Sulfur cathode technology enters EV battery evaluation
A top-15 global automaker will evaluate Gelion’s nano-encapsulated sulfur cathode technology across several electric vehicle (EV) battery cell configurations. Under a material transfer agreement, Gelion will provide its NES sulfur-based cathode active material, coated cathodes, and liquid electrolyte for testing by the unnamed automotive OEM. The automaker will evaluate the cathode in both liquid- and…
Multilayer inductors for automotive power-over-coax circuits
TDK has expanded its MLJ1608-G series of multilayer inductors for automotive power-over-coax (PoC) circuits. Automotive PoC technology allows power and data to be transmitted simultaneously over a single coaxial cable. It is primarily used with automotive cameras for advanced driver-assistance systems (ADAS), including those used in electric vehicle (EV) platforms. Using a single cable instead…
Modular EV charge controller combines hardware and open-source charging software
Pionix, AST-X, and Solectrix have partnered on a customizable charge controller for electric vehicle (EV) charging systems. The platform combines a pre-validated controller design with the open-source EVerest charging software stack. The controller is based on Pionix’s ChargeBridge reference design and can be adapted to different charger designs and interface requirements. Manufacturers can begin development…
New microdispensing system for EV battery and e-motor production
Dürr has introduced the EcoMeter XS, a compact microdispensing system designed to apply small quantities of adhesives, sealants, and other high-viscosity materials. The system can be used in electric vehicle (EV) manufacturing processes involving battery systems, power electronics, and electric motors. One EV battery application involves dispensing thermal-interface material onto cylindrical cells. Approximately 0.1 cm³…
How do two-level and three-level inverter topologies compare in EVs?
Whenever an electric vehicle (EV) battery bus exceeds 400 V, it poses powertrain design challenges for engineers. One of the key design challenges is the choice of inverter topology, whether a two-level or a three-level inverter topology. Though a three-level inverter has a higher device count, we will discuss in the article where these topologies…
