A method of controlling battery replacement includes obtaining information on a battery (first battery) and giving a notification that encourages battery replacement to a user of an electrically powered vehicle when a battery (second battery) lower in SOC than the battery is provided at a battery station (battery replacement station). The method of controlling battery replacement includes controlling the battery station such that the battery and the battery lower in SOC than the battery are replaced with each other.

A motorised scooter comprises a framework for supporting a rider; a ground engaging element connected to the framework for moving the rider; an engine connected to the ground engaging element for propelling the ground engaging element; and a brake further connected to the framework, the ground engaging element, the engine or a combination of any these for stopping the motorised scooter. A method for using the motorised scooter comprises a step of a first step of receiving a request to use at least one motorised scooter; a second step of notifying location of the at least one suitable motorised scooter; a third step of offering the at least one suitable motorised scooter; and a fourth step of getting back the at least one suitable motorised scooter.

A unmanned aerial vehicle (UAV) base station for automated battery pack exchange and methods for manufacturing and using the same. The UAV base station includes a battery-exchange system disposed within a housing having a top-plate. The housing contains a battery array having a plurality of UAV battery packs and a mechanical mechanism for automatically removing an expended battery pack from a UAV that lands on the top-plate and replacing the expended battery pack with a charged battery pack. Thereby, the UAV base station system advantageously enables extended and autonomous operation of the UAV without the need for user intervention for exchanging UAV battery packs.

A storage system includes a charging station assembly for charging a plurality of power sources and a method thereof. The charging station assembly includes a charging station support fixing the charging station assembly to a base of the storage system, a plurality of charging stations, each charging station including a charger that charges the plurality of power sources and a power source transport device enabling relocation of the power source between an operational position on a remotely operated vehicle and a charging position in or at any one of the plurality of charging stations.
