URL More about NGK-Chugoku Electric
The Oki Hybrid Project introduced a hybrid storage battery system combining the NAS battery, with its excellent long-term output characteristics, and a lithium-ion battery, which has outstanding short-term output characteristics. The NAS battery will stabilize large, slow fluctuations, while the lithium-ion battery will absorb rapid, small fluctuations due to passing clouds or sudden changes in wind speed. The combination and coordinated control of two types of storage battery for a single objective is an advanced initiative being attempted for the first time in Japan.
