Electric vehicle adoption is booming, but infrastructure lags with overloaded grids, fragmented charging, and costly upgrades. This EV energy and charging incompatibility is a global issue, compounded by proprietary solutions from few big companies, limiting user choice. CHOSEN is building an open, interoperable platform for ASEAN and the world, enabling true universal EV charging and an EV Energy Future. We optimize EV energy with AI-driven load control, virtual power plants, and seamless cross-border charging, ensuring a smarter, more efficient energy future. CHOSEN uniquely aggregates EV energy as a whole for the first time, regardless of charger brands, even those previously lacking communication solutions.
