We developed a lithium-ion mega battery system with one of the world's largest capacities by installing approximately 1,000 units of 1.6kWh Standard Battery Systems for Power Storage in the power storage building and the administration building of the Kasai Green Energy Park.
In the power storage building, economical late-night power is mainly used to charge batteries, which is then consumed during the day, while in the administration building, unconverted DC electricity from photovoltaic modules is the main source of power for charging batteries and direct consumption.
The Standard Battery System for Power Storage is a storage battery unit with a capacity of approximately 1.6kWh, containing 312 cylindrical lithium-ion battery cells (18650 size: 18mm in diameter, 65mm in length) often used in laptop PCs. Multiple systems can be connected to provide larger capacity.
* As of October 2010, as a storage battery system using consumer use lithium-ion batteries. Based on SANYO's study.
