Here is a demonstration of the battery switching technology. With the Better Place approach, drivers do not own the batteries. The batteries are supplied as a service.
The battery switch is only necessary for long trips. For single charge range, the batteries are recharged at charging stations in the owners garage over night.
Based on this technology, Israel claims they are going to end oil dependence by 2020.
