PS3 Controllers Not Charging Anymore

Hello, I have two controllers that suddenly stopped charging. I plugged them in via USB but they are not being detected anymore. I reset the controllers but nothing works. Is it possible to modify the settings so that the controllers cannot be charged? I'm asking this because my ex returned my console. I tried the console to see, it works, the controllers too, and then suddenly when I wanted to charge them, nothing; they are not detected anymore. For your information, her son is a modder and has modified my console. Can you please help me? Thank you very much in advance.
