Embodiments of the present application provide a starting method and a starting device. In an aspect, in the starting method provided by the embodiments of the present application, when an input voltage of an energy storage system meets a first specified condition, then judging whether the input voltage meets a second specified condition, if yes, then starting the energy storage system. Therefore, the technical solutions provided by the embodiments of the present application can solve the problems of poor starting efficiency and high cost in the prior art.

Starting method and starting device

Embodiments of the present application provide a method and device for identifying a master and slave battery packs. The method includes a first battery pack obtaining, after it is connected to a battery cabinet, its identifier, and obtaining identifiers of other battery packs in the battery cabinet through a communication bus. The total number of the battery packs is N, where N is a positive integer. The method may sort the identifiers of the first battery pack and of the other battery pack to obtain a sorted result. The method may identify the master battery pack and slave battery packs among the first battery pack and the other battery packs according to the sorted result. Each of the battery packs connected to a battery cabinet may automatically identify the master battery pack and slave battery packs according to their identifiers, eliminating manual configuration by a user, and improving configuration efficiency.

Method and device for identifying master and slave battery packs

The embodiments of the present disclosure provide a method for hot-plugging, a control device for hot-plugging, and a method and device for voltage balance. In one aspect, in an embodiment of the present disclosure, when there is a battery unit to be replaced in a plurality of parallel battery units, a branch in which the battery unit to be replaced locates may be cut off. Therefore, the technical solution provided by the embodiments of the present disclosure may solve a contradictory problem between the replacement of the battery unit and the normal operation of the power supply system in the related art and a problem caused thereby that the safety and stability of the power supply system are low.
