A device for providing charging information for a charging process is configured to determine a total set of N data tuples for N different times of a charging time period for the charging process. A data tuple includes values of one or more characteristic variables relating to electrical energy that can be provided in the charging process. Furthermore, the device is configured to reduce the total set of N data tuples to a reduced set of M data tuples, with M<N, and to provide the reduced set of M data tuples for the determination of a charging plan for the charging process.

A battery rotation system for rechargeable batteries. The system includes a plurality of battery monitors each configured to mount to a rechargeable battery, each connected to the terminals of the battery, and each including a current sensor, a voltage sensor, and a temperature sensor. The system further includes a server in wireless communication with the battery monitors to receive battery status information from the monitors. When a battery is connect to a battery charger, the battery monitor determines when the battery is ready for use. The server maintains queue information of available batteries and sends that information to a remote user device. The server also can schedule battery replacements and schedule charging times based on peak hours.

An information calculation system acquires a battery load history of a secondary battery that has been used. The information calculation system calculates first degradation states of a plurality of battery constituent elements of the secondary battery, based on the battery load history acquired and a plurality of degradation factors related to each of the battery constituent elements. The information calculation system acquires estimated load information on a load that is estimated to act on the secondary battery when the secondary battery is used in a future application. The information calculation system calculates future second degradation states of the plurality of battery constituent elements of the secondary battery when the secondary battery is used in the future application, based on the first degradation states related to the battery constituent elements calculated, the estimated load information acquired, and the plurality of degradation factors related to the battery constituent elements.

Techniques are described herein for fleet electrification management. A method includes determining a composition of electric vehicles (EVs) to replace at least a portion of non-electric vehicles in a vehicle fleet while satisfying travel requirements of the vehicle fleet. The method includes estimating an energy demand of the composition of EVs. The method includes determining an electric vehicle supply equipment (EVSE) charging infrastructure to meet the estimated energy demand. The method includes providing one or more recommendations including at least one of: a fleet electrification recommendation for transitioning the vehicle fleet into the composition of EVs, or a charging infrastructure recommendation for implementing the EVSE charging infrastructure.
