A computer can execute instructions to: receive, power-receiving vehicle data identifying a power-receiving vehicle; identify one or more power-supplying vehicles for providing charging to the power-receiving vehicle; determine a rank for each of the identified one or more power-supplying vehicles based on the received power-receiving vehicle data and data received from the one or more power-supplying vehicles; upon selecting one of the one or more power-supplying vehicles, provide a navigation instruction to navigate at least one of the power-receiving vehicle and the selected power-supplying vehicle to a charging location based on a power-receiving vehicle location and a selected power-supplying vehicle location; and send access data to the power-receiving vehicle to access a charge port of the selected power-supplying vehicle; send a first light actuation instruction to the power-supplying vehicle based on a charging status; and send a second light actuation instruction to the power-receiving vehicle based on charging status.

A vehicle includes: an on-board inverter that adjusts the voltage of an electric power; and a vehicle inlet. The vehicle inlet has a CS terminal through which a proximity detection signal for identifying the connection state between a discharge connector and the vehicle inlet is transmitted. An electronic control unit (ECU) includes a processor that selects the voltage of an electric power output from the on-board inverter. When the proximity detection signal is in a first bound (a fourth range or a fifth range), the processor selects AC 100V, and when the proximity detection signal is in a second bound (a fifth range or a sixth range) at least partially different from the first bound, the processor selects AC 200V higher than AC 100V.

A charging management apparatus includes a main relay connected between a positive electrode terminal of a battery pack and a charging terminal of a charging connector, a current regulator connected in parallel to the main relay and including a precharge relay and a resistance regulation circuit connected in series, a battery pack voltage sensor, a battery pack current sensor, and a controller to control the main relay is into an on state and the precharge relay into an off state in response to a first switching condition while the main relay is in the off state, the resistance regulation circuit at a first resistance value and the precharge relay is in the on state, and to control the resistance regulation circuit to a second resistance value, the precharge relay into the on state and the main relay into the off state, in response to a second switching condition.

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 method for carrying out a process for charging an appliance battery of an appliance, with the following steps: providing a charging profile that specifies a maximally permissible charging current for charging the appliance battery in a manner depending on a state of charge of the appliance battery; ascertaining a current state of health of the appliance battery; providing a reference state of health that predetermines a customary state of health for a calendrical age of the appliance battery; charging the appliance battery in a manner depending on a corrected maximally permissible charging current, the corrected maximally permissible charging current being ascertained by applying a correction value to the maximally permissible charging current, the correction value being determined in a manner depending on a correction function, depending on a difference between the reference state of health and the current state of health.
