A low cost energy usage recording and billing system for electric vehicle

As conventional fuel resources are dwindling, electric vehicles are emerging as the only viable alternative to petrol, diesel and gas based vehicles. However, the biggest stumbling blocks in the proliferation of electric vehicles is the issue of conveniently charging electric vehicles. In this paper, a smart, low cost ac charging system for electric vehicles is discussed. This is accomplished by having a two-part system in which one part deals with the operation of dispensing electric energy and displaying usage and the other part looks after operations such as billing, storing usage data, customer information etc.
