Mass production of Lithium-ion battery
system from Panasonic for home energy storage
Panasonic Corporation has announced that it will start
mass production of lithium-ion battery system in June. This
secure system was developed for European homes and is the
first time for the company to produce in volume such a system
designed for Europe. This move is to strengthen the company's
storage battery business in Germany and other European countries.
As the governments are cutting prices for solar power, the
consumers are allowed 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 a suitable 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.
1. The lithium-ion battery system has design life time of
5000 cycles and realizes long-term operation.
2. The battery management provides battery status information
to the controller of home energy storage system,
which allows users to remotely monitor the status of the
system and battery.
3. A high capacity and high voltage lithium-ion battery
system employs a lithium-ion cell that is specifically
developed for an energy storage application.
"In Germany, there is a concern that the integration
of renewable energy sources, such as wind and solar power,
into the power grid could cause instability in power distribution
because of their unpredictable nature," said Mr. Fumitoshi
Terashima, director, smart energy systems business unit,
Energy Company of Panasonic.
"With our state-of-art lithium-ion battery technology
and high-quality battery management systems, we will promote
self-consumption of solar power generated by households
as well as reduction of load during peak hours. In so doing,
Panasonic aims for a leading position in providing a solution
to protect the power grid system."
In Europe, the lithium-ion battery system is distributed
by Smart Energy Systems Department, Mobile Energy Business
Division of SANYO Component Europe GmbH.
