Abstract
To minimize the greenhouse effect caused by emission of CO2, many automobile manufacturers are developing battery-powered automobiles that typically use re-chargeable lithium polymer (or ion) batteries. However, the future of these battery-powered electric cars is less than certain. The re-chargeable lithium batteries are heavy and expensive with a limited life. Furthermore, Earth has only about 10 million tons of lithium, enough to put one battery system in each vehicle in use today worldwide. This chapter presents a new design concept for an alternate electric car – On-Line Electric Vehicle (OLEV). OLEV draws its electric power from underground electric coils without using any mechanical contact. The maximim efficiency of power transmission over a distance of 17 cm is 72%. OLEV has a small battery, which enables the vehicle to travel on roads without the underground electric coil. Batteries are recharged whenever OLEV draws electric power from the underground coils and thus, do not require expensive separate charging stations. The infrastructure cost of installing and maintaining OLEV is less than those required for other versions of electric vehicles. This chapter presents the overall design concept of OLEV.
