摘要:
The disclosure describes a method for checking the proper method of operation of a current sensor which is designed to measure a battery current. During a precharge phase which begins at a time at which at least one electrical component is connected to a battery and during which the electrical component 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 disclosure also describes a computation unit and a battery which are designed to carry out the method according to the disclosure.
摘要:
The invention relates to a method for determining the life expectancy of at least one battery cell, according to which a value of at least one physical variable acting on the battery cell and/or a number of executions of at least one process taking place in the battery cell is determined, and the value of the physical variable and/or the number of executions of processes is used as a basis for determining the life expectancy. The physical variable and/or the number of executions of processes taking place in the battery cell is determined for a plurality of operating cycles, and the frequency (f) of the occurrence of defined values of the physical variable and/or the frequency (f) of the number of executions of at least one defined process is stored. The invention also relates to a battery, especially a lithium ion battery or a nickel - metal hydride battery, and to a motor vehicle comprising at least one battery according to the invention.
