Design Issues

• No static storage

• Bi-directional charging and EV warranty

• DNO – a key stakeholder

623 April 2020

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

923 April 2020

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
