description Provided is a zero-load low-loss battery charging circuit. The zero-load low-loss battery charging circuit comprises an EMI module, a charging interface module, a charging main control module, a charging processing module and an auxiliary power supply module, wherein the EMI module is used for filtering high frequency interference signals of an AC; the auxiliary power supply module is used for performing rectification step-down processing on the AC outputted by the EMI module so as to output a fist DC voltage to the charging main control module and output a second DC voltage to the charging processing module; and the charging processing module is used for detecting whether the charging interface module is connected with a battery and whether the battery is fully charged, when detecting that the charging interface module is connected with the battery, driving the charging main control module to receive the first DC voltage so as to enable the charging main control module to be at a working state, and when the
