  • Battery System
    Publication number: 20140117762
    Abstract: 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).
