Attendees of this year’s Battery Show in Novi, Mich., could be excused for not knowing what to expect on the show floor as trade events start to come back from a year-and-a-half hiatus. The above clip gives a glimpse of what the experience was like. Aside from the occasional mask wearer, it seemed like business […]

Nanopower primary cell monitor incorporates precision coulomb counter
Analog Devices, Inc. new LTC3337 is a nanopower primary (non-rechargeable) cell State-of-Health (SoH) monitor with precision coulomb counter, designed to be placed in series with a primary battery with minimal associated series voltage drop. The patented infinite dynamic range coulomb counter tallies all accumulated battery discharge and stores it in an internal register accessible via […]
Battery safety standards and testing
Lithium-ion battery (LIB) safety is a major concern for designers. LIBs are generally safe to use if they have been properly manufactured and are integrated correctly into systems. However, the use of sub-standard materials and the possibility of manufacturing or design defects can result in hazardous conditions. As a result, there are many global safety […]
Battery management system targets robotics, AGV, 2/3-wheeler apps
The new i-BMS Battery Management System from Lithium Balance, acquired by Sensata earlier in the year, is a cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60 V, such as two and three-wheelers, automated guided vehicles (AGVs), and robotics. The i-BMS is a long-term solution for customers who […]
Battery pack protection keeps EVs on the road
A few best practices for handling transients and over-currents help make electronic drivetrains more reliable. James Colby • Littelfuse, Inc. Automotive market analysts predict that by 2025, high-end vehicles will contain more than $6,000 in electronic components. Most of these advanced electronics will be in the growing number of electric vehicles (EVs). To ensure robust, […]
Say goodbye to cross-country road trips
Leland Teschler • Executive editor Officials estimate it will cost $50 billion to field the chargers needed for the expected number of electric vehicles on U.S. roads by 2030. But it’s possible that spending every penny of this amount won’t prevent the extinction of the cross-country road trip. Here’s the logic behind that statement: It’s […]
Energy storage by the Farad, Part 3: Hybrid supercapacitors
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. Just as with rechargeable batteries, supercapacitors need proper management to optimize their performance and avoid mishaps. In many ways, the supervisory requirements for both are similar but there are some differences. Vendors of power-management ICs […]
Energy storage by the Farad, Part 2: Supercapacitors & batteries
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. The previous part of this article established the context for supercapacitors and explained their structure in simplistic terms; obviously, this is a component with deep physics, chemistry, materials-science considerations, and manufacturing issues. The first widely […]
Fuses for space apps boast static-dissipative polyester packaging
SCHURTER has improved the packaging of its space fuse series MGA-S, with an enhanced dissipative structure on the outer layer of the ESD bag. The outer layer of the old packaging was aluminum with abrasion-resistant coating. The material of the outer layer of the new packaging is a static-dissipative polyester. The MGA-S is hermetically sealed […]
Interactive sizing selection guide covers surge protective devices
Littelfuse, Inc., announced today the launch of a surge protective device (SPD) selection guide that sizes SPDs to achieve the best level of protection for a system based on specifications provided. Surge protective devices need to be sized correctly. If they are sized too low, the system could be susceptible to temporary overvoltages as well […]
