Abstract (en)
[origin: WO2021058278A1] The invention relates to a system for protecting a device (20) having variable internal resistance, comprising a protection fuse (25) capable of blowing when a current having an intensity greater than an intensity threshold passes through. According to the invention, the system further comprises estimation means suitable for estimating the internal resistance of the device, and safety means 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.
