EV Charging and Home Charger

These tools cover the charging side. Charging Time and Cost per kWh work from a session, Charger Load checks a charger against your service and existing demand, EV Charger Wire Size gives the breaker and wire, the Level 2 charger amps calculator turns charger amps into kW, breaker size and miles per hour, the plug chart shows connector types by region, the kWh to watts converter turns energy into power over a time, and the kWh cost calculator prices a device, a number of kWh or a bill.

Tools in this group

• EV Charger Load Calculation (Panel Capacity) — Enter your service size and existing demand to see whether an EV charger fits and the largest charger current your panel can take.
• EV Charger Wire Size and Breaker Calculator — Enter the charger current and run length to get the breaker size, the minimum wire ampacity and the gauge for voltage drop.
• EV Charging Cost per kWh Calculator — Enter what a charging session billed and how much energy you got to see the real price per kWh.
• EV Charging Time Calculator — Enter the battery size, state of charge and charger to see how long charging takes and how much range you add.
• EV Plug Types Chart (Charge Connector Types) — Pick your region and charging type to see the EV plug and charge connector types, their nominal power and the adapters that exist.
• kWh Cost Calculator — Enter a device's watts and hours, a number of kWh, or a bill, with your own price per kWh, to see the cost.
• kWh to Watts Converter (and Watts to kWh) — Enter kilowatt-hours and the time they were used over to get watts, or enter watts and the time to get kWh.
• Level 2 Charger Amps (Amps, kW and Breaker Size) — Enter a charger's amps, its kW or your breaker size to see the power, the breaker it needs and the range it adds each hour.
