## Guide

### 1. 5 MWh in a single 20 ft box

Meet the Envision Smart BESS ENS\-LC, a liquid\-cooled battery energy storage system that fits about 5 MWh into one standard 20\-foot container\. Drag the scene to walk around it\.

A two\-container ENS\-LC10060 is rated 10,060 kWh at 1,165 to 1,500 V\.

### 2. Factory\-built, ready to connect

Batteries, liquid cooling and fire protection arrive pre\-installed, which cuts work on site\. Open the six doors to see the battery racks inside, or tap a door pair\.

Envision says factory pre\-installation cuts balance\-of\-plant costs and site work\.

### 3. Cells made for storage

An IP67 pack slides out and comes apart: lid, busbars and battery management \(BMS\) wiring, rows of 315 Ah lithium iron phosphate \(LFP\) cells, and the liquid cold plate underneath\. Envision rates these cells for 12,000 cycles, over twice its first generation\.

One 315 Ah cell stores 1,008 Wh at 3\.2 V and measures 72 by 173 by 207 mm\. The pack's internal layout is illustrative\.

### 4. Liquid cooling from \-40 to \+50 °C

Coolant, shown in blue, runs from the cooling unit past every rack and through each pack's cold plate\. Its louvre opens to show the fans, condenser, compressor and pump that carry the heat away\.

Envision quotes an operating range of \-40 °C to \+50 °C for its liquid\-cooled systems\. The cooling unit's internals are a typical layout\.

### 5. Safety in layers

Smoke, heat and gas detectors watch every rack\. If a pack overheats, a clean\-agent cylinder releases through red piping to a nozzle at that sealed IP67 pack, and explosion\-proof vents clear gas through the roof\.

Exhaust ventilation and deflagration venting follow NFPA 69 and NFPA 68, and the enclosure carries a one\-hour fire rating\.

### 6. Grid\-ready power conversion

The power conversion system \(PCS\) links the batteries to the grid\. Its doors open on liquid\-cooled IGBT power modules in a three\-level design that reaches up to 99% efficiency and responds in 5 ms\. Switch modes to see which way the energy flows\.

The IP65 PCS can also run in grid\-forming mode\. Internal parts are illustrative\.

### 7. Why Envision

Envision designs its storage cells, battery systems and power conversion together and runs them with its EnOS software, drawing on more than 100 GW of its wind turbines installed worldwide\. Its batteries helped build Southeast Asia's largest storage plant\.

Sembcorp's Jurong Island plant in Singapore: 200 MW / 285 MWh, built with Envision and Huawei systems in six months in 2022\.
