A management device is a management device that: manages batteries; receives a first battery; and supplies a second battery. The management device includes an obtaining portion that obtains, from the first battery, first identification information stored in the first battery. The management device includes an authenticating portion that authenticates a user of the first battery by using the first identification information the obtaining portion has obtained. The management device includes a writing portion that, if the authenticating portion authenticates the user, writes the first identification information to the second battery that is to be supplied to the user.

A battery pack lift system includes: a frame having nutrunners mounted thereon according to a battery pack fastener pattern for a vehicle; a lift configured to raise and lower the frame with regard to the vehicle; a first air bearing positioned between the frame and the lift, the first air bearing configured to allow relative movement between the frame and the lift; and a second air bearing positioned on the frame, the second air bearing configured to allow relative movement between a battery pack and the frame.

In an embodiment, an expansion component (e.g., expanding foam element, inflatable pad, a pneumatic or hydraulic mechanism, etc.) is arranged inside of a battery module compartment (e.g., on a bottom interior surface of the battery module compartment). A battery module is inserted into the battery module component and is fixated, or secured, within the battery module compartment at least in part based upon the expanding component which starts to expand or continues to expand after the insertion. In a further embodiment, the battery module may be removed from the battery module compartment after a contraction function (e.g., collapse of the foam element, deflation of the inflatable pad, etc.) of the expansion component is initiated.

Embodiments of the present application provide a vehicle control method, module, and system, a device and a medium. The method includes: acquiring, under a condition that it is determined to install a target battery provided by a battery swapping station for the vehicle, a network address of a first battery management unit of the target battery; requesting to establish a wireless communication connection between a control module and the first battery management unit, based on the network address of the first battery management unit of the target battery; transmitting, under a condition that the wireless communication connection between the control module and the first battery management unit is successfully established, a first prompt signal to a target object, where the first prompt signal is used to prompt the target object to perform a relevant operation for allowing the vehicle to leave a battery swapping area.

A battery system for an electric vehicle is provided. The electric vehicle includes a motor and a vehicle control unit. The battery system includes a first battery module, a second battery module configured to accommodate a plurality of swappable batteries, and a power control module configured to receive a driving intention from the vehicle control unit and switch a power supplying configuration of the motor according to the driving intention. The power supplying configuration includes a power supply by the first battery module only, a power supply by the second battery module only, a power supply by the first battery module and the second battery module in series, and a power supply by the first battery module and the second battery module in parallel.
