Er det mulig å bytte kontakten/pluggen i bilen til en med  J1772 standard?

Er jo så mange fine ladekabler/stasjoner/poder å få med denne pluggen, og det kommer kanskje som standard på flere ladeplasser etterhvert?

Noen som har prøvd?

[hma]

Har ikke prøvd, men pilotsignalet fra PCS'en til Think (kladden) følger samme standard som øvrige elbiler.
Det skal derfor være en grei sak rent teknisk.

Th!nk i USA har J1772 kontakten, så det lar seg gjøre.

I Norge er "proximity switch" en magnetbryter, mens den er en elektrisk forbindelse gjennom kontaktene tror jeg i USA. Noen i USA sier at proximity switch ikke fungerer på deres Th!nk. Det kan virke som om det er en programmeringssak i PCU, men jeg er ikke sikker på det heller.

J1772 har ekstra pinne og bryter i pistolen, disse bruker du istedet for magnetbryteren.

Har tenkt på å bytte ut selv, men har ikke rukket det enda....

Da har jeg sammenlignet pilotsignalet på Leaf og Think, de er ganske lik på 10A og 16A. Men det er en vesentlig forskjell: når Leafen ikke er tilkoblet står det konstant 12V på pinnen, mens det på Thinken fortsatt går pilotsignal på 1000Hz men da med topp på 12V istedet for 6V som det er under lading.
Leafen stemmer med standarden: http://code.google.com/p/open-evse/wiki/J1772Basics

I standarden står det "pilot signal low" skal være -12V, det stemmer ikke da det er 0V målt mot gods.

Så da spørs det om det går bra å bruke kablene om hverandre???

Husk at enkelte bruker + og - som betegnelser for poler på batteriet, så et 12V-batteri har da en -12V-pol og en +12V-pol, som så bli hhv -12V og +12V.

Om denne sjøsyke betegnelsen brukes i dokumentet du refererer til vet jeg ikke, men jeg har dessverre sett den brukt alt for ofte av folk som mener det er 12V mellom -12 og +12!

Jeg bruker nå i alle fall de samme ladestasjonene på Think som på Leaf og andre J1772 biler.

På f.eks disse stasjonene bytter jeg bare om på støpselet, så lader Think helt fint. http://elbilhjelpen.no/htm/deler.html#Semiportabel

[Lynet]

Think har en reedbryter som registrerer at pluggen er satt i, den sluttes når pluggen settes inn, da lyser lampa og PCU har fått signal.
J1772 sin bryter sluttes når knappen på pistolen trykkes inn, da skal ladingen stoppe.

Det du skriver elektrolux at ved å skifte støpsel så viker det Think bekrefter at pilotsignalet funker. Men hvordan skal man løse det med reedbryter/håndtakbryter hvis man setter på J1772 på Thinken?

Regarding the pilot signal:
According to the many versions of the J1772 the EVSE (or PCS) is generating 1kHz square wave with variable duty cycle. This square wave has a variable amplitude that means different things.

This square wave will change during connection and charging in couple of different ways:

(1) The connected vehicle will change the positive side of the amplitude via diode and resistor and in this way "tell" the EVSE to change state. So for example if the vehicle is charging it will connect the pilot line to ground via resistor 882Ohms resister and diode and thus effectively lowering the positive side of the amplitude to +6V.
As Lynet pointed before - here are some details:
http://code.google.com/p/open-evse/wiki/J1772Basics

(2) The EVSE (or PCS) may vary the pilot signals duty cycle and thus indicate to the vehicle the maximum current available for charging.
For example a 20% duty cycle (20% of the wave is at +6V, 80% of wave is at -12V) indicates 12A max current available to the vehicle.

Regarding the proximity switch:
One of the pins in the J1772 vehicle inlet is a "proximity" pin. What this means is that if this pin is connected to ground the vehicle thinks that there is a plug connected to the inlet.
In some (most?) vehicles - if this pin is disconnected from ground during charging the vehicle will stop the charging. Notice that this is all in the plug handle - there is usually no "proximity" wire going to the EVSE (or PCS). When the vehicle stops charging it will remove the resistance on the pilot signal and thus indicate to the EVSE that "I am disconnected and not charging anymore".

Back to Think
I think we need answers to the following questions to be able to conclude how compatible the car is and what are the chances of been able to charge the car on different J1772 EVSEs:
- does the vehicle change the resistance on the pilot signal to indicate changes in state (charging, etc)?
- does the vehicle reduce current if the duty cycle of the pilot signal is changed during charge. And if yes, how long does it take to comply?
- does the vehicle stop charging if the proximity pin is not connected to ground? Apparently there is a proximity line since we see the plug light up if the PCS is connected. Are there differences in versions of the cars?

Cannot say this for sure, but I think I remember seeing 24V pilot signal from the original Think cable, while mine have only 12V pilot signal. Anyway this does not seam to matter, and car charges fine also from my 12V cable. I am pretty sure the Think loads the signal like other cars do, but have not seen this first hand.

- does the vehicle reduce current if the duty cycle of the pilot signal is changed during charge. And if yes, how long does it take to comply?

Yes it does, and it takes 3-5 sec to change current.

- does the vehicle stop charging if the proximity pin is not connected to ground? Apparently there is a proximity line since we see the plug light up if the PCS is connected. Are there differences in versions of the cars?

Can not say, as this is build into the plug itself.

Ok, I did some looking... assuming the electrical part of J1772 holds, how about the physical part?

See the screenshot:
- What is the length of the cable from the car inlet to the distribution box (is it a distribution box?)? Are there different lengths depending on generation?
- What is the connector on the distribution box? Or is it just crimped cables?
- Where can I find a photo of the inside of that box?
- What is the configuration of the mounting holes of the current inlet?

I will try to answer these when I have a chance to examine the car, maybe someone has the answers already?

I think screenshot (from the Sparepart Catalogue) is displaying the High Voltage Harness for gen2-PCU, which is different from gen1.
I have not examined the parts in my gen1-car in details, but if I don't remeber wrong, the inletcable is going directly to the back of the car - under lid covering the softstarter - and is terminated in a connector box.
I guess the cable harness from the outlet to this box is about 3 meters.

[Lynet]

Tror nok det går via en koblingsboks foran hma, det er kun AC som går bak. Hverken reedbryter eller pilotsignalledningen går bak. Men de kan selvfølgelig være splittet ved kontakten.

Det som er merkelig er at fabrikken ikke har tegnet inn softstarteren og skilletrafoen i koplingsskjemaet for gen1.

[BauDemo]

I need a possibility to charge a Think from the new J1772 charging boxes, and after considering the effort needed to retrofit J1772 charging inlet I decided to make an adapter instead. A J1772 inlet to Think Style plug.
I have ordered all the parts and will be testing it sometime next week.

Anyone interested?

[jahnarne]

Depends a bit on the price of course, but in theory, yes
