FusionSolar Smart String ESS Solution: Multi-Level Active Protection for Ultimate Safety

An power storage system (ESS) shouldn’t be solely batteries however a complete system that mixes electrochemical, energy electronics, digital, and thermal applied sciences. Because the penetration of renewable power continues to extend, we’re seeing an explosive progress within the power storage market. With this growth, security has grow to be an necessary subject within the business.

ESS performs an necessary function in new power programs, which is driving the speedy progress of the market worldwide. Wooden Mackenzie’s report exhibits that international power storage capability can develop at a compound annual progress fee (CAGR) of 31%, recording 741 gigawatt-hours (GWh) of cumulative capability in 2030. As such, occasional accidents security continues in battery power storage vegetation, placing personnel in danger and inflicting severe financial losses.

Lithium batteries are the core part of a battery power storage system (BESS). Inside and exterior sources can rapidly elevate the temperature of battery cells, resulting in thermal runaway. It could possibly launch flammable and explosive gases, inflicting fires and even explosions. Usually, there are a number of points that may result in security accidents in lithium BESSs:

Manufacturing defects, quick circuits on account of lithium plating, and battery cell instability
Circulating currents between lithium battery racks, which accelerates battery cell degradation
Exterior quick circuits on account of insulation failures, inner quick circuits on account of irregular present and overheating
Modifications within the exterior atmosphere, reminiscent of excessive temperature and excessive humidity, speed up the growing old of the lithium battery and trigger insulation failure and quick circuits, leading to warmth conduction.
Battery monitoring failure on account of improper configuration and coordination, or incomplete data sharing between the Battery Administration System (BMS), Power Administration System (EMS), and Energy Conversion System (PCS)

To make sure the protection of your entire ESS, it requires subtle monitoring and administration of batteries not solely from the system stage, but additionally from the rack stage, the pack stage, and even the cell stage. By leveraging many years of in depth R&D funding and sensible software of electrochemical, energy electronics and digital applied sciences, FusionSolar pioneered the Good String ESS Answer with revolutionary battery packs and rack stage optimization, in addition to multi-level security safety with refined monitoring and administration of ESS cost/discharge, reaching increased battery capability and elevated security.

The FusionSolar Good String ESS Answer adopts a multi-level security design for final safety.

Structural Security
The answer design separates batteries, rack-level optimizers, and fireplace management cabins to make sure strong, steady fireplace monitoring and safety. The safety ranking of the entire system reaches IP55, the anti-corrosion stage of the container is C5, and the system can face up to earthquakes as much as magnitude 9.

Electrical Security
4-level lively management and two-level bodily isolation present complete overcurrent safety —— when overcurrent is detected, the system will set off the BMS to restrict the present of the battery packs and rack from on the software program facet. If the error will get too huge, the battery pack and rack optimizers shut down the system from the {hardware} facet (‘four-level’). Lastly, circuit breakers and fuses assist stop fault propagation from the system stage (‘two ranges’). As well as, if the ESS shouldn’t be operating, for instance, throughout transportation or set up, the voltage on the terminals of the battery pack is zero, which helps shield development and O&M personnel from accidents.

Fireplace Security
The FusionSolar Good String ESS Answer has a number of temperature, humidity, and smoke sensors. These are the explanations for warning the atmosphere round. For instance, in the event that they detect flammable gasoline, the sensors robotically shut off the gasoline to forestall fires and explosions. After the exhaust system is turned off, instantly launch an extinguisher to extinguish the hearth and forestall the accident from escalating.

The AI-based BMS Clever Alarm
The answer makes use of a brand new patented AI-based short-circuit algorithm, which intelligently detects inner short-circuit on the battery cell stage, enabling early detection, early warning, and multi-level linkage safety.

Security is at all times a high precedence and is essential as we give attention to carbon neutrality. FusionSolar is dedicated to offering safer and extra dependable ESS options by persevering with to extend funding in R&D and buying wealthy expertise in energy electronics, thermal, AI, and digital applied sciences, and also will proceed to work with prospects and business companions to speed up carbon neutrality for a greener future.
