Abstract
A multi-module fuel cell system includes a plurality of fuel cell stacks, at least one battery connected to the plurality of fuel cell stacks, and a controller configured to determine whether the plurality of fuel cell stacks and the at least one battery are allowed to provide outputs in response to input of a required output, and controls either the plurality of fuel cell stacks or the at least one battery, selectively, to provide an output to satisfy the required output based on a result of determination as to whether outputs are allowed to be provided, and a method of controlling the same.
Claims20
A multi-module fuel cell system comprising:
- a plurality of fuel cell stacks;
- at least one battery connected to the plurality of fuel cell stacks;
- and
- a controller configured to:
- determine, based on input indicating a requested power output and based on at least one of a state of charge (SoC) of the at least one battery or a number of fuel cell stacks in the plurality of fuel cell stacks, one or more of the plurality of fuel cell stacks or the at least one battery allowed to provide power output and
- selectively control, based on the determined one or more of the plurality of fuel cell stacks or the at least one battery allowed to provide power output, either at least one fuel stack of the plurality of fuel cell stacks or the at least one battery to output power to satisfy the requested power output.
A method of controlling a multi-module fuel cell system comprising a plurality of fuel cell stacks and at least one battery, the method comprising:
- determining, by a controller of the multi-module fuel cell system and based on input indicating a requested power output and based on at least one of a state of charge (SoC) of the at least one battery or a number of fuel cell stacks in the plurality of fuel cell stacks, one or more of the plurality of fuel cell stacks or the at least one battery allowed to provide power output;
- and
- selectively controlling, by the controller and based on the determined one or more of the plurality of fuel cell stacks or the at least one battery allowed to provide power output, either at least one fuel cell stack of the plurality of fuel cell stacks or the at least one battery to output power to satisfy the requested power output.
A multi-module fuel cell system comprising:
- a plurality of fuel cell stacks;
- at least one battery;
- and
- a controller comprising:
- one or more processors;
- and
- a memory storing instructions that, when executed by the one or more processors, configure the controller to:
- monitor:
- a state of charge (SoC) of the at least one battery;
- and
- accumulated amounts of power output of each fuel cell stack of the plurality of fuel cell stacks;
- receive a request for power;
- and
- control, based on the request and whether the monitored SoC satisfies a SoC criterion, either:
- a fuel cell stack, of the plurality of fuel cell stacks and based on a corresponding accumulated amount of the monitored accumulated amounts, to satisfy the request;
- or
- the at least one battery to satisfy the request.
