- EV drivers planning a charge
- Worth noticing
- It models charging in 1% battery steps and lets drivers drag a vehicle-specific DC charging curve.
Field notes
Estimates are built by summing energy and time across 1% state-of-charge steps, applying the lower of charger output and the car’s acceptance at each step, then allowing roughly 10% for losses. Users can save multiple cars and chargers, set battery size, efficiency, maximum charge rate, price, and a custom charging curve. The page identifies battery temperature and preconditioning as factors it cannot model.
