Abstract
The invention concerns a protective circuit ( ) for protecting a rechargeable battery ( ) against currents of too high intensity. The protective circuit ( ) includes detection and comparison means ( ) for generating a control signal (OVRC) in response to the comparison of a reference voltage (V ) and a measuring voltage (V ) representative of the charge or discharge current (I , I ) passing through the battery ( ). According to the invention, the detection and comparison means ( ) include adjustment means ( ) for compensating a temperature dependence of the measuring voltage (V ) and/or the reference voltage (V ), these adjustment means ( ) including means for generating diode voltages (V to V ).
