History
Lateral view of the AC Propulsion eBox

AC Propulsion executives announced their intention to convert Scion xBs to battery electric vehicles in October, 2003.[1] Company executives stated that the Scion xB was chosen in part due to its boxy shape which allows for good placement and installation of a battery pack. The availability of a suitable battery was said to be an important step in allowing for the announcement of the program. Suitability requirements included that the battery be widely available ("off the shelf"), in volume, without danger that supply would be cut off or be overly limited. Thousands of lithium-ion batteries, of the 18650 variant, were proposed as suitable for the rechargeable battery system.[2]

The prototype eBox was unveiled in Santa Monica, California on August 18, 2006. The prototype used a battery pack consisting of 5,300 Li-ion cells arranged into 100 blocks of 53 cells each.

The first production eBox was delivered to actor Tom Hanks on February 15, 2007.

Pricing

Estimated cost of this conversion exceeds US$50,000 in addition to the base vehicle cost (excluding the cost of the gasoline engine, that is replaced in the conversion), while high-volume OEM additional cost is projected at about $10,000. It appears that high-volume production by original vehicle manufacturers using AC production components is a goal, with the low-volume production being an intermediate step.

AC Propulsion offers the conversion for US$55,000.[3]
