A group of teachers from the University of Oxford and Armasuisse S+T has disclosed details of a new attack system towards the well-liked Combined Charging System (CCS) that could probably disrupt the ability to charge electric automobiles at scale.
Dubbed “Brokenwire,” the technique interferes with the control communications that transpire in between the car or truck and charger to wirelessly abort the charging classes from a distance of as significantly as 47m (151ft).
“When it may perhaps only be an inconvenience for people today, interrupting the charging process of critical vehicles, this sort of as electric powered ambulances, can have life-threatening implications,” the researchers discussed.

“Brokenwire has fast implications for a lot of of the 12 million battery EVs estimated to be on the roadways around the world — and profound effects on the new wave of electrification for automobile fleets, both of those for non-public organization and for critical community services.”
Further information of the attack’s modus operandi have been stored below wraps so as to avert active exploitation in the wild although involved stakeholders work in the direction of arriving at appropriate countermeasures.
Mixed Charging Method refers to a form of connector used for swift-charging electric vehicles. Brokenwire will take aim at this technology by transmitting a destructive electromagnetic signal, triggering the charging system to be unexpectedly stopped.
The researchers pointed out that the attack can be mounted with an assorted mix of off-the-shelf radio parts these types of as software program-outlined radio, ability amplifiers, and a dipole antenna, not to point out be executed in particular person from a close by area or by deploying a machine at a focus on site and manage it remotely.
“The use of PLC [power-line communications] for charging communication is a critical structure flaw that leaves hundreds of thousands of cars, some of which belong to critical infrastructure, vulnerable,” the scientists said.
