Honda Mobile Power Pack

To achieve carbon neutrality, there are challenges in accelerating electrification across various products, including mobility. Key issues include “charging time,” “range/operating time,” and “battery cost.” As one approach to address these challenges and support the widespread adoption of electric products, we have developed portable and swappable batteries “Mobile Power Pack e: (MPP).” We are actively promoting its application not only for our own products but also for those of other companies.
By easily swapping in a fully charged battery, users are freed from waiting for charging and do not need to equip products with large batteries to ensure range or operating time. Additionally, by sharing MPPs across different products or through battery exchange stations, customers can reduce their battery cost burden. Moreover, effective use of batteries and increased operational rates can lead to a reduction in the overall battery production needed for society.
To achieve carbon neutrality, promoting the use of renewable energy is However, much of renewable energy generation depends on natural conditions and faces issues with adjusting power supply. By utilizing battery exchange stations as power storage, surplus electricity can be stored and shared efficiently. This approach allows for the effective use of clean electricity at all times, thereby facilitating the promotion of renewable energy use.
Honda is committed to the “Honda eMaaS” (Electric Mobility as a Service) concept, which aims to contribute to “freedom of mobility” and the “expansion of renewable energy use.” One of the key initiatives within this concept is the “expansion of MPP utilization.” Honda is not only developing battery packs and applicable products but also leading the standardization of portable and swappable batteries and building a shared system network. The goal is to enable wide use of these solutions, not just in Honda products but across products from other companies, thereby also serving as a part of the energy infrastructure.

Energy Service

Honda believes that accelerating the adoption of EVs requires more than just offering appealing products; it also involves creating an environment where customers can use EVs with confidence and enjoyment through comprehensive energy services. To achieve this, Honda is focusing on four key areas in its business development: eliminating concerns about running out of power and the inconvenience of charging, providing the convenience of home charging, helping customers save on electricity costs and utilize energy in emergencies, and promoting an eco-friendly lifestyle with zero CO2 emissions.
In addition, it is crucial to replace the energy source for EVs with clean, renewable energy as their adoption increases. To accelerate the integration of renewable energy across society, it is necessary to stabilize the power grid through demand-supply balance adjustments, given the instability of renewable energy generation. Honda has been addressing this challenge by researching Vehicle Grid Integration (VGI), where EVs contribute to stabilizing the power grid. Leveraging this expertise, Honda has developed energy services such as e:PROGRESS in Europe and Smart Charge in the United States.
Currently, in addition to providing charging services for homes and on-the-go, Honda is advancing a range of services including Vehicle-to-Home (V2H)^*1, which integrates EVs with the entire household, and Vehicle-to-Grid (V2G)^*2, which connects EVs to the power grid. These initiatives also involve efforts to deliver renewable energy to these systems. To achieve these goals, Honda is actively collaborating with like-minded partners.
The establishment of “IONNA,” announced in 2023, represents a collaborative effort among eight automakers to develop a high-power charging network in North America. The initiative aims to address concerns about running out of power and the inconvenience of charging by establishing over 30,000 charging points in urban areas and along highways. The goal is to provide an exceptional customer experience, with installation expected to begin within 2024.
Similarly, to contribute to stabilizing the power grid using EVs, Honda has established “ChargeScape” in collaboration with the BMW Group and Ford Motor Company. This initiative aims to provide an information platform that connects automakers with numerous utilities across the U.S. and Canada. By leveraging the extensive power adjustment capabilities of a large number of vehicles, ChargeScape seeks to stabilize the power grid. Additionally, the platform aims to maximize the use of renewable energy, reduce charging costs for customers, and lower expenses for utility companies.
In Japan, Honda has established “ALTNA Co., Ltd.” in a joint venture with Mitsubishi Corporation to develop new mobility services that reduce the total cost of EV ownership and to build a new energy business utilizing EV batteries over the long term. ALTNA will offer V1G (Vehicle-One-Grid) Smart Charge, an energy service that reduces charging costs for customers, while also aiming provide V2G services in the future, enabling energy exchange between EV batteries and the power grid. Additionally, ALTNA plans to repurpose batteries that have reached the end of their automotive life as storage batteries for the power grid, supplying grid stabilization power. This will contribute to the domestic circulation of scarce resources and further expand the use of renewable energy.
Honda views EVs not just as a mode of mobility but as products that can drive the evolution of energy systems for both customers and society. Therefore, Honda will continue to advance the development of energy management services.
