ChargeX: Exploring State and Rate Attacks in Electric Vehicle Charging Systems
- Published
- Record updated
Summary
Researchers examined the communication between EV chargers and vehicles and found the SAE J1772 charging control protocol lacks authenticity protection. They proposed ChargeX, a class of attacks that inserts a hardware circuit to modify charging control signals, and tested it on a public charging station and two home chargers using a simulated vehicle load. They showed it could force a Tesla's charging state from "stand by" to "charging", potentially causing overcharging, and could push any state into an error state for a denial of service.
