Abstract
A car battery system includes a plurality of battery cells, each battery cell having a positive electrode terminal and a negative electrode terminal, a battery block that retains the plurality of battery cells in a stacked configuration and has a terminal surface that is formed by battery cell terminal surfaces established by the positive and negative electrode terminals, and a battery state detection circuit that is connected to the electrode terminals of each battery cell to detect the condition of each battery cell. The positive and negative electrode terminals of each battery cell are connected to a circuit board and to the battery state detection circuit. The circuit board is connected to the positive and negative electrode terminals of each battery cell via voltage detection lines, and the voltage detection lines are connected to the same locations on the electrode terminals of each battery cell.
