Battery technology is the foundational element of electric vehicles (EVs), influencing their efficiency, range, charging speed, lifespan, cost, and overall performance. Engineering firm Bosch Rexroth is well aware of how battery manufacturing affects every one of these factors. It believes innovations in battery technology and advanced manufacturing processes are essential for the widespread adoption and…

The electric vehicle (EV) battery supply chain is vast and complex, spanning mining and processing to assembly and end-of-life management. This article reviews the supply chain’s four primary stages: upstream, midstream, downstream, and recycling or repurposing. It also highlights major supply chain challenges and explores potential solutions to improve resiliency, efficiency, and sustainability. Defining the…

by Luca Vezzadini, ZIVAN The urgency of mitigating climate change and reducing greenhouse gas emissions has prompted businesses to adopt more sustainable transportation solutions, particularly electric vehicles (EVs). Lithium-ion batteries (LIBs) are at the forefront of electrification. McKinsey predicted that the entire LIB chain, from mining through recycling, could grow by over 30% annually from 2022…

In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using…

Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging batteries that don’t compromise energy density. Lithium plating for ultra-fast charging raises safety concerns due to high cell polarization, requiring careful attention. During fast…

In this article, we’ll explore the types of e-bikes available and their features. In terms of e-mobility, e-bikes stand out as a compact, affordable option for many.

Editor’s note: Read more and watch colleague James Anderton on engineering.com TV describe what this “nuclear battery” means to you and me and the charging cords we carry — or not.  Check it out here. Beijing’s Betavolt New Energy Technology Co., Ltd. announced a miniature atomic energy battery that combines nickel 63 nuclear isotope decay…

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…

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…

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…
