Device and method for determining operating parameters of a battery |
摘要 |
A device monitors the operating parameters of a battery, in particular a starter battery for an automobile. The operating parameters include at least the battery voltage and the device is supplied from the battery voltage. For power-saving and yet precise determination of operating parameters for the period of time which is particularly significant in practice after a drop in the battery voltage, the device comprises a battery parameter detection device which determines the operating parameters of the battery in an awake state, stores these in digital form and/or supplies them to a digital interface output. The detection device is inactive in a sleep state and has a reduced consumption of electricity. A cut-off detection device compares the battery voltage with the predetermined cut-off voltage during the sleep state and awakens the detection device from the sleep state if the battery voltage falls below the predetermined cut-off voltage.
