Document Type and Number:
Japanese Patent JP2023018328
Kind Code:
A
Abstract:
To provide a power storage system, an electric device, and a control device, which limit transmission and reception of power between assembled batteries when an abnormality relating to the power transmission or power reception between the series-connected assembled batteries is detected.SOLUTION: In a battery pack 100, battery modules 112 to 116 include: a power transmission/reception unit for transmitting and receiving power between the battery modules; a high-potential bus 144 electrically connected to positive electrode terminals of the battery modules and electrically connected to positive electrode terminals of other battery modules via the transmission/reception units; a low potential bus 142 electrically connected to negative electrode terminals of the battery module and electrically connected to negative electrode terminals of other battery modules via the transmission/reception unit; and an abnormal operation protection element arranged between the positive electrode terminals of the battery modules and the high-potential buses or between the negative electrode terminals of the battery modules and the low-potential buses and limits the transmission/reception of the power via the transmission/reception units between the battery modules.SELECTED DRAWING: Figure 1
