Electric vehicle battery to recharge at home without extension cord). Features of swap stations include: Concerns about swap stations include: Zinc-bromine flow batteries can be re-filled using a liquid, instead of recharged by connectors, saving time. Three companies are working on battery lease plans. Greenstop has completed trials of their ENVI Grid Network which allows consumers to easily monitor and recharge electric vehicle batteries. Think Car USA plans to lease the batteries for its City electric car to go on sale next year. Better Place is creating a system for consumers to "subscribe" to a service that offers recharging stations and battery exchange.
