BACKGROUND ART Electric vehicles (EVs) such as plug-in-hybrid electric vehicles (PHEVs) have recently become an issue because they have advantages such as low energy consumption and low air pollution . Electric vehicles play an important role in addressing environmental pollution and energy conservation, especially in the paradigm of smart grid.

Because of the nature of the electric car, the electric car owner can charge his car at a taxi stand, parking lot, public phone booth, driveway, or house garage. In addition, electric vehicle owners can charge their cars at air stations such as gas stations.

Generally, there are two types of electric vehicle charging control systems, such as a distributed coordination system and a centralized coordination system, for charging electric vehicles.

The distributed charge control system includes a charging station in a home or office, or a public charging station. For charge management in a distributed charge control system, a home energy control box or smart charger must be integrated into the network of stand-alone home charging stations and home charging stations.

If the charger is network connected, monitoring the information exchanged between the charger and the charging control system of the electric vehicle is important for fault analysis and management of the entire charging system.

Accordingly, in recent years, research on monitoring data transmitted and received between a charger and a charging control module (CCM) installed in a vehicle has been actively conducted.

Conventionally, simulator-based equipment has been released to test the communication performance between charger and electric vehicle such as Auronic's DC.chargeStressor and Enterop Test System.
