Storage Batteries

Storage batteries reduce output fluctuations of natural energy and are used as a power source for vehicles and railroad vehicles. They play an important role in achieving a low-carbon society.

Contributing to solving environmental issues

Our storage batteries reduce and stabilize output fluctuations in photovoltaic generation and wind power generation

Although natural energy is effective for the reduction of CO2 emissions, there is an issue in that output fluctuates depending on the weather. Storage batteries compensate for the output fluctuations and play an important role in achieving a stable energy supply.

Contributing to the promotion of fuel-efficient and low-carbon vehicles

Potential future storage battery introduction

Key Environmental Technologies

Hitachi provides industrial and automotive lead storage batteries that play an important role in energy management in terms of energy storage and output control.

Stationary VRLA*2 batteries for power storage "LL Series"

By using a technology that improves corrosion resistance, the number of charge-discharge cycles has been prolonged about 100 times*3 in the storage battery for a system that reduces output fluctuations of renewable energy, and resource savings have been achieved.
