Abstract
A voltage measuring apparatus is configured to measure voltages of respective battery cells of a battery cell array including a plurality of battery cell groups each including a predetermined number of battery cells connected in series. The voltage measuring apparatus includes a plurality of measuring units each provided for each of the battery cell groups. The adjacent measuring units are connected through a communication channel so as to perform current communication therebetween. A bidirectional diode circuit element is connected to the communication channel extending between the adjacent measuring units.
