Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

Communication systems and methods for hydrogen fueling and electric charging

The invention relates to a large-scale hydrogen refueling station comprising at least one supply storage, a plurality of compressor modules comprising a local controller, a plurality of dispenser modules, and a hydrogen production system comprising a hydrogen production system controller mutually connected by one or more flow paths. Wherein one of the controllers facilitates control of valves and thereby flow of hydrogen gas in the flow paths between the at least one supply storage, compressor modules, dispenser modules and hydrogen production system. Wherein the control of the valves enables flow of hydrogen gas in at least three of the flow paths simultaneously.

Large-scale hydrogen refueling station

The invention related to a system for control of a hydrogen refueling station. The control of the hydrogen refueling station is optimized according to a high frequency tank profile in a time period between time A and time B. The high frequency tank profile includes selecting a first of the plurality of vessels as supply to the compressor during at least part of the refueling of the vehicle tank, the selection is based on pressure of hydrogen gas in one or more vessels of the supply storage. The control of the hydrogen refueling station is furthermore optimized according to a low frequency tank profile in a time period between time C and time D. The low frequency tank profile includes preparing one or more hydrogen refueling station components to enable a plurality of vehicle tank refuelings in the subsequent time period between time A and time B.

Control of a hydrogen refueling station

A control method is provided for a filter system, which includes at least one filter element (). The method includes continuously recording a total energy consumption (E) during a filtration cycle () of the filter system. The total energy consumption (E) includes at least of the energy consumption (E) for a physical cleaning () and the energy consumption (E) for the subsequent production cycle () up to a predefined, in particular current point in time. The method further includes computing a relative energy consumption (E) by way of division of the recorded total energy consumption (E) by a net permeate volume (Q) which has been produced during the filtration cycle () up to the predefined point in time and starting a physical cleaning () in dependence on the relative energy consumption or of a characteristic value derived from this.

a filtering method, with which a fluid to be filtered is led through a filter (), the filter () is back-flushed at regular time intervals and a pre-treatment agent is added to the fluid at the entry side of the filter. A process variable which describes the efficiency of the filtration is continuously computed during the filtration, and a metering quantity of the pre-treatment agent is reset on the basis of the values for the process variable or a characteristic values derived from this.
