To charge an all types of Electric Vehicles (EVs) is the most primary part of the electrical vehicle industry. Nowadays charging communication between vehicle and
charging station becoming more and more popular. Automotive industries are trying to charge vehicles in minimal time and also the secured one. In the charging
communication scenario, current is flowing through the charging station to the EV through electric line and normally communication between them takes place with
the help of Controller Area Network (CAN), Wi-Fi and Powerline Communication (PLC) etc. There are two types of charging communication available in the current
industry: High level and Low level communication for Alternating Current (AC) and Direct Current (DC). Low Level Communication (LLC) uses only Pulse
Width Modulation (PWM) signals to transmit data, which is analog signals. On the other hand, High level Communication (HLC) provides digital and IP network
based communication. These both types also support many different standards for communication. For example, ISO 15118, IEC 61851, DIN 70121 and many more.
These standards have the message sequences for the flow of charging and also their implementation.
The goal of this thesis is the development of low cost EVSE test system, which has the PLC technology with up to 10 Mbps data rate and two different standards for
charging communication with HLC. This thesis proposes an implementation between a communication controller or SECC of Electric Vehicle Supply Equipment (EVSE)
side and Signal Level Attenuation Characterization (SLAC) in PLC modem. SLAC functionality helps to overcome the problem of crosstalk while charging. In this
work, there will be a test system with SECC and PWM generator, some resistors to identify proper lock mechanism between charging cable and vehicle inlet, the ISO
15118 and IEC 61851 for PWM signals. Implementation of SECC will be in JAVA language and each message executed in XML script language. Our examination
shows this approach very remarkable low cost AC based test system with digital communication system, which can help to test direct or virtual EV or HiL system.
