A battery charge detection method and a charge detection device are provided. The method includes the steps: setting charge parameters and detection parameters of a battery (S1); detecting a current voltage of the battery (S2); detecting a voltage according to a preset time when the detected voltage of current battery is more than or equal to a full charge voltage (S41); when the detected voltage is less than the full charge voltage after the preset time and all sampled voltages are more than a charge critical voltage and do not follow a monotone increasing trend, obtaining current charge time of the battery, namely a first charge time (S8); comparing the first charge time with the rating charge time of the charge parameters; when the first charge time is more than the rating charge time, confirming that a charge fault occurs in charge course. The charge fault occurring in the battery charge course can be detected by using the method and the device. |
