Temperature compensation method in charging process of storage battery

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of battery charging. Background technique [0002] In the process of charging the battery, it is necessary to pay attention to the temperature change of the battery in time to ensure the normal charging and prevent the battery from being charged badly or failing to charge. At present, the temperature monitoring device and temperature monitoring method used to monitor the temperature change of the battery are too simple, and cannot well realize the purpose of adjusting the charging voltage in time according to the temperature change during battery charging. When the temperature is abnormal, the battery will be damaged. If the battery is badly charged or cannot be charged, the working efficiency during charging will be reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a temperature compensation method in the charging process of the stor...
