The control apparatus is configured to control power supply in response to reception of a power supply request. The one or more processors perform setting a charge start time, starting the power supply to the power system if the power supply request is received before the charge start time, controlling the power of the power supply so that State of Charge in the in-vehicle battery becomes lower than or equal to a predetermined value before the charge start time, and controlling the power of the power supply so as to be lower than or equal to a predetermined upper limit at which increase in deterioration in the in-vehicle battery due to the power supply can be suppressed.

The present application provides a method for managing charging in a battery swapping station. The method includes: receiving, by the first management unit, a wireless communication connection instruction transmitted by a management device of the battery swapping station, wherein the connection instruction includes a network location address of a second management unit of a battery pack; initiating, by the first management unit, a wireless communication connection to the second management unit based on the network location address; uploading, by the first management unit, battery status information of the battery pack acquired from the second management unit to the management device; and under a condition that the first management unit receives a charging instruction transmitted by the management device based on the battery status information, controlling, by the first management unit via an interaction with the second management unit and the charging unit, the charging unit to charge the battery pack.

The present invention relates to a control system (10) for an electric machine (EM), for producing a braking torque, by means of the electric machine (EM), in a traction drive, said system comprising a control device (SE), the control device (SE) being configured to control a generator voltage or a generator current in or through a power electronics system (LE) of the electric machine such that during a movement of the traction drive, the electric power (Pel) of the electric machine (EM) can be limited to a level at least below a predefined minimum value.

A charge control device is mounted on a vehicle to which external power for charging a storage battery is supplied from an external power supply. The charge control device has an acquisition part, a calculation part, and an output part. The acquisition part acquires a detection result of a physical quantity sensor that detects a physical quantity related to charging of the storage battery. The calculation part changes a target value of the physical quantity when a charge amount of the storage battery is equal to or greater than a target charge quantity and a difference between the target value of the physical quantity and the detection result is lower than a predetermined value. The output part outputs an instruction signal including an instruction to control an external power based on a target value to the external power supply.

The present disclosure relates to systems, methods, and devices for controlling charging of vehicles, to avoid charging during charge-adverse time periods or during charge restriction events. This can advantageously reduce cost to vehicles owners, and or provide access to reward incentives. Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.
