VoltSwap provides a standardized, modular, and swappable battery ecosystem designed for light electric vehicles (e.g., e-bikes, e-scooters, electric tuk-tuks, small delivery vans, electric watercraft) and small-scale stationary energy storage. It solves the problems of charging time, range anxiety, and high upfront battery costs by offering battery-as-a-service. Users can quickly swap depleted battery packs for fully charged ones at a network of stations, or utilize these modular packs for flexible energy storage at homes or businesses, thereby reducing grid strain and increasing renewable energy self-consumption.
