Abstract
The present disclosure provides a battery detection device. The detection circuit is disposed on the battery and produces an impedance value variation quantity according to a deformation of the battery. The detection circuit includes four connection nodes. The first connection node and the third connection node are connected with the battery. A voltage variation quantity is produced between the second connection node and the fourth connection node according to the impedance value variation quantity. The protection circuit is connected with the second connection node and the fourth connection node. The protection circuit is in an ON state when the voltage variation quantity is greater than or equal to a cut-off voltage. The protection circuit is in an OFF state when the voltage variation quantity is less than the cut-off voltage, so that an operation state of the battery is changed accordingly.
