Pickering Interfaces announced the latest version in its 41/43-752A range of battery simulator modules. Ideal for EV battery stack emulation in BMS test applications, the 41/43-752A-111’s increased voltage isolation (now 1000V) will be essential as the EV industry shifts from 400V to 800V architectures. Targeting EV (electric vehicle), electric aircraft and other automotive, aerospace and energy…

Halo Microelectronics announced the release of its HL7040C, a highly integrated family of 2x2mm single-cell Li-Ion and Li-Pol linear chargers. The HL7040C is ideal for portable applications, including smartphones, PDAs, MP3 players, and low-powered handheld devices with limited board space, as it operates from either a USB port or an AC adapter. The high-input voltage […]

Rare earths play an important part in the sustainability of electric vehicles (EVs). While there are sustainability challenges related to EV batteries, rare earths are not used in lithium-ion batteries. They are necessary for the magnets that form the main propulsion motors. The batteries mostly rely on lithium and cobalt (not rare earths). At the…

Several things. First, quick charge is used with devices like smart phones and tablet computers, while extreme fast charging (XFC) is used with electric vehicles (EVs). Quick charge (QC) is generally slower than extreme fast charge. QC has competitors like universal serial bus power delivery (USB-PD), IEC 62680-1-2:2022, and USB extended power range (EPR). Tesla…

While lithium-ion battery chemistry dominates the current electric vehicle market, scientists are working to develop innovative battery chemistries that address the known challenges the existing chemistry presents. By Adam Kimmel for Mouser Electronics Sales of electric vehicles (EVs) continue to outpace the overall automotive segment, with EV market shares of 5.2% in Q1 and 5.6%…

A research team comprised of Princeton, Vanderbilt, and Argonne and Oak Ridge National Labs researchers claims to have uncovered a hidden flaw behind failures in solid-state batteries. In a solid-state battery, ions move through the battery within a solid material, in contrast to traditional lithium-ion batteries, in which ions move in a liquid. Solid-state cells…

There are many alternatives to Li-ion batteries, including fuel cells, various types of supercapacitors, redox flow batteries, novel Li-based chemistries such as lithium-sulfur (LiS), and more. This FAQ focuses on alternative non-lithium rechargeable battery chemistries, including calcium-ion (Ca-ion), magnesium-ion (Mg-ion), sodium-ion (Na-ion), zinc-ion (Zn-ion), iron-air (Fe-air), and sodium-sulfur (NaS) that can be more readily integrated…
