A system for recharging an autonomous aerial vehicle includes a base, a supply boom, a receiving basket, a centering device, and a locking device. The supply boom includes a tip and first recharger. The receiving basket has an inner wall delimiting a cavity that may receive the tip of the supply boom. The receiving basket including a second recharger that is complementary to the first recharger. One of the supply boom and the receiving basket is mounted on the autonomous aerial vehicle while the other is mounted on the base. The centering device centers the tip of the supply boom in the cavity of the receiving basket. The locking device is controlled by a controller and locks the supply boom in the receiving basket.

The present disclosure provides an adapter assembly. Portion of the main body of the plug adapter is penetrated through the opening and exposed to the exterior of the accommodation space. Each protrusion is penetrated through the concave and exposed to the exterior of the accommodation space. Each protrusion exposed to the exterior of the accommodation space is connected with the position-limiting portion through the rotation of the plug adapter. Each fastening element is plugged into the first hole and the second hole. The plug adapter is fastened to the casing through the fastening element and the connection between the protrusion and the position-limiting portion. The adapter assembly includes two impact bearing points. One is formed by the fastening element, and the other is formed by the connection between the protrusion and the position-limiting portion. The stability and the waterproof capability of the adapter assembly are enhanced.

Methods and systems are disclosed configured to charge an electrical vehicle. A charge request is received for a first electrical vehicle parked at a first parking spot. A battery charging device is connected to a first head unit comprising a first charging cable located in proximity to the first parking spot. A charge request is received for a second electrical vehicle parked at a second parking spot. A determination is made as whether the first electrical vehicle is no longer being charged, and in response to determining that the first electrical vehicle is no longer being charged, the battery charging device is disconnected from the first head unit and is connected to a second head unit comprising a second charging cable located in proximity to the second parking spot.

A powertrain for electric and plug-in hybrid vehicle applications with integrated three-phase AC charging featuring buck-boost operation and optional vehicle-to-grid (V2G) capability, along with corresponding methods and machine instruction sets for switch control. The powertrain can include of a three-phase current source converter (CSC) front-end with an associated input filter, a polarity inversion module, and in an embodiment, a dual-inverter motor drive. The dual-inverter drive is the source of both the back emf and requisite DC inductance for the CSC. A compact design is thus provided as no additional magnetics are required and the on-board cooling system required for traction mode can be re-deployed for charging and V2G mode. The powertrain is mode shifted between charging and V2G mode through an optional polarity inversion module.
