Key Features of the eTruck Fleet Simulator
1. Fleet-Wide Battery Management (10 MWh Total Capacity)
Monitor 20 Tesla Semi trucks simultaneously, each with 500 kWh battery capacity. Track State of Charge (SoC), charging power, and range predictions across your entire fleet. The dashboard displays real-time status: vehicles charging, available, on route, or in maintenance.
2. Megacharger Station Control (3× 1.2 MW)
Three Megacharger stations with OCPP 2.0.1 integration provide up to 3.6 MW of charging capacity. Monitor connector status, session energy, cable temperature, and liquid cooling system performance. Each charger supports two vehicles simultaneously.
3. Smart Charging Strategy with Spot Price Integration
The intelligent charging algorithm optimizes costs based on real-time electricity prices:
- CHARGE Mode: When spot prices drop below 40 €/MWh, all available vehicles charge at maximum power
- V2G Mode: When prices exceed 100 €/MWh, idle vehicles discharge to the grid for revenue
- SMART Mode: Normal operations balance fleet readiness with cost optimization
4. V2G Arbitrage Revenue
Vehicle-to-Grid (V2G) capability transforms your parked fleet into a revenue-generating asset. During peak pricing hours (typically 17:00-21:00), idle trucks can export power back to the grid. With 4 vehicles at 200 kW each, you can generate 800 kW of V2G capacity—earning €150-400 per day during high-price events.
5. 7-Day Simulation with Time-Travel
The dashboard includes a powerful simulation engine with 2,016 data points covering 7 days of realistic fleet operations. Use the playback controls to:
- Play/Pause simulation at 1x to 60x speed
- Jump to any date within the simulation range
- Analyze duck curve pricing patterns
- Study depot occupancy trends throughout the week
6. Depot Occupancy Patterns
The simulation models realistic depot behavior:
- Night (22:00-06:00): 90% of fleet in depot, optimal for overnight charging
- Morning Departure (06:00-09:00): Fleet deploys for deliveries
- Work Hours (09:00-17:00): Only 40% in depot
- Evening Return (17:00-20:00): Fleet returns for evening charging

Frequently Asked Questions
What is the total battery capacity of a 20-truck eTruck fleet?
A fleet of 20 Tesla Semi trucks, each with a 500 kWh battery, provides a total capacity of 10 MWh (10,000 kWh). This represents significant energy storage that can be leveraged for V2G services and demand response programs.
How much power can a Megacharger deliver?
Tesla Megachargers are designed to deliver up to 1.2 MW (1,200 kW) per unit. With three Megachargers, a depot can provide 3.6 MW of total charging capacity, enabling rapid charging of multiple trucks simultaneously.
What is OCPP 2.0.1 and why is it important?
OCPP (Open Charge Point Protocol) 2.0.1 is the latest standard for communication between charging stations and management systems. It enables smart charging, V2G functionality, and real-time monitoring across different charger manufacturers.
How does V2G (Vehicle-to-Grid) generate revenue?
V2G allows parked electric trucks to discharge power back to the grid during high-price periods. With spot prices exceeding 100 €/MWh during peak hours, a fleet exporting 800 kW for 2 hours can earn €160 or more per session.
When should eTrucks charge to minimize costs?
The optimal charging window is during low-price periods, typically between 10:00-15:00 (solar valley) and 00:00-06:00 (night). Smart charging algorithms automatically prioritize these periods when spot prices drop below 40 €/MWh.
What is the duck curve and how does it affect fleet charging?
The duck curve describes the daily pattern of electricity demand and solar generation. Prices are lowest during midday solar peak and highest during evening demand (17:00-21:00). Smart fleet management exploits this pattern for arbitrage.
How many vehicles can charge simultaneously with 3 Megachargers?
Each Megacharger has two connectors, allowing up to 6 vehicles to charge simultaneously. However, power sharing may occur when multiple vehicles charge on the same unit, reducing individual charging speeds.
What is the typical range of a Tesla Semi with 500 kWh battery?
A fully charged Tesla Semi with 500 kWh battery provides approximately 450-500 km of range under optimal conditions. Cold weather, heavy loads, and highway speeds can reduce this to 350-400 km.
How does temperature affect eTruck charging speed?
Battery temperature significantly impacts charging. Optimal charging occurs between 20-35°C. The Megacharger's liquid cooling system maintains cable temperatures below 55°C even at maximum power.
What grid connection is required for a 20-truck depot?
A depot with 3 Megachargers (3.6 MW total) plus auxiliary loads typically requires a 4-5 MW grid connection. This often involves a dedicated medium-voltage transformer and utility coordination.
How much can peak shaving save for an eTruck depot?
By limiting charging during peak demand periods, a depot can reduce demand charges by 20-40%. For a 3.6 MW depot, this translates to €2,000-5,000 monthly savings depending on utility rate structure.
What is the ROI timeline for eTruck charging infrastructure?
With €120,000-180,000 annual savings from smart charging and V2G revenue, typical infrastructure investments (€300,000-500,000 for 3 Megachargers) achieve payback in 2-3 years.
Can the dashboard integrate with existing fleet management systems?
Yes, the API provides endpoints for fleet status, charger data, and historical analytics. Integration with TMS (Transportation Management Systems) and telematics platforms is supported via JSON REST API.
How accurate is the 7-day simulation?
The simulation models realistic patterns including depot occupancy (night 90%, day 40%), duck curve pricing, charging strategy switches, and temperature effects. Data is generated at 5-minute intervals (288 points/day).
What maintenance is required for Megachargers?
Megachargers require quarterly inspections, annual cable replacement (high-use connectors), and cooling system maintenance. Remote monitoring via OCPP enables predictive maintenance before failures occur.
