Abstract
A battery module including at least one cell, at least one sensor, an interrupter device such as a fuse connected in series with the cells and an electronic switch. The electronic switch includes power transistors for short circuiting the series-connected components and the fuse if the sensor senses a malfunction and a diode for assuring that the power transistors maintain the series-connected circuit short circuited regardless of the subsequent status of the sensor. The diode memorizes the malfunction so that the module continues to conduct after the fuse blows, even if the sensors no longer detect any malfunction.
