Abstract
Provided are a method and system for charging a battery using a fuel cell. The method includes: running the fuel cell; setting a voltage input from the fuel cell as a preset first input adapting voltage (1st LAV), when the input power from the fuel cell is lower than the output power to the battery; detecting whether an output current to the battery reaches a first low detect current (1st LDC) while the battery is being charged based on the first input adapting voltage; and resetting the first input adapting voltage based on a detection result.
Claims18
A method for charging a battery using a fuel cell, the method comprising:
- running the fuel cell;
- setting a voltage input from the fuel cell as a preset first input adapting voltage (1st IAV), when the input power from the fuel cell is lower than the output power to the battery;
- detecting whether an output current to the battery reaches a first low detect current (1st LDC) while the battery is being charged based on the first input adapting voltage;
- and
- controlling the voltage input from the fuel cell to remain constant by resetting the first input adapting voltage based on a detection result,
- wherein the controlling step comprises:
- resetting the first input adapting voltage to a second input adapting voltage (2nd IAV) if the output current reaches the first low detect current;
- and
- maintaining the first input adapting voltage if the output current does not reach the first low detect current.
