Combined with the fault degree, maintenance experience, and expert analysis of the charging pile, the state classification strategy is given. Each indicator of the charging pile is standardized according to the threshold level of the operating state.
However, the operation parameter data resources of the charging pile are limited, and cannot be further supplemented and improved according to the actual station operation scenario to obtain a more comprehensive and stable state evaluation or prediction.
These problems can be prevented by energy storage systems (ESS). Levelling the power demand of an EV charging plaza by an ESS decreases the required connection power of the plaza and smooths variations in the power it draws from the grid.
Each indicator of the charging pile is standardized according to the threshold level of the operating state. According to the advantages and disadvantages of the operating parameters, it can be divided into four risk levels: health, normal, minor failure, and serious failure.
Comparison of risk consequences of three models. The risk consequence of preventive maintenance decision of electric vehicle charging pile is actually the load loss value.
Charging model of the DC charging pile. On the left is the off board charger (i.e., DC charging station), and on the right is the electric vehicle, which are connected through vehicle plugs and sockets.
