A control system, responsive to receiving values of one or more parameters of a battery of a vehicle for a particular time in service, generates via a machine learning determination a level of confidence at which the values of the one or more parameters of the battery match values of one or more parameters of a set of batteries for a same time in service, and responsive to the level exceeding a predefined threshold, causes a mitigation action to be implemented.

Methods and systems for recipient-assisted recharging during delivery by an unmanned aerial vehicle (UAV) are disclosed herein. During a UAV transport task, a UAV determines that the UAV has arrived at a delivery location specified by a first flight leg of the transport task. The UAV responsively initiates a notification process indicating that a recipient-assisted recharging process should be initiated at or near the delivery location. When the UAV determines that the recipient-assisted recharging process has recharged a battery of the UAV to a target level, and also determines that a non-returnable portion of the payload has been removed from the UAV while a returnable portion of the payload is coupled to or held by the UAV, the UAV initiates a second flight segment of the transport task.

When an adjustment target road in which a state of charge of the battery needs to be actively adjusted such as a congested road or a downhill road has been detected in the travel route based on the look-ahead information, the travel support control device performs state-of-charge adjustment control up to the adjustment target road. The travel support control device detects the adjustment target road based on look-ahead information generated for an estimated route on which it is estimated that the hybrid vehicle is to travel when the travel route has not been set, and performs the state-of-charge adjustment control up to the adjustment target road when the adjustment target road has been detected. At this time, a detection range for detecting a congested road and a detection range for detecting a downhill road in the estimated route are different.

Vehicles can employ onboard telematic monitoring devices to collect vehicle and operation data, such as for improved vehicle fleet management. Such telematic monitoring devices are dependent on power from a vehicle, such that data collection and communication can be interrupted if a telematic monitoring device is disconnected or has a poor connection. The present disclosure relates to battery devices, which provide power to telematic monitoring devices as needed in order to maintain data collection and communication, or other more limited functionality. The present disclosure also relates to systems including battery devices, and methods for operating battery devices. The present disclosure also relates to detecting temperature of batteries, as well as emergency input and messages for telematic monitoring systems.

A vehicle system is directed to providing a driver with a utility mode, which is an indoor environment condition of a vehicle where it may be rested, and includes: a vehicle communication portion that is configured to receive a first request message requesting execution of the utility mode by communicating with a service terminal provided in the vehicle or a driver terminal possessed by the driver; and a vehicle controller that is configured to set electric components and controllers involved in driving of the vehicle to an off mode when an entry condition for the execution of the utility mode is satisfied and the vehicle's starting is in an on-state, and sets an air conditioning device controlling an indoor air condition of the vehicle and a stack generating power required in the utility mode to a driving mode to execute the utility mode.

A method and a control device determine a position-related braking ability of a vehicle. A first vehicle determines at least one piece of position-related information of a route section, the at least one piece of position-related information of the route section being information relating to the braking ability on the route section. The first vehicle transmits the at least one piece of position-related information to a receiver, the receiver being at least one second vehicle, whereby the braking curves of at least one rail vehicle are adapted according to the situation, thus allowing safety on the route section and the utilization of the section to be improved.

The application provides a method, a charging-discharging device, a cloud server, a system and a medium for charging-discharging interaction, which belong to the fields of electric power technologies. The method for charging-discharging interaction includes: the charging-discharging device transmits a vehicle-to-grid V2G function confirmation message to a battery management system of a target vehicle; when no V2G function feedback message fed back by the battery management system is received within a preset period of time after transmitting the V2G function confirmation message, the charging-discharging device transmits a first indication message to a cloud server to indicate that the target vehicle is V2G-disabled; in response to a non-V2G charging instruction received from the cloud server, the charging-discharging device performs a non-V2G charging for the target vehicle. The availability of the charging-discharging device can be improved according to embodiments of the present application.

A method for matching data of a first control unit for controlling an electrical energy storage unit, which includes a plurality of electrochemical energy stores, with a second control unit for determining precise predictive values.

The disclosure provides a method and system for monitoring a battery short circuit and an apparatus. The method includes: receiving collected electrical signal information of all cells in each traction battery; performing self-discharge observation and calculating a self-discharge rate based on a cell voltage in electrical signal information of each cell after depolarization is completed, to determine whether there is an internal short circuit in a traction battery where the cell corresponding to the self-discharge rate is located; and triggering alarm handling for the internal short circuit in the traction battery based on a back-fed result that there is an internal short circuit in the traction battery. In this way, a problem of how to monitor a micro-internal short circuit in a traction battery in a good static working condition with accuracy and efficiency while taking operation into consideration is solved, data collection of a static battery and calculation based on big data records are implemented, and a calculation method is improved, thereby improving accuracy and efficiency of monitoring an internal short circuit in the traction battery while taking operation into account.

An electric vehicle (EV) is charged according to a selected charging rate. An available dispatch time is determined based on a current charge level of a battery of the EV, a first charging rate, and a target charge level. An anticipated dispatch time is determined based on predicted demand for a fleet of EVs that includes the EV. If the available dispatch time is later than the anticipated dispatch time, the first charging rate is selected; if the available dispatch time is earlier than the anticipated dispatch time, a second charging rate that is lower than the first charging rate is selected. The second charging rate may be a rate that charges the battery of the EV to at least the target charge level in time for the anticipated dispatch time.
