Listen. I expressed my opinion in what I believe in my mind is a fair use of a shared resource. You go on and on about installing L2 and such. This is nothing to do about L2 or L1. If I were you, I would put a timer in my Leaf so that it is always charging at my lowest tier in my home (on some 110 plug), which I believe is at night and so is very convenient.
Yes, you expressed an opinion that isn't based upon the facts of my situation nor upon common sense if you were at my work w/similar working hours. The L2 was in reference to someone else's response here.
I guess you don't understand how tiers work and TOU plans work here. Look at http://www.pge.com/tariffs/tm2/pdf/ELEC_SCHEDS_E-6.pdf" onclick="window.open(this.href);return false;, page 2 and http://www.pge.com/en/myhome/saveenergymoney/plans/tou/index.page" onclick="window.open(this.href);return false;. The values for baseline usage, 101% to 130% of baseline, 131% to 200% of baseline, etc. represent tier 1, tier 2 thru 5.
If I ventured into tier 3, even though it's off-peak in the middle of the night in "summer", the marginal cost is 28.6 cents/kWh. It rises to 32.6 cents for tier 4 and above. Oh, and it screws me for the other two time bands: peak and partial peak (see page 4 for definitions). Look at those rates!
Judging by my typical current home usages, which include occasional Leaf charging @ home on weekends, I'm almost always within tier 1. If I look at Carwings numbers, taking into account approximate charging losses @ 120 volts, charging ONLY at home would push me into tier 3 virtually every month and possibly tier 4, some months. Seems pretty dumb to do that for no reason other than a few guys at MNL telling me I should.
Please post some of your summer and winter monthly kWh usages and costs w/your utility (including taxes and fees). I will only be able to calculate PG&E cost based upon the E-1 schedule (non-TOU based at http://www.pge.com/tariffs/tm2/pdf/ELEC_SCHEDS_E-1.pdf" onclick="window.open(this.href);return false
. You'll see what I mean by the baselines and tiers being horrific for many.
And per my post at http://www.mynissanleaf.com/viewtopic.php?p=379033#p379033" onclick="window.open(this.href);return false;:
Per http://www.pge.com/baseline/" onclick="window.open(this.href);return false;:
Determining Baseline Quantities
Service territories are divided into climate zones that reflect energy consumption needs. Each zone, or "rate schedule," is allocated a daily quantity of kilowatthours (kwh) of electric power and therms of natural gas that can be billed at a lower, "baseline" rate.
The Public Utilities (PU) Code establishes baseline quantities for average residential gas and electricity use within each baseline territory. The PU code specifically requires that baseline quanties fall between 50 and 60 percent of average use for basic-electric customers in both the summer and winter and for all-electric and gas customer in the summer. The PU code also requires that baseline quantities fall between 60 to 70 percent of average use for all-electric and gas customers in the winter
So, in summer, an "average" customer would already be at the upper end of tier 3 or the boundary of tier 3 and 4.
My summer daily baseline allotment is only 11.0 kWh/day, so that's 330 kWh/month assuming 30 days/month.

At this time you have more chargers than EVs and there is no resource contention. Which is great.
Nope. I just did a count of EVs + PHEVs on our internal "voluntary" list for those who use the self-service EVSEs. There were 58 cars. Not all of them are driven to work everyday and not all of them charge everyday. Probably 1/3 to 1/2 of the drivers elect to use the EV valets.
Serving the 3 adjacent buildings, there are only 8 self-service J1772 handles. There are another 6 for EV valets only (our cards don't work on them).
There are I believe 2 J1772 handles in a totally separate area (different building) maybe a mile away. I don't ever use those or go there.
There are 7 120 volt outlets designated ok for PHEV/EV charging.
mkjayakumar said:
But that will change at some point, and I hope your charging habits also change then.
Maybe on the first point and how much it changes will depend on what the contention patterns look like. I of course will yield and leave spots open to people who actually need the charge to make it home.
As I said, when I use the L2s, I usually start late, when there plenty of open J1772 handles and EV spaces when virtually everyone else is done charging.
I've spoken to another Leaf driver who does charge at work and has a much shorter commute than me (mine's ~12 miles each way).

Re Tesla: If I were to have a BEV with 200+ miles and my round-trip commute is only 50 miles, I don't see any reason why I should typically charge in office.
FWIW, 6 vehicles on our voluntary list are Model S. I know some of them do charge at my work. Two are Signature Red color (per their info) which means they got the 85 kWh Signature editions (very early units). Another recent addition was a P85+, also 85 kWh. I don't know about the others. One of those Tesla Model S Signature owners lives only 7 miles from work. I don't know how often he charges at work, but I know he's done so.
Today, when I looked out the window at the EV valet area, I saw 3 Model S charging.

Just wondering if you bring your own ketchup to a fast food place or soda/pop/ drinks to a meal away from home. yes its off topic
Something more analogous to my situation: some companies (like mine) provide a free lunch, drinks (e.g. coffee, soda, juice, tea, bottled water, etc.), some snacks and fruit. Should we all bring our own lunches, snacks and drinks to work instead?
