Various disclosed embodiments include illustrative controller units, systems, vehicles, and methods. In an illustrative embodiment, a controller unit includes a communication component, a controller and a memory. The communication component is configured to communicate with a direct current charging device. The controller is configured to communicate with the communication component and the memory. The memory is configured to store computer-executable instructions configured to cause the controller to determine a target location, receive location information of a vehicle, receive state of charge information, determine a charging request in response to the target location, the location information of the vehicle, and the state of charge information, and send, via the communication component, the determined charging request to the direct current charging device connectable to the vehicle.

A charging amount calculation apparatus calculates an amount of power consumption by a battery for running along a running route and a during-running charging amount received by a power reception apparatus from at least one second power feeding facility. The charging amount calculation apparatus calculates a pre-running charging amount based on the amount of power consumption and the during-running charging amount.

A method for acquiring information of a battery cell (11) includes a step (S101) of acquiring information pertaining to performance recovery accompanying the suspension of charging/discharging of the battery cell (11). Control pertaining to the battery cell (11) and estimation of a state of the battery cell (11) can be appropriately performed according to a type of battery cell (11).

An example operation includes one or more of determining a first transport attempting to access a bay with a charging station can utilize the charging station and has a higher priority than a second transport utilizing the charging station in the bay and notifying the second transport to cease utilizing the charging station and to vacate the bay after a time.

A method of detecting a thermal event associated with a battery assembly of an electrified vehicle includes, among other things, obtaining a temperature reading from a sensor associated with an area of the battery assembly, assessing whether the sensor is flagged with a first identifier or a second identifier. The first identifier indicates that the temperature reading is reliable. The second identifier indicates that the temperature reading is unreliable. If the sensor is flagged with the first identifier, the method detects a thermal event associated with the battery assembly based on the temperature reading from the sensor.

Techniques are presented for scheduling the charging of electric vehicles (EVs) that protect the resources of local low voltage distribution networks. From utilities, data on local low voltage distribution networks, such as the rating of a distribution transformer through which a group of EVs are supplied, is provided to a load manager application. Telematics information on vehicle usage is provided from the EVs, such as by way of the original equipment manufacturer. From these data, the load manager application determines schedules for charging the group of EVs through a shared low voltage distribution network so that the capabilities of the local low voltage distribution network are not exceeded while meeting the needs of the EV user. Charging schedules are then transmitted to the on-board control systems of the EVs for implementation.

A charging management unit of a charging management server acquires contact information of a first user who uses a charging unit for charging a traction battery of a vehicle. The charging management unit of the charging management server receives a first request indicating that a second user, who is a user different from the first user, wants to use the charging unit being used by the first user after the first user has finished using the charging unit. When the charging management unit of the charging management server receives the first request, it notifies the first user about the first request.

A vehicle battery diagnosis method and system are provided. A controller completes charging a battery by stopping supply of current from a charger to the battery. The controller measures a relaxation voltage corresponding to a decrement of a voltage of the battery during a predetermined time period directly after the charging of the battery is completed. The controller estimates the state of health (SoH) of the battery in accordance with the relaxation voltage.

The present disclosure relates to systems, devices, and methods for analyzing health of vehicle batteries. Vehicle batteries tend to degrade over time. The described systems, devices, and methods quantify this degradation (or quantify remaining health of the battery) by comparing average energy used to charge or discharge the battery by a charge level unit to a nominal quantity of energy used to charge or discharge a battery in optimal health by a charge level unit. Charge data for previous charge events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified charge events based on at least one of a number of metrics. Usage data for previous usage events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified usage events or subgroups of usage event based on at least one of a number of metrics.

A method and a device for controlling vehicle charging, a program, a medium, and a vehicle is provided. The method by acquiring a current connection state of a telematics box in the vehicle and the server when a charging gun of a vehicle is determined in a connection state; and recording a first duration of the offline state when the current connection state is determined in an offline state, and controlling the vehicle charging according to the first duration. In this way, when it is determined that the current connection state is in the offline state, the vehicle charging can be controlled according to the duration of the offline state, which can effectively avoid the problem of charging failure due to network connection failure during the reservation charging process, the reliability of vehicle reservation charging is improved, and thus the vehicle user experience is effectively improved.
