Abstract
A method and system provide for the cooperative charging of electric vehicles. By using power line communications, chargers of the electric vehicles who are serviced by the same distribution transformer can form self-contained local area networks due to the nature of power line communications (PLCs). Alternatively, or in addition to the PLCs, other communication networks, such as the Internet and local area networks, may be used as part of the communications infrastructure for the chargers. After the chargers of the electric vehicles are coupled to one another through power line communications or traditional communications networks, they can form a logical token ring network. According to this token ring network, a predetermined number of tokens can be assigned within the token ring network for permitting chargers with tokens to charge respective electric vehicles while chargers without tokens must wait until they receive a token to initiate charging.
