Description
215 kWh Liquid-Cooled C&I Energy Storage Container is a 215 kWh lithium iron phosphate energy storage platform rated 100 kW for commercial and industrial applications. The 215 kWh liquid-cooled container is the standard mid-size C&I unit, combining 280 Ah cells, a 768 V DC bus and integrated thermal management in a 10-foot footprint. It is configured for grid-tied, behind-the-meter or hybrid operation.
Cells, Modules & BMS
The system is built from 280 Ah prismatic LiFePO4 cells in 1P240S modules with a three-level (BMU / BCU / BAU) BMS architecture. Protection covers cell and module over-voltage, under-voltage, over-current, over-temperature, insulation fault and short circuit. Communication uses CAN / RS485 / Ethernet (Modbus TCP, IEC 61850 optional) for EMS, SCADA and cloud platform integration.
Thermal Management & Safety
Liquid cooling circulates coolant through cold plates between modules, holding cell temperature difference below 3C and extending cell life in hot climates. Multi-level fire protection is provided by perfluorohexanone or aerosol suppression with gas, smoke and temperature detection, plus pressure relief. The enclosure is rated IP54.
Cycle Life & Performance
Cells are specified for more than 6,000 cycles at 80% depth of discharge, with a usable SOC window of 5% – 95% and round-trip efficiency of 89% – 91% (DC round-trip, 0.5C). Liquid cooling keeps capacity fade uniform across modules, so usable capacity is retained longer than in air-cooled designs above 35C ambient. Ambient operating range is -20 °C to +60 °C, with derating above 45C where required.
Charging & Grid Interface
DC nominal voltage is 768 V (240S) with a maximum continuous charge and discharge rate of 0.5C. Supplied with a 100 kW PCS in the same enclosure for AC-coupled operation, or as a DC block for pairing with an external 100-125 kW PCS. Operating modes include peak shaving, demand charge management, solar self-consumption and diesel generator support, scheduled through the EMS.
Mechanical & Installation
The unit is supplied as a 10-foot containerised unit measuring 2991 × 2438 × 2591 mm. The container is delivered with lifting points, base cable entries and pre-installed fire and thermal management systems. Commissioning follows the supplied installation manual, with remote support available.
Deployment Scenarios
Deployed at industrial parks, commercial complexes, hotels and hospitals for daily two-cycle peak shaving, at solar-plus-storage plants behind the meter, and at diesel generator sites seeking fuel savings.
Customisation
Capacity, PCS rating, AC or DC coupling, protocol mapping and branding can be specified per project, and cabinet or container layouts can be adapted to site constraints. Larger capacities than the standard range are available on a project basis.
Factory battery module range
Storage systems are built from the following battery modules, with the system capacity configured per project:
| Model | Chemistry | Nominal voltage | Nominal capacity |
|---|---|---|---|
| YD-48-100 | LiFePO4 | 51.2 V | 100 Ah |
| YD-48-200 | LiFePO4 | 51.2 V | 200 Ah |
| YD-48-280 | LiFePO4 | 51.2 V | 280 Ah |
| YD-48-314 | LiFePO4 | 51.2 V | 314 Ah |
| YD-48-942 | LiFePO4 | 51.2 V | 942 Ah |
Other models are customised: storage cabinets from 5–200 kWh, and commercial and industrial storage from 200–5000 kWh.
The liquid-cooled outdoor cabinet we build for commercial and industrial projects integrates the battery system, battery management system, conversion system, thermal management system and fire protection system in one cabinet.
Project-level configurations include “wind–solar–storage–DC–flexible” building energy systems (PV generation plus storage, DC distribution and flexible interaction) and integrated PV-plus-storage charging stations for shared e-mobility fleets.
Each system is factory-tested for capacity, insulation, communication and protection functions. Compliance target standards: UN38.3, IEC 62619, IEC 62933, CE and RoHS. Warranty: 5 years, extendable to 8 years.
