Why Most Commercial EV Charging Projects Cost More Than Expected
Why Most Commercial EV Charging Projects Cost More Than Expected
And how to design a system that actually works in the real world
Commercial EV charging is often treated as a hardware purchase. In reality, it is an infrastructure design problem.
The key insight: The charger is rarely the most expensive part of the project. Infrastructure is.
Stop Thinking About Charger Price
Every commercial EV charging project has three cost layers:
- Equipment: Chargers and hardware
- Infrastructure: Electrical upgrades, trenching, installation
- Operations: Energy, maintenance, uptime
Focusing only on hardware leads to poor decisions and higher total cost.
The Biggest Mistake: Overbuilding Power
Many projects default to 150–350 kW chargers. This often creates:
- Unnecessary electrical upgrades
- Higher install costs
- Longer timelines
- Fewer viable deployment locations
Reality Check
Most EVs today are limited to ~150–160 kW charging. Anything beyond that is often wasted.
More power ≠ better outcomes. It often means more cost with no benefit.
The Better Approach: Right-Sized DC Fast Charging
Splitvolt systems are designed for real-world applications—not spec sheets.
- 40–160 kW optimized charging range
- Full power available per connector (not split limited)
- Compact, lightweight systems
- Flexible installation (wall, pedestal, mobile)
Why Right-Sized Systems Win
Lower Total Project Cost
Avoid expensive infrastructure upgrades and reduce install complexity.
More Deployable Locations
Fit into parking garages, urban spaces, and constrained environments.
Faster Deployment
Less engineering complexity = faster time to revenue.
Better Real-World Performance
Optimized for fleet, workplace, and destination charging.
Physical Design Matters
- Typical 150kW systems: 350–550 kg, large footprint
- Splitvolt S-80 Duo: ~220 kg, compact design
This impacts:
- Transport costs
- Installation difficulty
- Site flexibility
Hybrid AC + DC: The Smartest Strategy
Most successful deployments combine:
- DC Fast Charging: High throughput where needed
- AC Wall Stations: Low-cost expansion across many stalls
This approach delivers:
- Lower cost per charging port
- Higher total site capacity
- Better ROI
DC handles speed. AC handles scale. Together, they optimize the system.
Design for Real-World Success
The most effective EV charging deployments focus on:
- Right-sized power levels
- Infrastructure efficiency
- System-level design
- Scalability and flexibility
Conclusion
The best EV charging systems are not the most powerful—they are the most deployable, efficient, and aligned with real-world use.
