Abstract: A modular and field upgradable infrastructure device is provided for electric vehicle (EV) charging. The infrastructure device comprises a common communications and control module/a common meter/power module that can be connected to individual charging modules. It further comprises one or more AC, DC and wireless charging modules as internal or external pluggable devices. The common communications and control module is coupled to the AC, DC and wireless charging modules such that the infrastructure device communicates with an EV using power line communications via a protocol or several protocols.

Abstract: Systems and methods are provided for Electric Vehicle Supply Equipment (EVSE) system clock time synchronization based on a short-range wireless communication-based automated process. A system comprises a cellular mobile device having a short-range wireless communication capability to communicate with one or more EVSEs. The system further comprises a smart EVSE capable of gaining network connectivity, maintaining an EVSE system clock, and storing multiple days or months interval data logs and charging session data in order to provide reporting to a utility that allows retroactively calculating meter data and performing accurate billing to its customers such that the smart EVSE to synchronize time if power is lost when the network connectivity is down and to retrieve the interval data logs and the charging session data for updating to a cloud automatically to gain network connectivity for gaining an ability to perform Network Time Protocol (NTP) synchronization of the EVSE system clock.
