GS Yuasa Corporation (Tokyo Stock Exchange: 6674) has received orders for a lithium-ion battery storage system ("the system") for the “CAINZ Urawa Misono Store”, a store operated by CAINZ CORPORATION. This system was subsidized by the Ministry of the Environment and has been in operation since March 2024.
The system, with a capacity of approximately 300kWh, will facilitate efficient utilization of solar power by storing surplus energy, generated at times, in lithium-ion batteries and then releasing the energy for use. It is also useful as a BCP measure in case of emergency.

The system is equipped with the “LEPS-2-14” lithium-ion battery for industrial use which is manufactured by GS Yuasa. The receipt of this order was secured as a result of a favorable evaluation of the quality, safety measures, and prompt after-sales service system of GS Yuasa products.

GS Yuasa will continue its contribution to the field of power supply stabilization and the stable operation of demand-side through expanding sales of its lithium-ion battery power storage systems. By helping to facilitate power grid adjustment capabilities, GS Yuasa is also contributing to further expansion of renewable energy use in support of Japan’s commitment to achieving carbon neutrality by 2050.

1. High level of safety ensured as voltage of all cells can be monitored and temperatures of all modules can be controlled
2. As the modules are fan-less, malfunctions are less likely to occur and the number of parts requiring replacement has been substantially reduced
3. Modules housed in fire prevention ordinance compliant cubicles in accordance with relevant laws and regulations
4. Able to withstand severely cold climatic conditions

Constant voltage monitoring and failure monitoring are performed on all of the cells to ensure the reliability of the entire system. In the event of a malfunction, GS Yuasa utilizes its nationwide service network (one of Japan’s largest) to promptly respond to customer needs.
