Scientists at EDrive Systems, based in Los Angeles, are developing
a new battery system that replaces a Priuses
installed battery with a lithium ion battery that can be charged at home using a standard domestic power socket. The converted system should be able to get Priuses to over 120 mpg (if I've done my math right. The original article is from South Africa, I think, and says the new system can get about 100 km per less than two liters, which is 62 mile for about half a gallon, right?) for about $12,000.
Greg Hanssen, partner and chief engineer of EDrive Systems, said his company has an interest list of thousands of customers and that customers in Southern California will be served first once the technology is fully tested.
