Abstract
The shortage of energy prompts Li-ion battery to become the new alternative energy. In order to master battery characteristics, solve the battery safety problems and prolong service life, it is necessary to research essentially the battery performance, cycle life and capacity, which can provide the basis for the development of battery management system. In this paper, we build a set of Li-ion power battery testing system of charging and discharging according to the existing equipment, test the battery pack through a combination of the hardware and software, and put forward a set of complete testing method. Then on the basis of the test data and the relation curve between Li-ion power battery capacity and cycle times, we have proved that the testing system and testing method are effective.
