TEST SYSTEMS, TEST METHODS AND MEDIUMS FOR ENERGY STORAGE MANAGEMENT SYSTEMS OF PHOTOVOLTAIC CHARGING PILES

A test system and method, and a medium for an energy storage management system of a photovoltaic charging pile are provided. The test system comprises an analog unit, a test switch unit, an acquisition unit, and a processor. The processor is configured to: generate and execute a first acquisition instruction, in response to determining that a first performance feature set does not satisfy a first preset condition: generate a test start instruction and send the test start instruction to the test switch unit when an external load is null, and enable a test circuit composed of the analog unit and an energy storage device to be conducted; in response to determining that the test start instruction is executed and completed, generate a second acquisition instruction and a third acquisition instruction and send the second acquisition instruction and the third acquisition instruction to a battery management system (BMS) and the acquisition unit; determine a second test feature based on test sensing data; in response to determining that a first test feature and a second test feature satisfy a second preset condition, generate first warning information; and in response to determining that the first test feature and the second test feature do not satisfy the second preset condition, generate second warning information and/or generate an accuracy adjustment instruction and send the accuracy adjustment instruction to the BMS.
