Smart Grid (2): Nissan/Mitsubishi developing dischargeable EVs

Plan to use batteries recycled from EVs as stationary storage devices in homes and elsewhere



 Having an electric storage capacity in workplaces and homes is an important step in building a smart grid. This is why a number of attempts are being made such as building homes with storage capacity and draining electricity from batteries on EVs and PHEVs and using them as storage batteries for home use (referred to as "dischargeable EVs" or "V2H (Vehicle to Home)" in this report.

 The previous report "Smart Grid (1)" of April 14 reported plans by Toyota Group's homebuilding companies to provide homes with electric storage capacities and the demonstration experiments being conducted in the city of Toyota since 2010 focusing on the verification of "V2H" by Toyota to use the storage batteries in EVs and PHEVs as the electric suppliers.

 This report, Smart Grid (2), contains reports on the "dischargeable EVs" being pursued by Nissan and Mitsubishi Motors, and their plans to construct related systems.

 It is known that the lithium-ion batteries, after being removed from EVs, can be reused as stationary storage batteries in homes and elsewhere with the likely result of lowering the initial battery cost affecting the EV sales. This possibility is being studied by Nissan and Sumitomo Corporation, Mitsubishi Motors, Itochu Corporation and other companies.

 Also reported here are special efforts being made to build systems that include charging systems and car sharing systems that will encourage market penetration of EVs and PHEVs.

 Honda began a demonstration program in December 2010 in Japan and the US with the Fit EV and the Inspire-based PHEV.

Nissan: Planning a second-life business for EV batteries

 Nissan will conduct a demonstration experiment in the city of Kitakyushu regarding the reuse of batteries.

 In September 2010, Nissan and Sumitomo Corporation formed a new joint-venture company, 4R Energy, to conduct research on the second-life business for lithium-ion batteries removed permanently from EVs. A group consisting of Asahi Kasei Corporation, Nissan, and Omron and Sumitomo Forestry will construct storage systems for homes using recycled batteries removed from the Nissan Leaf EVs that will be supplied by 4R Energy.

 It is said that the lithium-ion batteries removed from EVs can be used for home use for around 20 years.

Nissan: Conducting demonstration experiments in the city of Kitakyushu regarding the second-life business for batteries

 Nissan will conduct a demonstration experiment in the city of Kitakyushu regarding the secondary use of lithium-ion batteries removed from EVs. Nissan will select homes, buildings and public facilities, during 2010 to 2011, which will benefit from the secondary use of the recycled batteries. After making necessary adjustments with those concerned, Nissan will start experiments in 2012 and verify the results. The company intends to reduce the price of EVs by reusing the batteries to promote market penetration of EVs.

Second-life use of batteries from the Nissan Leaf EV as storage batteries for homes
Asahi Kasei,
Nissan, Omron
 Asahi Kasei, Nissan and Omron will develop systems for secondary use of EV batteries in-home applications. Their idea is to construct a new system to reuse the lithium-ion batteries, removed from the steadily growing number of EVs, to store excess electricity from power companies during night hours at lower rates, or store electricity produced by photovoltaic generation in homes.
 Initially, Asahi Kasei will use new lithium-ion batteries to build an electric storage system and sell it to consumers through Asahi Kasei Homes Corporation in FY2012 at one to two million yen at first. The company plans to lower the price to roughly half a million yen by switching to recycled batteries in phases that will be procured from 4R Energy (after replacing deteriorated parts). Their trial calculations show that the system will lead to saving monthly electricity bills by about 3,000 yen per average household if all its electric demand is met by electricity stored at discounted night-time rates.
 Omron will develop equipment that will convert the direct current stored in batteries to alternate current for home use and that is used to manage and control charge and discharge conditions.
Sumitomo Forestry  In February 2011, Sumitomo Forestry invited 13 home owners to monitor storage batteries originally intended for use on the Nissan Leaf EVs and redesigned for home use. New batteries will be used at first until recycled ones become available for reuse after demonstration experiments with 4R Energy is completed.
 The invitation is limited to those who have purchased Sumitomo Forestry's homes equipped with solar systems. The battery system (storage capacity of 12kWh, one half that of the Leaf EV) and Toshiba's home IT system will be provided and installed free of charge for those monitors that agree to provide data continuously for five years.

Mitsubishi Motors: Developing dischargeable EVs and technologies for secondary use of EV batteries

 Mitsubishi Motors, Mitsubishi Heavy Industries and Renesas Electronics Corporation will participate in Kyoto Prefecture's Keihanna Eco-city next-generation energy and social system demonstration project (one of the four areas selected by the Ministry of Economy, Trade and Industry) aspiring to develop dischargeable EV technologies.

