ELECTRICAL ENERGY CHARGING SYSTEM AND METHOD FOR CHARGING A VEHICLE
First Claim
1. Electrical energy charging system for a vehicle comprising a charging station (2) on a charging energy source side and a vehicle unit (12) on a charging energy receiver side, characterized in that the system comprisesan identification system configured for identification of a charging energy receiver identity (11);
- a charging energy meter system comprising a first energy meter (5) on the charging energy source side and a second energy meter (6) on the charging energy receiver side for measuring outgoing charging energy Eout from the charging energy source side and incoming charging energy Ein to the charging energy receiver side, wherein the energy meters (5, 6) are constructed such that they create communicateable values comparable to each other and that they provide a reasonable estimation of the momentarily transferred energy;
a communication system configured for transfer of the charging energy receiver identity (11) and continuous transfer from the charging energy receiver side to the charging energy source side of data regarding amount of measured incoming charging energy on the charging energy source side for comparison with the outgoing charging energy measured at the charging energy source side, wherein the result of this comparison is decisive whether the charging energy source side shall continue to provide energy to the charging energy receiver side or not.
