Energy Storage Stations

Chemical energy storage is one of the important means to solve the intermittent volatility of new energy wind power and photovoltaic, and realize the function of peak-trimming, and has gradually received attention as an emerging application scenario. Lithium-ion battery energy storage is the most feasible technical route at present, which has the advantages of high energy density, small self-discharge, no memory effect, wide operating temperature range, rapid charge and discharge, long service life, no environmental pollution, etc., but lithium metal is the most active metal among known elements (including radioactive elements), and its thermal runaway phenomenon occurs from time to time. It has buried a safety hazard for the application of lithium batteries in energy storage, especially because it is difficult to inhibit the reignition of lithium batteries after thermal runaway fire, its fire safety has become one of the biggest difficulties in the industry. The fire probability of global commercial energy storage power stations has reached 1.52%,  as the last passive defense system, reasonable design, material selection, layout and construction directly affect the healthy development of the energy storage industry.

In view of the fire safety hazards and fire suppression difficulties of energy storage systems, Orena has launched a fire safety solution specifically for the energy storage industry on the basis of full research and testing and combined with fire standards. Based on the principle of "early detection, early discovery, early alarm, early disposal", it advocates timely warning, rapid alarm and accurate suppression of the primary stage of thermal runaway of lithium batteries in the energy storage cabin. In the case of fire suppression, the loss caused by fire should be reduced as much as possible.

The energy storage fire fighting system is mainly composed of the detection and control part and the fire fighting part. Orena has the right fire de­tect­ors for different levels from pack, cluster, cabinet and station which can realize early fire warning, multi-type fire detection, visual video remote alarm, and starting fire extinguishing device immediately.

• Visual alarm through 2-wire fire signal loop circuit, quickly confirm fire alarm, quickly extinguish fire, no fear of false alarms, avoid false spray.

• The visual fire detector is equipped with a built-in camera, integrating security and fire protection.

• A small size aspirating high-sensitivity fire detector is installed in the cluster battery cabinet, providing an extremely early warning and visual confirmation of fire alarms.

• Metal smoke hoods and duct smoke detectors are installed in the areas with high wind speed within the cabin. 

• Combine local control and remote control
• Construct a closed-loop fire control system featuring high reliability, high anti-interference, multi-dimensional detection, early warning, timely confirmation of fire alarms, and rapid fire extinguishing.
