Enginer PHEV Technical Information

[lex28]

Hello, I am new to the board and am installing a 2kwh system in my 06. I can not get the enginer system to turn on. The LED's will not light up. I checked t the connections at the computer, everything is fine. Any help would be greatly apprecieated. By the way I have a small round fuse that came in the kit. Anyone know where it goes.

Did you turn on the circuit breaker near the charger? The fuse should be an extra one.

Yes the circuit breaker is on.

Are these the LEDs on the converter or the ones at the switch ?

After speaking with Jack it appears that the converter might be bad. He helped me trouble shoot the PHEV plug and narrowed it down to the converter. The lights on the switch will not light up, but the converter will have the green light on. I have 50 .5 volts coming into the converter and nothing coming out.?

On mine, the green LED up front at the switch rarely lights, if at all, but if the green LED on the converter is lit the converter is working...

The red LED at the switch does light when the unit shuts off but it isn't as bright as it could be either....

The switch assembly needs to be replaced w/ brighter LEDs...

That means you have a defective switch panel PCB(most likely). It's supposed to light. It's not the brightest in the world, but when installed properly, it's visible during the day.

This is good info to know. Thank you to all. One more question, after connecting my battery bank, all I can get on a charge is 50.6 volts. I am going to use four Hawker SBS 38ah batteries. Could this be the problem on why the converter will not put out power. It might be to low on juice. I read that the batteries I will be using will charge to 1.8 volts per cell? Anyone know what this means? When I spoke to Jack he seamed to think that the converter might be bad. Back to the batteries don't know why I can't get more charge into them? Any ideas? Thank you once again.

Could be, but I'm doubtful. Is this 50.6 while on charge, standing idle, or on load?

I'm not completely convinced that small lead acid batteries will work here. 38 Ah lead would be rather marginal, I think.

I read that the batteries I will be using will charge to 1.8 volts per cell? Anyone know what this means?

That makes no sense. However, discharging to 1.8 VPC (per 2V cell, i.e. a sixth of a "12 V" battery) isn't uncommon. That would be a total of 43.2 V at the end of a cycle, which would be like 2.7 VPC for Lithium. That could work.

Back to the batteries don't know why I can't get more charge into them?

50.6 V is 12.65 per "12 V" battery, which is about all you'll get from lead acid once the charger is switched off. (With the charger on, you'll get between 13.6 and 14.7 V or even more, depending on the charger). That should be enough to get the converter working, unless the batteries sag to under about 11 V under the ~80 A load.

Well I came home early today and diconnected my batteries. I charged each one of them indivisually and they took a 13.5 volt charge. I am hoping that my charger is not bad, as it will only charge up to 50.6.
