1. Ions for EV
Understanding the spread of Electric Vehicle (EV) charging stations in Seattle's Capitol Hill area

2. The Problem
We intend to analyze public data to identify and display convenient EV charging stations
Where are EV stations installed vs. Where do they need to be?
Understanding which level of charging stations need to be
But also understanding if they physically can be installed

3. How Does this Impact the Community
Level One charging takes 10 hours to recharge
Homes usually accommodate Level 1
Lyft and Uber drivers relying on ridesharing as a form of income using EVs to cut 30% of their costs as a driver
Areas with not enough fast charging such as grocery stores are unreasonable as the average person does not spend 5+ hours in a parking spot

4. Electrical Context Level 1 Level 2 Level 3 (DCFC) 120 Volts 12-16 Amps
8-10 Hours
Level 2 
240 Volts
40 Amps
4-6 Hours
Level 3 (DCFC)
208/480 Volts
200/89 Amps
0.5 Hours

5. What We Used Public data on parking lots and garages in Seattle
Data on different levels of charging stations and voltages, where can stations be and where they need to be
Ideally, we would cross this data with PlugShare to see where parking spaces are versus EV parking spaces
Need a commercial license to access PlugShare data

6. How do we define "should" Where "should" EV stations be?
Mandated in 2016, Seattle wants 10% of all new parking to be EV designated
Seattle wants 30% electric vehicles by 2030
Seattle has codes for how many parking spots each building must have to accommodate cars in general
This gives us information into algorithms into where people go how long people stay and
We then use that metric, if a block of parking is not at least 10% EV designated, it needs more spaces

9. Our Proposition From our research and understanding:
- Installation of more DCFC at gas stations
- Access to higher amps
- Already socially integrated
- Convenient for highway entrance and exits
- Continuation of the 10% EV slots
- Verify the installations
- Further investigation into Residential charging convenience
