The invention discloses a temperature compensation method in a charging process of a storage battery, which includes the following steps: presetting a standard temperature range and a normal temperature range in a single chip microcomputer, sampling a first initial temperature of the storage battery and a second initial temperature of a charging circuit unit and respectively storing the two initial temperature values which are eligible after comparison in a storage of the single chip microcomputer. In work, the single chip microcomputer compares real-time temperature of the storage battery with the normal temperature range and the standard temperature and timely increases or decreases charging voltage according to difference between the real-time temperature and the standard temperature. If the real-time temperature exceeds the normal temperature range, the single chip microcomputer adopts the real-time temperature value of a charging circuit unit as the evidence of temperature compensation in charging to finish the charging work. By means of the temperature compensation method, the charging voltage can be timely adjusted according to charging temperature of the storage battery, so that working efficiency of charging can be well guaranteed.
