How this service works
Electric vehicle charging time, cost and range added from battery size, charge levels, charger power or circuit, and price.
Output
Returns a JSON object with charging time in hours and minutes, total electricity cost, energy added (net kWh), charging losses (kWh), charger power (kW), miles of range added (if efficiency provided), a plain-language summary, verdict, and any advisory reasons or warnings about the inputs.
Example use cases
Overnight home charging plan
“My EV has a 75 kWh battery and is at 15% right now — I want to charge it to 100% overnight on my 240V/50 amp home circuit. How long will that take and what will it cost me at $0.12 per kWh?”
Road trip top-up cost estimate
“I need to add about 150 miles of range to my car, which gets 3.5 miles per kWh. My battery is 82 kWh and I'm at 30%. How much will it cost to charge to 80% at a public Level 2 charger charging $0.25 per kWh?”
New charger sizing decision
“I'm installing a home EV charger and want to know how fast I could charge my 100 kWh battery from 10% to 80% with an 11 kW charger versus a 7.2 kW charger — and what the electricity cost difference would be at $0.15 per kWh?”
Technical details
Endpoint
GEThttps://home-energy-calc.x402tookit.com/ev-charging?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need accurate EV charging calculations grounded in real electrical parameters (battery kWh, circuit amperage/voltage, charger kW) rather than rough app estimates. It is especially useful for home energy planning — comparing charger tiers, estimating overnight charge completion, or computing cost with block pricing. It supports both simple level-based inputs (level1/level2) and precise electrical circuit specs, making it suitable for both consumers and energy planning agents.
Side effects
- Missing required parameters (batteryKwh, startPercent, endPercent) returns a validation error
- endPercent must be greater than startPercent; invalid range returns an error
- chargerKw, breakerAmps, or level must be specified for power; missing all three may cause degraded or null results
- Out-of-range values (e.g. batteryKwh > 300, efficiency outside 0.7–1) return validation errors
- pricePerKwh or milesPerKwh omitted causes cost or range fields to return null
- Conflicting power inputs (chargerKw + breakerAmps + level) may lead to ambiguous results
