Abstract
In a method for monitoring a battery which includes a number of cells, in each instance, at least one electronic unit is situated so as to be in contact with at least two of the cells, in order to record a variable of this cell and forward it to a central receiver.
Claims13
A method for monitoring a battery of a motor vehicle which includes multiple cells, comprising:
- providing at least two electronic units;
- contacting each of the at least two electronic units with at least two of the multiple cells such that each cell is in contact with at least two of the electronic units, wherein each of the electronic unit is situated in or on a respective multiple cell of at least two of the multiple cells that it is contacting, wherein each cell of the multiple cells has a single electronic unit situated in or on the respective cell;
- and
- recording and transmitting, by at least one of the electronic units, at least one variable of at least one of the cells to a central receiver,
- wherein the electronic unit includes an oscillator situated in or on each cell for recording at least one of a temperature and a cell voltage as the at least one variable,
- wherein a frequency of the oscillator is a function of the at least one variable,
- wherein the at least one variables is transmitted to a central control unit, and
- wherein, to distinguish the at least two electronic units, the oscillation frequency is at least one of linked with or modulated to have a unique identification.
