Abstract

The invention discloses a real-time calculation method and system for the cycle index of an energy storage battery and a storage medium. The cycle index of the battery is obtained in real time throughanalysis and calculation of the load current of the battery and other data, and the method has the characteristics of being universal, high in efficiency and easy to operate.

Description

technical field [0001] The invention relates to a real-time calculation method for the cycle times of an energy storage battery, which belongs to the technical field of new energy and electric energy storage. Background technique [0002] The number of cycles is an important characteristic quantity of an energy storage battery, which is closely related to battery service life evaluation, state of charge (SOC) calculation, and state of health (SOH) analysis. At present, there are mainly methods such as charging and discharging times statistics and available capacity testing. The former calculates the number of cycles by counting the number of charging and discharging of the battery, which is limited to the complete charging and discharging process and cannot be generally applied; the latter estimates the number of cycles by detecting the available capacity and combining the test parameters provided by the battery manufacturer, which is only applicable to batteries In mainten...
