Abstract

The existence of Public Electric Vehicle Charging Stations (SPKLU) is increasing alongside the rise in electric vehicle usage in a certain area. EVCS is equipped with devices that directly interact with electric vehicles (EVs) during charging; this device is called Electric Vehicle Supply Equipment (EVSE). Both EVSE and EV require protocols to communicate with each other aimed at exchanging information such as readiness for charging between EVSE and EV. The communication protocol used in this research is the SAE J1772 protocol. This study focuses on designing a hardware prototype of EVSE based on the principles of the J1772 AC Type 1 connector as the transmission medium to electric vehicles (EVs). The design of EVSE communication simulation uses the Falstad Circuit Simulator platform, and the PCB layout design uses the EasyEDA platform. The hardware prototype of EVSE is controlled using a Raspberry Pi 3B mini PC as the core management, then integrated with the initial terminal block, power supply block, PZEM-004T sensor module, J1772 communication block, 2-channel solid-state relay (SSR) module, and J1772 terminal.

Abstract

Electric energy can be utilized as an alternative to replace oil-based fuel. One of the steps to address the energy crisis issue is through the Energy-Efficient Car Competition (KMHE), which emphasizes the energy efficiency of vehicles. The WEIMANA team from Udayana University has participated in the Urban Concept category by designing a vehicle named Agnijaya. Agnijaya is an electric-powered car that uses a Brushless DC (BLDC) electric motor. Currently, the Agnijaya electric car does not have a continuous monitoring system for voltage, current, and speed. The research aims to design a monitoring system for the Agnijaya electric car using an SD card as a data storage medium for voltage, current, and speed data. This system is controlled using an Arduino Mega 2560 Pro Mini microcontroller board as the data processor and an SD card as the data storage medium. The monitoring system for the Agnijaya electric car has been successfully designed, built, and tested for voltage, current, and speed values. Testing was conducted by comparing the measured values of voltage, current, and speed, all of which were stored on the SD card. The results of the analysis indicate that the percentage deviation in battery voltage measurement is 0.85%, the deviation in battery current measurement is 0.23%, and the deviation in speed measurement is 0.32%.
