This article is contributed by Jai Makhija Image source: Unsplash/Hyundai Motor Group A battery thermal management system is required to allow the next generation of electric vehicles (EVs) to compete with internal combustion engine (ICE) powered vehicles in terms of range, lifetime and fast charge. Computational Fluid Dynamics (CFD) can…

This story is contributed by Charlie Parker and Dr. Nemanya Sedoglavich Price declines as a function of learning rate are typically perceived to be due to economies of scale but technology and native technology development play a more foundational role. As new and niche industries scale, novel innovations become further…

Most alloying anodes, such as silicon, tin, and germanium, have higher gravimetric and volumetric capacities than graphite. Alloying anodes face challenges to adoption, however, due to the large volume changes that typically accompany the alloying mechanism, changes that have negative consequences at multiple levels of the battery. Most of the…

India’s EV origins Like every EV origin story, the Indian one has an unlikely star: the Lovebird. The Lovebird was created in Chalakudy in the state of Kerala, home to Eddy Current Controls. Eddy still proudly displays the vehicle on its website, but Eddy has only ever sold a handful of units. …

Because of the intermittent nature of renewable generation, long-duration storage at low costs is needed to decarbonize the electrical grid. Due to the fact that renewables have a near zero marginal cost of energy production, there is enormous opportunity for energy storage systems, which can offer load shifting, peak shaving…

This article is contributed by Singyuk Hou While a graphite anode works by intercalating lithium into the interstices between the layer structure, a silicon anode reacts with lithium via intermetallic alloying, which gives silicon the potential to store ten times more lithium than graphite for a 30% increase in the…

This story is contributed by Dhevathi Rajan Rajagopalan Kannan Fast charging is critical for the adoption of electric vehicles (EV’s), but higher current charging typically comes at the expense of battery life. Multistage constant current (MCC), pulse charging, boost charging, and variable current profiles (VCP) are among the fast charging…

This article is contributed by Luke Workman and Electric Goddess Corrosion is the primary cause of failure in vehicle battery packs during their long service periods. If batteries are not adequately protected from corrosion, they will be vulnerable to failure, including catastrophic thermal events. Corrosion risk can be greatly reduced…
