No, it's 120V +/- 5% at the Service Entrance, i.e. at the meter.

The power company is NOT responsible for your house wiring, especially not
for looses in the house wiring.

It just isn't an issue Bob; firstly you can't touch live parts.  Even
if you can, almost all sockets (certainly all outside ones) are on
RCDs (GFCIs).  Because the voltage is higher, you *have* to have more
respect for it.

Anyway, we're talking about the Tesla's garage charger, which is 240V
in any case.

> >  Yeah, ya can with almost any plug.120 volts here will be safer than 240.

The UK and Euro-Schucko sockets are shuttered and the plugs have
touch-proof pins.   So  you really can't touch the live bits, even if
you try quite hard.  That's the point, and that's why it's perfectly
safe at 230V.

They're supposed to be out in the Spring aren't they?  To my mind it's
a sensible plug, even if only for the fact that it forces a proper
electrical installation for charging at the owners home.

It's what, $100 worth of parts for the fancy box with GFCI and bit of
protective circuitry, on a $90,000 car.  They'd be mad if they didn't.

Yes; that is a shortcoming, a consequence of continuing to use designs
that are nearly 100 years ago.

The British outlets I've seen are very similar -- except that they
mount them below the surface in a hole deep enough so the mating plug's 
body blocks access to the pins as you insert/remove it.

There are US plugs and receptacles built exactly like this; but the
standards don't require them, so most people don't install them. The
bottom line is that the problem isn't considered serious enough to
bother to address.

It might; there are product liability lawyers that would no doubt try. 
:-( But it is by no means a sure thing. I suppose it's a cost/RISK 
analysis that's needed.

Most companies look at what others in related industries have been 
doing, and then do something that is at least as good as the "generally 
accepted practice". If you're wrong, then everyone else in the industry 
must have been wrong, too. This greatly reduces the odds you having to 
pay some ruinous penalty from some jury being swayed by crying widows or 
maimed children.

For example: Toasters have exposed metal parts, they don't have 3-wire 
grounded cords, and there is no interlock to keep you from sticking your 
hand inside and getting burned or shocked. Every year, dozens of fires 
and shocks are reported. Yet nothing is done about it. There are no 
ruinous lawsuits, they don't tighten the standards, and toasters keep 
getting built the same old way. Why?

It's because people are used to the situation. Companies building new 
toasters just copy what all the previous toaster manufacturers did. If 
they're dragged into court, they say, "It's in the standards! They're 
all built that way! Everybody knows toasters can be dangerous if used 
wrong! How can we be blamed?" And the jury agrees, and finds them innocent.

Charging electric cars is no different from plugging in any other 
electrical appliance. People have been doing it forever -- it's nothing 
new. Consumers have been using high-power plugs on air conditioners, 
boat marinas, RV parks, stoves, dryers, and all sorts of things.

Inexperience people don't know what's been done before, or how it turned 
out. Their solutions tend to miss the target -- either far too simple, 
or way too complicated. It leads them to invent their own standards, 
because they don't know what's already "out there" in the field.

I think this was the case with the GM Magnecharger, and now with the 
proposed Tesla standard. Both are overly complicated, expensive and look 
naive and inexperienced to anyone outside the company. Neither will set 
any kind of long-term standard, because no one will find them worth copying.

2-phase and 3-phase (and in fact, all other numbers of phases except 
single-phase) have the advantage that the instantaneous sum of the power 
is a constant. This means the power produced by a generator or used by a 
motor is constant -- no torque pulsations.

2-phase happens to need 4 wires. They are symmetrical around ground; you 
can have a 5th neutral wire if desired. A 2-phase motor is more 
complicated than a single-phase, but less complicated than 3-phase. This 
is the attraction as far as the motor designer is concerned.

3-phase only need 3 wires -- that's the advantage as far as the power 
company is concerned (fewer wire to route). The total wire size for a 
given amount of power is still the same; it's just split into 3 parts 
instead of 4 parts (so you don't save any copper). The higher the phase 
count, the more complicated the motor is to wind.

Now, all of the above assumes sine waves. If you have square wave power 
(like from an inverter), then the more phases you have, the smoother the 
power. 4, 6, 12, and even 24 phase systems have been built.

Hi Roland,

I'm hoping you can elaborate on your small under the dash heaters?
I'm wondering what's the brand and model, and also how you hooked them
up (electrically and mechanically.)

