Abstract
A method for controlling a stack and battery output to improve durability of a fuel cell stack and an apparatus therefor. A method for distributing an output in a vehicle fuel cell system including a fuel cell (FC) stack and a high voltage battery includes collecting information about a driving route to a destination and traffic congestion information for each road section corresponding to the driving route, dividing the driving route into a first section and a second section based on the traffic congestion information for each road section, and applying different output distribution strategies to the first section and the second section.
Claims20
A method performed by an apparatus of a vehicle, the method comprising:
- obtaining information about:
- a driving route of the vehicle to a destination, and
- traffic congestion information for each of a plurality of road segments, wherein the plurality of road segments are associated with the driving route;
- dividing, based on the traffic congestion information, the plurality of road segments into a first section and a second section;
- generating a signal indicating a first output distribution strategy for the first section and a second output distribution strategy for the second section;
- and
- controlling, based on the signal, operation of a fuel cell stack of the vehicle and operation of a battery of the vehicle.
An apparatus of a vehicle, the apparatus comprising:
- a processor;
- and
- a memory storing at least one instruction that, when executed by the processor communicating with the memory, is configured to cause the apparatus to:
- obtain information about:
- a driving route of the vehicle to a destination, and
- traffic congestion information for each of a plurality of road segments, wherein the plurality of road segments are associated with the driving route,
- divide, based on the traffic congestion information, the plurality of road segments into a first section and a second section,
- generate a signal indicating a first output distribution strategy for the first section and a second output distribution strategy for the second section, and
- control, based on the signal, operation of a fuel cell stack of the vehicle and operation of a battery of the vehicle.
A vehicle comprising:
- a battery;
- a fuel cell stack;
- a processor;
- and
- a memory storing at least one instruction that, when executed by the processor communicating with the memory, is configured to cause the vehicle to:
- obtain information about:
- a driving route of the vehicle to a destination, and
- traffic congestion information for each of a plurality of road segments, wherein the plurality of road segments are associated with the driving route,
- based on the traffic congestion information, classify the plurality of road segments into a first section and a second section, wherein the first section and the second section are defined based on the destination,
- apply, during the vehicle driving in the first section, a first output distribution configured to control ON/OFF of the fuel cell stack to reduce a switching frequency of the fuel cell stack and adjust a charging/discharging range of the battery, and
- apply, during the vehicle driving in the second section, a second output distribution configured to control ON/OFF of the fuel cell stack such that a state of charge (SoC) of the battery satisfies a target SoC of the battery upon the vehicle arriving at the destination.
