Design Issues
• No static storage
• Bi-directional charging and EV warranty
• DNO – a key stakeholder

Current situation and changes with V2B
• The Council already pays for renewable energy as its mains supply
• The V2B system will make more efficient use of that supply
723 April 2020
Daytime Operational Protocol
• Top-up charging as the EVs come and go during the day
• How much is from solar?

Evening & Overnight Protocols

Meeting SEEV4-City Objectives
• Increase in ultra-low emission km – by closely monitoring levels of solar generation coinciding with EV charging; to estimate solar input
• Increase in Energy Autonomy – by EVs discharging to City Hall during evening energy peak
• Avoid grid investments – by EVs discharging to City Hall during evening energy peak and scheduling the principal EV recharge for overnight

Leicester’s learning from SEEV4-City
• Provides first-hand experience of new approaches needed to decarbonise transport –whilst mitigating demand on the grid from increased EV use
• Flags need for new energy-transport skill sets
• Provides experience in line with ideas in key UK Govt strategy document

Simulated Results
• Due to the delays with the Leicester Pilot – project partner Northumbria University working on simulating results
• Using data supplied on;• Solar generation & mains supply
• EV charging
• EV telemetry
• V2B technical specification
• City Hall electrical details
