Whats a “plug-in hybrid”?
Plug-in hybrids are the same as a hybrid with the added ability to charge the battery from the electric power grid as well as from the internal combustion engine. However, there are currently no plug-in hybrids on the market. There are hobbyist conversion kits for some models of hybrids. Many manufacturers are working on plug-in hybrids, however, and we will see them on the market in the very near future.
