Full-Link Safety Protection Guide for Energy Storage Stations

As the energy storage industry enters a period of rapid development, overlapping risks such as battery thermal runaway, electrical fires, and perimeter intrusion pose severe challenges to the safe operation of energy storage stations. With the growing global focus on safety and compliance in the energy storage sector, construction and operation and maintenance units shall strengthen the operation management of energy storage stations. They may leverage digital technologies such as big data and cloud computing to achieve the perception, diagnosis, and early warning of energy storage safety status, thereby improving the level of intelligent operation and maintenance and safety prevention and control of the stations.

An energy storage system generally includes a battery energy storage unit, a grid connection system, an environmental control unit, an alarm system, etc. The main potential safety hazards include:

· Fires: Electrical fires (e.g., transformer fires, cable fires) and Battery-induced fires (e.g., exposure to open flames, collisions, overcharging and over-discharging during charging and discharging processes; electrolyte temperature rise, etc.).

· Explosions: Hydrogen gas generated by storage batteries during charging and discharging may cause explosions if indoor ventilation is poor and external open flames or collisions occur; internal faults of pad-mounted transformers may trigger arc heating, leading to potential combustion and explosions.

1. Real-Time Monitoring Inside Containerized Energy Storage Stations

1) 24/7 Precise Temperature Measurement

Non-contact precise temperature measurement enables monitoring the temperature distribution inside containerized stations, achieving 24/7 real-time online temperature monitoring of the station status. The FC435T/FC465T Dual-Spectrum Bullet Camera offers infrared HD resolution options of 384×288/640×512, covering a temperature measurement range of -20℃~550℃, which can accurately monitor temperature changes of equipment such as transformers and cable joints to avoid electrical fire risks. For special scenarios such as high and low temperature explosion-proof temperature chambers, the FC125T Dual-Spectrum Turret Camera adopts ceiling-mounted installation, with 3.2/7mm lenses to achieve full-scene coverage without exposing cables, ensuring 24/7 monitoring of battery sample status.

2) Multi-Area Temperature Measurement

During operation, the system supports multi-area temperature measurement for heat-prone parts of equipment such as battery packs, converters, cables, and power distribution devices. Users can flexibly draw multiple temperature measurement areas to focus on monitoring key parts.

3) Over-Temperature Automatic Early Warning

Equipped with a built-in AI algorithm for over-temperature diagnosis, it can automatically track the maximum and minimum temperatures in the monitoring screen and trigger automatic alarms when over-temperature occurs. It intelligently links image capture + video recording and outputs alarm information.

2. Early Fire and Smoke Warning: Nip Fires in the Bud

Most fires in energy storage stations originate from the smoldering stage of battery thermal runaway, which is difficult to detect early by traditional smoke detectors. However, infrared thermal imaging technology can capture abnormalities during the heat accumulation stage before a fire breaks out. The PD225T Dual-Spectrum Speed Dome Camera is equipped with an AI fire point detection algorithm, which can penetrate smoke to accurately locate fire sources. Its dual-spectrum fusion design of 256×192 thermal imaging and 5MP visible light ensures stable operation day and night. When abnormal temperatures or fire points are detected, the equipment immediately links with audible and visual alarms, fire-fighting devices, and refrigeration systems to form an “early warning-disposal” closed loop. It detects potential hazards hours earlier than traditional monitoring methods, effectively curbing the spread of fires. Meanwhile, the system supports intelligent behavior analysis, which can distinguish between normal heat sources and fire hotspots, filter interference signals such as sunlight reflection and equipment heat dissipation, reduce false alarm rates, and ensure the accuracy of early warnings.

3. Perimeter Security: 24/7 Uninterrupted Full-Area Protection

Most energy storage stations are located outdoors, and human-induced risks such as perimeter intrusion and illegal operations cannot be ignored. Raythink adopts multi-form equipment including pan-tilt cameras, speed dome cameras, and bullet cameras to implement 360° full-scene autonomous cruising monitoring. It achieves full-scene perimeter and key area sealing and control of energy storage stations, ensuring that issues such as unauthorized intrusion, fire detection, and station environment safety are detected in the first place. This realizes intelligent supervision of energy storage stations and reduces the labor cost of manual inspections.
