High-voltage contactors support lithium-ion battery switching up to 1000 V DC
TDK Corporation has introduced two new high-voltage contactors designed for use in demanding applications. The HVC43MC integrates a mirror contact for position detection, while the HVC45 offers increased short-circuit current handling capability. These components support systems operating at up to 1000 V (DC), making them suitable for lithium-ion battery switching in traction applications, energy storage…How could advances in solid-state batteries impact EV charging designs and requirements?
Batteries are a key element in electric vehicles (EVs), and there has been a lot of development in solid-state and other EV battery chemistry. This FAQ will highlight the promising materials that align with solid-state and other EV batteries, making them suitable for EV batteries. Material advances in solid-state batteries In solid-state batteries, sulfide, oxide,…IC improves lithium-ion battery protection for automotive applications
ABLIC has introduced the S-19161A/B integrated circuit (IC) designed to support the miniaturization of backup power systems in automotive applications. This new IC enables vehicle manufacturers to replace multiple nickel-hydride batteries with a single lithium-ion battery in emergency backup systems, offering the same functionality in a more compact design. The S-19161A/B operates in extreme temperature…What joining methods optimize EV battery production efficiency? part 4
This final part of the multipart FAQ will explain the mechanical assembly and soldering process used to make joints during electric vehicle (EV) battery production. Although these two mechanisms are somewhat primitive in nature, they still find applications for making low-cost EVs where the makers do not have access to automation and advanced technologies. Mechanical…What joining methods optimize EV battery production efficiency? part 3
This third part of the multipart FAQ will discuss magnetic pulse welding, micro-TIG, and clinching for electric vehicle (EV) battery productions. While the first two mechanisms use high temperatures to make joints, the clinching mechanism is based on applying force to create mechanical interlocking to create joints. All three mechanisms are less popular than the…What joining methods optimize EV battery production efficiency? part 2
Resistance spot welding and wire bonding are popular choices for creating joints during EV battery production. However, every joining technology comes with a trade-off, giving packaging engineers room to select the appropriate one for their battery design. This is the second part of the multipart FAQ on the joining methods for EV battery production and…Stationary Power See More >

How does MBSE work for EV and stationary battery energy storage systems?
Model-based systems engineering (MBSE) is comprehensive. The International Council on Systems Engineering (INCOSE) defines MBSE as the “formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.” It’s especially applicable to complex systems of systems like…

GPS/GNSS antennas achieve 200 cm positioning accuracy.
Taoglas announces a new family of active, multi-band GNSS antennas. Levity Series’ AHP24510 (L1/L2/L-Band) and AHP54510 (L1/L5/L-Band) directional patch antennas are optimized for GPS, Galileo, GLONASS, and BeiDou satellite constellations. Triangulation across several satellites provides faster and more accurate acquisition and lock onto signals, particularly in built-up areas. The L-Band capability means Levity Series antennas also work with…
