Title:
BATTERY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/101005
Kind Code:
A1
Abstract:
The objective of the invention is to provide a battery pack reduced in size overall by eliminating current sensors. In order to solve the problem, the battery pack of the present invention has a configuration comprising: a battery group wherein a plurality of battery cells (lithium ion batteries 11, 12) are connected in series; a resistor (bus bar 20) connected in series to the battery group; voltage detection lines (voltage detection lines 101 to 104) disposed at the two ends of each of the battery cells (lithium ion batteries 11, 12) and the resistor (bus bar 20); and a battery controller connected to the voltage detection lines (voltage detection lines 101 to 104). One of the voltage detection lines (voltage detection lines 101 to 104) adjacent to one of the battery cells (lithium ion batteries 11, 12) has a terminal branching out to be connected to the battery controller.
