Critical Connections For EV Charging: Correctly Specifying Liquid Cooling Fluid Connectors

With fast- and extreme-fast EV charging, system manufacturers are quickly learning how and where to implement liquid cooling to keep powerful electronics components from overheating, failing, or causing damage. What is not broadly understood is which structural or performance characteristics of quick disconnect (QD) couplings need to be taken into account when spec’ing them into… Read more »

How pressure-sensitive adhesives enable advanced thermal runaway barrier design (Webinar)

Fires caused by thermal runaway continue to be a significant issue in the evolution of EV battery packs. Now, as the EV marketplace approaches a tipping point, engineers are racing to address this challenge using various technologies. These include high-performance, pressure-sensitive adhesives (PSA) used in combination with thermal materials that can assist in hindering thermal… Read more »

Storedot says its silicon-dominant battery cells can last for 1,200 cycles

Israeli battery tech developer StoreDot says its silicon-dominant cells have achieved a lifetime of 1,200 cycles in testing. Using a specially designed testing form factor, StoreDot’s engineers have exceeded 1,200 cycles with cells that are charged to 80% of capacity in 15 minutes, then discharged for one hour. The company says the results were achieved… Read more »

2022 Lucid Air: The makers of the first 500-mile EV should be taken seriously

Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »

A closer look at minimizing charging losses: The charger (Part 2)

In the previous article, we looked at the various losses incurred on the AC side of the circuit while charging an EV’s battery (from the breaker in the load center to the EVSE inlet on the EV), as well as things that could be done to minimize them, either by the OEM, the electrical contractor… Read more »

Power Integrations offers two new ICs with 1,700 V SiC MOSFET
