My REMA on my Blink home EVSE is bad. Below are my temperature measurements I made of the REMA, Yazaki and ITT plugs while charging my 2011 Nissan Leaf.
Note, temperatures measurements were measured with a CEN-TECH IR Thermometer Item # 93983 running in “MAX” mode ½ inch from the socket or plug.
All measurements made after 40 minutes of charging:
Panasonic (Nissan) upgraded by EVSE Upgraded to 16 Amp. EV cord set that comes with the Leaf.
Yazaki Plug
11.7 °C ambient temperature next to plug & inlet.
15.6 °C AC Power L1, delta T = 3.9 °C
14.5 °C AC Power L2, delta T = 2.8 °C
Leaf Inlet
15.8 °C AC Power L1, delta T = 4.1 °C
15.4 °C AC Power L2, delta T = 3.7 °C
======================================================================
The next plugs and inlet were on a SAE J1772 extender I made connected to 16 Amp. Panasonic EVSE above so the current was the same, 16 Amps.
ITT Plug
8.4 °C ambient temperature next to plug & inlet.
11.1 °C AC Power L1, delta T = 2.7 °C
11. 1 °C AC Power L1, delta T = 2.7 °C
Red Point Engineering Inlet
8.4 °C ambient temperature next to plug & inlet.
11.0 °C AC Power L1, delta T = 2.6 °C
10.8 °C AC Power L1, delta T = 2.4 °C
======================================================================
Next, the REMA plug connected to my Blink home EVSE model WE-30CIRE, S/N 101940 running at 16 Amps.
REMA Plug
5.5 °C ambient temperature next to plug & inlet.
17.5 °C AC Power L1, delta T = 12.0 °C
17.4 °C AC Power L2, delta T = 11.9 °C
Leaf Inlet (same Leaf as above)
17.7 °C AC Power L1, delta T = 12.2 °C
15.4 °C AC Power L2, delta T = 9.9 °C
I am getting a Tesla Model S at the end of February. The Tesla will be drawing 32 Amps. versus 16 Amps. Power goes up by the square of the current so all of the above delta temperatures will increase by a factor of four. So, at 32 Amps. the Yazaki will have a temperature rise of 15.6 °C, the ITT plug 10.8 °C and the REMA 48.8 °C. The REMA is clearly defective so I call Blink customer support. I told them my REMA connector is too running too hot and here is their response:
Hi Jim,
Thank you for contacting the Blink Network in regard to the charging hose assembly on your Blink unit. At present, ECOtality is investigating reports of overheating issues with the J1772 plugs, however, these issues only appear to be affecting two vehicles: the Toyoya RAV4 and the Honda Fit. Tesla vehicles have been and are used extensively with the Blink charging stations without issue. The charging nozzles on the Blink units will reach temperatures around 90°F during normal operation due to the power flowing through the connector pins. Does the connector appear to be melting, smoking, or giving off any strange odors? Does the unit appear to have any issues while charging your vehicle? We hold customer experience as the utmost priority and will work to ensure your unit is safe to use with your vehicle. Please advise us of any of these problems so we can better resolve your issue; if you have any questions or concerns, we are available 24/7 via phone or email for your convenience.
Best Regards,
S. Dustin Seyfert

I am sure I do not want to plug my new Tesla Model S J1772 adapter (when I get it) into the REMA plug so that it can “be melting, smoking, or giving off any strange odors” so that Blink (hopefully) will fill fix it. I am not sure why they want me to burn something up and why the above data is not sufficient for them to replace the REMA so the charger is ready with I get my Model S. I will replace it myself or buy another EVSE.
Comments or Advise from anyone?
Jim
