Samsung recently announced the development of a groundbreaking solid-state electric vehicle (EV) battery (Figure 1), promising a 600-mile range, 9-minute rapid charging, and a 20-year lifespan. In contrast, EVs with conventional lithium-ion (Li-ion) batteries typically offer a 250 to 350-mile range, 25 to 30-minute rapid charging, and an 8 to 15-year lifespan. Although many major…

First-generation solid-state batteries are poised to boost the driving range of electric vehicles (EVs) by 50% to 80%. Solid-state batteries could extend this range even further, with some automotive manufacturers ambitiously targeting 900 to 1,000 miles per charge. This article reviews how solid-state technology increases EV battery capacity and range, discussing lighter and more energy-dense…

Lithium-ion (Li-ion) battery traction packs power most electric vehicles (EVs) on the road today. These batteries enable electric motors to efficiently generate the high torque required for rapid acceleration and consistent speeds. Although Li-ion batteries offer high energy density and a relatively long lifespan, many automotive companies are actively researching and developing solid-state battery technology.…

Many automotive manufacturers classify new cars and trucks as software-defined vehicles (SDVs). As SDVs by design, electric vehicles (EVs) optimize vital systems and functions with sophisticated artificial intelligence (AI) and machine learning (ML) capabilities. This article discusses AI’s crucial role in EVs, from smart charging and advanced driver assistance systems (ADAS) to predictive maintenance and…

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…

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…

The US Department of Energy (DOE) today announced more than $131 million for projects to advance research and development (R&D) in electric vehicle (EV) batteries and charging systems and funding for a consortium to address critical priorities for the next phase of widescale EV commercialization. The advanced battery consortium will work towards developing advanced technologies…

TTape from Littelfuse, set of temperature-triggered switches, raises a bit that indicate hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write…
