EV Charging Load Profile Analyzer
Forecast EV charging peak loads and optimize grid capacity plans
What You Can Do
Transform raw charging data and market projections into actionable infrastructure capacity plans that balance capital expenditure with grid stability. You'll characterize load profiles by time and location, forecast peak demand periods that drive infrastructure requirements, and generate optimization recommendations for transformer sizing, feeder capacity, and DCFC unit mix based on duty cycles and growth scenarios.
Features
Analyze when, where, and how much power will be demanded across charging networks
Predict constrained periods and grid impact during high-utilization events
Right-size transformers, feeders, and DCFC units based on duty cycles and growth projections
Forecast utilization pattern shifts and revenue impacts from dynamic pricing strategies
Generate grid impact studies and infrastructure upgrade requirements for regulatory filings
Model network behavior during grid constraints and peak shaving events
Calculate transformer upgrade timelines and ROI for phased capacity expansion
Example Output
Example 1: Corridor Capacity Plan
Input: 50-station charging corridor with 30% DCFC/Level 2 mix, 3-year growth forecast
Output:
- Peak demand profile: 4.2 MW during 6-8 PM weekdays, 2.1 MW off-peak
- Transformer requirement: 5 MVA with N+1 redundancy (two 2.5 MVA units)
- Feeder sizing: 350 kcmil copper, underground conduit
- Year 1-3 phasing: 15 stations per phase, upgrade timeline by year
- Cost estimate: $2.1M infrastructure, $340K/year operating
Example 2: Demand Response Modeling
Input: Fleet depot with 200 vehicles, 2-hour charging window, grid peak avoidance contract
Output:
- Baseline demand: 8 MW continuous charging
- Peak shaving scenario: Stagger charging to 6 MW max, extend window to 4 hours
- Revenue impact: $85K annual demand response payments vs. $120K added OpEx
- Grid stability: Reduces local substation load by 25% during peak hours
