Abstract
Embodiments of the present application provide an energy storage system and a self-start method thereof. The system includes a power conversion system; a DC bus; n single racks, where n is a natural number, and n is greater than or equal to 1; a host computer, connected to each of the n single racks; and a master battery management unit, connected to each of the n single racks, where each of the n single racks includes a first miniature circuit breaker, a DC/DC power module, a slave battery management unit, a wake-up relay, a main positive high voltage relay, a main negative high voltage relay, a CSC module, and a battery box. The technical solutions provided in the embodiments of the present application can resolve the problem that an energy storage system cannot self-start when there is no external power supply.
