SYSTEM AND METHOD FOR CONSUMPTION METERING AND TRANSFER CONTROL

摘要

A method and system for metering energy consumption in a system comprising a mobile unit 110, the mobile unit comprising a position sensing means GP, a metering unit SMT for measuring energy consumption in the mobile unit, and a network access device NAD for communicating over a mobile network, MNW, 116; a distribution system operator, DSO, 107 distributing energy from an energy service provider, ESP 109, to a consumption location CL, 105; an energy transfer validation system, ETVS, 102 for managing and validating transferral of energy to mobile units and comprising a database with a mapping of consumption locations, CL, 105 with geographical positions PS is provided. The method comprising the steps of - coupling 1 the mobile unit to a CL; - transferring energy 10 to the mobile unit, - the mobile unit transmitting 2 a consumption location request message CONS_LO_REQ with information aimed for at least the ETVS, the information comprising the identity of the mobile unit, EV_ID, and a resolved position, PS, of the mobile unit; - the ETVS resolving 4 at least one CL identity, CL_ID, or a list of possible CL identities, CL_ID's, from the resolved PS or from a last known PS, - the ETVS transmitting 5, 6 a consumption location list message CONS_LO_LIST comprising the at least one resolved CL_ID and the DSO_ID with which the at least one CL is associated - or - the consumption location list message comprising a list of possible resolved CL_ID's and the respective DSO_ID's associated with resolved CL_ID's, wherein information related to the consumption location list message CONS_LO_LIST is being aimed for at least the mobile unit; - upon the energy transfer being completed or interrupted, the mobile unit transmitting 12 a consumption report CONS_RPRT aimed for at least the DSO.
