Everything below comes from what CRRC Zhuzhou Institute publishes about the 5.X String-type 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-L5016AC-STR-0.5C — 5.016 MWh / 215 kW×12 | 5.016 MWh | 2.58 MW | 2 h |
| CESS-L5016AC-STR-0.25C — 5.016 MWh / 215 kW×6 | 5.016 MWh | 1.29 MW | 4 h |
