Energy storage developer Powin Energy Corporation has been awarded a Chinese patent for its battery management system.
Designed specifically for energy storage systems, the US firm’s Battery Pack Operating System (bp-OS), was also awarded a US patent in June.
The Certificate of Invention Patent was issued by the State Intellectual Property Office of the People’s Republic of China.
The bp-OS reduces the number of DC connectors and other components required to transfer energy using BMS software designed for electric vehicles.
This allows more batteries to be connected onto a single string and potentially reduce the number of transformers, inverters, and electrical work on a project.
Instead of working to maintain a balance across an entire array of batteries, the bp-OS balances individual cells to an optimised level by connecting individual battery pack to the network to keep the delta V between the highest and lowest cells to a max of 10 millivolts.
