Smart Hubs 1 - A Demonstration of Electric Vehicle’s Lithium - Ion Battery Charging Characteristic and Efficient Demand Side Energy Management with Solar Photovoltaic System

The world is transitioning to clean energy sources, and electrifying the automotive sector is viewed as one of the solutions to achieve a set target in emission reduction. This paper reports a research investigating the energy mismatch in a network integrating electric vehicle (EV), battery energy storage system (BESS), and solar photovoltaic (PV) array with a flexible energy management system (EMS). Electric vehicle (EV) is being tested in terms of DC fast charging to understand the charge and discharge regime and its impacts on the network infrastructure, and the energy interchange in the distribution network system, while maintaining energy efficiency. A detailed description of the system structure, the connected subsystems and the emulation of subsystems for testing purposes with the interfacing and safety consideration is outlined in the paper. Test results are extensively discussed in the paper and results show the effectiveness of a regulated DC-bus in developing EV fast chargers.
