Non-lead acid batteries were never used on electric vehicles before Honda EV came along.
About 340 Honda's of this model were manufactured. In 1999, however, Honda stopped producing EV model because that is when Honda released the Honda Insight, its first electric hybrid car.
The EV model complied with zero-emission vehicle requirements set forth by California Air Resources Board. This model served as a testing ground for many of Honda's innovations. These innovations included the new power control unit and the pancake-style motor, not to mention the nickel-based battery and electronic control panel. These innovations were later used in other Honda vehicles, especially the Honda hybrids. Some of these innovations were improved in Honda's first fuel cell cars assembled from decommissioned vehicles of the same model.
The EV model had lots of cool features that were considered top-of-the-line for its time. Some of them included regenerative braking, HID headlights, the Avcon connector, regenerative deceleration, and passive battery balancing, not to mention electrically heated windshield and climate control. Moreover, this model of Honda was different from all other vehicles in its niche because some variations of it had oil-fired heaters. Only the units sold in climates with low temperatures had oil-fired heaters.
Though for its time this was an excellent vehicle, driving style could decrease the range of this vehicle, especially if the driver chose to ride it with high speeds and accelerated rapidly. This driving style could have created problem for this vehicle because the all-electric range of this Honda could be lowered by fast speeds.
The interesting fact about EV is that Honda never allowed it to be sold. Instead of selling, Honda allowed people to lease it for only $455.00 a month. When the lease ended, some owners were allowed to extend it. However, most EV Honda's have been scrapped.
