Charging

A new integrated battery test system combines environmental chambers, cyclers, and fixtures into a single, pre-configured unit, designed to reduce setup and integration time. The system combines hardware and control software from Associated Environmental Systems (AES) and MACCOR Inc., allowing test facilities to begin operations shortly after delivery rather than waiting through traditional multi-vendor integration…

For organizations that depend on large vehicle fleets, electrification offers the potential to reduce fuel and maintenance costs while also cutting emissions. Beyond consumer electric vehicles (EVs), it requires designing charging systems capable of supporting high duty cycles, integrating with facility power infrastructure, and maintaining reliability under demanding operating conditions. And this transition is already…

Electric vehicle (EV) engineering is defined as much by what cannot be seen as by what can. The “gaps” or unseen spaces between battery cells, slot die coating of electrode layers, cooling plates, electric motor housings, and composite joints have a significant influence on performance, safety, and durability. Managing these dimensions with high accuracy has…

Electric vehicle (EV) motor design continues to evolve as manufacturers target higher power density, greater efficiency, and seamless system integration. This article reviews optimization strategies for EV motors, focusing on material innovations, control algorithms, and thermal management. It also highlights emerging testing protocols and safety standards that ensure reliable operation and support integration across next-generation…

Reconfigurable battery packs dynamically adjust internal connections, voltage, current distribution, and power output.  Unlike conventional fixed packs, they isolate faulty cells, balance power loads, and respond to dynamic energy demands. These capabilities are increasingly important for electric vehicles (EVs), as well as renewable energy storage and smart grid infrastructure. This article explores the key functions…

Lithium plating is the deposition of metallic lithium on the surface of the anode in a lithium-ion battery. The process is considered one of the most severe aging mechanisms in these types of batteries, and it can shorten the battery’s life and rapidly reduce its capacity. This article will discuss how anode design, anode materials,…

U Power Limited, a provider of AI-powered solutions for energy grids and electric vehicle (EV) transportation systems, announced the signing of a Memorandum of Understanding and Business Cooperation Agreement with IoTeX, a blockchain platform focused on transforming machine-generated data into collective intelligence for AI. The agreement builds on U Power’s proprietary UOTTATM battery-swapping technology for…

Most of the automotive industry still relies on standard metrics such as cycle life and energy density to evaluate electric vehicle (EV) battery performance. While useful for benchmarking in controlled settings, these metrics often fail to reflect the complexity and variability of real-world operation. This article explores the limitations of conventional EV battery metrics, from…

This article examines the primary functions of reconfigurable EV battery packs, concentrating on technologies such as active switching, selective balancing, and dynamic load management.

After decades of iteration, the lithium-ion battery industry faces a fundamental crossroads. While chemistries and materials have evolved, the core battery architecture has remained largely unchanged since its introduction more than 30 years ago. But as demand grows for safer, more affordable, and higher-performing batteries, especially for electric vehicles (EVs), cracks are beginning to show…
