Abstract (in Japanese) (See Japanese page) 
(in English) As demand for electric vehicles grows, the demand for EV supply equipment is also increasing.
In this study, we conducted an empirical study of two EV supply equipments products from domestic and international vendors and discovered four unknown vulnerabilities.
Next, we investigate the existing vulnerabilities released as CVEs, and identify that EV supply equipment vulnerabilities exhibit certain patterns.
We then found several insights.
First, vulnerabilities tend to arise in the Bluetooth, OCPP, and USB interfaces of EV supply equipments.
Second, RTOS-based EV supply equipments are prone to memory-related vulnerabilities, while Linux-based EV chargers tend to exhibit command injection vulnerabilities.
Third, vulnerabilities tend to arise in vendor-specific implementations such as OCPP.
