PCS
PCS Function: The PCS (Power Conversion System) is a bidirectional current-controllable
device that connects the energy storage battery system to the grid. Its main functions are
to facilitate energy exchange between the battery and the grid, and to control and
manage the charging and discharging of the battery. It enables bidirectional conversion
between DC and AC, allowing for both AC-to-DC conversion to charge the battery and
DC-to-AC conversion to supply power to loads or feed back to the grid.
PCS Model: The PCS used in this system is the EPCS105-AM model, which adopts a three-
level topology structure and has a rated output power of 105 kW

Fire protection systems
The system is equipped with an efficient and reliable fire suppression system that
automatically activates and extinguishes fires upon detection.
The product is equipped with a composite detector (incorporating smoke, temperature,
and gas detectors) and fire extinguishing agent on the top of the battery compartment.
Optionally, a water immersion sensor is installed at the bottom of the battery
compartment. When any of the three detectors in the composite detector detects an
anomaly, the system will stop operating and report the anomaly. If two detectors detect
anomalies, the fire extinguishing agent will be released to suppress the fire, and a
feedback signal will be sent to the EMS which can further relay the information to site
monitoring or the user. In the event of an anomaly detected by the water immersion
sensor, the system will also stop operating and report the anomaly.
The block diagram of the fire protection system is shown below:
