Sponsored by Pickering. EV platforms live at the intersection of high voltage, high power and strict safety requirements. From battery packs and traction inverters to DC fast chargers and cable harnesses, engineers must prove that insulation is sound during development and at end-of-line. That is the role of high-potential testing. In a withstand test the… Read more »

Altech demonstrates safety of sodium-nickel-chloride batteries under destructive test conditions
Solid-state battery developer Altech Batteries has completed a full suite of safety self-destruction validation tests on its sodium-nickel-chloride (SNC) battery technology, which it recently began selling. The tests were designed to simulate the most severe field hazards that can occur during storage, transport or operation. Across all the scenarios, which included direct fire exposure, rod… Read more »
Cadillac Optiq: US luxury brand’s compact EV powerhouse
This largish “compact” crossover SUV is luxurious, quiet, and offers substantial range along with premium features, making it a truly competitive luxury EV—and shoppers are noticing. The conversion of GM’s luxury brand Cadillac to an all-electric product line has been a quietly seismic event over the last decade. The brand is finding (it says) newer,… Read more »
Archer to acquire storied Los Angeles airport, repurposing it as an electric air taxi hub
Archer Aviation has agreed to acquire the master ground lease for Hawthorne Airport in Los Angeles, California and repurpose it as a strategic air taxi network hub. Hawthorne Airport, also known as Jack Northrop Field, is currently a public-use airport. The name comes from the founder of Northrop Aircraft, Jack Northrop, who founded the company… Read more »
A closer look at capacitor precharge and inrush current control
The vast majority of power converters used in the EV space—from battery chargers to traction inverters—are classified as voltage-fed, meaning they expect to be supplied from a source whose voltage varies little with changes in current draw (i.e. has a low impedance), and the best way to ensure this condition is with a capacitor across… Read more »
Wolfspeed unveils new 1200 V silicon carbide power modules for high-efficiency EV inverters
Wolfspeed has announced the release of its 1200-volt silicon carbide (SiC) six-pack power modules, targeting high-power inverter applications for electric vehicles and industrial machinery. The new modules utilize Wolfspeed’s Gen 4 SiC MOSFET technology combined with updated packaging to deliver what it claims is three times the power cycling capability at operating temperature compared to… Read more »
Microchip unveils 10BASE-T1S endpoint devices to streamline zonal automotive Ethernet connectivity
Microchip Technology has announced the LAN866x family of 10BASE-T1S endpoint devices with Remote Control Protocol (RCP), aiming to simplify in-vehicle Ethernet network integration in zonal architectures. The company says these endpoints allow direct translation of Ethernet packets to local digital interfaces, removing the need for custom software or microcontrollers on each network node. The LAN866x… Read more »
Henkel launches two new thermal potting solutions for EV powertrain components
Component integration is a key strategy in the EV industry. Increasingly, multiple powertrain components, such as the motor, inverter, on-board charger and DC-DC converter, are combined into a single compact unit. This approach delivers significant benefits in efficiency, weight reduction and space optimization. However, it also presents new engineering challenges, particularly in managing heat dissipation… Read more »
