The continuing efforts to decarbonize power generation include massive deployment of electric vehicles, PV plants and wind farms to reduce dependence on fossil fuels. Battery storage and charging infrastructure are cornerstones of these efforts, with the annual demand of lithium-ion batteries expected to reach 800GWh/year by 2025. The next generation of large power electronics converters (AC/DC and DC/DC) are crucial to realize the rapid deployment of 1000V battery energy storage systems in renewable power plants, utility scale backup systems, and EV bulk charging stations. Key requirements include compact, lightweight, modular systems with remarkable intelligence. These features will allow easy transportation, deployment, parallel connection (very high power) of new 1000V battery charging systems while enabling optimal power flow and high efficiency operation.The objective of the collaboration between Dr. Ordonez at the University of British Columbia and Alpha Technologies (an EnerSys company), is to develop the next generation of power electronics conversion systems for battery energy storage with high efficiency, high power density, and wide output regulation. Alpha Technologies Ltd., one of the top high-tech employers in BC, is a leading company in powering solutions and EnerSys (parent company) is a global company with ~20% of the global battery storage market.This R&D project combines novel semiconductor devices (wide-bandgap), advanced passive components and heat management, novel topologies, and control methods to enhance regulation and efficiency, and system-level functions such as predictive maintenance to reduce the size, improve efficiency, and increase reliability of new 1000V charging systems. With the development and incorporation of these core technologies, the growing energy storage, renewable energy, electric vehicle, and telecommunications industries will access major technological advantages and accelerate their deployment. The project aligns with the government of Canada's initiatives to promote energy efficiency and clean energy technology.
