Home charging efficiency is 90% and electricity costs $0.16 per kWh, with no session fee.<\/p>\n<p>\\[ E_{added} = 60 \\cdot \\frac{80 - 20}{100} = 36 \\text{ kWh} \\]<\/p>\n<p>\\[ E_{drawn} = \\frac{36}{0.90} = 40 \\text{ kWh} \\]<\/p>\n<p>\\[ Cost = 40 \\cdot 0.16 + 0 = 6.40 \\text{ USD} \\]<\/p>\n<p><strong>Result:<\/strong> the session adds 36 kWh to the battery, draws 40 kWh from the outlet, and costs $6.40 \u2014 an effective price of $0.178 per kWh delivered.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to Use the Calculator<\/h2>\n<ol>\n<li>Enter your <strong>Battery capacity<\/strong> in kWh \u2014 use the usable capacity stated by the manufacturer, not the gross capacity if they differ.<\/li>\n<li>Set the <strong>Starting charge<\/strong> percentage, i.e. the level shown on the dashboard when you plug in.<\/li>\n<li>Set the <strong>Target charge<\/strong> percentage you want to reach.<\/li>\n<li>Enter the <strong>Charging efficiency<\/strong> \u2014 home AC charging typically runs 85\u201395%; leave the default of 90% if unsure.<\/li>\n<li>Enter the <strong>Electricity price<\/strong> per kWh from your utility bill or the public charging station's rate.<\/li>\n<li>Add any <strong>Session fee<\/strong> \u2014 a flat fee some public networks charge per session; enter 0 if there is none.<\/li>\n<li>Read the results: energy added to the battery, energy drawn from the charger, the estimated session cost, and the effective cost per kWh delivered.<\/li>\n<\/ol>\n<h2>What the Results Mean<\/h2>\n<p>The <strong>energy added<\/strong> is the useful energy that goes into the battery \u2014 it is what extends your driving range. The <strong>energy drawn<\/strong> is what the electricity meter actually records. The difference between the two is lost as heat in the charger, the cable, and the battery's internal resistance. This is why a 90% efficiency setting means the charger delivers about 11% more energy than the battery stores.<\/p>\n<p>The <strong>estimated session cost<\/strong> is what you should expect to pay for the session: metered energy times the electricity price, plus any flat fee. The <strong>cost per kWh delivered<\/strong> is often the most useful number for comparisons. It tells you the true effective price of each kilowatt-hour that reaches your battery, once losses and session fees are included. A station advertising $0.30\/kWh with a $2 session fee can work out far more expensive for a small top-up than it first appears.<\/p>\n<p>To estimate monthly costs, multiply the cost of a typical session by the number of sessions you do per month. You can also use the cost per kWh delivered together with your vehicle's efficiency (kWh per 100 km or miles) to compute a cost per mile \u2014 a direct comparison with fuel prices per gallon or liter.<\/p>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li><strong>Linear charge calculation:<\/strong> the calculator assumes each percentage point of the battery corresponds to a fixed amount of energy. In reality, charging slows down above roughly 80%, but the energy delivered still follows the state of charge, so the cost estimate remains accurate.<\/li>\n<li><strong>Efficiency varies:<\/strong> slow overnight AC charging is usually 85\u201395% efficient. Fast DC charging can drop to 80\u201390% at high power. Cold weather and very low or very high states of charge also reduce efficiency.<\/li>\n<li><strong>Use usable capacity:<\/strong> enter the battery capacity your car actually lets you use. Many manufacturers quote gross capacity, which can be several kWh higher.<\/li>\n<li><strong>Time-of-use rates:<\/strong> if your utility charges different prices at different hours, enter the rate that applies during the hours you plan to charge \u2014 overnight off-peak rates are often the cheapest.<\/li>\n<li><strong>Public charging networks:<\/strong> some price per minute or per session rather than per kWh. To model per-minute pricing, estimate the total kWh first and derive an equivalent price per kWh.<\/li>\n<\/ul>\n<p>To plan the rest of your electric driving costs, try our <a href=\"https:\/\/wpcalc.com\/en\/life\/ev-charging-time-calculator\/\">EV Charging Time Calculator<\/a> to see how long the session will take, the <a href=\"https:\/\/wpcalc.com\/en\/life\/ev-range-calculator\/\">EV Range Calculator<\/a> to see how far the added charge will take you, or the <a href=\"https:\/\/wpcalc.com\/en\/life\/car-lease-payment-calculator\/\">Car Lease Payment Calculator<\/a> if you are evaluating the full cost of a new EV.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Estimate the cost of an EV charging session from your battery capacity, starting and target charge level, charging efficiency, electricity price, and any session fee.
