A power receiving and feeding apparatus is provided which includes a connector coupled to a power receiving and feeding outlet of an electric motor vehicle, a connector moving unit that moves the connector in a lateral direction and a vertical direction, and a position determination unit that determines a position of the power receiving and feeding outlet of the electric motor vehicle based on a position information of the electric motor vehicle and a vehicle information of the electric motor vehicle. The connector moving unit is caused to move the connector at a position higher than a predetermined height in the lateral direction and then in the vertical direction to align the connector to the position of the power receiving and feeding outlet so as to couple the connector to the power receiving and feeding outlet.

A battery block moving assembly for handling and a manipulation with a battery block is described. The battery block moving assembly includes a trolley, a platform, a lift mechanism and a battery block moving mechanism. The battery block moving mechanism includes a pin and a horizontal pin moving mechanism configured to move the pin. The pin is configured to engage and move a battery block.

Systems and methods are provided for end-to-end infrastructure for supporting use of swappable batteries in electric vehicles. An end-to-end infrastructure for supporting use of electric vehicles may include one or more battery-swapping fueling stations. Each battery-swapping fueling station is configured to maintain one or more swappable batteries configured for operation in the electric vehicles, charge each of the one or more swappable batteries, when not fully charged, and swap, using the one or more swappable batteries, at least one battery of at least one electric vehicle when the at least one electric vehicle is refueling at the battery-swapping fueling station.

A battery-retention system employs a retention jaw assembly and a battery-retention mechanism to secure a battery within a battery compartment of a material-handling vehicle. The retention jaw includes a battery-contact portion operatively associated with a barrier portion that is movable between a battery-retention position when the battery contacts the battery-contact portion and a battery-release position when the battery does not contact the battery-contact portion. The battery-retention mechanism includes a stopper block that is operable to be positioned within the battery compartment when the battery compartment door is in a closed position and operable to be positioned external to the battery compartment when the battery compartment door is in an open position.

A vehicle battery exchange system includes: a battery charger configured to store multiple batteries therein, and including a first battery locking device that is configured to be unlocked when each of the batteries is withdrawn from the battery charger and is configured to be locked when the batteries are stored in the battery charger, the battery charger charging a battery among the stored batteries when a state-of-charge of the corresponding battery is insufficient; and a server configured to: communicate with the battery charger and a vehicle and guiding the vehicle to a position of the battery charger when a charge request is received from the vehicle, control the first battery locking device to be unlocked when the vehicle is authenticated, and control the first battery locking device to be locked when exchange of batteries between the authenticated vehicle and the battery charger is completed.

A cart with powered folding and unfolding capability is provided. The cart has a cradle for holding a load, a frame supporting said cradle, said frame including a U-shaped leg member defining a pair of free ends connected to said cradle and a cross-bar end connected to a pair of wheels for ground engagement to enable said cart to roll along the ground, at least one leg pivot motor coupled to said leg member to enable powered folding of said leg member with respect to said cradle. The cart has a battery disposed on said cradle to power said leg pivot motor to enable powered folding and unfolding of said leg member. The cart also has an actuator disposed on said frame to initiate powered folding or unfolding of said leg member. Such a cart may also include a pair of auxiliary legs which are capable of powered folding.
