    摘要： An electric vehicle (EV) charging system is described herein. The EV charging system may be configured to determine if a component in the EV charging system is operating properly based upon current usage. For example, an EV charging station controller may measure a current corresponding to an input to an EV charging station. The EV charging station controller may further measure currents of reference components in the EV charging station, and then use the measured currents to determine if a component in the EV charging station is operating properly. In some examples, the component is a heating, ventilation, and air conditioning (HVAC) component in an EV charging station because it is particularly useful to know the operational status of an HVAC in EV charging systems (e.g., to ensure that the components charging the EV are the correct temperature).

    摘要： An electric vehicle (EV) charging and cooling system is described that supplies electric power to charge an EV while simultaneously providing coolant to cool the charging components of the EV during the charging process. For example, the system includes a charging device that provides electrical power for charging a battery of the EV. The system also includes a coolant device that transfers coolant to the EV during charging for cooling the battery of the EV. The system also withdraws the coolant from the EV that has been used, and heated to a temperature that may not be suitable for cooling as a result of absorbing heat from the charging components. The system can cool the used coolant back to the cooled temperature to recirculate to the EV throughout a direct current (DC) fast charging process, which provides thermal stability and mitigates damage to the EV from overheating.

    摘要： A charging device includes a liquid cooled cable, a charging gun, a charging station, a station connector and a communicating pipe. The liquid cooled cable has a gun end and a station end. The liquid cooled cable includes a first insulating tube, a second insulating tube, a tape, a filler and a sheath. The first insulating tube has a first channel. The second insulating tube has a second channel and a braided copper mesh. The charging gun is connected to the gun end of the liquid cooled cable. The charging gun includes a gun connector and a first liquid return channel. The station connector includes a second liquid return channel and a connection part. One end of the second liquid return channel communicates to the second channel. The connection part is connected to the station end of the liquid cooled cable.

    摘要： A vehicle comprises a battery, a temperature adjustment unit, an inlet, a relay unit, a relay unit, a relay unit, and an ECU. When a power charging station is connected to the inlet, the ECU controls the relay unit to assume a closed position to perform external charging to charge the battery by the power charging station. When the ECU drives the temperature adjustment unit during the external charging and a component on a charging path at an electrical path located between a branch point and a branch point is higher in temperature than a threshold temperature, the ECU controls the relay unit to assume an open position and the relay unit to assume a closed position.

    摘要： A direct cooling method and system in charging system utilizing a water-based conductive fluid. The charging system includes a conductive fluid reservoir that provides conductive fluid to charging system components. The charging system further defines conductive fluid return paths for the conductive fluid. The length of a fluid path is specified to exceed a minimal resistance threshold based on the product of the resistivity and return path length. The system can include the incorporation of feedback loop into the charging system that can measure the electrical resistance of the conductive fluid.
