<p>A method of charging an electric vehicle battery using the following electrical connections: a first plug (3, Fig. 8) mating with a first socket (3, Fig. 8) on the vehicle (200, Fig. 8); a second plug (400, Fig. 8) mating with a second "mains power" socket (44, Fig. 8); and a cable (7, Fig. 8) connecting the plugs; the charging system also comprising a control means comprising an electronic memory device. At least one electrical connection comprises temperature sensing means (412U, 412E, 412L, Fig. 7), mounted close to electrical conductor(s) within the plug or socket. The method comprises: measuring the temperature of the connection during charging; comparing said temperature with preset thresholds held in the electronic memory; and varying the current drawn by the battery from the electrical supply to maximize the charging rate without allowing the plug or socket to get too hot.</p> |
