<p>An electrical bypass device for a battery is provided for isolating and bypassing a defective battery module made up of secondary cells to allow the battery to continue operating under slightly degraded conditions. The bypass device comprises a first actuator and a second actuator which trigger when a module becomes defective. The actuators each comprise a first, second and third terminal. The first and second terminals are electrically connected to the output terminals of the secondary cells, and the third terminal can be switched between the first and the second terminal. Switching over of the third terminal of an actuator occurs when the actuator is triggered. Triggering (intentional or inadvertent) of one of the actuators leads automatically to triggering of the other actuator if the latter has not triggered.</p> |
