Abstract: A system comprises an Electric Vehicle (EV) charger with an electronic display screen having an e-ink/e-paper display—a technology that allows displaying information without power and an Open Charge Point Protocol (OCPP) backend system that receives charging data and sends charging commands based on dynamic load management principles via communication between chargers and central back-end EV charging management systems. The system further comprises a first dynamic Quick-Response code (QR code) representing the EV charger for the purposes of charger commissioning and configuration is presented on the e-ink/e-paper display during a boot time, and during (re-)configuration time whenever the EV charger is placed in a (re-)configuration mode and a second dynamic QR code different from the first dynamic QR code related to the OCPP backend system to which the EV charger is connected is presented on the e-ink/e-paper display during an operational time.

Abstract: Methods for performing certificate-based authentication for a charging session of an electric vehicle are provided. Aspects include broadcasting, by a charging station, a charging station availability message, establishing a connection between a user device and the charging station via a wireless personal area network protocol, and receiving, by the charging station from the user device via the connection, a user certificate stored on the user device. Aspects also include validating, by the charging station based at least in part on a public key of the user certificate, the user certificate and enabling the charging session based on a determination by the charging station that the user certificate is valid. Aspects further include recording, by the charging station, charging session data and transmitting the charging session data to the user device based on a determination that an internet connection of the charging station is not available.

Abstract: A system for a firmware update includes an industrial device, such as an electric vehicle charging device, with firmware, a central server with an interface configured to collect and process data from a data source, a network, wherein the industrial device and the central server are configured to communicate via the network, and a cost-benefit-analysis (CBA) module for performing a cost-benefit analysis, wherein the CBA module is configured via executable instructions to calculate relative costs for a firmware update of the industrial device utilizing the data from the data source, determine a relative benefit for the firmware update of the industrial device, and compare the relative costs to the relative benefit.
