Panasonic to mass produce long-life lithium-ion battery system for solar-powered homes in Europe

ntttttttttttt

Panasonic Corp said Monday that it will start mass production of a compact, secure and long-life lithium-ion battery system the company has developed for European homes. This marks the first time for the company to produce in volume such a system designed for Europe.

In Germany and other European countries, governments are cutting purchase prices for solar power in order to rein in the expansion of solar power generation, which led to increase in energy prices. The move is expected to create a growing need for a solution that allows consumers to optimize the self-consumption of solar energy generated on their rooftops.

Last year, Panasonic supplied its lithium-ion battery storage system for the S10 household energy storage system developed by E3/DC, an engineering firm in Germany. Through field tests in Germany, Panasonic is ready to mass produce the lithium-ion battery system.

The lithium-ion battery system consists of the Panasonic battery module with nominal capacity of 1.35kWh and a battery management system designed to control charge and discharge of the battery in accordance with customer needs. The battery system stores excess energy generated from the photovoltaic (PV) power system during peak hours of PV generation and discharges the energy as needed, providing an ideal solution as a household battery storage system that helps self-consumption of solar-generated power. It will also enable households to reduce the dependence on grid power and facilitate the further spread of green energy.
