PV Tech and Sungrow are co-hosting a webinar exploring how liquid-cooled battery power storage methods can enhance challenge economics and prolong tools life. To register for the webinar, which takes place on 22 November at 3pm GMT, click here.
Product define
Sungrow has launched its latest ST2752UX liquid-cooled battery power storage methods (BESSs), that includes an AC/DC coupling answer for utility-scale energy crops, and the ST500CP-250HV for world business and industrial (C&I) functions.
The brand new methods supply minimised system price, greater dischargeable power capability and larger flexibility.
Downside
With industries all over the world starting to recuperate from the affect of COVID, the demand for power has elevated considerably, creating imbalance between provide and demand. Renewable power is seen as a long-term answer, and together with power storage will help resolve problems with volatility in provide.
Nonetheless, whereas power storage is a quickly rising market in lots of components of the world, giant utility-scale battery storage crops face quite a few challenges together with excessive capital price, low power output, low flexibility and issues of safety.
Up to now, the overwhelming majority of battery storage methods have used HVAC for air cooling, and direct paralleling of a number of battery racks to extend power density. This may result in issues equivalent to excessive auxiliary energy consumption and low warmth dissipation effectivity, having a unfavorable impact on challenge revenue.
Resolution
Sungrow’s ST2752UX and ST500CP-250HV BESS options use superior liquid cooling know-how to dissipate warmth extra evenly from the battery, with the improved thermal conductivity of the coolant lowering the auxiliary energy consumption required for system cooling.
Utility
ST2752UX liquid-cooled battery cupboard has a most capability 2,752kWh, with a liquid cooling unit, 48 battery modules (64 cells per module), 4 DC/DC (0.25C, 4 hours) or 8 DC/DC (0.5C, 2 hours), with extra firefighting functionality. In line with buyer necessities, the overall power capability of every battery cupboard could be tailor-made to realize one of the best economics for a particular challenge.
ST500CP-250HV C&I answer has a most capability of 535kWh, together with a liquid cooling unit, 20 battery modules (60 batteries per module), switchgear, hearth safety system and PCS cupboard of 250kW.
Platform
Energy crops and C&I functions.
Availability
Already out there in Europe.
