EV Infrastructure Building Code Questions

1. Should this cover other types of infrastructure such as fuel cell charging stations, and battery swapping stations?

me>> yes

2. Should street lights have 110V plugs for EVs to plug into? Who pays for electricity, parking?

me>> Yes! Partner with Car2Go? They have a deal for free parking with their Smart ICEs. I believe they plan to add Smart EVs.

3. Do we need a law like the one Hawaii passed - it's a law that Hawaii adopted to lay out the rules for EV infrastructure?

File:Hawaii Strata SB2231 CD1 .pdf < Image links are better because they account for which pages link to a file.
Media:Hawaii_Strata_SB2231_CD1_.pdf < These go directly to the file, but users can click to the file from the Image page also.
me>> Sounds like a good idea, but I wish we could dump the legalese for plain English http://www.languageandlaw.org/PLAINENGLISH.HTM

4. If we were to start providing for future large-scale EV charging infrastructure in new and renovated buildings, what’s a reasonable electric load per 100 spaces to assume? It would be different for apartment buildings, office buildings, retail & entertainment, hospitals, schools?

me>> Start with L1 for 50% of spaces, but provision for (conduit, etc) for L2 (10kW?) SmartGrid for all 100). A look at EV sales and surveys would help us understand and stay slightly ahead of demand. I could see the evolution something like Gen1: 50% L1, 5% L2/DCFC; Gen2: 95% L1/L2 SmartGrid, 5% DCFC; Gen3: 10% L1; 90% L2/DCFC SmartGrid

5. Would we assume that the great majority of drivers charge up overnight at home, and not really need charging at the office or clinic or movie theater? In that case, we’d just assume a small proportion of cars (5% or less) would be charging at commercial establishments at any one time, but that a large proportion (50% or more) would need charging sometime between 7:00 PM and 7:00 AM at an apartment building.

Answer: I think most people charge up at home, if they can. SEVA's charging station survey may shed some light on this. Also might check out other sources of data like Dept of Commerce at WA state.
me>> I agree

6. In the garages, it doesn’t seem reasonable to provide for outlets at every single parking space. Maybe there’d be a few short-term parking spots for those cars that needed active charging (in case someone needed to drive to an appointment that morning), and a larger number of parking spots for people who only wanted to have their cars charged sometime before they left the office at 5:00…

Answer: Vancouver has come to the conclusion that "every dwelling" should have access to a 110V outlet for charging purposes. This applies to all types of housing (not necessarily commercial or workplace).
me>> Agree. Should be L1 available to most, but also L2 or DCFC for those who need a faster charge

7. How much should we plan for in 10 years, 20 years? Particularly when it comes to charging away from home. Right now there are rougbly 3,000 gas stations in Washington. If we equate those to DCFC then we've got a way to go.

me>> see 4

8. What is the "demand factor" and how is it used in the code?

9. Should we include Seattle Article 625.27 into our proposed code? It simply requires provisions for future installation of equipment in the electrical room and a path to get to the parking garage (provided by Sandra at City of Seattle Sustainability Office):

File:Seattle Electric Code Article 625.27.doc
me>> I think so. See 4

Must Read Documents

This document is a must read. It's a writeup by the Washington State Dept of Commerce providing guidelines on EV infrastructure regulations in Washington State.

File:Washington EVI full report.pdf

This is another must read document. It contains draft EV infrastructure ordinances which seem to be similar to those in the just prior document.

File:Washington Model Ordinaces.pdf

This is some good information from IEEE about why we should be using L1 chargers in most places and why L2 at home and work is not a good idea. Should definitely read this:

File:Battery-not-a-tank-1.pdf

This has some approximate costs for installing EV infrastructure - not sure if this is BC dollars nor who developed it. Should talk with Don about that.

File:Costing Single Family v2.xls

Very good article about EV infrastructure in multi-family units in LA:

File:EV Charging in LA MUDs.pdf

Proposed EV Infrastructure Codes

Should we simply start with the Regional Code Council's?

Lessons from Vancouver BC:

a. After 5 years of use, BC is changing to use "Each dwelling unit shall be provided with an electrical outlet box wired in accordance to the electrical code for the purpose of electric vehicle charging." This will be less problematic

b. We need to insert language into both the electric code and the building code so they cross reference each other. Electric inspectors only inspect electrical while building inspectors don't inspect electric so things fall thru the cracks.

c. They came to the conclusion that 110V outlets in all housing should be the standard. It accommodates the vast majority of user needs and has the least impact on the grid. It also provides flexibility of installing permanent and moveable EVSE.

d. BC initially codified a lot of "design" in their electric codes and they are not removing a lot of that and simply specifying the minimums. This provides some flexibility to developers in how to meet the code in a cost effective manner.

e. FOCUS ON THE 120v OUTLETS FIRST! Too many bureaucrats and initiatives are too focused on the expensive Level-2 and L3 EV quick charging stations and promoting public EV charging infrastructure as a way to combat Range Anxiety. This focus on public charging which is only the tip of the Charging Pyramid as shown above is doing more to underimine the adoption of EV's than to help them. Range anxiety is a self-fulfilling prophecy if we keep focusing on the need for fast routine public charging. Also the emphasis on charging speed is completely misplaced. At every level of the charging pyramid, except the top, charging is not a separate go-to process but is just an added 5 seconds on the parking process. The only place where EV charging speed is paramount is along the interstates, where the only reason for being there is to charge and charge fast to get from point-A to point B. Every other level of the charging pyramid is simply charging conveniently while we are parked. And when you are parked for 4 hours or more, 120v standard outlet charging is just fine. Park at-work, Plug-in at work and double your range!

f. L2 Chargers at work are ineffective: The expensive high-cost Level-2 quick chargers at work locations and campuses makes little sense for the employee or employer. Employers are not going to want their people doing musical-chairs in the parking lot every hour and rotating one EV off the charging station, and then rotating another one in its place? No. We need 120v convenience outlets on every lamp post and in many cases they already exist. We simply need the means for EV owners to pre-pay for the electricity so that then they get permission to plug in.

g. Everyone needs to read this document which summarizes BC's experiences and their new recommendations:

Draft Code From Regional Code Council

Code Proposal:

Additional Notes and Documents

Notes from Duane Jonlin

Here's what I learned about the current state of the RCC (Regional Code Collaborative) efforts on EV charging. The RCC developed model code language, which is provided below, and it's up to the individual jurisdictions to implement it.
Snoqualmie is going to adopt the RCC provisions, and Redmond is going to incorporate them into their incentive program. MLT already has the language. Seattle was going to allow for space in the panel but not make any requirements for charging stations or infrastructure until the EV project [a larger EV initiative we're working on this year] concluded at the end of this year and demonstrated that we needed to take further action.

From Don Chandler (VEVA in BC - helped write the EV codes for Vancouver 5 years ago):

This is how VEVA in BC went about getting Vancouver to adopt EV Building Codes:
File:Pulling the Copper.pdf

Some further articles:

Don't get Distracted by "Issues" that only effect 3% of Charging! Almost all of the issues and problems we frequently hear about charging infrastructure apply only to L2 charging. All of these issued vanish with L1 (120v) charging. Few if any issues are involved with just plugging in an EV like plugging in a coffee pot. And many of the outlets already exist!

IEEE National Committee on Transportation and Aerospace

These last two are probably not relevant to Washington State but might be useful?
