Abstract | The invention provides an anti-condensation dehumidification method and a power battery system thereof. The anti-condensation dehumidification method comprises the steps that parameters including the temperature of the inner wall of the power battery system and the temperature, humidity and pressure of the internal environment of a power battery are collected in real time; the dew point temperature is calculated according to the collected parameters; the conditions for determining whether dehumidification is started or not are as follows: when the inner wall temperature is greater than the dew point temperature, or when the inner wall temperature is smaller than or equal to the dew point temperature, the real-time insulation resistance value is larger than the set insulation resistance value, and the internal insulation resistance value variation dR/dt is larger than or equal to 0, dehumidification is not started; when the inner wall temperature is less than or equal to the dew point temperature, the real-tim |
