Some embodiments disclosed herein include systems and method for verifying meter accuracy. The system may include an electric vehicle charging station that includes a submeter that measures an amount of energy discharged from the electric vehicle charging station and to a connected electric vehicle. A meter test device may also be connected to the electric vehicle charging station to determine the accuracy of the submeter in local time.

Systems and methods for verifying sub metering accuracy for electric vehicle charging stations

An electronic device configured to switchover power from a primary source to an alternate source to maintain continuity of power supplied to a load bus. The electronic device includes one or more processors configured to identify availability of the alternate source using source monitoring in order to measure and calculate a tracking frequency for controlling a variable sampling interval of the one or more processors. The processors are configured to store signal samples and associated time stamps into a variable length buffer and store new sample values and associated new time stamps into the fixed length buffer. The processors are configured to determine attributes from samples of the alternate source using the tracking frequency. The processors are configured to execute a source switchover signal when the primary source is unavailable based by comparing load bus attributes to alternate source attributes at an estimated instance of switchover.
