Abstract:
A networked charging station for electric vehicles protects against overcurrent and ground fault conditions. Upon detecting an overcurrent condition or a ground fault condition, the networked charging station for electric vehicles de-energizes a charging point connection to prevent electric current from flowing between an electric vehicle and the networked charging station and suspends the charging session. The networked charging station clears the overcurrent condition or the ground fault condition upon receipt of an authorized request which is transmitted remotely. The authorized request can be received from the vehicle operator that is associated with the charging session or from an administrator of the charging station through a radio-frequency identifier (RFID) tag enabled device or through a text message or an email message. The networked charging station clears the overcurrent condition or the ground fault condition without a manual reset of a circuit breaker or a GFCI device respectively.
