Disclosed are a battery swapping station and a control method therefor. The battery swapping station comprises: a first battery swapping platform being arranged between a first charging compartment and a second charging compartment; a first shuttle travels between the first battery charging compartment and the first battery swapping platform, a second shuttle travels between the second battery charging compartment and the first battery swapping platform; a control unit being electrically connected to the first shuttle and to the second shuttle, used for the following operation: when operating a same vehicle on the first battery swapping platform, if the first shuttle is executing either operation of battery unmounting or battery mounting, the second shuttle executes the other operation. Through the battery swapping station and the control method therefor, the waiting time for vehicles when swapping batteries can be reduced, thus increasing the battery swapping efficiency of the battery swapping station.

An electric vehicle (1) has a battery (2) in an underfloor arrangement. The battery (2) is arranged in a battery space (4) that is delimited by body members (5, 6, 7, 8) of a body (3). The battery space (4) also is delimited at a bottom side of the electric vehicle (1) by way of a protective plate (9). The battery (2) has a connection element (10, 11) at least on a side oriented toward one of the body members (7, 8), and the body member (7, 8) has a recess (12, 13) in which the connection element (10, 11) is arranged.

A vehicle lower structure includes: a battery pack provided under a floor of a vehicle cabin; a framework member fixed to a bottom surface of the case, the framework member extending across the case in a vehicle width direction; a first extension framework member detachably attached to one end of the framework member in the vehicle width direction such that at least one of distal ends of the first extension framework member in the vehicle width direction is located outward of one end of the case in the vehicle width direction; and a second extension framework member detachably attached to the other end of the framework member in the vehicle width direction such that at least one of distal ends of the second extension framework member in the vehicle width direction is located outward of the other end of the case in the vehicle width direction.

An electric vehicle battery replacement system having an ESS according to an embodiment of the present invention comprises: a battery containment facility for containing a discharged battery of an electric vehicle, and charging and storing the discharged battery; a battery transfer facility for transferring a pair of trays, in which a fully-charged battery that is fully charged by the battery containment facility is received, to a battery replacement place for the electric vehicle, and transferring the pair of trays, in which the discharged battery removed from the electric vehicle is received, into the battery containment facility; a power supply for supplying a driving power for each of the facilities; and a replacement facility operating terminal for providing a facility operating signal for each of the facilities, wherein the power supply receives, from a grid, a first power corresponding to a capacity price and a system marginal price set by the replacement facility operating terminal to use the received first power as a charging power for the discharged battery stored in the battery containment facility.

One or more switchable magnetic systems is located near a battery attachment surface of an electric vehicle, where the battery attachment surface is configured to accept and electronically connect to a battery pack. The electric vehicle also includes a control system that operates the one or more switchable magnetic system switching from a first to a second state. In the first state the magnetic field of the switchable magnetic system secures the battery pack to the battery attachment surface so that the battery pack is electronically coupled to an electric motor of the electric vehicle. When the control system receives a message corresponding to removal of the battery pack, the control system switches the switchable magnetic system to the second state such that the battery pack is removable from the battery attachment surface.

A method and system for swapping batteries in an electric vehicle is disclosed. The method includes dismounting a first battery assembly, moving to a second battery assembly and mounting the second battery assembly onto the vehicle. Mounting and dismounting are accomplished by an onboard mounting and dismounting system. The method can be used in a zero infrastructure environment such as an underground mine since mounting and dismounting are accomplished by components on the vehicle itself. An auxiliary battery pack powers the vehicle during between dismounting a battery pack and mounting another battery pack.

A vehicle side portion structure that includes: a pair of rockers that, at vehicle side portions, respectively extend along a vehicle longitudinal direction at both outer sides in a vehicle transverse direction of a floor panel that is a floor portion of a vehicle cabin interior, first impact absorbing portions that form closed cross-sectional structures and that, at a time of a side collision of a vehicle, plastically deform and absorb collision energy being provided at interiors of the pair of rockers; and side doors that open and close door opening portions of the vehicle side portions, second impact absorbing portions, which form closed cross-sectional structures and, at the time of a side collision of the vehicle, plastically deform and absorb collision energy, being provided at lower portions of interiors of the side doors.

An electric go-kart includes a frame and a crossbar. The crossbar is fixed to the frame and extends transversely to a left and right side of the frame. An accommodation box is rotationally coupled to each of the left and right side of the crossbar by a connector. A wheel is installed on an outer end of each accommodation box. A steering rod includes a one end fixed to the connector. A support rod is located at a front end of the frame. A stabilizing wheel is pivotably coupled to a front end of the support rod. A seat is fixed on a top side of the frame. A battery is located within the frame.

Provided are a battery locking/unlocking system, and an electric vehicle battery swapping control system and a control method thereof. The battery locking/unlocking system comprises a battery swapping device used for moving a battery; a lock shaft detection unit used for generating a location signal; a lock tongue control unit used for controlling a lock tongue to fall into the lock slot or retract to the outside of the lock slot; a data exchange unit separately communicates with the battery swapping device and the lock shaft detection unit. According to the battery locking/unlocking system and locking and unlocking control methods, by providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.

A concrete mixer truck includes a chassis, a plurality of tractive assemblies coupled to the chassis, a mixing drum rotatably coupled to the chassis, the mixing drum defining an internal volume configured to contain material and an aperture through which the material can enter and exit the internal volume, an energy storage device positioned at a rear end of the chassis and configured to provide electrical energy, and an electromagnetic device electrically coupled to the energy storage device, where the electromagnetic device is configured to receive the electrical energy from the energy storage device and provide mechanical energy to drive at least one of the plurality of tractive assemblies to propel the concrete mixer truck.
