How many EV chargers do I need for my fleet?

The number of chargers needed depends on your fleet size, daily mileage per vehicle, charger power level, and available charging window. A general rule is to start with a 3:1 to 5:1 vehicle-to-charger ratio for Level 2 chargers, and 8:1 to 15:1 for DC fast chargers, adjusting based on your specific operational demands and duty cycles.

What is the best charging strategy for a commercial EV fleet?

The most cost-effective strategy is overnight Level 2 charging at a depot for vehicles with predictable daily routes. Supplement with DC fast chargers for high-utilization fleets or vehicles needing mid-day top-ups. Smart charging software that staggers sessions based on priority and grid capacity can reduce infrastructure costs by 20-40%.

How much does it cost to install EV fleet charging infrastructure?

Level 2 charger installation typically costs $3,000–$6,000 per port including hardware and electrical work. DC fast chargers range from $25,000–$150,000+ per unit depending on power output. Site preparation, utility upgrades, and permits can add 20-50% to total costs. Many regions offer grants and incentives that can offset 50-80% of installation expenses.
