Summary:

This paper introduces a modeling and experimentation methodology for transient analysis of surge protective devices (SPDs) for electric vehicle charging system (EVCS) application. The suggested Surge Protective Device topology is to shield the EV power electronics such as on board charger from surge events generated by the grid during charging, with implementation on the grid-EV interface. A new surge protection circuit is designed to suppress transient overvoltages, with its performance evaluated through simulation. The SPD is evaluated in SPICE simulator in the time domain, including its nonlinear spark over characteristics along with its resistive, capacitive and inductive effects. Equivalent circuit is developed and evaluated by simulation under typical surge conditions. The outcomes prove the topology to be effective in clamping voltage, reducing energy transfer to the EV side, and achieving surge event detection. The contribution of this work lies in the establishment of dependable and smart surge protection systems for secure and resilient EV charging infrastructure
