Logistics Fleet Charging: 40% Energy Cost Reduction

Logistics Depot Smart Charging: How a 50-Van Fleet Cut Energy Costs by 40%

For logistics operators, fleet electrification is not just about replacing diesel vans with electric ones. The real challenge is managing charging costs without compromising delivery schedules. This case study shows how a regional logistics company in Zhejiang Province used FBK POWER's smart charging solution to cut depot energy costs by 40% while maintaining 100% fleet readiness.

Client Profile

• Fleet size: 50 electric delivery vans (last-mile urban delivery)
• Daily operation: 6 AM - 10 PM, 6 days per week
• Average daily mileage: 120 km per van
• Depot location: Industrial zone with time-of-use electricity pricing
• Previous setup: 20 x 7kW AC chargers, unmanaged charging

The Problem: Unmanaged Charging Was Expensive

Before FBK POWER's intervention:

• All vans plugged in at 6 PM when drivers returned
• Peak demand charges reached ¥180,000/month ($25,000)
• Grid connection was at 85% capacity, limiting expansion
• 3-4 vans daily had insufficient charge for morning routes

Smart Charging Solution

FBK POWER replaced the unmanaged AC setup with an intelligent DC charging system:

Smart Charging Algorithms

The system uses three optimization strategies:

1. Time-of-Use Shifting — Delays non-urgent charging to off-peak hours (11 PM - 6 AM)
2. Load Balancing — Distributes available power across all connected vehicles
3. Priority Scheduling — Charges vehicles with early morning routes first
