Battery swapping has emerged as a promising alternative to conventional charging for electric vehicle (EV) transport electrification. In a battery swapping station (BSWS), a depleted EV battery is replaced with a fully charged one in minutes, eliminating long charging times. The technology has seen rapid commercial growth, with over 8,000 stations deployed globally and a market projected to exceed $22 billion by 2035. However, this growth has revealed significant operational challenges. Current pricing models charge identical rates regardless of the health condition of the battery being swapped, meaning a user who returns a heavily degraded battery pays the same as one who returns a gently used battery. Determining how many batteries a station should maintain in inventory—too few leads to stockouts where arriving EVs cannot be served, while too many leads to idle capital—remains an open problem that most operators address through rules of thumb rather than systematic optimization. These challenges contribute to the financial difficulties faced by leading operators, several of whom have reported sustained losses as station utilization rates remain well below breakeven thresholds.
