Patent number: 12202369Abstract: An integrated meter in an electric vehicle supply equipment (EVSE) is described. Input power is received at input terminal of the EVSE and carried through a conductor that passes through an opening of a current transformer coil of the meter. The input power is split into a main path and an auxiliary path. The main path is for charging an electric vehicle (EV). The auxiliary path provides power to the meter to the EVSE itself. The auxiliary path passes through the opening of the current transformation coil in a reverse direction before being passed to a power supply of the meter and to a power supply of the EVSE to remove any current not for charging the EV from current measurements. The meter calculates energy measurements that do not include current drawn by the meter and the EVSE and transmits them to a processor of the EVSE.Type: GrantFiled: February 15, 2024Date of Patent: January 21, 2025Assignee: CHARGEPOINT, INC.Inventors: David R.
