Home charging is the most convenient and cost-effective way to power your electric vehicle, saving up to 5x compared to public chargers. The EV Home Charger Optimizer works for everyone, everywhere! Input your EV’s details, home electrical setup, and optional cost or solar data to find the ideal Level 2 charger, verify your home’s electrical capacity, and estimate charging time and costs in your local currency. Whether you’re new to EVs or upgrading your setup, our beginner-friendly tool guides you step-by-step to a safe, efficient, and future-proof charging solution!

Why these inputs? General settings let you choose the units and currency for calculations, ensuring distances, efficiencies, and costs match your country’s standards. For example, selecting kilometers and euros (€) ensures your daily driving distance and electricity costs are calculated correctly for Europe.

General Settings

Distance Units:
Required. Choose miles (used in the US, UK) or kilometers (used in most other countries) for distance and efficiency inputs. This affects how you enter daily distance and efficiency below. Currency:
Required. Select your local currency to display all costs (e.g., electricity, charger purchase). Choose from major currencies like US dollars ($), euros (€), or Chinese yuan (¥). This ensures cost estimates match your local economy.

Why these inputs? EV details help calculate how much electricity your vehicle uses daily, which determines charging time and costs. For example, a Tesla Model 3 with a 60 kWh battery driving 30 miles daily needs about 9 kWh, affecting charger selection and cost estimates.

EV Details

Battery Capacity (kWh):
Required. Your EV’s battery size, like a gas tank for electricity. Check your EV’s manual, dashboard display, or manufacturer’s website (e.g., Tesla.com for Tesla models). Example: Nissan Leaf is 40–62 kWh, Tesla Model 3 is 50–82 kWh. If unsure, contact your dealer. Daily Driving Distance (miles):
Required. Your average daily driving distance. Estimate based on your daily commute or check your car’s odometer over a week and divide by 7. Example: 30 miles (US) or 48 km (Europe). Apps like Google Maps can track your trips. EV Efficiency (kWh/100 miles):
Required. How much electricity your EV uses per 100 miles or km, like fuel efficiency. Check your EV’s manual, dashboard, or manufacturer’s website. Default is 30 kWh/100 miles (18.6 kWh/100 km), typical for many EVs. Example: Tesla Model 3 is ~25–30 kWh/100 miles.

Why these inputs? Your home’s electrical setup determines if it can support an EV charger safely. For example, a 200A panel with 240V can handle a 7.4 kW charger, but a 100A panel may need an upgrade, which the tool checks to ensure safety.

Home Electrical Setup

Electrical Panel Capacity (amps):
Required. The total capacity of your home’s electrical panel, found on the label of your main breaker panel (usually in your garage, basement, or utility room). Look for a number like 100A, 150A, or 200A. Most homes have 100–200A. If unsure, ask your electrician or landlord. Voltage (V):
Required. The voltage for your Level 2 charger, typically matching your country’s standard. Check your home’s electrical panel or consult your electrician. Default is 240V (US, Australia), but use 230V for Europe, 220V for China, or your local standard. See voltage by country.

Why these inputs? Charger details specify the power of your Level 2 charger, which affects charging speed and electrical load. For example, a 7.4 kW charger charges a 60 kWh battery faster than a 3.6 kW one but requires more panel capacity.

Charger Details

Charger Power (kW):
Required. The power rating of your Level 2 charger, which determines charging speed. Check the charger’s label, manual, or product listing (e.g., on Amazon or retailer websites). Common options are 3.6 kW (slower), 7.4 kW (standard), 11.5 kW (faster), or 19.2 kW (high-end). Select “Custom” for other values.

Why these inputs? Electricity costs help estimate how much you’ll spend charging at home versus public stations, highlighting savings. For example, if your home rate is €0.15/kWh and public charging is €0.40/kWh, the tool shows you could save €100s yearly by charging at home.

Optional: Electricity Costs

Standard Electricity Rate (per kWh):
Optional. Your home electricity cost per kWh. Check your utility bill (look for “price per kWh” or “energy charge”) or your online utility account. Example: 0.15 in your currency (e.g., $0.15/kWh in the US, €0.20/kWh in Europe). Skips home charging cost estimates if blank. Off-Peak Electricity Rate (per kWh):
Optional. A lower rate for off-peak hours, if offered by your utility. Check your bill or utility’s website for “time-of-use” rates. Example: 0.10 in your currency. Requires off-peak hours below. Skips off-peak cost estimates if blank. Off-Peak Hours:
Optional. The time window for off-peak rates, if applicable. Check your utility bill or website. Example: 10 PM–6 AM. Needed for off-peak cost estimates. Skips off-peak cost estimates if blank. Public Charging Rate (per kWh):
Optional. The average cost at public charging stations. Check receipts from public chargers or estimate based on local rates. Example: 0.40 in your currency. Defaults to 2x standard rate (if provided) or 0.40 if blank.

Why these inputs? Charger and installation costs help estimate the total upfront investment for your setup, including potential rebates to reduce costs. For example, a charger costing $800 with a $500 rebate lowers your net cost to $300, which the tool calculates.

Optional: Charger and Installation Costs

Charger Cost ($):
Optional. The purchase price of your charger. Check the price on retailer websites (e.g., Amazon, manufacturer sites) or quotes from suppliers. Example: 800 in your currency. Defaults to 500–1200 if blank. Installation Cost ($):
Optional. The cost to install your charger, including wiring and labor. Get a quote from a licensed electrician or estimate based on local rates. Example: 1200 in your currency. Defaults to 800–2000 if blank. Rebate Amount ($):
Optional. Any rebates or incentives for EV chargers. Check with your utility provider, local government, or energy office for available programs. Example: 500 in your currency. Skips rebate estimates if blank.

Why these inputs? Solar setup details estimate if your solar panels can power your EV sustainably, reducing reliance on grid electricity. For example, a 200W solar panel in a sunny area might cover half your EV’s daily needs, extending battery life.

Optional: Solar Setup

Solar Panel Size (W):
Optional. The total wattage of your solar panels, found on the panel labels or system specs from your installer. Example: 200 W for a small portable setup. Skips solar estimates if blank. Solar Charging Efficiency (%):
Optional. Efficiency of your solar charging system, accounting for losses (e.g., cables, controller). Default is 80%, typical for most setups. Adjust if you have specific data from your installer. Skips solar estimates if blank. PVOUT Value from Global Solar Atlas:
Optional. Your location’s solar potential, measured in kWh/kWp/day. Go to Global Solar Atlas, click your location, and copy the PVOUT value. Example: 3.117 for Paris. Skips solar estimates if blank.

Why these inputs? Major appliances use significant electricity, which competes with your EV charger for your home’s electrical capacity. For example, adding an oven using 40A ensures the tool checks if your 100A panel can handle both, preventing overloads.
