Enginer PHEV Technical Information

Measuring Charger Efficiency:

Input is 935W



Output is 15.15A * 53.5V = 810.5W


Efficiency is 86.7%.

I used a 25 ft, 12 Gauge heavy duty extension cord in this case. Previously I used a 100 ft, 14 Gauge extension cord and the input was 1058W. In that case, the efficiency was 76.6%. The extra 120W was caused by the higher resistance of the longer cord.

First post has been updated with charger efficiency info.

o.

A quick correction to your post
Output is 15.15A * 53.5V = 810.5W

....

I'm sure you mean 810.5W

Thanks for the update. Do you think there will be a noticeable difference between using 50ft 12G and a 25ft 12G cord? Would you recommend going to a 10G or a 15ft cord?

Updated to 810.5W.

I think a shorter cord and/or larger gauge wire will help somewhat, but I have no idea by how much.

Is there any info yet on the DC/DC converter?

As soon as I finish the install, the first thing I will do is to establish the converter efficiency, at both max current and lower current. Hopefully this weekend I will post that info.

Could you take a picture of any key markings on the the Converter and charger. Model number, and the like. I can't find any docs on either, although the charger should be on thunder-sky or mottcell, but google might find it quicker than me.

There are no markings on either other than what is listed on the first post.

OK... I looked at the picture and I thought I saw "Model" but it was really "Made in..."

Thanks for all the good pics.

Added info to the first post about the DC/DC converter.

Voltage output is programmed at factory or by field support personnel through the RJ-45 port. Future enhancement is a user interface that will monitor useage and SOC.
