Nissan: Using EVs as storage batteries
At the 10th [International] Smart Grid Expo special session entitled "The Impact of EVs on the Power Grid", a presentation was given by Mr. Ryusuke Hayashi, Senior Manager, EV Operations Department, Global EV Division, Nissan Motor Co., Ltd., entitled “The Usage of EVs as Mobile Batteries”.
Recent EVs in the market have a larger battery capacity, and the Nissan Leaf offers versions equipped with 40kWh and 62kWh batteries. V2X (vehicle-to-everything) communication technology not only uses the power stored in the EV battery for powering a vehicle, but also uses it for external applications, such as V2H (vehicle-to-home) and V2G (vehicle-to-grid). In the Nissan presentation, Mr. Hayashi introduced to the audience, which included participants from the energy industry that EVs equipped with large-capacity batteries can have a positive impact on power grids (power distribution networks) and reduce infrastructure costs.
Some have stated that when the number of EVs increases, the increase in electricity required for charging will have a negative impact on the power grid. However, peak power loads can be contained by appropriately controlling the charging and discharging of EVs and by repurposing used batteries. Furthermore, increasing the number of EVs can have a positive impact on the power grid, such as stabilizing power generation using renewable energy, and create new business opportunities. With his presentation, Mr. Hayashi was calling for the promotion of renewable energy and EVs.
Honda: Battery sharing services
At the 11th [International] Rechargeable Battery Expo, a technical seminar on “Expanding Potentiality of New Mobility by Battery Technology” was held, and a presentation was given by Mr. Jun Iwamoto, Chief Engineer and LPL (Large Product Leader), Energy Platform Development Division, Life Creation Center, Honda R&D Co., Ltd. This report provides an outline of the Honda presentation entitled "The Popularization and Spread of Small Electric Mobility".
With the progress of CASE technologies, the expansion in the supply and demand of renewable energy, the growing awareness of the environment, and the electrification of mobility will continue to advance on a global basis. To facilitate the popularization of electric mobility, it is necessary to solve three issues associated with battery technologies: long charging time, short driving range, and high vehicle cost. Mr Iwamoto explained that battery sharing services represent one approach to popularizing electric mobility using current battery technology, and introduced a swappable battery pack (Honda Mobile Power Pack) and a battery pack exchange (Battery Exchanger) system. Analyzing the usage patterns of these products, and by making good use of energy and the data will enable Honda to achieve cleaner and more efficient transportation mobility solutions than gasoline vehicles.
