Re: [EVDL] AVCON INLET NEEDED

My apologyze i didn't had seen this picture and known you had the same
system...
for me this is acceptable as on our cars, when car is closed you can't open
charging door but you are right when it's unlocked you can manually act as
if your hand was the plug...
same as putting cisors in wall plug imho but yes it's possible...this didn't
significate system is not sure, just you can always suicide yourself if you
really want to ;^)

Re: [EVDL] AVCON INLET NEEDED

Dear All,

Cor's "Avcon" connection is very much a hand-modified set-up: maybe not a
"one-off" but I haven't seen it anywhere else other than that particular
model for a V2G application, since the bi-directional three-phase transfer
is higher powered than anything that the Avcon/Mar=E9chal systems were
designed to handle! It is otherwise the standard European Mar=E9chal
connector but with what would be the earth pin replaced by the third
rectangular contact (and the earth where the neutral would be?)

The (standard) Euro version was given 4 AC connections for a 230V (220-240V)
single phase or 400V three-phase connection, matching the normal supplies
found in most of Europe. The other similar terminals (A,G,K,L) are for the
connector presence detection, signal ground, and 2 for serial comms
respectively (although PSA cars never used the L line, it is provided since
the protocol otherwise follows a similar standard as for OBD diagnostic
connections) The AC and signal terminals are rated at 20A. The earth
terminal is larger which I think is the same size as used for the
single-phase AC connections on the STANDARD US Avcon version for 32A
single-phase ONLY since three-phase is less commonly available. The two
large rectangular contacts are the DC "bus." The US and Euro versions are
similar but not incompatible!

In Europe an AC-only connector can be wired with neutral and three phases
and a vehicle will take just single-phase if that is all it can use.
Three-phase can give up to 14kW. [Note: Three-phase with neutral supplies
via a socket are hard to find in the UK compared to other parts of Europe.
Socketed three-phase (without neutral) anywhere is scarce, usually favouring
hard-wiring of pumps, vehicle lifts etc.]

The connector supplied with most vehicles has just Neutral, Phase, Earth, A
and G. A-G are linked to provide the "connector present" signal to the
vehicle as the start inhibit. Cables for use with the French public
charging points (that originally used a plug/socket compatible with the
domestic standard) incorporated an extra pilot core via a diode and resistor
connected to A/G in the Mar=E9chal handle and had an earthed braided screen.
Most other countries replaced this cable with standard H07-RNF neoprene
sheathed, rubber insulated cable [ed: screened cable should have been
adopted as standard IMHO]

When using the off-board rapid chargers, the vehicle basically controls the
off-board hardware much as if it were onboard. Real world chargers
reportedly take quite a while to start the charge process.

The Mar=E9chal inlet CAN (easily) be defeated by hand to expose the termina=
ls:
I think that it is a failing of the vehicle designers that the DC terminals
are wired directly to the DC bus without using a contactor. The fact that
you can defeat it "without the use of a tool" is a basic "standards"
failing! The centrally locked flap is really not a sufficient "barrier."
But as Philippe says anyone who really wants to commit suicide with a
vehicle, even someone else's, will find a way!

Not all the PSA (Peugeot/Citroen) EVs did use the DC connections. There are
a few cars out there (maybe exclusively some Citroen Saxo models) that
don't, probably as part of a budget spec model, probably for fleet customers
where the vehicles would never be expected to use rapid charging. Not sure
if the inlets had the DC terminals or not, but the heavy single-core DC
cabling from the inlet to the Sagem electronics box across the top of the
battery case is omitted. Popping the bonnet to look for the cables is the
definitive way to tell if the car is rapid charge capable or not (but there
is also a "rapid charge capable" sticker on the inside of the inlet flap!)

The inlets and connectors are still available today (I can supply) in a
variety of configurations so the fewer terminals, the cheaper they are.
"Logically" the ECU that controls the off-board charge process is separate
but in practice was likely always "physically" part of the vehicle ECU, so a
vehicle without the rapid charge wiring could most likely be upgraded by
retrofitting the "full" inlet and wiring (the inlets were filled with
compound making piece-meal repair/upgrade difficult.

I decided to buy some of these for spares, but sadly they don't have
them in stock, despite that listing being up there for years.

If anyone has one that they don't need or knows where else they can be
found, please drop me a line!

Re: [EVDL] AVCON INLET NEEDED

I just got my new US inlet this week from AVCON.

Re: [EVDL] AVCON INLET NEEDED

Evan,

I have just received the new price list from Mar=E9chal: the Euro-spec inl=
ets
(for the vehicles) start from around =A375+VAT+handling (US$150) and the
connectors (for the charging cable) start from around =A384+VAT+handling
(US$170) depending on which terminals you require.

Kind regards,

Matt

Re: [EVDL] AVCON INLET NEEDED

Evan,

Just to clarify, these are my prices based on the TRADE prices as supplied
to me! I am putting together an order in the near future, so if you "want
in" for a better price, let me know.

I am just waiting for them to get back to me on a price for the unlisted
"normal" handle (as opposed to the insanely expensive rapid charge handle)
with single-phase AC + 50A DC terminals, for convenient semi-quick charging
from a variety of AC supplies.

(BTW, the rogue '?' in the previous posting were the Pound symbol, should
have used GBP)

Kind regards,

Matt
