Why these inputs? Battery details determine how much energy is needed to reach your desired charge level. For example, a 60 kWh battery charging from 20% to 80% needs 36 kWh, which affects charging time based on your charger’s power.

Required. Your EV’s battery capacity, like the size of a gas tank. Check your EV’s manual, dashboard, or manufacturer’s website (e.g., Tesla.com). Example: Nissan Leaf is 40–62 kWh, Tesla Model 3 is 50–82 kWh.
Optional. The maximum AC charging power your EV can accept, found in your EV’s manual or on sites like ev-database.org. Example: Tesla Model 3 accepts up to 11 kW. If blank, the charger’s power is used.
Required. Your EV’s current battery percentage, shown on your dashboard or app. Example: 20% after a day’s commute.
Required. The battery level you want to reach. 80% is typical for daily use to balance speed and battery health. Example: Charge to 80% for a 200-mile trip.

Why these inputs? Charger details specify the power delivered, which directly impacts charging speed. For example, a 7.4 kW home charger takes about 5 hours to add 36 kWh, while a 22 kW public charger is faster but limited by your EV’s max rate.

Required. The type of charger you’re using. Home chargers are typically 3.6 or 7.4 kW; public chargers can reach 22 kW. Check your charger’s label or manual.

Why these inputs? Efficiency and environmental conditions adjust the effective charging rate. For example, 90% efficiency means some energy is lost as heat, and cold outdoor temperatures below 10°C can slow charging by up to 15%.

Required. The efficiency of energy transfer, typically 90–95%. Check your charger’s specs or use 90% as a default. Example: A 90% efficient charger delivers 6.66 kW from a 7.4 kW unit.
Required. Where you’re charging affects temperature impact. Indoor charging is stable; outdoor charging in cold weather may reduce speed. Example: Charging in an open lot in winter.
Required. The approximate temperature at your charging location. Below 10°C (50°F) may slow charging, especially outdoors. Example: 5°C in a winter garage.
