An automated valet parking method includes: activating an automated valet parking procedure, determining whether electrical charging of a vehicle is needed, setting a wireless charging service zone as a first target position when it is determined that the electrical charging of the vehicle is needed, transmitting the first target position and a first guide route leading to the first target position to the vehicle, setting an empty parking space as a second target position when the electrical charging of the vehicle is completed, and transmitting the second target position and a second guide route leading to the second target position to the vehicle.

An automated valet parking method includes: when charging of an electric vehicle is needed, performing: i) before providing a parking space to the electric vehicle, guiding, by a parking infrastructure, the electric vehicle to autonomously drive to a charging service zone, and ii) after charging of the electric vehicle is completed in the charging service zone, guiding, by the parking infrastructure, the electric vehicle to autonomously drive from the charging service zone to a first empty parking space in the parking lot. In particular, guiding the electric vehicle to the charging service zone before providing a parking space to the electric vehicle comprises: setting an empty space in the charging service zone as a first target position; and transmitting to the electric vehicle the first target position and a first guide route that guides the electric vehicle to the empty space in the charging service zone.

An automated storage and retrieval system includes a rail system, at least one vehicle operating on the rail system, at least one charging station on or at the perimeter of the rail system, and a control system. The rail system includes a first set of parallel rails extending in a first direction and a second set of parallel rails extending in second direction. The second direction is perpendicular to the first direction. The at least one vehicle includes at least one power storage source, and a local controller adapted to control movements of the at least one vehicle. The at least one charging station is adapted to be electrically connected with the at least one power storage source of the at least one vehicle. The control system is adapted to communicate with the local controller in the at least one vehicle and the at least one charging station. The control system is further adapted to, upon detecting a failure with the charging station, instruct the at least one vehicle to move to the at least one charging station such that the at least one power storage source of the vehicle electrically connects to the at least one charging station. The at least one charging station is further adapted to, transmit a charger diagnostic to the control system using power from the at least one power storage source of the at least one vehicle.

A battery connector for connecting a replaceable battery to an aerial vehicle, comprising a housing configured for fixing to one of the replaceable battery and the aerial vehicle. The connector element includes a first connection portion for releasable connection to an external connection element of the other one of the replaceable battery and the aerial vehicle and a second connection portion for fixed connection to the replaceable battery or the aerial vehicle. The connector element is supported in a horizontal direction in the housing by at least one flexible element positioned at least partly between the connector element and the housing and in a vertical direction in the housing by an upper flexible element positioned between an upper part of the connector element and the housing and a lower flexible element positioned between a lower part of the connector element and the housing.

Reactive replenishable device management comprises receiving device measurement data from at least one device, updating one or more device usage profiles associated with the at least one device, and if an analysis of the one or more device usage profiles indicates usage of the at least one device is sub-optimal, performing one or more of: controlling at least one of an attribute or an operation of the at least one device, issuing one or more device management recommendations to a user of the at least one device, and issuing one or more user alerts to the user. The at least one device comprises at least one of one or more replenishable devices, one or more replenishers associated with the one or more replenishable devices, and one or more other devices associated with the one or more replenishable devices.

A trailer can be configured to selectively provide powered wheels, energy recovery, and/or parasitic power source charging. A trailer-related trigger (drive activation trigger, an energy recovery trigger, or a parasitic charging trigger) can be detected. When a drive activation trigger is detected, one or more motors can be activated to power one or more wheels of the trailer, thereby providing extra pushing power. When an energy recovery trigger is detected, one or more power sources of the trailer can be charged by recovering energy from the trailer. When a parasitic charging trigger is detected, one or more power sources of the trailer can be charged using a portion of the power generated by a main vehicle operatively connected to the trailer.

An autonomous travel device is provided with wheels, a device main body, a power source that is provided on one end portion of the device main body within the device main body and causes the device main body to travel autonomously by driving the wheels, a battery for supplying power to the power source, and an accommodation unit for accommodating the battery from the other end portion of the device main body to a central portion of the device main body within the device main body. With this configuration, it is possible to easily perform replacement of the battery, and therefore, it is possible to perform autonomous travel that is stabilized due to disposition of the battery in consideration of the center of gravity of the device main body.

A vehicle body structure of an autonomous vehicle includes: a first driver integrally configured of a drive portion for a first wheel, a drive shaft for the first wheel and a first shaft support for the drive shaft; a second driver integrally configured of an axle for a second wheel and a second shaft support for the axle; and, a pair of side frames arranged on each side in a width direction of the chassis and each extended in a front-to-rear direction of the chassis to support the first driver and the second driver. The first shaft support and the second shaft support each have an attachment part to be fixed to a flank of the side frame from an outside. Each of the first and second drivers is integrally attached to, and detached from, the side frame, by access from the flank of the side frame.
