Wheego Electric Cars says it has selected traction battery specialist Discover Energy Corp. as supplier of the traction batteries to be used in its low-speed Wheego Whip neighborhood electric vehicle.

Discover produces a power-dense type of lead-acid battery called a dry cell or absorbent glass mat (AGM) battery in which the electrolyte is absorbed into a mat of fine composite fibers.

An AGM battery has no liquid to spill the event of an accident and because of its design and components handles the higher operating temperatures of an EV system better than other lead-acid batteries and holds its charge longer.

It can be charged and discharged more rapidly, and delivers the sustained levels of power needed in an electric vehicle system in a smaller and lighter package than a wet or flooded lead acid battery.DiscoverBatteries.jpg

While lithium ion batteries, which are much lighter and much smaller, are now the preferred battery of manufacturers of most  all-electric  cars, dry lead-acid batteries such as those developed by Discover work well in smaller, lighter low-speed neighborhood EVs and. because they are much less expensive than lithium-ion or nickel-metal hydride batteries, help NEV manufacturers keep costs down.

Wheego said the Discover EV Traction Dry Cell battery packs developed for the Whip - a Chinese-built car with a strong visual resemblance to Daimler's Smart Fortwo -  will provide up to 40 mies of travel, at speeds of 25 mph and lower, on a single charge.
