NASA-Certified M35A Battery Cells

KULR Technology Group, Inc. (San Diego, CA) has announced the immediate availability of NASA-certified M35A battery cells, qualified for use in JSC 20793-compliant battery packs. These 18650 cells are ready for procurement and represent a critical advancement in KULR’s mission to provide rapid access to certified space-ready solutions. The M35A cells have undergone rigorous validation, meeting NASA’s stringent requirements through both initial lot assessment and lot acceptance processes conducted under formal NASA Work Instructions. The M35A is a strategic component of NASA’s Artemis II mission, recognized for its exceptional cold-weather performance with an energy density of 214 Wh/kg at C/20 and -20 °C. KULR is also integrating the M35A into its proprietary 400 Wh K1 Space battery, a cutting-edge solution designed to meet the demands of human space exploration. In collaboration with NASA, KULR is working toward expanding the Strategic Battery Reserve to include larger-format cells and a broader range of qualified technologies. This initiative will enable faster procurement options and wider accessibility to 20793-compliant solutions for aerospace and defense applications.

Silicon Carbide Diodes

Nexperia (Nijmegen, Netherlands) has announced that its 650 V, 10 A silicon carbide (SiC) Schottky diode is now automotive qualified (PSC1065H-Q) and available in real-two-pin (R2P) DPAK (TO-252-2) packaging, making it suitable for various applications in electric vehicles and other automobiles. Additionally, in a further extension to its portfolio of SiC diodes, Nexperia is now also offering industrial-grade devices with current ratings of 6 A, 16 A, and 20 A in TO-220-2, TO-247-2, and D2PAK-2 packaging to facilitate greater design flexibility. These diodes address the challenges of demanding high voltage and high current applications including switched-mode power supplies, AC-DC and DC-DC converters, battery-charging infrastructure, motor drives, uninterruptible power supplies and photovoltaic inverters for sustainable energy production. The merged PiN Schottky (MPS) structure of these devices provides additional advantages over similar competing SiC diodes, including outstanding robustness against surge currents. This eliminates the need for additional protection circuitry, thereby significantly reducing system complexity and enabling hardware designers to achieve higher efficiency with smaller form factors in rugged high-power applications.

On-Board Charger

A critical application for EVs is the on-board charger, which converts AC power into DC power to recharge the vehicle’s high-voltage battery. Microchip Technology (Chandler, AZ) announced an On-Board Charger (OBC) solution that uses a selection of its automotive-qualified digital, analog, connectivity and power devices, including the dsPIC33C Digital Signal Controller (DSC), the MCP14C1 isolated SiC gate driver and mSiC™ MOSFETs in an industry-standard D2PAK-7L XL package. This solution is designed to increase an OBC system’s efficiency and reliability by leveraging the dsPIC33 DSC’s advanced control functions, the MCP14C1 gate driver’s high-voltage reinforced isolation with robust noise immunity and the mSiC MOSFETs’ reduced switching losses and improved thermal management capabilities. The dsPIC33C DSC is AEC-Q100 qualified and features a high-performance DSP core, high-resolution Pulse-Width Modulation (PWM) modules and high-speed Analog-to-Digital Converters (ADCs), making it optimal for power conversion applications. It is functional safety ready and supports the AUTOSAR® ecosystem.

Electric Motor Wave Spring

Rotor Clip (Somerset, NJ) has announced its new, patented InterShim™ Wave Spring design. Engineered for high-acceleration electric motor applications, this innovative design features alternating turns between inactive (flat) and active (waved) turns to ensure reliable performance under torsional loads and precise rotational movement. The introduction of the InterShim™ Wave Spring reflects Rotor Clip’s commitment to advancing product technology and meeting market needs. The benefits of the InterShim™ Wave Spring include: Meeting the demands of applications requiring high torsional loads and precise rotational control; increased efficiency by eliminating the need for multiple elements within the assembly line; floating ends and bent ends can help prevent damage to the mating surface; allows for higher preload or softer spring rates to meet specific customer requirements; and highly customizable in the number of waves, number of turns, arrangement of shims/troughs, and a variety of specialty alloys.
