S. The batteries will be lithium ion and targeted for hybrid and electric vehicles.

Seeing the strategic importance of securing a battery supply and developing technological expertise, the companies are trying to secure $1 billion in federal aid to build a manufacturing plant. Firms involved in the effort include Johnson Controls, Enersys, 3M co., Mobius Power, FMC and ActaCell. While some of the technical know-how behind advanced batteries has been developed in the U.S., the manufacturing has migrated overseas to countries like China where, according to the article, over four dozen advanced battery factories are being built.

In a related story, GM has also identified battery manufacturing as a core competency and is planning to build their own lithium ion battery plant to supply their Volt vehicle production.

While the advanced battery production is clearly aimed at highway speed vehicles, the developments should help efforts to improve the performance of battery powered LSVs. While most of these vehicles use lead-acid type batteries, some are using or exploring the use of more advanced batteries. More production, competition and technological advances will only make these batteries more feasible for use in LSVs and utility vehicles in the future.
