Name

Description

1

Audible and Visual Fire Alarms

In the event of a fire hazard, the battery cabinet activates the thermal suppression device and sounds an alarm. See 6.4 Thermal Suppression System for details.

2

Heat and Smoke Detector

Smoke detection triggers an alarm, while heat detection activates an alarm and the thermal suppression system.

3

Passive Deflagration Vent

Explosion control vents relieve pressure during thermal events by venting gases, which helps minimize the risk of explosion.

4

Thermal Management System (TMS)

The TMS manages heating and cooling for the battery cabinet. See Section 6.3 for more information.

5

Battery Packs

Energy storage units with integrated cell monitoring via the Battery Management Unit (BMU). Each pack features an aerosol fire suppression system and aerogel-based cell separation, ensuring advanced thermal runaway mitigation.

6

High Voltage Box (HV Box)

The HV Box manages power flow, protects the system, provides redundant control via UPS, and monitors the system through the Battery Control Unit (BCU). For information on the High-Voltage Battery box, see Section 6.1.

7

Manual Service Disconnect (MSD)

Each battery pack is equipped with a Manual Service Disconnect (MSD).

8

Dehumidifier

The humidifier maintains humidity inside the sealed battery cabinet at an acceptable level.

9

Cabinet Aerosol Fire Suppression Device

If a high heat event is detected, the aerosol fire suppression system is automatically activated to quickly release an aerosol fire suppression agent.

10

LYNK II Gateway

The LYNK II Gateway facilitates communication between the battery cabinet BCU and external devices, such as inverters or cloud-based systems.

11

LED Indicators

The LEDs indicate the system operation status:

  • Green (solid): Battery On, DC Contacts Closed (in operation)

  • Green (flashing): Battery On, DC Contacts Open (standby)

  • Amber: Warning Alarm or Critical Fault

  • Red: E-Stop is Engaged.

12

E-Stop

Emergency stop switch for manual shutdown of the battery cabinet.
