Aiming at the healthy charging goal of lithium-ion battery, a constant voltage supplementary method for lithium-ion battery was explored. Combined with the lithium-ion battery charging management process, the constant supplementary charging for lithium-ion battery was achieved based on the feedback control theory. The method was used for exploration applications in ground maintenance equipment of the developed airborne battery, applying for the lithium-ion battery charging maintenance, activating charge and discharge cycles. The experimental results show that the method is able to achieve better constant supplementary charge in the charging process, in which the charging rate is increased by 20% than the original limited-voltage supplementary charging way. When supplementary changing the battery, the battery temperature is maintained within an appropriate range, and the charging efficiency,the charging time and other parameters are improved effectively. The method has a certain role to extend the lithium-ion battery life.
