A method for detecting the operability of a load switch of a battery and a battery with a device for detecting the operation of a load switch of the battery

摘要

The battery (1) according to the invention with a device for detecting the functioning of a load switch (3) of the battery (1) comprises a first battery pole (5) which is set up via a first switch (2) with a first contact (9) of a Capacitor (7) to be electrically conductively connected, a second battery pole (6) which is adapted to be electrically conductively connected via the load switch (3) to a second contact (10) of the capacitor (7), a first switching means, the is arranged to apply a switching signal to the load switch (3), which is suitable for switching the load switch (3) in an open state, a second switching means, which are adapted, the first switch (2) for the duration (t) of a predetermined To close a test interval, a measuring means which is adapted to detect a voltage applied to the capacitor (7) capacitor voltage during or after the test interval, and an evaluation unit, the ei is directed to evaluate the functioning of the load switch (3) as not given when the capacitor voltage is greater than or equal to a threshold voltage.
