Omron G9KJ relay handles 1500 V pre-charge in EV chargers and grid storage

Omron Electronic Components Europe has put the G9KJ relay into production, a compact PCB-mount device rated to 1500 VDC and aimed squarely at pre-charge circuits in battery energy storage systems and high-voltage EV fast chargers. It is a small component with a pointed job, and its arrival reflects how seriously the industry now takes a switching function that was, not long ago, treated as an afterthought.

Porsche debuts 11 kW wireless inductive charging for new Cayenne Electric

Porsche has developed a wireless charging system for its next generation battery-electric vehicles, designed to deliver AC charging performance of up to 11 kW without the need for a cable or wallbox. The system is based around a flat floor plate containing transmitter coils which, when connected to the grid, transfers energy inductively to a receiver unit integrated into the underbody of the vehicle.

Advanced thermal management in HV harness supports megawatt-scale fast charging

The management of thermal loads during high-current charging events remains a major technical challenge in e-mobility. While core drive system components such as inverters, electric motors, and high-voltage batteries are typically liquid-cooled, the high-voltage cables and charging harnesses connecting these systems have traditionally remained uncooled.
