Equipment performance evaluation method and device, storage medium and terminal

The invention discloses an equipment performance evaluation method and device, a storage medium and a terminal, relates to the technical field of intelligent power utilization and metering, and mainly aims to solve the problem that the performance of electric vehicle indoor charging behavior identification equipment cannot be evaluated. The method mainly comprises the steps that first measurement data and second measurement data are acquired, the first measurement data are actual load parameters measured by standard equipment according to all preset charging stages, and the second measurement data are load parameters measured by equipment to be evaluated according to all preset charging stages; determining an identification difference degree between the first measurement data and the second measurement data; and correcting the identification difference degree based on a penalty coefficient and a superposed electric appliance weight coefficient, and determining a performance evaluation result of the to-be-eval
