Battery-as-a-Service (BaaS) and EV battery swapping
Battery-as-a-Service (BaaS) and EV battery-swapping models separate battery ownership from the vehicle, allowing fleet operators or consumers to lease or exchange batteries instead of purchasing them outright. This reduces upfront capital expenditure, eases financing constraints for commercial fleets and accelerates vehicle turnover by treating the battery as a service asset rather than a long-lived capital component. Swapping systems rely on modular, standardized battery packs and automated stations where depleted batteries can be exchanged for charged units within minutes, reducing charging-related downtime and enabling high daily mileage or tightly scheduled logistics operations.
BaaS platforms also centralize battery charging, health monitoring and lifecycle management. By charging batteries at controlled rates, operators can improve asset longevity, reduce load peaks on the grid and shift electricity demand to off-peak periods. This supports more predictable grid interactions compared to unmanaged plug-in charging and creates opportunities for coordinated demand response as fleets scale. Centralized oversight enables consistent assessment of battery state-of-health, facilitates second-life allocation into stationary storage and ensures recycling pathways are integrated from the outset.
For power systems facing rapid growth in commercial EV fleets, BaaS and battery-swapping models provide a structured mechanism for electrification without requiring extensive upgrades to depot infrastructure or large scale fast-charging hubs. The model offers an alternative pathway for high-utilization sectors such as delivery services, urban logistics, ride-hailing and municipal fleets, where operational continuity and predictable energy availability are central to business performance.
Main outcomes of the solution
- Affordability: Reduces total cost of ownership by avoiding upfront battery procurement, spreading expenditure through leasing or service fees and reducing operational losses from charging-related downtime.
- Reliability & Flexibility: Provides rapid, automated battery swaps that enable continuous vehicle operations and predictable energy availability, supporting sectors with tight scheduling requirements such as logistics and commercial transport.
- Business Value: Enhances fleet performance through shared battery assets, more stable operating costs and service models that scale with fleet growth and long-term electrification strategies.
Key deployment and scaling factors:
- Establish interoperability and standardization across OEMs and battery suppliers to enable safe, compatible swapping architectures.
- Deploy modular, automated swap stations at volume to achieve geographic coverage and operational efficiency for commercial fleets.
- Align with regional electrification and transport policies to integrate BaaS into city or national zero-emission mobility strategies.
- Develop viable service pricing structures that balance incentives across fleet operators, infrastructure providers and battery owners.
- Implement robust safety, data and battery health monitoring systems to ensure asset reliability and manage lifecycle performance.
Case Studies
Mitsubishi Fuso, Mitsubishi Motors, Ample, and Yamato Transport (2025), Japan
In 2025, Mitsubishi Fuso Truck and Bus Corporation, Mitsubishi Motors Corporation, Ample and Yamato Transport announced a pilot program to deploy a battery-swapping network for commercial EV fleets across Tokyo. The multi-year initiative plans to introduce more than 150 battery-swappable electric vehicles, including light-duty trucks and compact commercial models, supported by approximately 14 modular, automated swap stations.
The stations are designed to complete fully automated battery exchanges in roughly five minutes, reducing charging-related downtime and enabling continuous operations for last-mile logistics and delivery services. The Tokyo deployment builds on earlier pilot work in Kyoto and is supported by Tokyo Metropolitan environmental programs.
The initiative illustrates how BaaS and battery-swapping models can enable higher-utilization fleets, support rapid electrification of urban logistics and test scalable operational frameworks for commercial transport applications in dense metropolitan areas.[1]
Bandera Electric Cooperative and Base Power (2025), USA
In 2025, Bandera Electric Cooperative in Texas partnered with Base Power on a residential battery storage program that provides homeowners with affordable whole-home battery backup systems. Under this partnership, Base Power supplies and manages the battery systems while members pay a monthly fee as part of a subscription structure, with no upfront cost required for installation. The distributed network of home batteries can act as an aggregated resource, allowing the cooperative to operate the systems in real time to support grid performance and enhance resiliency. The program is structured so that the cooperative can balance demand and grid operations by drawing on the distributed battery capacity across participating homes, while members benefit from backup power during outages and potential savings through time-of-use optimization. This initiative reflects a utility-driven approach to deploying distributed energy storage through regulated partnership arrangements.[2]