 In December 2010, Mitsubishi Motors, Mitsubishi Electric Corporation and Mitsubishi Corporation took on a new initiative aimed at the optimization of energy management using a photovoltaic power generation system, EVs and storage batteries removed from EVs, all placed in Mitsubishi Motors' Nagoya Plant.

 In January 2011, Mitsubishi Motors and three other companies began demonstration experiments in Kyoto Prefecture regarding secondary use of batteries (LEV50) originally made for the i-MiEV.

Mitsubishi Motors and others: Verifying secondary use of EV batteries at Nagoya Plant

 In December 2010, Mitsubishi Motors, Mitsubishi Electric Corporation and Mitsubishi Corporation installed a photovoltaic power generation system, EVs with batteries and batteries removed from EVs for reuse purposes. The batteries will be recharged using photovoltaics among other sources, and discharged as needed. This marks the start of development and verification of the EMS (Energy Management System) that will contribute to the optimization of energy balance at the plant.
Mitsubishi Motors and others: Developing technologies to optimize charge and discharge of batteries on board EVs
 In addition, the three companies will develop EIS (Electric Vehicle Integration System), technologies intending to set optimal charge and discharge of the storage batteries on the EV so that they may be used as an external power source without placing a burden on the electric vehicle.

(Note) This project has been accepted under the "technical development of power storage combined systems" project by NEDO that will bear two thirds of the project's R&D costs.

Mitsubishi Motors, GS Yuasa, etc.: Demonstration experiments started for secondary use of EV batteries

 In June 2010, Mitsubishi Motors, GS Yuasa, Mitsubishi Corporation and Lithium Energy Japan announced that the lithium-ion batteries "LEV50" used on the Mitsubishi i-MiEV can be kept for second-life use, after they are removed from the EV, for storing natural and other energies. In January 2011, the four companies began a demonstration experiment in the city of Kyoto to develop second-life business for lithium-ion batteries.
 The experiment will use the PV-EV system developed by GS Yuasa (PV stands for "photovoltaic" more commonly known as solar power generation; the PV-EV is a system designed to store electricity produced by solar cells in the lithium-ion batteries and quick-charge the EV using the stored electricity.) The system will use lithium-ion batteries "LEV50" used on and removed from the Mitsubishi i-MiEV to minimize the system costs while exploring a broad range of second-life usages for the "LEV50" batteries.
 The solar cells will be laid atop the Lawson convenience stores in Kyoto and excess electricity will be used for the store lighting. The system represents the highly-efficient use of electricity: direct current is used along the entire process from generation by the solar cells, storage and charging of the EV.

(Notes) 1. In December 2010, the Ministry of Economy, Trade and Industry, and the Ministry of Land, Infrastructure, Transport and Tourism announced their judgment that EV charging business fell outside of business regulations imposed by the Electricity Business Act and, therefore, anyone can provide charging services for billing as can the electric power companies.
2. In November 2010, NEC Corporation announced the development of a cloud type EV charging system that promised a wide deploying area for the charging infrastructure. The system users will have access to a variety of authentication and electronic payment methods while the business operators will have the best energy management for the smart grid era such as, for instance, economical operation of chargers within the contracted limits in coordination with an electric power management system in the store.

 There have been yet other developments with regard to the deployment of charging infrastructures for various types of houses and parking facilities such as rental apartment houses (planned by Nissan, the city of Yokohama and Urban Renaissance Agency), condominiums (jointly planned by Nissan and Daikyo, Inc.), detached homes (Sekisui House, Itochu Property Development, Ltd.), and multilevel parking towers (Mitsubishi Heavy Industries). Among them, Sekisui House announced the EV charging receptacle will be a standard feature in its detached homes ordered in February 2011 or after. Homebuilders will promote them as environmentally-friendly houses.


EV-based car sharing, rent-a-cars and taxis gaining popularity

 Oryx Auto Corporation is operating 20 units of Mitsubishi i-MiEV in its rent-a-car fleet. In January 2011, the company announced plans to introduce 130 units of the Nissan Leaf EVs for its rent-a-car and car sharing businesses. Nissan will cooperate with the Kanagawa Prefecture in the introduction of electric taxicabs. Nissan will also join the "Hakone EV Town Project" with Mitsubishi Motors to promote the use of electric vehicles in tourist taxi, car sharing and rent-a-car operations.
