Abstract

The invention discloses an energy storage system testing method and device. The energy storage system test method comprises the following steps: controlling a first battery box to charge a second battery box; controlling the first battery box to discharge to a first preset electric quantity and controlling the second battery box to charge to a second preset electric quantity; wherein the first battery box comprises a plurality of battery clusters, and the second battery box comprises a plurality of battery clusters; controlling the second battery box to charge the first battery box; the first battery box is controlled to be charged to third preset electric quantity, and the second battery box is controlled to be discharged to first preset electric quantity; controlling the power grid to charge the second battery box to a second preset electric quantity; and controlling the battery management system to detect the capacity of the first battery box and the capacity of the second battery box. According to the technical scheme provided by the embodiment of the invention, the effects of testing the whole energy storage system and improving the detection accuracy of the energy storage system are achieved.

Description

technical field [0001] The present invention relates to the technical field of batteries, and in particular, to a method and device for testing an energy storage system. Background technique [0002] With the rapid development of battery energy storage systems, the performance requirements of battery energy storage systems are getting higher and higher. Therefore, it is necessary to carry out factory tests on battery energy storage systems. [0003] The existing tests of battery energy storage systems mainly test single cells or battery clusters composed of single cells, and cannot test the overall energy storage system and cannot reflect the actual working conditions of the energy storage system. The test accuracy of the system is low. SUMMARY OF THE INVENTION [0004] The present invention provides a method and device for testing an energy storage system, so as to test the entire energy storage system and improve the detection accuracy of the energy storage system. [...
