Enginer 2010 PHEV Technical Information

[hobbit]

Very cool on the gen3 experiments; do you have a good feel for
how many amps you're stuffing into the system at any given time?
Any oddities in the car's displayed SOC or "regen cars" that
stack up as you drive?

Just to update...my data logger hasn't arrived yet so I'm limited in what I can see at the moment.

I've made three runs over the past week to measure the equivalent e-miles of a full pack. I shut down the pack as soon as the red LED lights.

The first gave 11emi (but not sure the pack was fully charged), the second gave 13emi, and last night the third gave 18emi (out of 58.7 driven)....so the pack seems to be breaking in and wasting less charge on balancing.

I've got an integrating current-voltage-power meter coming as well, but the current from the DC/DC converter is limited to around 10A.

Otherwise, I've noticed no unusual behavior at all.

The case still needs to be modified or updated to fit under the deck of the GenIII so I'm running w/ it lashed to the deck for the time being.

atfsi,

Thanks. I hope this works out for you. I am wondering what MPG increases we can expect from the Enginer Kit for people who drive the highway 90% of the time, but 18 miles of EV is very good for the price of the kit. Even if you live in California which makes the 4KW kit $4495.00.

Thanks,

Chan

I havn't taken it out for an expressway run yet...that should be interesting !

Remember it's 18 e-miles out of 58.7 miles...I wish I could run it as an EV full time.....

A little more OT here....

This is a shot of the 48VDC to 120VAC converter I picked up on EBay. For using the Enginer pack as an emergency power source during power-outs....

Hey atfsi -- silly thought: you might want to pioneer the concept
of *not* permanently mounting the pack in the boot, but designing
a quick but secure removable setup ... so when you go on long
roadtrips without much opportunity to charge, you can just leave
the thing home. The main advantages of a PHEV are local...

The current GenII case is setup as easily demounted...it's the weight that's the problem......(easily esp since I added a quick disconnect.)

We'll see how the modified case works out.......

The optimum trip for this 4KWH pack looks to be ~ 60miles to get the 20 e-miles.......so far anyway......my daily commute is only 2 miles each way....

I just notice that Enginer.com is taking reservation of the PHEV system. They list the options of having 6 or 8 KiloWatts of battery. Wow that would be nice but heavy?

How is the testing coming a long?

So far, so good...still working on case mods to fit under the deck.

The computer interface came in today....decided on the medusa research MR-PA-60100R-B which is an integrating current sensor w/ USB interface and addl. inputs. ( see Medusa Research )

[atfsi]

Here's an update on the interface...



Showing the modified connections to the shunt.



Here it's installed and working. The shunt is in the negative line from the batteries to the breaker.
