1. Tevi’sEVchargingtool
Developing a tool to simplify decisionmaking for businesses

2. Rationale
• Helpbusinesses choosethe correctinfrastructure forthem
• Simplify thedecisionmakingprocess
• Identify costs
• Identify supportavailable
• Enhancethe chargingnetworklocally
• Notreproducewhatalreadyexists
• Buildanetwork ofbusinesses
• BuildonexistingTevi networks
• Tofindasolutiontoamultifaceted problem

3. Rationale
• Weaimedtodevelop atool tohelp businesses provide
infrastructurefor customers andother visitors
• OZEV* (OfficeforZeroEmission Vehicles) fundingmaybe
availablefor staff parkingrequirements
• Thetool directsthese userstothe correctplaceto

‘RAPID’ 43 – 120 kW
< 1 hour 1 – 5 hours > 5 hours /

Type 1, Type 2, Tesla
‘FAST’ 7 – 22 kW

‘SLOW’ 3 kW
Example:

Example:
Supermarkets,
restaurants, pubs,
theatres, hotels
Example:
Domestic, hotels
Charge profile – 0 – 80% ‘full charge’
Note: This profile assumes that an EV arrives with an entirely depleted battery, and the driver expects to fully charge. This rarely
occurs in the case of destination charging, with the majority of charging done at home. This is more prevalent at service stations, to
allow short stops during long journeys.
