Abstract: A method for managing power supply during charging operation of BEVs. The method includes establishing a communication with each of the slave devices installed in the BEVs and receiving input data from the slave devices in real-time via a communication interface. The method further includes calculating a total power currently utilized by a plurality of TRUs based on the received input data and determining a probability whether the calculated total power exceeds a maximum allowed power provided by the primary grid network during the charging operation in case a new charging request is received from a new slave device. Thereafter, the method further includes regulating, based on the determined probability, a power allocation of a group of TRUs among the plurality of the TRUs such that the total calculated power remains below a saturation point of the maximum allowed power.

Abstract: A method for managing power consumption in a BEV includes obtaining real time vehicle data via an ECU of the BEV and receiving information regarding deliveries that are planned by a user for a specific day based on a user input or data acquisition from a remote database. The method further includes determining consumption of energy for completion of the deliveries on the specific day based on the obtained real time vehicle data and the received information and then calculating a distance that can be traveled by the BEV based on the determined consumption of energy. The method further includes determining a temperature difference between an internal temperature of a TRU of the BEV and an external temperature outside the TRU in real time, estimating an impact of the determined temperature difference on the determined consumption of energy, and thereafter displaying the results of the estimation on an HMI.
