ABSTRACT:
The present invention provides an easy to produce cell voltage detecting apparatus using a semiconductor having low voltage endurance. In the cell voltage detecting apparatus, cell modules B1-B10are serially connected, a switch SW1is located at a middle point, and a contact point of the switch SW1on a higher potential side is set to a reference potential (ground). Each of discharge type constant current circuits VC1-VC10is connected to each of the cell modules B1-B10, and each of current-voltage converter circuits CV1-CV10is connected to each of the discharge type constant current circuits VC1-VC10. Also, diodes D6-D10are connected respectively so as to allow a current to flow in a direction from the current-voltage converter circuits SV6-SV10to the corresponding induction type constant current circuits VS6-VS10.
