The Honda EV Plus was the first battery electric vehicle from a major automaker with non-lead acid batteries. Roughly 340 EV Plus models were produced and released. The EV Plus was taken out of production in 1999 when Honda announced the release of its first hybrid electric vehicle, the Honda Insight. The EV Plus was made to learn about advanced battery use in an electric car and to meet California Air Resources Board requirements for zero-emission vehicles, the same as the new General Motors EV1. It served as a test bed for the pancake-style motor, electronic control unit, power control unit and the Nickel–metal hydride battery (NiMH) later used in Honda hybrids and developed further in the first Honda FCX Fuel Cell Vehicles made from returned (decommissioned) EV Plus chassis.
