This startup is cutting the cord on EV battery wiring to make them safer and smarter.

Dukosi, a company based in Edinburgh, has started sampling a new contactless communication system for lithium-ion battery packs used in electric vehicles and grid storage. Their DK-NFLNK system replaces traditional copper wiring harnesses with wireless near-field radio signals to transmit critical data like voltage and temperature from individual cells to a central monitoring unit via a single antenna.

The goal is to eliminate a key failure point—physical connectors, which have a failure rate of about 10 parts per million—and enable more reliable, real-time thermal monitoring. This wireless architecture supports the creation of detailed 'battery passports' required by upcoming EU regulations. The takeaway is a clever hardware innovation tackling a fundamental challenge in high-density energy storage: making the nervous system of a battery pack more robust and less prone to physical wear and tear.
