BATTERY MONITORING APPARATUS, BATTERY MONITORING SUBSTRATE, BATTERY MODULE, AND BATTERY SYSTEM

摘要

A battery monitoring apparatus is provided with a base substrate disposed substantially parallel to a surface on which the electrodes of the cells of a battery are disposed, and a battery monitoring substrate disposed on the base substrate. The base substrate has: a plurality of connection terminals for establishing a connection to the battery monitoring substrate; a plurality of electrode terminals, each connected to an electrode of the cells of the battery; and a wiring pattern disposed between the connection terminals and the electrode terminals. The battery monitoring substrate has: a plurality of voltage detection terminals electrically connected to each of the connection terminals; a voltage detection circuit for detecting the voltage of the cells of the battery by detecting the voltage of each of the voltage detection terminals; and a balancing resistor for adjusting the capacity of the cells of the battery.
