China-based rolling stock manufacturer CRRC has launched a 5 MWh battery storage system that uses liquid cooling for thermal management.
The world’s largest rolling stock manufacturer says that its new container storage system uses LFP cells with a 3.2 V/314 Ah capacity. The system also features a DC voltage range of 1,081.6 V to 1,497.6 V.
“The use of efficient thermal management technology enables the system to achieve an extreme temperature difference of 4 K and low power consumption in the entire temperature range,” a spokesperson from the company said. “From multi-stage physical isolation, quadruple fuse protection, strong and weak electricity zoning design, 4S-level fire management, Pack-level precise protection, real-time monitoring of cell-level health status, ms-level sampling, and extremely fast response, the energy storage system achieves ultimate safety.”
