Introduction

Nichicon Corporation has delivered a quick charging station for EVs (Electric Vehicles) to the Katsura branch of the Kyoto Shinkin Bank. The carbon-free solar power generated by the system is stored and combined with power from the grid to charge EVs.
Besides charging EVs, the station also provides a portion of the electricity needed by the bank, and it ensures backup power in an emergency.
Nichicon has been developing power storage banks that link with utility grids in order to smooth out the significant fluctuations inherent in solar power and other natural energy sources. The company's technologies have so far earned it contracts to install charging and energy management systems in four locations in Kyoto Prefecture and one in Yamanashi Prefecture, as well as at the Suita Service Area of the Meishin Expressway in Osaka Prefecture. These installed facilities were made possible by integrating technologies that Nichicon has built up in the fields of battery management and power conditioning system.
This installation of an "energy-generation" and "energy-storage"-type quick charging station, the first for Nichicon at a private institution, marks the fruition of an agreement combining the Kyoto Shinkin Bank's forward thinking and Nichicon's advanced technologies.

 

Background of Development

With the environment a topic of increasing concern, efforts to reduce society's carbon emissions are in full swing worldwide. The automotive industry is placing particular focus on this issue as Japanese, North American, and European car manufacturers develop and mass-produce EVs. But EVs require large amounts of electricity to run, and rapidly charging them creates a strain on the power grid. To solve this problem, Nichicon has combined its quick charging stations with solar power generation and power storage technologies.

The greatest benefit of this "energy-generation" and "energy-storage"-type quick charging station is that it stores electricity generated by solar power and combines this stored power with electricity from the grid for the quick charging of EVs. This means there is no need to install expensive power supply equipment and so initial investment is kept to a minimum. And since the system contributes to peak load reduction of grid power, there's no change in electricity supply contracts and so running costs can be dramatically reduced.

The system can thus be set up without worrying about whether there is extra power to run it, a fact that opens up a range of possible installation locations. Whether installed at private companies, in expressway service areas, or in depopulated areas where gasoline stations are rapidly disappearing, Nichicon's quick charging systems can provide the infrastructure needed for the dissemination of EVs.

 

Main Features

  • Rapid charging of EVs using clean, renewable energy.
  • Electricity from solar power can also be used in buildings.
  • In case of emergencies such as blackouts, the buildings can use electricity stored in the lithium-ion battery, as well as that generated by the solar power system.
  • By storing electricity generated by solar power and combining it with electricity from the grid for the quick charging of EVs, customers get the most out of their electricity supply contracts and thus dramatically reduce running costs.
