ESVE for older home with 30 amp service

Sat Nov 19, 2016 12:30 pm

I'm looking for a level 2 ESVE charging station. My house has the older 60 amp service entrance with a 30 amp meter. What is the best option? I found this on Amazon: https://www.amazon.com/ClipperCreek-LCS ... 498&sr=8-6

My Nissan Leaf has the 6.6 charger

Clipper Creek makes good EVSEs. You might want to look for a 20 amp unit, though, like a Clipper Creek LCS25.
2013 "Brilliant Silver" SV with Premium Package and no QC, and 2009 Vectrix VX-1 with 18 Leaf cells.

The most offensive, tasteless phrase in use here is "Pulled the trigger." I no longer respond to posts that use it.

Not sure what you mean by a 30a meter if you have a 60a service :? are you talking about a sub meter?
I guess it depends on how much you want to dedicate to your EV charging, Clipper Creek makes a fine EVSE but you purchase them for a specific amperage and cannot change it. In your case I'd think a EVSE where you can adjust the maximum output amperage would be nice. Say your running a lot of power for other things in your house, simply dial down your EVSE. You want to charge at the fastest speed, make sure any other high loads are off in your house and set for 27.5a(max your car will charge at).
EVSEs like the GE Durastation(currently $399 at Amazon) allow you to adjust the output to several levels, although it's not really meant to adjust on the fly or frequently, amperage is adjusted on the circuit board by jumpers, it can be set for 15, 20, 30 or 40a circuits. Other EVSEs like Juicebox or OpenEVSE(start ~$500) allow you to easily adjust maximum output amperage and in the case of the Juicebox it's done using your cell phone and WiFi.
Lastly if your have a '14 or order Leaf and are OK with 20a max then you could simply have your factory EVSE upgraded by EVSEupgrade for ~$300. They also upgrade newer Leafs but they max out at 16a which I'd assume may be too low for you since you were looking at the 24a CC EVSE.
2012 SL purchased used 2/'16
2013 S w/QC purchased new
Juicebox Premium 60a L1/L2 EVSE, Ebusbar 16a L1/L2 EVSE
'12 EVSEupgrade'd 20a L1/L2 EVSE, '13 EVSEupgrade'd adjustable 6-20a L2, 6-13a L1 EVSE
Zencar 13, 20, 30a L1/L2 portable EVSE
GE Durastation 30a

It would be neat to make an Open EVSE with an ammeter measuring the current being drawn by the rest of the house. It can keep adjusting the charging current to keep the total below the service limit.

If you only have a 60 amp service, there's a very good possibility that there simply is not enough spare capacity for you to install an EVSE. The smallest off-the-shelf L2 EVSE is 15 amps, taking up 25% of your available capacity.

I would consult an electrician before buying anything.

This may seem a bit much but I would still go with a 30 amp circuit and 24 amp charging.
Clipper Creek HCS-30 would be perfect.

If you really want to know then turn on everything and measure each circuit with a clamp-on ammeter.
Don't have one? they are inexpensive for just AC so get one.

Do you have?

Electric oven
Double electric oven
electric clothes dryer
electric water heat
electric furnace
Air conditioner, how many tons?
Anything else big? (240v)
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV

Great advice. I recommend a 20 amp circuit with the following:

Go-Cable

http://shop.quickchargepower.com/Go-Cab ... n-GC20.htm

$299 from Quick Charge Power

Go-Cable(tm) is the super flexible and super lightweight low cost 240 volt / 20 amp portable charge cable (EVSE) for your EV sold in North America or Japan.

Full 25 foot cable length !!!

Requires a 208- 240 volt wall outlet, with a minimum 20 amp circuit.

Provides up to 3.8kW of power to your EV.

Equipped with NEMA L6-20P wall plug.

Optional adaptors for $29 each:

NEMA 14-50P (RV parks... this is the home outlet recommended by Tesla)

NEMA 10-30P (older dyers)

NOTE: the NEMA 14-50P can be modified to be safely used with NEMA 14-20P or NEMA 14-30P (newer dryers) by removing the neutral pin. Any qualified electrician can do this.

Other popular plugs available via special order.

The maximum charge power:

16 amps or less (3.8kW at 240 volts):

Nissan LEAF (2011-2012), Chevy Volt, Chevy Spark EV, Toyota Prius Plug-In, Ford C-Max Energy, Ford Fusion Energy, ZERO motorcycle (2015 and newer with J1772), Brammo motorcycle, Smart Electric Drive, Ford C-Max Energi, Karma Fisker, Mitsubishi iMiev, Cadillac ELR, Porshe Cayenne S-E, Porsche Panamera S-E, Honda Accord Plug-In.

30amps or less (7.2kW at 240 volts):

Nissan LEAF (2013 and newer at 28 amps, however some are 16 amps), VW eGolf, Kia Soul EV, BMW i3 and i8, Ford Focus Electric, Fiat 500e, Honda Fit EV, Fiat 500e.

40 amps or less (9.6kW at 240 volts):

Tesla Model S, plus the following two Tesla powered cars; Mercedes B-Class ED and 2012-2014 Toyota RAV4 EV

48 amps or less (11.5kW at 240 volts):

Tesla Model S (2016 and newer)
Tesla Model X
Tesla Model 3

70 amps or less (16.8kW at 240 volts):

Tesla Roadster (requires firmware update to use any charge station over 70 amps)

72 amps or less (17.3kW at 240 volts):

Tesla Model X and Model 3 with optional 72 amp charger

80 amps or less (19.2kW at 240 volts):

Tesla Model S with optional "twin chargers" (2012-2015)

You can get a system from Brultech to measure the circuits in your house. This is the lesser system, the ECM-1240, although for more circuits they have the Green Eye Monitor (GEM) but it is significantly more expensive.
http://www.brultech.com/store/category.php?id_category=16

I am on a demand rate from my local electric company, because they are requiring all people with PV solar to be on this rate, and the Brultech (I have the GEM) shows what the house is either using or exporting. The system I have hasn't exactly been "plug-and-play" but I have gotten it working after some effort. I will say that in my house I have seen 15kw (>60 amp @ 240V) on a few occasions, but in general it is possible to keep things at 30 amps or less, mainly with determining the proper time when the dryer can be run. I'm not a certified electrician, but I believe with the Brultech data you can meet NEC rules by showing usage for a number of months, and then be allowed to legally install the extra circuit in the panel. But once again, a certified electrician could tell you more details, and with a 60 amp service you definitely want to follow code.

Switch the stove or dryer to gas, and it would free up enough for a circuit too, although a home with a 60 amp service entrance probably doesn't have an electric stove or dryer.

Most people are fine with 240V 16A EVSE. Leaf will fully recharge during the night.
If you have the possibility to get 60A for the whole house (like changing the meter)
you might prefer 30A charging rate IF you have no ChaDeMo stations near you.
I do have ChaDeMo available and only use 16A EVSE. Sometimes I do visit DC-charger,
but that is only 1-3 per month. I'm a heavy user, 20 000 miles per year.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

location location location!!
where are you? In WA State? PSE Customer?

I am in the EXACT same position as you and you might want to go straight to clipper creeks website because they have many more options. I got the same as yours except with an L6-30 p plug (the more likely plug you would have installed at an older home) Ordered it Tues, it arrived yesterday.

my cost after PSE Rebate, fed tax credit, etc. shipping, about minus $120
