Re: 40A 9.6kW Deluxe OpenEVSE waterproof outdoor unit For Sa

The L2 EVSE and the LEAF's internal charger limits the power into the Battery Pack
when doing L2 charging. The heating just uses energy from the Battery Pack,
independent of the charging process. Since a Chademo QC (some call it L3)
charging session can add energy to the Battery Pack a LOT faster, any energy
being used for heating (while QC is in progress) is a smaller fraction of the
incoming (charging) energy, and essentially goes directly from the QC to
the heater, with less going into the Battery Pack.

It is possible that the QC controller in the LEAF is monitoring the current
going into the Battery Pack, and it could request more current from the
QC device, to make up for current used by the heater. This might vary
between model years, and in different firmware versions. Apparently,
you observed this happening ... in what year LEAF?

In my 2013 LEAF. unfortunately the QC package (L3) hasn't done any good in the Vally. we have no working chademo chargers here. the one at Sahara Nissan has been broke for like a year and was removed from charge points App. the ones on water street in Henderson never got opened. they can be seen on the plug share app.

Yes, absolutely! MNL is still not getting email notifications out when a member PM's me, others have reported the same. Someone said it was a Hotmail problem, I believe it as Gm-Volt forum has intermittently had the same issue. I would love to build you your own custom EVSE. You can email me directly at bsaelectronics@hotmail.com Check our my PDF catalog and website at the links below.
