如何计算EV Fleet Total Cost
learn.whatIsHeading
The EV Fleet TCO Calculator helps businesses estimate the total cost of electrifying their vehicle fleet compared to maintaining gas or diesel vehicles, covering acquisition, fuel, maintenance, infrastructure, and downtime costs.
公式
Fleet TCO = (Vehicle Cost x Fleet Size) - Credits + (Annual Fuel + Maintenance + Insurance + Infrastructure) x Years
- N
- Fleet Size (vehicles) — Total number of vehicles in the fleet
- AMD
- Annual Miles per Vehicle (miles/year) — Average annual mileage per fleet vehicle
- Ci
- Infrastructure Cost ($) — Total cost for depot charging installation
- TC
- Commercial Tax Credits ($) — Federal and state incentives per commercial EV
分步指南
- 1Enter fleet size, vehicle type (sedan, van, truck), and annual miles per vehicle
- 2Input current fleet fuel costs and maintenance expenses
- 3Add charging infrastructure costs (Level 2 or DCFC depot chargers)
- 4Compare 5 and 10-year TCO for ICE fleet vs EV fleet with all incentives applied
例题解析
输入
20-vehicle delivery fleet, 25k mi/yr each, replacing gas vans ($35k) with EV vans ($55k)
结果
ICE fleet 10-yr TCO: $2.1M. EV fleet 10-yr TCO: $1.65M (after $150k in credits + $380k fuel savings). EV saves $450k.
输入
50-vehicle sedan fleet, 30k mi/yr, $50k EVs vs $32k gas sedans
结果
Break-even at year 5.2. 10-year EV advantage: $625,000 across the fleet.
常见错误注意事项
- ✕Not including charging infrastructure costs ($2,000-$6,000 per Level 2 station, $30,000-$100,000 per DCFC)
- ✕Forgetting the commercial clean vehicle tax credit (up to $7,500 per vehicle under 14,000 lbs, $40,000 for heavy)
- ✕Underestimating EV uptime advantage — EVs have 40% fewer maintenance events and less unplanned downtime
常见问题
When does an EV fleet break even vs gas?
Most EV fleets break even in 3-6 years depending on annual mileage, fuel prices, and incentives. High-mileage fleets (30k+ mi/yr per vehicle) break even fastest due to larger fuel savings.
How much charging infrastructure does a fleet need?
A common ratio is 1 Level 2 charger per 2-3 vehicles for overnight depot charging. For vehicles needing midday top-ups, add DCFC units at a ratio of 1 per 8-10 vehicles.
