Thereafter, the updated network data is transmitted to an upper controller (e.g., a power conversion device or an inverter of an energy storage system) in the network that requested the data (S342).
- an upper controller e.g., a power conversion device or an inverter of an energy storage system
- the data tasks (S310, S320) and the periodic network task (S340) illustrated in Fig. 3 can be performed repeatedly at regular intervals.

- a command from a network task that is performed periodically for example, a 1-second update command in FIG. 4.
- network data for each protocol is updated, and the updated data can be transmitted to the upper controller through the xxx_send_data function.
- the battery management device in addition to the network tasks that are performed periodically, when a read/write request for BMS data is received from the inverter through an external communication port (i.e., when an interrupt occurs), the battery management device must immediately return the requested data. To this end, the battery management device registers the inverter's BMS data request in the form of an event, and when a pre-registered event occurs, calls an event handler function to process the event, thereby synchronizing the current BMS data with the network data.
- the order of operations can be determined by considering the task priority.
- the event handler is processed by the control task, and since the control task has a higher priority than the network task, the protocol update called by the event handler is performed before the periodic update operation. Accordingly, the protocol update is performed by the control task, and the update sequence by the network task is not performed to prevent duplication.
