A fluid delivery system includes one or more smart hoses. A smart hose of the one or more smart hoses includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose.

Aspects of the disclosure provide a battery pack and a method for charging the battery pack externally. The battery pack can include a charging port configured to charge the battery pack, a cooling circuit configured to cool the battery pack in a vehicle, and a cooling interface configured to connect the cooling circuit with an external cooling device that is external to the vehicle. The charging port and the cooling interface can be integrated into a charging port assembly, the cooling interface has an inlet port and an outlet port that have high pressure quick disconnect leakless fittings, and the battery pack is configured to be charged externally via the charging port. The battery pack can include a plurality of isolating devices configured to determine whether the cooling circuit is connected to the external cooling device.

The present disclosure provides an electrical connector comprising a housing and a radiator. The radiator is disposed on the housing, comprising a fluid flowing space, a fluid input port, and a fluid output port. The fluid input port and the fluid output port are communicating with the fluid flowing space. Fluid flows through the fluid input port to the fluid flowing space. The fluid absorbs the thermal energy generated by a mating connector plugged into the electrical connector. The fluid absorbing the thermal energy generated by the mating connector flows through the fluid output port to external.

A surrogate component for a test system is described. The surrogate component may comprise: a body, comprising, a first shell comprising a plurality of exit holes; and a second shell coupled to the first shell, wherein the second shell comprises a first connection interface and a second connection interface; and a wiring harness, comprising: at least one data communication line coupled to the first connection interface and passing through one of the plurality of exit holes; and at least one power line coupled to the second connection interface and passing through the one of the plurality of exit holes.

A supply device for supplying a device that can be moved on a driving surface with a material supplied through a supply line. The supply device has a plug with an electric plug contact element that extends along a plug axis and is coupled to a plug receptacle of the mobile device by a linear joining movement, and a supply line with a valve, and detects a coupled state of the plug with the plug receptacle by an electric plug contact element. In the coupled state the valve is actuated. The supply device has a nozzle arranged on the supply line and is coupled to an inlet port of the mobile device. A feeding holder keeps the nozzle and the plug in a defined position and orientation relative to each other so that when coupling the plug to the plug receptacle the nozzle couples to the inlet port. The movement device makes the feeding holder with the plug and nozzle at least height adjustable and movable in the direction of the joining movement along a joining axis. The detection system determines a position of the plug receptacle. The supply device couples the plug to the plug receptacle and thereby the nozzle to the inlet port by a linear joining movement along the joining axis based on the determined position.
