  "textContent": "This application discloses an energy storage system and an insulation detection method therefor. According to embodiments of this application, the insulation detection method includes: turning on a main positive relay and a main negative relay in a high voltage safety box (222) of each electric cabinet (22) in the energy storage system (2); controlling the insulation detection board (212) to perform insulation detection on the energy storage system (2) at a main power management system (211), and to report an insulation detection result to a power conversion system (23); controlling, if the insulation detection result at the main power management system (211) indicates no fault and no instruction of starting insulation detection at the power conversion system (23) is received, the insulation detection board (212) to continue performing the insulation detection on the energy storage system (2) at the main power management system (211); and instructing, if the insulation detection result at the main power management system (211) indicates an insulation fault, a battery management system (221) of each electric cabinet to control the main positive relay and the main negative relay in the high voltage safety box (222) to turn off. This technical solution solves the problem of false reporting of faults that is likely to occur in the prior art when the insulation detection is performed on the energy storage system (2) at the power conversion system (23) and the main power management system (211) concurrently.",
