    • 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).
    • 本发明的目的是处理电池内阻的差异。 一种电池系统(1),包括连接有多个电池模块(3),其中电池模块(3)所在位置的温度越高,配电电缆(11)的电阻值越大 。 在底盘(2)中,位于温度较高的分配电缆(11)较长,位于温度较低的分配电缆(11)较短。 更具体地,连接到位于机架上部的电池组(4)的分配电缆(11)制成得更长,并且配置电缆(11)连接到位于底座的下部的电池组(4) 底盘更短。 此外,可以通过将输出端子(21)布置在底架(2)的最下部分来调节配线电缆(11)的长度。
