Abstract (en)
[origin: WO2011144508A2] The invention relates to a circuit for a battery which has a number n of battery cells (10-1,..., 10-n) which are connected in series between a positive battery terminal (12) and a negative battery terminal (13). The number n is a natural number greater than 1. Due to the mounting in series of the n battery cells (10-1,..., 10-n), a number (n-1) of connection points (11 -1,..., 11 -n-1 ) are obtained between the n battery cells (10-1,..., 10-n). Said circuit comprises a discharge element (30) comprising a first terminal which is connected or can be connected to a first discharge line (14-1) and a second terminal which is connected or can be connected to a second discharge line (14-2). According to the invention, the circuit comprises a number (n+1) of switches (20-1,..., 20-n+1 ) which can be connected at a first terminal to a respective (n-1) connection point (11-1,..., 11-n-1) or to one of the positive or negative battery terminals (12; 13) and are connected at a second terminal to the first or second discharge line (14-1; 14-2). A positive pole of a respective battery cell (10-1,..., 10-n) can thus be selectively connected by one of the switches (20-1,..., 20-n+1 ) to the first or second discharge line (14-1; 14-2) and a negative pole of the respective battery cell (10-1,..., 10-n) can be connected by one of the switches (20-1,..., 20-n+1) to the remaining first or second discharge lines (14-1; 14-2). The invention also relates to a battery with said type of circuit.
