A vandalism detection and alert system (VDAS) is provided for an EV charging network monitored by a charge point operator (CPO). The VDAS is designed for use with a network whose EV charging stations use connector cables that include NTC cables to monitor over-temperature conditions. The VDAS includes an NTC monitoring logic module that continuously monitors each NTC cable in a given charging station. If there is a discontinuity in the communication path between an NTC cable and the NTC monitoring logic, the connector cable has likely been vandalized. The discontinuity causes an alarm to be issued in the specific charging station where the cable was vandalized and also causes an alert to be sent to the CPO. The CPO then issues a Panic Alarm command to all other charging stations associated with the site, causing all charging stations at the site to actuate their alarms.
