Energy storage battery test method

Abstract

The invention relates to the field of power technologies, in particular to an energy storage battery test method. The method includes: recording probability of actual power of an energy storage battery in both a charge power subsection and a discharge power subsection; combining the power sections into a power section according to the probability of the actual power in the power subsections; calculating test power and test time for the actual power in the power section; subjecting the energy storage battery to preset times of charge and discharge tests according to the test power and test time. The energy storage battery test method has the advantages that the energy storage lithium battery pack can be provided with a cycle life test method based on typical operation conditions, performance aging condition of the energy storage lithium battery pack in three modes, namely track designated generation, wind-solar power smoothing and peak load shaving, can be tested, guidance is provided for the production, operation and maintenance of energy storage lithium batteries, and safe, stable and efficient operation of a lithium battery energy storage system is ensured.

Description

Technical field [0001] The invention relates to the field of electric power technology, in particular to a detection method for energy storage batteries. Background technique [0002] With the problems of intermittent, volatility and power quality brought about by the development of new energy, energy storage technology has received more and more attention. However, there is no in-depth study on the life of energy storage batteries and the problems that may arise during use, and there is a lack of corresponding research methods. [0003] Since the energy storage battery is used for charging and discharging for a long time, none of the existing battery performance test methods are applicable; and the energy storage battery needs to test the power parameters of the battery, which increases the difficulty of the test. Summary of the invention [0004] To provide test methods for studying the life and performance of energy storage batteries, to solve the problem of performance degradat...
