All you Prius owners out there who have been waiting patiently to to start running on grid power can almost stop holding your breath. Hymotion, the company that has been developing a plug-in kit for the Prius, has now started taking deposits for the L5 conversion kit. The kit costs $9,995 plus $400 for shipping and, of course, any applicable taxes. That price includes installation at an approved shop and a three year warranty. The first deliveries and installations should start this July.

The kit consists of a 5kWh battery pack filled with A123 lithium ion cells that fits into any second-generation (2004-2008) Prius. The pack can be fully charged in 4.5 hours at 110V and Hymotion claims a converted Prius will get up to 100mpg for 30-40 miles. Your mileage will of course vary. The pack has been crash tested and meets all current federal safety standards. Hymotion was bought up by A123 last year after doing a number of conversions for fleets and government testing.
