Abstract

The invention discloses a charging voltage threshold determining method and a charging strategy determining method, wherein the charging voltage threshold determining method includes: charging a battery with a preset current value; obtaining the target of the positive electrode voltage corresponding to the inflection point of the negative electrode voltage of the battery Voltage value: determining the target voltage value as the charging voltage threshold when the battery is charged by the preset current value. The method for determining the charging voltage threshold and the method for determining the charging strategy provided by the present invention can quickly and safely determine the charging voltage threshold of the battery when charging with different currents.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method for determining a charging voltage threshold and a method for determining a charging strategy. Background technique [0002] Rechargeable lithium-ion batteries are the most widely used batteries in electronic devices such as mobile phones and notebook computers. Lithium-ion batteries must not be overcharged or over-discharged during use (it will damage the battery or make it scrapped). Therefore, there are protective components or protective circuits on the battery to prevent expensive battery damage. The charging requirements of lithium-ion batteries are very high, and the accuracy of the termination voltage must be guaranteed to be within ±1%, so it is particularly important to determine the charging threshold of lithium-ion batteries. [0003] In the prior art, low temperature and normal temperature cycle tests are generally used to determine the charging voltage t...
