Abstract: A system for protecting a device having variable internal resistance includes a protection fuse capable of blowing when a current having an intensity greater than an intensity threshold passes through. The system also includes an estimator suitable for estimating the internal resistance of the device, and a safety device suitable for limiting and/or preventing use of the device when the internal resistance is greater than a resistance threshold beyond which the protection fuse is inoperative.

Abstract: A method is for determining and resetting the state of charge of at least one battery of a hybrid vehicle including a first battery, a second battery and a heat engine. The method includes, during a standby phase of the vehicle, a first step of charging the first battery via the second battery, during which: (i) the first battery is charged; (ii) the value of its voltage is measured; (iii) the value of the voltage of the first battery is compared with a threshold voltage value corresponding to a maximum state of charge of the first battery; and (iv) when the threshold voltage value is reached, stopping the charging of the first battery, determining that it is in a maximum state of charge and setting a value of its state of charge to maximum state of charge, and otherwise continuing to charge.
