Planning tools
EV Charger Grid Capacity Calculator
Check how many EV chargers fit your transformer or supply: spare kW after existing load and a safety margin, plus input current per charger at 400 V.
Open the calculator →EV Charging Station Payback Calculator
Estimate the payback period of an EV charging station from your investment, sessions per day, energy per session, selling price, energy cost and fixed costs.
Open the calculator →EV Charging Time Calculator
Estimate how long a DC fast-charging session takes: battery size, charger power and the vehicle’s peak acceptance give minutes from your start level to 80 %.
