A real wall box should know the power capability of the power source (depending on your energy contract, building power consumption and photovoltaic power generation) and dynamically change the recharge current. With smart grids, also maximum power available from the energy provider will dynamically change during the day.

This sophisticated mode is not mandatory I presume.
What about leaving the user to determine what are the possibilities for feeding the wattage to the car ?

Here is a picture of the 1st prototype of my 30A mode2 charging cable (CRO).
It's the first one available that can manage a settable current from 6A to 30A. It has internal breaking capability (both phase and neutral), overcurrent (30A) and residual current protections (30mA).
The case is in strong polycarbonate (not standard ABS), the cable is oil and flame repellent, custom made.
It's available at the same price with type 1 (in the photo) or type 2 female connector, with 5m (400€) or 10m cable (440€).
I'm testing it on available cars in the market, it will be checked on a Zoe as soon as I will get one to test.



The industrial power plug can manage 32A continuous, current limited adaptors are available with 16A industrial or 10A domestic Schuko. Their price is 40€ each. Use of standard adaptors is discouraged because they are not current limited and are for temporary use only.

If you install a 32A interlocked industrial power inlet in your garage, this can substitute a 32A monophase wallbox. You can find it in any electrical store at about 50€ (we can provide it at the same price, too). Like all powers inlet in your home it must be protected with a suitable overcurrent + residual current device, I suggest a dedicated 32A overcurrent + 30mA residual current breaker (~50€).



Now I'm testing prototype and assemblying a 10 pcs preserie, mass production will begin in March.

No, but these are the advantages of a real wall box. Otherwise, they are simple mode 2 CRO fixed to the wall (and without the car cable). They should be cheaper than a CRO.

I think this is the minimum requirement, I would never buy a device unable at least to regulate the current.

I don't think to know the power capability of the power source is necessary. People don't often change the energy contract and people who set up photovoltaic panel sell the electricity to EDF in FRANCE. In the smart grids (Réseau électrique Intelligent) the interest is EDF could stop or start the recharge according to energy production.

Davide R could you explain me how the CRO communicate with the EV car ?

In France you have a lot of electrical power at low price, in Europe the story is different.
Standard energy contracts in Italy are 3kW max, optional for residential contracts is 6kW monophase. To get an higher power limit is very expensive, normally only industries have 3-phase (monophase contracts are limited to 6kW). We pay 0.23€/kWh, about double than France.
With 3kW limit, may be very important to have a wall box that knows the power consumption and regulates charging current to avoid exceeding the maximum power limit.
In the next future nuclear source availability will decrease like petrol, so all people should optimize energy consumption.
Rapid diffusion of electric cars will generate a big energy request, so the energy distribution network will not be able to manage the full load, and smart grids will not be an option.

This is defined by the J1772 standard. All cars agree to this standard.
In the car connectors there are 2 dedicated signals:
- PP signal codifies the maximum current that the cable can manage, with a fixed resistor.
- CP signal is a bidirectional signal: the infrastructure signals to the car the maximum allowed current (with a PWM signal), and the car signals its status by connecting a different load resistor.

Thanks you for those informations. I understand your point of view in the future the energy will become rare and expensive.
Your charging cable is very interesting but if people want used that at home, they'll have to have a dedicated socket like Green up access (http://www.legrand.fr/ecat_france/090471-prise-green-up-access-3-2-kva.html) and not to exceed 16 A for the security.

Great!

Good luck in march for your product!

It's better to install a 16A (or 32A) industrial: it's cheaper and stronger, and for occasional use you can convert to Schuko with a simple (5€) adapter.
Mechanical interlock is good to avoid unplugging while high current is flowing, that can damage the inlet: when you insert or remove the plug and when the plug is not inserted power is not applied.
For this reason my Schuko adapter is 10A limited (it's strong, it could handle 16A continuous without problems), to connect to any domestic inlet
But you must pay attention (like any CRO with Schuko) to not remove the Schuko connector while recharging. You have an on/off button on the control box.

Très interessant ce CRO Mennekes réglable:

Le revendeur alsacien de ce câble assure que le câble Sobem Scame est certifié ZE Ready. Est-ce que quelqu'un peut confirmer avec un document officiel ? Sinon, je lui demande.

Sinon, il a indiqué que ce câble, pour l'instant au tarif de 1500 € pourra chuter aux alentours de 600 € en fonction du volume.

Belle trouvaille Ecovip !
LA question: sera t il compatible en fonctionnement sur Zoé ?

Les 2 câbles (Sobem et Mennekes) sont compatibles avec la Zoé mais je ne sais pas s'ils sont certifiés Renault ZE.

400 € + VAT

10A and 16A (16A with schuko.... dangerous??)

It seems worst than David R cable.

This cable and David's cable are two examples of real cost. Materials not cost more than 300 €.

Alors "Carlos", celui là est il "ZE Ready"....???

Frank57 a écrit:Alors "Carlos", celui là est il "ZE Ready"....???

Non.

Déjà pas la bonne prise et câble fait soit même en partant du kit open evse.

Il y a quelque chose que je ne comprends pas très bien.

Comment un site peut proposer un cable à 250 euros (Ratio electric) : http://www.ratio.nl/files/Prijslijst%20EV.pdf

Et un autre à 1400 euros ! (electric cars) : http://electric-cars-france.com/bornes__syst%C3%A8mes_de_recharges/c%C3%A2bles_de_recharge_pour_v%C3%A9hicules

Que justifie cette différence ENORME ? La certification Z.E Ready ?

793 euros !! aaaaah ben là ca devient intéressant ! moitié prix de celui de Mennekes. (et dispo de suite apparemment..)

C'est la même base que le Sobem Scame on dirait, avec un prix à peu près normal...
