“Energy Generation and Storage” EV Charging System
for Disaster Relief Provides Renewable Energy to Roadside Station
in Obama City, Fukui Prefecture, Japan

Introduction

NICHICON CORPORATION is providing an “Energy Generation and Storage” EV charging system for disaster relief to the Wakasa Obama Roadside Station (i.e.highway rest area) in Fukui Prefecture, Japan. The system uses electricity from solar power to charge a storage unit and provide power to an EV charger.
Besides functioning as an environmentally friendly EV charger, this system can also use the electricity in the storage system to power lighting in the parking lot at night, and it can be used as an emergency power source during a blackout. This roadside station installation is the result of Nichicon technology that meets Obama City’s desire to provide the public with ‘green’ charging facilities and energy. This is the third system Nichicon has delivered to a roadside station in Fukui Prefecture, following successful installations in Takahama Town and Oi Town.

Background of Development

Ever since the Great East Japan Earthquake of March 2011, society has become increasingly aware of the compelling and pressing need to secure a stable supply of energy and to protect the environment. In particular, it has become crucial in times of emergency to ensure a stable supply of energy for public facilities designated as evacuation centers.
Nichicon has been focusing its business in the fields of environment and energy as it develops and brings to market products such as power storage systems, EV quick chargers, V2H (vehicle to home) systems, and various distributed power sources. Bringing together these many technologies and market successes, Nichicon has created a system centered around its power storage system and ultra-compact quick charger to bring to market the Energy Generation and Storage EV charging system for disaster relief for this roadside station in Fukui Prefecture. The company will continue to offer package power systems for disaster relief that make use of renewable energy, not only for roadside stations but also for facilities such as large supermarkets and schools.

Main Features

  • Energy Generation and Storage EV charging system for disaster relief combines a 3.5-kW solar power generator and a 30-kW quick charger.
  • Large-capacity 7.2-kWh storage battery can be charged with solar power in the daytime and used at night to run the LED lighting (approximately 700W) in the parking lot.
  • The system offers peace of mind in case of blackouts due to natural and other disasters since it can be used to run the parking lot lighting at night.
