a new leader has emerged in the competition for large-scale energy storage systems. the haohan energy storage system announced by the chinese company byd directly competes with tesla's megapack and is currently being deployed in large-scale energy projects.
tesla recently launched the megapack 3, which has a capacity of 5mwh per container, an improvement over previous models. however, byd goes one step further. the standard configuration of haohan has a capacity of 14.5mwh, and the more compact version has a capacity of 10mwh.
this system is equipped with byd's proprietary 2710ah blade battery cells. with its high energy density, it can nearly halve the number of battery packs required for large-scale projects. it is estimated that this can reduce the overall cost of the project by 21.7%.
haohan was launched simultaneously with an inverter, the gc flux power electronics device, which supports an output range of 2.5mw to 10mw. it boasts an efficiency of up to 99.35%, can withstand three times overload for 10 seconds, and can adjust frequency and voltage in less than 100 milliseconds. the first project of this new system is a large-scale power station in saudi arabia with a capacity of 12.5gwh, which is equivalent to tesla's quarterly annual power generation capacity.
