Abstract: A power ecosystem is disclosed that includes a premises power interface associated with a premises, a moving object power interface associated with a moving object, and an accessory power pack comprising an accessory sensor. The accessory power pack is configured to receive an electrical charge from the premises power interface, supply an electrical charge to the moving object power interface, and be releasably secured to the moving object. The accessory power pack is configured to send accessory sensor information captured by the accessory sensor to at least one of the premises or the moving object.

Abstract: An apparatus includes an inner rotor motor and a stationary wiring conduit. The inner rotor motor includes a stator and a rotor spaced at least in part radially inside the stator. The rotor is rotatable relative to the stator about an axis. The rotor includes a rotatable shaft that presents a shaft bore extending axially therethrough. The stationary wiring conduit extends through the shaft bore and is fixed relative to the motor housing. The shaft bore rotatably receives the wiring conduit, such that the wiring conduit is permitted to remain stationary as the shaft rotates.