I was about to buy one of the $600 water type EV heaters, but today
(at 35F outside) I noticed that pretty much only my feet and legs get
cold on my half hour drive to work.  If its really cold I have a 12V
heated blanket but that makes it awkward to drive, and my feet still
are cold.  Maybe all I need here in NC is one of these little guys
under the dash at my feet.

thanks very much - De

Actually, you misread. Evan T said the above, and Lee said the rest; no 
revision or variance in Lee's stance. ;^>

Firefly Energy has issued some more information on the release of their new 
lead-graphite acid battery.
 
http://www.fireflyenergy.com/images/stories/pdfs/PressReleases/FireflyEnergyUnveilsOasisTruckBattery102907.pdf
 
Also a blurb at Green Car Congress.
 
They say that the battery will be available for testing and review in Q1 of 
2008.  I assume that this testing will be done at a limited number of 
facilities, rather than being available for testing by the general public.
 
They also mention initial availability in the summer of 2008, with full 
production by the end of 2008.  Does this mean that these will be available for 
purchase as early as next summer?  Anyone with further insider information on 
actual availability to the public?

Not sure if these would put out enough heat, even here
in the South.

I've read reviews of those heaters, that plug into the 12v socket.
Most everyone said they threw them away.  A friend of mine bought one
when his car heat went out, and he said he could only feel the heat
when he stuck the thing inside his coat.  I think he threw his out
too... I'm hoping there are small heaters that are more substantial
than that :-)

Hello Deanne,

The ones I have are made by Phillips. I think KAT's may make some like 
these.  KAT's and Phillips can be purchase through a auto parts store.  I am 
using a 640 watt at 120 volts 60 hz on the driver side, which all last 
winter here in Montana is the only heater I use so far.

It is all self contain with fan and has a built in thermostat with a U 
bracket for hanging under the dash.

My input AC power to the EV is a 50 amp 120/240 volt 4 wire plug that is 
connected to a terminal strip with four wires, which are the two line wires, 
(L1 and L2 which reads 240 volts between these wires), a neutral wire, (N) 
and a ground wire (G).

120 volts is tap off L1, Neutral and ground to a onboard chassis mounted 
circuit breakers.  These are the same type of circuit breakers that are in a 
circuit breaker panel, but you install a circuit breaker chassis mounts that 
is clip onto the bottom of these plug in circuit breakers and can mount them 
on a metal chassis plate. You can get these circuit breaker mounting clips 
from any electrical supply house.

A No. 10 AWG type MTW 19 stranded copper wire feeder circuit is ran from the 
circuit breakers and terminate at a 300 volt rated terminal strips that is 
place under a fold down dash panels and place on a metal chassis plate that 
is mounted on stand offs which extends the chassis plate off the firewall 
about 3 inches.

MTW wire is a softer chassis wire that lays better and has thicker 
insulation than THHN that has a thinner insulation that requires a jacket or 
conduit.  If you cannot find 300 or 600 volt rated MTW wire, then it is best 
to use a 3 wire power cord with insulation and a jacket that is rated for at 
least 300 volts.

After exposing about 4 inches of wire from the jacket, install a heat shrink 
to seal the wire to jacket connection.

I than connect A No. 12 AWG type MTW Line wire from this terminal strip to a 
on dash 30 amp 250 vac 3-position selector switch that either can connect 
the heater unit to the incoming AC power or from a on board DC-AC 5kw 
inverter unit.

Connect from the center position of the selector switch to another terminal 
point of the terminal strip, then you can connect your heater cord (with the 
plug cut off or make a plug into a connector that is wire to the that 
terminal point.

My Delco 145 amp 13.5 to 15 volt alternator and a 135 AH Trojan 12 volt deep 
cycle battery provides power to 120 Vac 60 hz 5kw inverter.

The advantage I have with these system, is when I am coasting down a hill, 
the alternator is still providing power to the heating unit, while the main 
motor ampere and battery ampere is setting at 0 amps.

I use to have a on board Honeywell motor generator that provide the DC-AC 
power to the heating systems, power steering, and power brakes, but it was 
using battery ampere full time and did not provide me with any mechanical 
REGEN which I needed to slow this EV down while going down long icy hills.

This system has the same effect as compression braking of a ICE when I apply 
as much load as I can on the alternator 12 volt circuits and inverter 120 
volt circuits.

No, The underdash heater units I am using are metal case and hard wire in. 
They require 640 watts at 5.33 amps at 120 volts or 53.3 amps at 12 volts 
through a inverter.  You need a heavy depth cycle battery and a alternator 
to run these units.

The larger one shown may work which is about 12v x 13a = about 156 watts. 
It may work, if you preheat with a 12 volt battery charge on for about 60 
minutes before you leave.

Isn't it more like fully obsolete by end of 2008?
they compare themselves with a 200cycle life but without stating a value 
for themselves which to me suggests its only marginally better. so 
unless they plan to be super cheap I'm not sure how they could compare 
favorably to 2009 lithiums
