Toyota: Construction and Launch of a Large-capacity Sweep Energy Storage System from Reused Electrified Vehicle Batteries Connected to the Electrical Power Grid

In the future, demand for storage batteries is expected to grow as they become necessary supply-stabilizing tools when expanding renewable energy in the movement toward CO2 emissions reduction, a vital part of achieving carbon neutrality. At the same time, limited supplies of battery materials including cobalt and lithium, mean there is an ongoing need for environmentally conscious initiatives, such as reclaiming used electrified vehicle batteries for effective use as storage batteries. In response, JERA and Toyota began discussions in 2018 to establish battery reuse technologies, which eventually led to this large-capacity, grid-connected Sweep Energy Storage System.
Toyota's new storage system is equipped with a function called sweep, which allows the use of reclaimed vehicle batteries, which have significant differences in performance and capacity, to their full capacity regardless of their level of deterioration. The sweep function, developed by Toyota Central R&D Labs, Inc., is a device that can freely control energy discharge by switching electricity flow on and off (bypassing) through series-connected batteries in microseconds.
Furthermore, the sweep function also enables direct AC output from the batteries, while reusing onboard inverters eliminate the need for a power conditioner (PCS). That contributes to reducing costs and helps avoid power loss when converting from AC to DC by PCS, with the aim of improving effective energy use.
The project plans to operate grid storage batteries for recharge and discharge operations, connected to the Chubu Electric Power Grid Co., Inc. power distribution system from a facility (see below(1)) at JERA's Yokkaichi Thermal Power Station. JERA and Toyota aim to introduce approximately 100,000 kWh of supplied electricity in the mid-2020s, thereby not only reducing the overall cost of the energy storage system, but also contributing to reduction of CO2 emissions.

In addition, JERA is developing a low environmental impact process for recycling lithium-ion batteries for electrified vehicles(2), which Toyota plans to support by leveraging the expertise and knowledge it has accumulated through its battery recycling initiatives to date. By collecting used batteries and reusing resources, both companies hope to accelerate their efforts toward achieving a resource-recycling society.

JERA will continue to work proactively not only within the energy industry but also with leading companies in Japan and overseas to develop technologies such as battery storage systems and services that contribute to optimal energy utilization toward achieving a decarbonized and resource-recycling society.
Toyota actively promotes electrified vehicle adoption and pursues effective battery use, including electrified vehicle battery reuse, for the development of social infrastructure that will support the widespread adoption of electrified vehicles, expand the use of renewable energy, and promote resource recycling toward achieving carbon neutrality.

As described in the Basic Agreement signed in 2021, ENEOS and Toyota have decided to commence construction and operation of a hydrogen refueling station in close proximity to Woven City to produce and supply CO2-free hydrogen to Woven City and Fuel Cell Electric Vehicles (FCEVs) (Item 1 and 2 set forth below). Together, they will also research and design an efficient hydrogen supply and demand management system (Item 3 described below). The ENEOS hydrogen refueling station is scheduled to begin operations before the opening of Woven City in 2024-2025.
Items to be considered at the time of the Basic Agreement(1)
1. ENEOS to establish and operate a hydrogen refueling station in close proximity to Woven City
2. ENEOS to produce "green hydrogen," hydrogen derived from renewable energy, by electrolyzers at the aforementioned station and supply it to Woven City to be used at a stationary fuel cell generator that will be installed within Woven City by Toyota
3. Promote the use of hydrogen-powered fuel cell mobility for logistics in and nearby Woven City. Validate a base unit(2) of hydrogen demand for those mobility logistics as well as build a supply and demand management system
4. Conduct joint advanced research on hydrogen supply at the demonstration hub to be established within Woven City
The ENEOS hydrogen refueling station will "produce" the hydrogen that will meet the energy needs of "users," FCEVs in and around Woven City and Woven City as well. This collaboration expedites our progress toward realizing a truly carbon-neutral society and will facilitate and normalize clean energy operations first at Woven City and eventually the world.
Woven City is the project of Toyota aiming to create happiness through mobility of "people," "goods," and "information." It is focused on three pillars. That are: Human-Centered City that makes people happier in their everyday lives, considering the needs of different kinds of people before and during the development of technology; Living Laboratory, the first-of-its-kind test track for mobility where researchers, engineers, and scientists demonstrate innovative ideas and future technologies both virtually and in the real world; and Ever-Evolving City, rooted in Toyota's kaizen (continuous improvement) approach, is focused on new ideas that provide better mobility of information, goods, and people.
(1) Announced on May 10, 2021 "ENEOS and Toyota Come Together to Make Woven City the Most Hydrogen-Based Society"
(2) Hydrogen can be supplied to FCEVs even during power outages by using stored hydrogen to operate a hydrogen refueling system with a stationary fuel cell generator. This allows the external power supply function of FCEVs to be utilized to provide power support where electricity is needed.
(3) The "base unit" is a standard of measurement required to ensure a result that is both practically valuable to users and commercially viable.
