The stationary energy storage system project combines renewable energy, end-of-life batteries and electric vehicles to demonstrate the technology as Japan moves to a low carbonized power economy.
The project will use 10 Nissan e-NV200 electric commercial vehicles and EV batteries to stabilize output from the rooftop solar panel system and for peak-shifting services to reduce the plant’s electricity costs.
Nissan employees will use the e-NV200s for commuting or work purposes, with the vehicle’s batteries recycled and refabricated into components of the ESS at their end-of life.
The two companies co-developed the system for use in virtual power plants that are expected to be operating in Japan by 2020.
They have already field tested ESSs and EVs as part of their participation in the Kansai VPP project, which will be used to optimize to manage supply and demand throughout the region.
Last December ESJB reported how California-based firms Stem and Sunverge are due to install systems across multiple sites in Japan to examine how VPPs could allow the country to increase renewables into its energy mix.
In January Nissan Motor, Kansai Electric Power, and Sumitomo Electric Industries started testing tools to charge EVs via remote control as part of the Kansai VPP Project.
Sixty electric and plug-in hybrid vehicles owned by customers and Kansai will be outfitted with EV switches, which are control instruments for EV charging developed in conjunction with Sumitomo.
All three firms will link their servers to enable remote-control charging, collect vehicle data and identify available charging capacity.
