Sodium-ion batteries: the future of sustainable energy storage
Lithium-ion batteries (LIBs) have become essential for energy storage systems. The limited availability of lithium, however, has raised concerns about the sustainability of LIBs. In a new study, scientists from Dongguk University reviewed the recent advances in sodium-ion battery technology, a potential alternative to LIBs. Their findings can inspire young researchers to combat the current…
What is an EV battery state of charge (SOC)?
An electric vehicle (EV) battery state of charge (SOC) represents energy levels as a percentage. Analogous to an internal combustion engine (ICE) fuel gauge, SOC clearly indicates available energy that directly corresponds to the driving range. This article explains how SOC is calculated and explores the different methods used to determine these calculations. It also…
What is a lithium battery digital passport?
A digital battery passport provides easy access to structured, reliable, and complete information about the battery. This fresh initiative in the US lithium battery landscape aims to simplify consumers’ choice and use of batteries. The US government agencies are working on battery passport requirements, centralizing battery specifications and pertinent details, making it user-friendly for the…
October 2023 Issue: Power & Energy Efficiency Handbook
Engineering a green mindset and sustainable future Growing up in the pre-2000s era with a power electronics engineer for a father, my family’s first introduction to power and energy efficiency efforts was primarily analog. The word “vampire” was associated with a TV show called Dark Shadows; it had nothing to do with standby power…
Battery testing: critical to the rise of electric vehicles
When designing a battery into an EV, you must perform rigorous testing to understand a battery’s performance. Electric vehicles (EVs) accounted for 13% of global vehicle sales in 2022 and are forecasted to reach 30% of global vehicle sales by 2030. The industry needs to continue working on making EVs affordable to support this transition…
Testing batteries for an evolving world
Battery testing enables vehicle manufacturers, owners, and researchers to make informed decisions, optimize vehicle performance, and enhance overall user experience. Demand for electric vehicles is amping up. Every one of these vehicles needs large batteries, and the industry is responding by building plants. Energy.gov forecasts that by 2030 electric vehicle battery manufacturing capacity in North…
