The invention relates to a method for generating and delivering charging current for an electric vehicle in a charging pole having the method steps of registering a first initial process, evaluating the first initial process, starting the charging process as a function of the evaluation result, the first initial process being different from a start command of a user for starting a charging process, and a charging pole for carrying out the method.

A fuel cell vehicle is mounted with a fuel cell system including a fuel cell stack and a battery. The fuel cell vehicle controls operation of the fuel cell system with an ECU, to perform standby power generation from activation to when travel is allowed and to perform power generation during operation of the fuel cell vehicle after travel has been allowed. In an activation method, the power generation current is increased in accordance with a low-temperature efficiency rate during the power generation during operation, the battery is charged and the power generation current is increased in accordance with a standby current increase rate that is lower than the low-temperature efficiency rate during the standby power generation.

An airship and its long-term floating capacity maintenance method are disclosed. The airship includes an airship capsule and a pod at bottom. A renewable fuel cell and a water tank communicated with each other are arranged in the pod. The water tank is provided with a water inlet connected with a filling aircraft outside the airship. The airship capsule is provided with a solar cell. The interior of the airship capsule is provided with a hydrogen storage bag. The solar cell is electrically connected with the renewable fuel cell. The renewable fuel cell can use electric energy provided by the solar cell to electrolyze water provided by the filling aircraft into hydrogen and supplement the hydrogen to the hydrogen storage bag. The airship can supplement hydrogen to the airship capsule by electrolyzing water to reduce the phenomenon of insufficient gas in the airship capsule.

A gaseous hydrogen storage and distribution system with a cryogenic supply and a method for the cryogenic conversion of liquid hydrogen into high-pressure gaseous hydrogen are provided. The gaseous hydrogen storage and distribution system includes pressuring liquid hydrogen from a cryogenic tank using a low pressure liquid pump before vaporization within a relatively small vaporizer. The resulting high pressure gaseous hydrogen is transferred to a plurality of storage tanks at ambient temperature according to a desired fill sequence. The high pressure hydrogen gas is subsequently distributed from the storage tanks through a hydrogen fueling dispenser according to a desired dispensing sequence. The present system and method provide improvements in operational safety, eliminates the use of high pressure gas compressor, and minimizes boiling off and ventilation losses at a reduced cost when compared to existing thermal compression storage systems.

A system for reducing overdraw of power in a vehicle includes a power source having a battery and a fuel cell circuit. The system further includes an ECU that transmits a power limit signal to a vehicle controller, the power limit signal corresponding to an instantaneous maximum amount of power of the power source. The ECU also determines a battery allowed power corresponding to an amount of power available to be drawn from the battery to cause the SOC of the battery to remain above a lower SOC threshold. The ECU also determines a current battery power draw from the battery corresponding to an instantaneous amount of power being drawn from the battery. The ECU is designed to reduce the instantaneous maximum amount of power in the power limit signal when the current battery power draw is greater than the battery allowed power, reducing the current battery power draw.
