Abstract
Testing of electric vehicle charging stations (EVCS) is performed. In an active mode, the device provides or is connected with a programmable load capable of emulating the load of an electrical vehicle (EV). In passive mode, the load is an EV with the device being arranged in series between the EVCS and EV. In either case, energy delivery from the EVCS to the load is monitored by the device to determine energy measurement and billing accuracy of the EVCS. This enables a comparison to be made between a measured value of energy delivered and a metered value of energy delivered as given by the EVCS. Other measurements and safety tests may also be performed by the device. A programmable load controller is also provided for providing a variable effective load as seen by the EVCS based on one or more fixed loads.
