2. Background

Global shift toward zero-emission public transport (EU 2030, US 2035 targets).  

Reduced operating costs vs. diesel buses (lower energy/maintenance expenses).  

Challenges for Bus Fleets:  

High energy demand for daily operations (200-300+ kWh/bus).  

Limited downtime between shifts (need ultra-fast charging).  

Project Goal:  

Deploy a scalable DC fast-charging network to support [City/Region]’s transition to 100% electric bus fleets by  

3. Technical Specifications  

A. Charger Hardware  

Power Rating: 150-350 kW per charger (modular design for scalability).  

Voltage: 800V DC architecture (compatible with next-gen buses).  

Connector Standards: CCS2 (Europe), SAE J3105 (North America), or GB/T (China).  

Cooling System: Liquid-cooled cables for high-power efficiency.  



B. Charging Strategy  

Opportunity Charging: Top-up during layovers (15-30 mins).  

Overnight Charging: Full charge at depots (2-4 hours).  

Pantograph Systems: Overhead charging for automated alignment (e.g., ABB Terra HP).  



4. Infrastructure Design  

Site Selection:  

Bus depots, transit hubs, and high-traffic terminals.  

Proximity to grid substations to minimize upgrade costs.  

Grid Integration:  

On-site battery storage (peak shaving to reduce demand charges).  

Solar canopy integration (optional renewable energy source).  

User Interface:  

RFID/App-based authentication + real-time monitoring dashboard.  



5. Implementation Plan  

Phase 1 (Pilot)  

Timeline: Q1-Q3 2025  

Deliverables:  

Install 10 DC fast chargers at 2 key depots.  

Train staff on operations/maintenance.  

Test interoperability with 5 electric buses.  



Phase 2 (Scaling)  

Timeline: 2026-2028  

Deliverables:  

Expand to 50+ chargers across 10 locations.  

Integrate smart grid management software.  

6. Financials & ROI  

Capital Costs:  

Chargers: $150,000/unit (350 kW) × 10 units = $1.5M  

Grid upgrades: $500,000  

Total: $2M (Phase 1).  

Savings:  

Fuel: $200,000/year (vs. diesel).  

Maintenance: $50,000/year.  

Payback Period: 6-8 years (grants/subsidies may reduce to 4-5).  



7. Environmental & Social Impact  

CO2 Reduction: 1,000+ tons/year (Phase 1).  

Public Health: Eliminate NOx/PM emissions in urban areas.  

Equity: Prioritize charging access in underserved communities.  



8. Risks & Mitigation  

Grid Capacity: Partner with utilities for phased upgrades.  

Tech Obsolescence: Modular design allows future upgrades.  

Funding Gaps: Apply for federal grants (e.g., US DOT Low-No Program).  



9. Case Study Reference  

Example: Shenzhen, China  

100% electric bus fleet (16,000 buses) supported by 500+ DC fast chargers.  

Outcome: 48% lower energy costs, 1.3M tons CO2 avoided annually.  



10. Closing & Call to Action  

Next Steps:  

Secure municipal approval + funding commitments.  

Finalize partnerships (utilities, bus OEMs).  

Vision: “A zero-emission public transit system powered by 100% renewable energy by 2030.”
