XING Mobility has announced the official release of its IMMERSIO Cell-to-Pack (CTP) product at the IAA Mobility show in Munich, Germany. This innovative battery pack, which features high energy density and exceptional heat dissipation and safety features, will be presented for the first time to the global audience at the event. XING’s IMMERSIO CTP Solution…

When designing a battery into an EV, you must perform rigorous testing to understand a battery’s performance. Electric vehicles (EVs) accounted for 13% of global vehicle sales in 2022 and are forecasted to reach 30% of global vehicle sales by 2030. The industry needs to continue working on making EVs affordable to support this transition…

In a video, EE World spoke with a power-supply applications engineer about why RV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, batteries deliver the power needed move the vehicle. Of course, EV batteries need…

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…

Magnachip Semiconductor Corporation announced that the Company has released four new MXT LV Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs)*, using Super-Short Channel technology, to further expand Magnachip’s seventh-generation MXT LV MOSFET line-up for battery protection circuits of mobile devices. Super-Short Channel is Magnachip’s latest design technology to reduce Ron (the resistance of MOSFETs during on-state operation) by shortening the…

Li-ion batteries can store large amounts of energy, and they can support high rates of power delivery. They are the preferred energy storage technology for EVs and large battery energy storage systems (BESS). But if not properly managed, they can also present safety hazards. That makes functional safety a critical consideration when designing large Li-ion…

Vehicle-to-grid (V2G) technology is often touted as one key to a more sustainable energy infrastructure. Like other areas where technology strongly impinges on economic and social interactions, however, the reality is complex and nuanced. Battery chargers can be a particularly daunting technical problem when implementing V2G. The charger must be bidirectional and offer high efficiency.…

Liquid metal batteries are being developed primarily for battery energy storage system (BESS) systems but may find future applications in electric vehicles (EVs) and wearables and portable devices. The first commercial BESS using a liquid metal battery is expected to become operational soon, but the longer-term outlook for large-scale market penetration remains cloudy. The first…

Diodes Incorporated announced a further enhancement of its wide-bandgap product offering with the release of the DMWSH120H90SM4Q and DMWSH120H28SM4Q automotive-compliant Silicon Carbide (SiC) MOSFETs. These N-channel MOSFETs respond to the increasing market demand for SiC solutions that enable better efficiency and higher power density in electric and hybrid-electric vehicle (EV/HEV) automotive subsystems like battery chargers,…

To provide BEV and HEV designers with a faster and more reliable high-voltage circuit protection solution, Microchip Technology announces the E-Fuse Demonstrator Board, enabled by silicon carbide (SiC) technology, available in six variants for 400–800V battery systems and with a current rating up to 30 amps. The E-Fuse demonstrator can detect and interrupt fault currents in microseconds,…
