A server includes a processor configured to: acquire a starting position where a user starts to use a moving object including a rechargeable secondary battery, and a destination of the user; estimate a power amount for the moving object to move from the starting position to the destination; determine whether or not power of the secondary battery is consumed at the destination; increase the power amount when the power of the secondary battery is consumed at the destination; and charge the moving object to the power amount.

A method for ascertaining a state of an electric drive of a transportation device, in particular a bicycle. The method includes: providing sensor data from sensors of the drive, the sensor data indicating parameters of the drive if an instantaneous operating range of the drive and/or of the transportation device corresponds to a predefined operating range; storing such sensor data, as measuring sensor signals, which originate from sensors predefined for the predefined operating range; and recognizing a defect of the drive if at least one of the measuring sensor signals deviates from a predefined standard sensor signal by a predefined degree; as well as outputting a warning about the presence of the defect to a user of the transportation device.

A method for performing an electrical charging process for a vehicle in a charging park, the vehicle having at least one charging interface, while the charging park has at least one electrical charging station with at least one charging interface, comprises situating the vehicle in an actual physical location on the grounds of the charging park, and checking to see whether the actual physical location does or does not fulfill a physical access requirement to the at least one charging interface of the at least one charging station, and in the event that the access requirement is not fulfilled the driver is asked to place the vehicle in a nominal physical location, and in the event that the physical access requirement is fulfilled the vehicle is moved automatically from the actual physical location to a selected charging station among the at least one charging station and automatically arranged in a charging position.

Methods, systems, and apparatuses for power management of a vehicle are described herein. The battery levels and location of the vehicle may be monitored to manage the features or modes available to use on the vehicle. A distance from the vehicle to a location may be determined. Based on the distance, a threshold power level for the vehicle to move to the location may be determined. A battery level for the vehicle may be determined. The battery level may be determine to not satisfy the threshold power level for the vehicle to move to the location. Based on the battery level not satisfying the threshold power level, an operational command may be executed at the vehicle.

It is desirable to facilitate maintenance of a battery of a vehicle. Ideally, any non-optimal action performed on the battery—for instance excessive charging—should be identified such that an appropriate recommendation for a battery maintenance operation can be provided. For instance, a user of the vehicle may be instructed to charge the battery less often. Thus, in an embodiment, a device such as an Electronic Control Unit (ECU), will monitor one or more operational properties of the battery. Thereafter, the monitored property is evaluated by the ECU to determine an effect that the monitored property has on the lifetime of the battery. Based on this evaluation, the ECU performs an action with aim to prolong the lifetime of the battery, such as instructing a user of the vehicle to perform a particular action.

A backup battery control module configured to supply electric power from a backup battery to a load when electric power supplied from a main battery to the load is cut off. The backup battery control module is configured to: measure an open circuit voltage of the backup battery in a state in which an ignition switch is off; derive, based on a measured open circuit voltage, an already charged rate of the backup battery; measure an internal resistance of the backup battery in a state in which the ignition switch is off; derive a deterioration degree of the backup battery based on a measured internal resistance; derive a target charging rate based on the deterioration degree; and charge the backup battery until the target charging rate is reached in a case in which it is determined that the already charged rate is smaller than the target charging rate.

A work vehicle is configured to perform an activity in a work area. The work vehicle includes a chassis, a plurality of ground engaging members coupled to the chassis for movement of the chassis in the work area, a generator configured to generate energy from performance of the activity of the work vehicle in the work area, an energy storage device connected to the generator to store energy generated by the generator and configured to be charged to an initial charge, and a controller configured to establish an initial charge setting corresponding to the initial charge of the energy storage device based on at least one anticipated activity input of the work vehicle.

Systems, methods, devices, and models for range estimation and analysis in battery powered vehicles are described. Energy consumption over vehicle trips is collected, to evaluate weighting factors for a weighted sum. The weighted sum is evaluated based on determined weighting factors and expected trip data, to determine an energy consumption of a trip or trips of a vehicle. Determined energy consumption for trips is used for evaluating suitability of the vehicle for performing the trips.

A battery management apparatus is a battery management apparatus configured to manage a plurality of battery packs that are mounted in a vehicle and connected in parallel, the battery management apparatus including: a storage section configured to store a first computer program used in the battery management apparatus and a second computer program used in each of the plurality of battery packs; a judgment section configured to judge whether or not there is a mismatch between version information of the second computer program stored in each of the plurality of battery packs and version information of each of the first computer program and the second computer program stored in the storage section; and a notification section configured to notify a host computer of the battery management apparatus of the mismatch of the version information when there is the mismatch.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.
