Porsche 914 EV Conversion

FEBRUARY 6, 2008

I let out a major sigh of relief today when the new Iota DC-DC converter showed up today along with the synthetic transmission fluid that ElectroAuto said they would send me. I've been biting my nails over the past few weeks, living in fear that my 12V battery would suddenly run out on the freeway in the rain as I drove with my headlights on.

Note the position of the battery pack on the passenger side, which also helps with weight distribution in the car (with one driver). XL1 is visually striking; 153.1

Electro Auto e-mailed me again today to say that the battery racks and boxes have shipped and should arrive on Tuesday! I ran out and purchased several 1-guage pre-constructed battery cables from Napa today to wire the batteries together, but they were very expensive (16 of them at $12.95 Parkrose hardware had it for $7.00/foot

Again, the front luggage compartment with the vertical all-thread in the battery rack for the battery-box tie-down bars. Now that I have more 10 gauge wire, I finished up the wiring on the battery box itself. Here's a front view with the DC-DC converter. The moment of truth for the front battery box.

Before the accessory battery discharge yesterday, I wrote down a list of things to keep in the EV in case there was a breakdown out on the road. I came up with the following items. Any comments for additions or modifications would be welcome. Next up: fixing the stranded car, looking at the PakTrakr and getting the heater fan to work.

The batteries are broken in so I have more current to work with and more importantly 2. With the charger plugin at both work and home, the PakTrakr fuel gauge doesn't seem to drop below the 80% mark, so I think the batteries will last a little while. Two things have definitely made the car more fun to drive. Stay tuned.

Well, after yesterday's letdown with the front battery box not fitting into the steel frame, I loaded up on caffeine and pulled out the grinding wheel. Here is the front battery box not fitting into the front rack. Next up is installing the auxiliary battery. Also, the instructions for the DC kit may not apply to the AC kit.

We chatted about the blown CCPower DC-DC converter and the engine vibrations. Since I fixed the DC-DC converter, we agreed that I would try to find out which conditions would cause it to blow again, if it does. Mike doesn't have an AC kit 914 back at the ranch. I just got off the phone with Mike at Electro Automotive.

In was eager to get the new DC-DC converter installed so I left work a bit early and got to work so I could still drive the car to breakfast with my girlfriend tomorrow morning. The DC-DC converter fits rather nicely in the old space. Here's a closer view of the top of the Iota DLS-45 converter. The new converter is dead silent.

I'm still waiting on the battery racks/boxes from ElectroAuto, so I took care of a bunch of little things that have been neglected so far. Here's the battery tray that the directions said to remove. It's a pity that we have to remove this, but the size of the golf-cart batteries clearly interfere with the latch.

This presents the dilemma of running down the 12V battery while the main pack is charging. If the 12V battery is dead, you need a small 12V battery (9V would probably work) to activate the DC-DC converter relay to bootstrap the 12V charging process. The accuracy of the PakTrakr is only 0.1V

In the process, the DC-DC converter turned on (indicated by red LED) and then slowly decayed to the off state. Since the positive terminal of the auxiliary battery is tied to the unswitched 12V rail, the negative terminal of the battery is at zero volts. Here's the battery box top sitting in place. The moment of truth!

Just before noon, I drove with the ICE vehicle over to the 914, charged the accessory battery with jumper cables for about 20 minutes, then quickly drove the 914 back home to the garage for repairs. Since the DC-DC converter was blown and I didn't want to deal with it, I focussed on some other electrical problems I'd been having.

One of the annoying behaviors of the motor system in my AC 914 kit is that the default DMOC445 parameters causes the acceleration and braking to have oscillations. This is very important due to the weakness of the 914 manual brakes combined with the additional 800 pounds of battery weight.

I lost much sleep last night obsessing about how I could fix the DC-DC converter and, as a result, I was very tired and had an irritable day. I find out this morning from Ross Cunniff (who also recently completed the 914 AC kit), that he has had ABSOLUTELY NO PROBLEMS with his CCPower DC-DC converter.

Inside the front battery box is the middle battery box (goes in the fuel compartment) and a bunch of other parts. First crack! We shall see what awaits.

Note the thick battery cable going through the lower grommet on the left to connect the front batteries to the rear of the vehicle. The holes for the accessory battery mount fit just fine.
