Hi there hoping someone can help. As part of my campervan conversion build I want to include an EV hook up as well as shore hook up. The thing is Ive bought the EV (car side male connector) but I'm stumped by the PP and CP connections. I understand that one needs a resistor to link the PE to tell the ev station to send the appropriate amount of power. But in the abscence of anything on the internet I'm left guessing. Yes i can buy a ready made cable but I really like solving these things myself even with limited knowledge of electronics. At this point in time I dont have leisure batteries to charge, I'm just looking for the AC to power my laptop and charge my Makita power tool batteries, if indeed this is possible. I have obviously installed a small MCB consumer unit but the two pins CP and PP act as a go between to let the charge unit know that 1. its plugged in and 2. the appropriate amperage to send down the cable. Anyway if anyone could help I'd be most grateful

thanks

 

What I se as totally unclear is:" I want to include an EV hook up as well as shore hook up." Does that mean a hookup to charge an EV from the camper van? OR does it mean that the camper van IS an EV that will need charging? While an electrician might possibly have some clue about charging an EV from the camper van, that would be only about mains wiring.
IF the camper van IS an EV, then the drive system should have come with the controls package. OR is the camper van an entirely self-designed and built Electric Vehicle of some kind? Or an adaption of the electrical system from some commercial EV?
Without more information you will get nothing but guesses, since none of the participants here seem to be good mind-readers.

AND Julianna is totally correct about charging being a very big deal. The amounts of power are quite large and are able to do lots of damage in just milliseconds.

I thought I was fairly clear I want to use the ac from an ev charge station to power a domestic socket in the van to charge my laptop and other 240v appliances. No where did I say anything about charging an ev car. As I’ve said one can purchase a special fly lead that has a type 2 connector one end and a single three pin domestic socket at the other end. In the lead somewhere is a device that tells the ev charge station that it’s connected. This is the bit I need to make. If this is the wrong forum, just say and I’ll move on.

 

It was not clear to me! But now I see that the desire is for an AC charging connection, NOT the high power DC connection. So what ever plugs into the camper-van will need to connect to standard mains power on the other end. What seems will be the challenge is that most charging stations being built will be for the DC power rapid charging scheme. I am not sure how many of the type 2 charging stations you will find. In addition, it does not seem reasonable that it will be simply a resistor , but rather a 2-way didital communication to gain the billing information, because it is not reasonable that charging will be free. Probably other folks here have additional information.

Think your wrong on that. Other than Tesla the charge inverter is built into the car/EV. And the inverter is what tells the charge line to turn on.

 

Certainly with the HIGH POWER DC chargers there is two-way communication between the power control system/inverter package and the external charger system. But I am guessing that the TS is not considering that connection system to provide AC mains power for internal use. Post #4:" I want to use the ac from an EV charge station to power a domestic socket in the van to charge my laptop and other 240v appliances. "
My thinking is that it will not be likely that there will be many level 1 or level 2 charging positions available, because the much faster level 3 stations will be where the big profit lies.
Levels 1 and 2 may be found in parking lots for employee use, maybe. Certainly any of them available to the public will not be free, nor cheap. And it appears that the TS is considering that kind of charge station. They also probably will have some sort of digital handshake for billing purposes.

Certainly thre process described in that link constitutes a "handshake", but not the kind I was expecting. That communication scheme is more complex than just digital communications, and so there must be some other motivation than just data transfer. The only advantage that I can see is that it would completely prevent the introduction of any sort of malware By means of a non-language communication format.
Functionally it is a language with very few words.

 

Timlaz: sorry, NOTHING was been possible to understands what You want. What is hook, and what is the shore hook. . My solar camper I made just fixing a solar cell string and let the 3 dollar Chinese pseudo-MPPT finder sucks the energy out and transforms it to 12 V car battery. When there is too much sun, the Chinese wonder is disconnecting it, when battery becomes too empty, it automatically switches on. Only thing it afraids as devil from the cross is bad contact in battery. Then the system is de-programming and start to think the board system is half-emptified 24 V. And one case it succeed to load my 12 V battery up to 21 V thus the only way was to utilize it. Thus, for the safety I would reccomend to switch a TWO batteries at series, one for the car, and upper one for kind of douche pump, tap water , electric toilet etc. I have a Fiat Ducato C13. I love that car, it is so large! And eats only 8 liters of fuel. And allows to pull the 3.5 ton wagon. And have blockable differential. etc etc.
