Electrical Vehicle Batteries Testing in a Distribution Network Using Sustainable Energy

Abstract

EV technologies are still relatively new and under strong development. Many different designs and choices of technologies have been pursued by the automotive OEMs, battery industry and EV research centers. Although some standardized solutions are being promoted and becoming a new trend, there is an outstanding need for common platforms and sharing of knowledge and core technologies. This paper presents the development of a test platform, including three Li-ion batteries designed for EV applications and three associated bi-directional power converters, for testing impacts on different advanced loadings of EV batteries. The aim of the tests has been to study the impact of smart charging and fast charging on the power system, on the battery state of health and degradation, and to find out the limitations of the batteries for a Smart Grid. The paper outlines the advantages and disadvantages of both tests in terms of regulation of the aggregated local power, power capacity and the power exchange with the grid.Index Terms-Battery electric vehicle, battery management unit (BMU), distributed energy resources (DER), smart-grid, state of charge.

Constant Power Loads (CPL) with Microgrids: Problem Definition, Stability Analysis and Compensation Techniques

“…The first group sinks the constant value of voltage from the source regardless of the current. This type includes conventional resistive loads such as heating equipment, and inductive loads [19]. The constant current load draws a fixed current under wide variations of voltage source and has transducer and arc lamp as examples.…”

Sliding Mode Controller and Lyapunov Redesign Controller to Improve Microgrid Stability: A Comparative Analysis with CPL Power Variation

“…At this point, let us proceed to designing the corrective "control component" p*(x) so that the system classes described by (10) and conforming to (14) are stabilized by u = p 0 + p*. An approach adhering to the nominal Lyapunov function V 0 is used as the base to design the corrective control term, thus the name 'Lyapunov redesign method' is justified.…”

“…Microgrid systems offer environment-friendly distributed generation by local renewable energy resources [1][2][3][4][5][6][7][8][9][10]. From an economic aspect, it reduces the overall cost (combining the generation, transmission, and distribution) considerably.…”

Grid-Tied Photovoltaic and Battery Storage Systems with Malaysian Electricity Tariff—A Review on Maximum Demand Shaving

“…Large-scale energy storage technologies, such as thermal storage, pumped hydro storage, fuel cell storage, batteries, and supercapacitor has financial and technical limitations to be resolved [11][12][13][14]. Battery energy storage system (BESS) is receiving more attention with an increasing amount of electricity that is produced by renewable energy sources like wind and solar PV [15][16][17][18][19]. Therefore, it is vital to analyze the profitability and potential of investment in BESSs.…”
