Abstract: A system and method for managing access to data of digital twin in industrial system includes one or more datasets of the digital twin being received from each of a plurality of devices of a hierarchical system. A state of the digital twin is determined by mapping each of the one or more datasets with pre-defined state data. Information related to a role of each of one or more users associated with each of a plurality of devices is received, and an matrix indicating the one or more users' access rights on one or more datasets is generated by mapping a state of the digital twin corresponding to each of the one or more datasets with the users' role in each. Access to one or more datasets by one or more users at each of the plurality of devices is managed based on the access matrix.

Abstract: In one aspect, a cross-connect cable for charging an electric vehicle (EV) is provided. The cross-connect cable comprises wiring, first and second charging plugs, a sensor, and a controller. The wiring comprises power conductors and communication lines. The first and second charging plugs are electrically coupled to opposite ends of the wiring. The sensor is configured to measure a voltage of, and a current carried by, the power conductors. The controller is configured to determine whether the first and second charging plugs have been electrically connected to first charging port of a power source and a second charging port of the EV, respectively. The controller is further configured to initiate a charging session from the power source to the EV, and calculate, based the voltage and the current, energy delivered from the power source to the EV for the charging session.

Abstract: The present invention relates to a method and a system for charging Electric Vehicles (EV) (101) at charging points associated with a first or a second energy distribution vendor (104). A charging point (103) connected to an electric vehicle system operator (EVSO) (105) receives information related to the EV (101) and an energy transaction for charging the EV (101). The EVSO (105) verifies the identity of the EV and charging point (101) and authorizes the charging point (103) to charge the EV (101) based on the energy transaction. The EVSO (105) determines the one or more sister block chain (401, 402 and 403) associated with the first or the second distribution vendor for storing the energy transaction. The EVSO (105) stores all the energy transactions associated with plurality of energy distribution vendors (104) in a mother block chain (404). Upon receiving the authorization, the charging point (103) charges, the EV (101).
