    摘要: A battery voltage Ef of a fuel cell 1 is detected, and a current instruction value which transformed an electric power instruction value Pfc of the fuel cell is reduced at falling-down of the voltage Ef. A current limiter 8 makes the current instruction value a limit value at the time of the falling-down of Ef, and reduces the limit value according to the fall of Ef. For example, current instruction value is restricted so as to begin to reduce battery current IFC at voltage drop alarm level (first threshold value), and become zero at voltage drop protection level (second threshold value).

    摘要: An objective of the invention is to deal with difference of the internal resistance of batteries.A battery system (1) including a plurality of battery modules (3) connected, wherein the higher the temperature of the location where the battery module (3) is located becomes, the larger the resistance value of a distribution cable (11) is made. In a chassis (2), the distribution cable (11) located where the temperature is high is made longer and the distribution cable (11) located where the temperature is low is made shorter. More specifically, the distribution cable (11) connected to a battery group (4) located on the upper part of the chassis is made longer and the distribution cable (11) connected to a battery group (4) located on the lower part of the chassis is made shorter. Further, the length of the distribution cable (11) may be adjusted by arranging the output terminal (21) on the lowermost part of the chassis (2).
