METHOD FOR CHECKING THE PROPER METHOD OF OPERATION OF A CURRENT SENSOR

摘要

The invention describes a method for checking the proper method of operation of a current sensor (26, 28) which is designed to measure a battery current. During a precharge phase (32) which begins at a time (34) at which at least one electrical component (20, 22, 24) is connected to a battery (100) and during which the electrical component (20, 22, 24) is precharged by a precharge current, at least one measured value provided by the current sensor is compared with an expected current value determined from an expected temporal profile of the precharge current. The invention also describes a computation unit and a battery (100) which are designed to carry out the method according to the invention.
