In addition to the highperformance control systems needed, switching and curving of the tracks becomes difficult with linear motors, which to date has restricted their operations to highspeed point to point services. Leadacid batteries in EV applications end up being significant 2550 portion of the final vehicle mass. The vehicle, initially known as the iCar, is called the Chevrolet This yields cells with an impressive 160Whkg energy density and good power density, and near lossless chargedischarge cycles.
Recent advances in battery efficiency, capacity, materials, safety, toxicity and durability are likely to allow these superior characteristics to be applied in carsized EVs. The sodium or zebra battery uses molten chloroaluminate NaAlCl4 salt as the electrolyte. Since the battery must be heated for use, cold weather doesnt strongly affect its operation except for in increasing heating costs. This allows for almost no rolling resistance of the vehicle and no mechanical wear and tear of the train or track.
The Tesla Roadster uses blades of traditional lithiumion batteries include short cycle lifes hundreds to few thousand charge cycles and are nontoxic. Lithiumion and similar lithium polymer batteries, widely known through their use in laptops and consumer electronics, dominate the recent group of EVs in development. The traditional lithiumion chemistry involves lithium cobalt oxide cathode and graphite anode. The technology is old and well established see Conduit current collection, Nickeliron battery.
The vehicle, initially known as the iCar, is called the Chevrolet The infrastructure has not been built. In the systems above motion is provided by rotary electric motor. The cathode is also somewhat toxic. The average distance driven by 80 of citizens per day in car in the US is about miles US dept of transport, 1991, which fits easily within the current range of the vehicle, allowing it to be driven until it can be fully charged by plugging it into standard household AC electrical source.

This range can be improved by technologies such as Plugin hybrid electric vehicles which are capable of using traditional fuels for unlimited range, rapid charging stations for BEVs, improved energy density batteries, flow batteries, or battery swapping. In GM began the development of plugin EV that will use lithiumion battery. The cathode is also somewhat toxic. Levitation and forward motion are two independent effects the forward motive force normally requires external power, although some types, such as Inductrack, achieve levitation at low speeds without any.
