    Abstract: An electrical system is usable with an offboard charging station and configured to dynamically adjust a power limit of the electrical system during a battery charging process. The system includes a battery pack, charge coupler, power electronic components, temperature sensor(s), and a controller. The components include a most-limiting component, and are electrically connected to the battery pack with corresponding temperature-based operating performance information. The information describes a maximum allowed charging current over different time intervals. The most-limiting component has a lowest allowed charging current. The controller executes a method by determining a component temperature using the measured temperature(s), and requests increased charging current from the power supply over one or more of the time intervals to supply the battery pack with the maximum allowed charging current of the most-limiting component. A vehicle includes the system and an electric machine delivering torque sufficient for propelling the vehicle.

    Abstract: A computer processor is embedded in a vehicle and a display device embedded in the vehicle is communicatively coupled to the computer processor. The computer executes logic to receive a price per unit of energy that is stored in the vehicle, compute an energy consumption rate of the vehicle over a time period, multiply the price per unit by the energy consumption rate to determine a cost of the energy consumption rate over the time period, and display the cost of the energy consumption rate for the time period on the display device in the vehicle.

    Abstract: A method for predicting the duration of a future charging process for a vehicle battery. The method comprises estimating a future charge amount of the battery corresponding to the start of the future charging process. The method further comprises estimating a future temperature of the battery. The method still further comprises determining a future charging power or a characteristic thereof to be applied to the battery during the future charging process, wherein the future charging power or characteristic thereof is based on the estimated future charge amount and the estimated future temperature and is representative of a charging amount or characteristic thereof that will maintain the temperature of the battery at or below a threshold temperature during the future charging process. The method still further comprises predicting a duration of the future charging process based on the estimated future charge amount and the determined future charging power or characteristic thereof.
