J1772(LEAF) vs MagneCharge(EV1)

Tue May 04, 2010 11:31 am

Hello,

I'm curious to the advantages and disadvantages from these two types of chargers/connectors. The MagneCharge from the EV1 or Rav4EV seems to be very easy to use, from this video:

So, why do we need this new J1772? Seems a little harder to insert. Noticed that she hit the top part first, then finally was able to insert the plug.

Oops, this message should go to the general section.

Thanks,

The inductive connector makes a 'transformer' with a coil of wire in the paddle and another in the vehicle-side connector. The transfer isn't 100% efficient so we loose a bit of energy. The waste energy is converted to heat - so the connector must be cooled. Running a pump to cool the connector uses another small bit of energy.

J1772 should be overall smaller (takes less space in the vehicle and paddle storage), simpler (more reliable - less to break), and more efficient.

We'll see if that prediction holds out in 10 years. :D

I don't expect to see this and the J1772 should be a major standard.

Sorry - you lost me. You don't expect to see what?

I agree if you think that J1772 should be around a while. ;)
