EV charging infrastructure development should mirror distributed solar's success rather than following traditional centralized infrastructure planning. Here's why and how:

Key Characteristics of Effective EV Charging Infrastructure:

• Dispersed locations across various settings (rooftops, parking lots, shopping centers)
• Large-scale deployment (similar to 2+ million distributed solar installations)
• Quick implementation (6-month typical deployment)
• Guided by central planning but not rigidly controlled

Problems with Current Central Planning Approaches:

• Over-specification of exact locations
• Rigid distance requirements between chargers
• Focus solely on highway corridors
• One-time planning versus adaptive deployment

Better Approaches for EV Charging Development:

1. Community-Based Planning

• Consider both highway and urban needs
• Account for apartment dwellers (30% of Americans)
• Balance traveler and resident requirements
• Include shopping areas with appropriate dwell times (15-30 minutes)

2. Flexible Implementation

• Allow for location adjustments based on power availability
• Consider site host partnerships and accessibility
• Focus on user experience and convenience
• Enable adaptation to changing market conditions

3. Demand-Based Deployment

• Build infrastructure progressively with market growth
• Current ratio in California: ~200 cars per charger
• Plan for 6-18 month development cycles
• Allow for technological advancement

Success Factors:

• Flexible guidelines rather than rigid requirements
• Weighted scoring systems for location selection
• Incremental implementation
• Regular program evaluation and adjustment
• Balance between immediate and future needs

By adopting these approaches, states and municipalities can create more effective, user-friendly EV charging networks that grow with demand and serve both local and traveling populations effectively.
