Editing Hybrid vehicle (section)

===Continuously outboard recharged electric vehicle===
Some [[battery electric vehicle]]s can be recharged while the user drives. Such a vehicle establishes contact with an electrified rail, plate, or overhead wires on the highway via an attached conducting wheel or other similar mechanisms (see [[conduit current collection]]). The vehicle's batteries are recharged by this process—on the highway—and can then be used normally on other roads until the battery is discharged. For example, some of the battery-electric locomotives used for maintenance trains on the London Underground are capable of this mode of operation.

Developing an infrastructure for battery electric vehicles would provide the advantage of virtually unrestricted highway range. Since many destinations are within 100&nbsp;km of a major highway, this technology could reduce the need for expensive battery systems. However, private use of the existing electrical system is almost universally prohibited. Besides, the technology for such electrical infrastructure is largely outdated and, outside some cities, not widely distributed (see [[Conduit current collection]], [[trams]], [[electric (rail)|electric rail]], [[Tram|trolleys]], [[third rail]]). Updating the required electrical and infrastructure costs could perhaps be funded by toll revenue or by dedicated transportation taxes.
