Method For Testing A Balanced Circuit
A method tests a balancing circuit for a battery having a plurality of battery cells. The method detects first voltage states of the battery cells by way of a control unit; activates the balancing circuit with the aim of achieving a voltage equalization of at least two of the battery cells; detects second voltage states of the battery cells by way of the control unit; and determines a functional capability of the balancing circuit based on the first voltage states and the second voltage states of the battery cells by way of the control unit.

- 1. A method for testing a balancing circuit for a battery that has a plurality of battery cells, the method comprising the steps of:
a) detecting first voltage states of the battery cells by way of a control unit; b) activating the balancing circuit for a purpose of achieving voltage equalization of at least two of the battery cells; c) detecting second voltage states of the battery cells by way of the control unit; and d) determining, by way of the control unit, a functional capability of the balancing circuit on the basis of the first voltage states and the second voltage states of the battery cells.
- 10. A device for testing a balancing circuit for a battery that has a plurality of battery cells, comprising:
a control unit operatively configured to execute a process that:
detects first voltage states of the battery cells;
activates the balancing circuit for a purpose of achieving voltage equalization of at least two of the battery cells;
detects second voltage states of the battery cells; and
determines a functional capability of the balancing circuit on the basis of the first voltage states and the second voltage states of the battery cells.
