1 Pangunehang Teknikal na Arkitektura ng C&I BESS​
​1.1 All-in-One Integrated Design​
Ang modernong Commercial & Industrial Battery Energy Storage Systems (BESS) ay gumagamit ng isang napakaintegradong arkitektura, na naglalakip ng battery packs, bidirectional power conversion systems (PCS), energy management systems (EMS), thermal management, at fire suppression systems sa loob ng iisang cabinet o container. Ang disenyo na ito ay nagsasanggalang na mabawasan ang interconnection wiring, taas ang sistema ng energy conversion efficiency hanggang 95%-97%, at malaking pagbabawas sa installation complexity at footprint. Halimbawa, ang serye ng Greensoul GSL-BESS ay gumagamit ng modular design na sumusuporta sa capacity expansion mula 30kWh hanggang 180kWh. Ang bawat battery pack ay may independent na Battery Management System (BMS) na nagbibigay ng real-time status monitoring at flexible capacity upgrades, na nasasapat sa dual requirements ng space utilization at investment flexibility para sa mga C&I users.

​1.2 Intelligent Thermal Management​
Ang teknolohiya ng thermal management ay isang core element na nag-uugnay sa seguridad at lifespan ng BESS. Ang modernong mga sistema ay gumagamit ng differentiated thermal control strategies para sa iba't ibang application scenarios:

• ​Liquid Cooling Technology:​​ Inilapat sa high-power scenarios (hal. Mennete ESS-C-JG261-L system), ang coolant circulation ay nag-aasikaso na ang battery pack temperature differentials ≤5°C. Kumpara sa traditional air-cooling, ang heat dissipation efficiency ay tumaas ng 40%, na siyang partikular na suitable para sa high-temperature, high-dust industrial environments. Ang IP54 protection rating nito ay nag-uugnay sa stable operation under harsh conditions.
• ​Intelligent Air-Cooling System:​​ Para sa small/medium C&I scenarios (hal. ESS-C-JG229-F), multi-stage fan speed adjustment at zonal temperature control, kasama ang environmental humidity adaptive algorithms, ay optimizes annual energy efficiency sa pamamagitan ng asikasong heat dissipation habang nagbabawas ng auxiliary power consumption.

​1.3 Multi-Layered Safety Protection​
Ang C&I BESS ay naglalaman ng multi-tiered safety protection system:

• ​Cell-Level Protection:​​ Gumagamit ng lithium iron phosphate (LFP) batteries na may superior thermal stability. Ang kanilang thermal runaway onset temperature ay mas mataas kaysa NCM batteries, na siyang nagbabawas ng fire at explosion risks.
• ​Pack-Level Fire Suppression:​​ Nakakabit ng perfluorohexanone o aerosol fire extinguishing agents. Ang temperature-smoke-gas composite detectors ay nagbibigay ng millisecond-level response, na nag-aasikaso sa localized suppression bago magkaroon ng thermal runaway propagation.
• ​System-Level Protection:​​ Naglalaman ng arc fault detection at insulation monitoring, kasama ang grid anti-islanding protection mechanisms (compliant with GB/T 34120 standard), na nag-uugnay sa grid connection safety.

​1.4 Efficient Energy Management​
Ang "Smart Brain" ng BESS - ang EMS system ay maximaizes ang energy value sa pamamagitan ng multi-strategy collaborative optimization:

• ​Dynamic Electricity Pricing Strategy:​​ Nagcharge sa off-peak periods (typical ¥0.3-0.4/kWh) at nagdischarge sa peak periods (¥1.0-1.5/kWh), na nag-aasikaso sa fundamental peak-valley arbitrage.
• ​Demand Charge Management:​​ Nagsmooth ng 15-minute peak demand power sa pamamagitan ng load forecasting algorithms, nagbabawas ng basic electricity costs (cutting enterprise electricity bills by 15%-30%).
• ​PV-Storage Coordination:​​ Dynamically adjusts the ratio between PV generation and battery charge/discharge, increasing the self-consumption rate to over 80%.
