PROBLEM TO BE SOLVED: To provide a battery pack control device that restrains the use region of a battery pack from getting smaller.SOLUTION: A battery pack control device controls a battery pack 200. The battery pack control device comprises a communication line, a plurality of monitoring ICs, a microcomputer, a plurality of insulation elements 40, and a variable resistor 90. The monitoring ICs detect voltage of respective battery blocks 220. The microcomputer communicates with each of the monitoring ICs. Each of the insulation elements 40 is provided between each monitoring IC and the microcomputer, and communicates data. The insulation element 40 consumes power of the monitoring IC by communicating the data. The variable resistor 90 increases power consumption of a monitoring IC to which power is supplied by a small consumption block, and thereby restrains variations of power consumed in each battery block 220 due to operation of the monitoring ICs.SELECTED DRAWING: Figure 2

    【課題】組電池の使用領域が狭くなるのを抑制する組電池制御装置を提供する。【解決手段】組電池制御装置は、組電池200の制御を行う。組電池制御装置は、通信線と、複数の監視ICと、マイコンと、複数の絶縁素子40と、可変抵抗90と、を備えている。監視ICは、電池ブロック220の電圧を検出する。マイコンは、各監視ICと通信を行う。絶縁素子40は、監視ICとマイコンとの間に設けられ、データを伝達する。絶縁素子40は、データを伝達することにより、監視ICの電力を消費する。可変抵抗90は、小消費ブロックから電力が供給される監視ICの消費電力を大きくし、監視ICの動作に伴い各電池ブロック220で消費される電力のばらつきを抑制する。【選択図】図2
