Next-Gen Batteries Require Impedance Data And Active Balancing
By Liz Allan - 07 May, 2026 - Comments: 0

Key Takeaways Electric vehicles and energy storage systems using LFP batteries require more sophisticated diagnostic methods because they exhibit very flat cell voltages across various charge levels, making it harder to estimate usable energy. Battery management systems are leveraging new components, AI/ML, digital twins, and other techniques to get more accurate, real-time data, includ... » read more

Batteries Charge To The Edge
By Ed Sperling - 20 Apr, 2026 - Comments: 1

Long-awaited advances in battery chemistry and materials science are beginning to roll out, opening the door for higher capacity, faster charging, and much lower likelihood of thermal runaway. This is a high-stakes race, fueled by an insatiable demand for power everywhere from handheld devices to data centers. When Finland's Donut Lab claimed earlier this year that it had developed a solid-s... » read more

Moving Electrons, Not Just Vehicles
By Liz Allan - 02 Apr, 2026 - Comments: 0

Key Takeaways: There are several ways to convert AC power from the grid to DC power in the system. Some degrade the battery faster than others. Battery management systems monitor cell voltage, current, and temperature, helping to estimate state of charge, health, and useful remaining life. A PMIC with a multi-level converter is the most efficient way to get power from the battery to ... » read more

Batteries Look Beyond Lithium
By Bryon Moyer - 07 Nov, 2024 - Comments: 1

Lithium batteries dominate today’s rechargeable battery market, and while they have been wildly successful, challenges with lithium have spurred research into alternative chemistries that can improve on some of lithium’s downsides and still keep as many of the upsides as possible. So far, none of the alternative batteries has seen commercial success, but several variants have moved beyon... » read more

The Challenges Of Upgrading Lithium Batteries
By Bryon Moyer - 12 Sep, 2024 - Comments: 0

The ongoing electrification of everyday items has resulted in the proliferation of batteries, and spurred continued development for automotive and grid use. Lithium-ion batteries still dominate the rechargeable-battery landscape, with solid-state versions prolonging that position, but other lithium variants aim for greater safety while raising energy capacity. Battery researchers must balanc... » read more

Distributed Batteries Within a Heterogeneous 3D IC
By Technical Paper Link - 12 Mar, 2024 - Comments: 0

A new technical paper titled "On-Chip Batteries as Distributed Energy Sources in Heterogeneous 2.5D/3D Integrated Circuits" was published by researchers at University of Florida (Gainesville) and Brookhaven National Lab. Abstract "Energy efficiency in digital systems faces challenges due to the constraints imposed by small-scale transistors. Moreover, the growing demand for portable consum... » read more

Powering Up Electric Heavy-Duty Vehicles
By Hwee Yng Yeo - 26 Oct, 2023 - Comments: 0

Smokey tailpipe emissions may soon be a thing of the past, as the heavy transport vehicle market catches up with the electric car market to lower their contribution to greenhouse gas (GHG) emissions. Private sedans and light-duty trucks lead the vehicle electrification race, leaving much upside opportunity for heavy transport fleets such as trucks and buses to catch up. In the United Stat... » read more

Research Bits: September 11
By Jesse Allen - 11 Sep, 2023 - Comments: 0

Combining digital and analog Researchers from École Polytechnique Fédérale de Lausanne (EPFL) propose integrating 2D semiconductors with ferroelectric materials for joint digital and analog information processing, which could improve energy efficiency and support new functionality. The device uses a 2D negative-capacitance tungsten diselenide/tin diselenide tunnel FET (TFET), which consu... » read more

BMS: The Guardian Of Battery Health And Security
