Formula
Total Cost = (Level 2 Count x L2 Cost) + (DC Fast Count x DC Cost)
EV infrastructure cost is calculated by multiplying the number of each charger type by its installation cost. Fuel savings compare annual electricity costs for EV charging against equivalent gasoline costs. CO2 reductions account for avoided tailpipe emissions minus grid electricity emissions.
Worked Examples
Example 1: Small City EV Infrastructure Plan
Problem:A city of 100,000 plans for 5,000 EVs. They need 250 chargers (80% Level 2 at $6,000 each, 20% DC Fast at $50,000 each). Calculate total infrastructure cost and fuel savings.
Solution:Level 2 chargers: 250 x 0.80 = 200 units x $6,000 = $1,200,000\nDC Fast chargers: 250 x 0.20 = 50 units x $50,000 = $2,500,000\nTotal infrastructure cost: $1,200,000 + $2,500,000 = $3,700,000\nCost per EV: $3,700,000 / 5,000 = $740\nAnnual electricity per EV: 30 kWh/day x 365 = 10,950 kWh\nAnnual electricity cost: 10,950 x $0.12 = $1,314\nEquivalent gas cost: (10,950 x 3.5 miles) / 28 mpg x $3.50 = $4,789\nAnnual savings per EV: $4,789 - $1,314 = $3,475
Result:Infrastructure: $3,700,000 | Savings per EV: $3,475/year | Payback: ~1.1 years per EV
Example 2: Fleet Electrification Analysis
Problem:A delivery company has 200 vans averaging 50 kWh/day. Calculate annual electricity costs vs gasoline costs, and CO2 reduction.
Solution:Annual kWh per van: 50 x 365 = 18,250 kWh\nTotal fleet kWh: 18,250 x 200 = 3,650,000 kWh\nElectricity cost: 3,650,000 x $0.12 = $438,000\nEquivalent miles: 18,250 x 3.5 = 63,875 miles per van\nGas equivalent: (63,875 / 28) x $3.50 = $7,984 per van\nTotal gas cost: $7,984 x 200 = $1,596,875\nFuel savings: $1,596,875 - $438,000 = $1,158,875\nCO2 avoided: (63,875 x 200 / 28) x 8.887 kg = 4,054 metric tons\nEV grid emissions: 3,650,000 x 0.42 / 1,000 = 1,533 metric tons\nNet CO2 reduction: 4,054 - 1,533 = 2,521 metric tons
Result:Annual fuel savings: $1,158,875 | Net CO2 reduction: 2,521 metric tons
