The global transition toward sustainable transportation relies heavily on the electrification of shared mobility fleets. Traditional linear models, which focus on individual vehicle ownership, often fail to address the high upfront costs and environmental impact of battery production. By adopting a circular business model, startups and policymakers can unlock new value pools while accelerating the adoption of electric vehicles (EVs) [3].

Circular business models for shared electric vehicles and battery leasing shift the focus from product ownership to service delivery. This transition involves decoupling the battery from the vehicle chassis, allowing for more efficient asset management. Through a vision for a sustainable battery value chain, industry leaders are proving that resource efficiency is the key to long-term profitability [2].

The core of battery-as-a-service

Battery-as-a-Service (BaaS) is the cornerstone of this circular approach. By separating the battery from the vehicle, operators significantly reduce the initial capital expenditure (CAPEX) required to launch a fleet. This model allows startups to offer competitive pricing for ride-hailing or delivery services [3]. Furthermore, it shifts the risk of battery degradation from the fleet operator to the service provider, who manages the asset’s health through circular economy for ev batteries: strategies for recycling and reuse.

Centralized health monitoring is another critical advantage of the BaaS model. Battery management systems (BMS) continuously transmit diagnostic data to the provider. This ensures that batteries are charged and maintained in ways that maximize their operational lifespan. When a battery no longer meets the performance requirements for mobility, it is seamlessly transitioned into a new role [1].

Optimizing shared mobility with battery swapping

Shared mobility fleets require high utilization rates to remain profitable. Traditional charging methods often lead to long periods of downtime, which limits the earning potential of the fleet. Battery swapping technology solves this by allowing vehicles to return to service in minutes rather than hours [3].

This approach also enables smarter energy management. Swap stations can charge batteries during off-peak hours when electricity prices are lower. This reduces operational expenses (OPEX) and helps balance the load on the local power grid. For policymakers, this infrastructure represents a strategic asset that supports broader electric vehicles and government incentive policies for investors.

The second-life potential of EV batteries

The circularity of the battery value chain does not end when a battery is retired from a vehicle. Once a battery reaches approximately 70% to 80% of its original capacity, it is considered ideal for second-life applications [1]. These repurposed batteries serve as stationary energy storage systems (ESS) for commercial and industrial sites.

By leveraging second-life EV batteries as a value pool, companies can support renewable energy integration. These systems store excess solar or wind power, providing a buffer that stabilizes the grid. This multi-stage lifecycle significantly reduces the carbon footprint associated with battery manufacturing [2].

Closing the loop with advanced recycling

Eventually, every battery reaches the end of its useful life. At this stage, hydrometallurgical recycling processes allow for the recovery of critical raw materials like lithium, nickel, and cobalt. Modern facilities can achieve recovery rates exceeding 90% to 95% [2]. These materials are then re-injected into the supply chain, reducing the need for environmentally damaging primary mining [3].

Policymakers play a vital role in enforcing extended producer responsibility (EPR) and establishing digital battery passports. These tools ensure transparency and accountability throughout the product lifecycle. By mandating the tracking of recycled content, governments encourage startups to design for recyclability from the very beginning [4].

Strategic considerations for startups

Startups entering this space must navigate several technical and logistical challenges. One primary hurdle is the lack of battery standardization across different vehicle manufacturers. Without standardized packs, swap stations cannot support a diverse range of vehicle brands [5]. Collaboration between OEMs and infrastructure providers is essential to overcome this fragmentation.

Additionally, the capital intensity of deploying swapping networks requires strong financial backing. Investors are increasingly looking for models that demonstrate long-term viability through recurring subscription revenue. By focusing on fleet partnerships, startups can secure the consistent demand needed to justify these infrastructure investments [1].

The role of policy in accelerating circularity

Governments can foster this ecosystem by creating regulatory frameworks that reward circularity. Financial incentives for second-life storage projects can bridge the gap between initial investment and profitability. Furthermore, clear safety standards for the transport and storage of used lithium-ion batteries are necessary to ensure industry growth [4].

By promoting the adoption of digital battery passports, policymakers can help consumers and businesses make informed choices. This transparency encourages the market to favor products with lower lifecycle emissions. As the global EV market matures, these circular models will become the standard for sustainable urban mobility [2].
