Everything below comes from what CRRC Zhuzhou Institute publishes about the 3.X Liquid Cooling Energy Storage System: the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
| Variants | Energy | Power | Duration |
|---|---|---|---|
| CESS-L3727-EU/US-0.5C — 3.727 MWh + 1725 kW×2 | 3.727 MWh | 3.45 MW | 2 h |
| CESS-L3440-EU-1C — 3.44 MWh + 1725 kW×2 | 3.44 MWh | 3.45 MW | 1 h |
