New Voltage for an Old Zivan

Posted in Charger, Tuning at 7:51 pm by Administrator

I spoke with Mark at Elcon yesterday and he said my charger is ready and has been reconfigured to 148V. They couldn’t do anything about the amperage. NEWS Watch For The New Porsche Blog!!!

Balance your Car, Balance your diet, Balance your life

I had one heck of a time loosening the gland nut from the flywheel. I tried to do it using the combination a breaker bar and various methods of immobilizing a flywheel without the starter ring. Before coming up with a workable solution I broke one bolt, bent another, snapped a 914 motor mount bar, split an SK breaker bar at the swivel, and bowed a Thorsen breaker bar.
I finally cut and welded a tool that I could use to immobilize the flywheel using the clutch bolts to hold a steel plate in place. I did have to buy a very sturdy breaker bar made by a company called Proto Tools from an outfit called RAYCO. Using this new tool and a steel tube I attempted to loosen the 36mm nut again, this time with success. While applying torque pressure to the nut with the Proto bar and steel tube extender, I persuaded the thing to come loose by gently beating the life out of it with a hammer! The Proto breaker bar cost 50 dollars but when I felt that gland nut come loose, it was worth every penny. Once that task was done I took the fly wheel up to Valley Balancing and dropped it off. The whole process took two days. The next morning Steve at Valley Balancing called me and said my flywheel was ready. Ken who did the actual work has also done some work for NASCAR. I was right in thinking that the vibration was in my flywheel as he did a lot of work to get it balanced. By that I mean a lot of drilling. It was way off. I couldn’t wait to get it in the car. I was on my way home with it when I got a phone call from Cars Etc, that my 914 was ready to be picked up. They are somewhat overflowing with work and didn’t want to put the newly painted and buffed car out in the weather so I needed to make arrangements to trailer it to my house. I called Little Dave and he said he could help but his van needed new brakes and shoes. He already had the brake pads for the front and the shoes for the back so it was a simple matter of helping him put those on the van. Which we did but not before having to make a trip to the auto parts place to exchange some brake shoes which were the wrong year. Which incidentally Little Dave had purchased the year before and did not have the receipt for. O’Rielly’s auto parts not only were willing to do the exchange but Dave got $11.00 back on the deal. We finished his brakes and got my newly painted 1973 Porsche 914 roller from the shop. It was late and rain was expected that night so we dropped it off at Dave’s place under the carport. This gave me time to bring my 95 Jag back to life and move it out of the garage so that the Porsche has a place to keep out of the elements. Which is where it resides now… in my garage, out of the elements.

The 50 CAL Bottom Balancing Machine

Posted in Batteries, High Voltage System, Lets All Plug In, Tuning at 12:17 pm by Administrator

After frying my Revolectrix Cellpro PL6 twice, trying to bottom balance my 42 cell 180Ah pack (one battery at a time on the second go round) I have come to the conclusion that there is a need for a heavy duty bottom balancer. The first time I Fried it Revoelectrix sent me an RA (return authorization) and I paid the shipping to send it back for repair, they paid the shipping to return it to me. the second time Revoelectix quit answering my emails and won’t return my calls. So I am stuck with another piece of $250.00 junk which I have to replace some MOSFET’s on someday. That being the case and me not being one to give up easily, I seem to be in the unique place of having to come up with a tool which will bottom balance higher Ah LiFePo4 cells, and since no tool seems to be available, I am also in the precarious place of having to build one, which I have done and am testing it as I write this. So far it works quite well discharging one 180Ah cell (CALB SE) at a time. I am starting at 3.28Volts and it takes about 4 hours per cell. If the batteries were discharged down to 3 Volts ea it would only take about 45min per cell. I plan to make this bullet proof and send it to the master of product testing, Jack Rickard at EVTV (if he’ll have it) to see if he can fry it. If it passes the test and gets the EVTV stamp of approval, I will build and sell these. But not until the prototypes have been thoroughly tested. Who knows, I may even get these confounded batteries fully bottom balanced. I know I have been living on the razors edge and taking a real chance with my pack by not having the whole thing bottom balanced. I bottom balanced some and top balanced the rest to make the charges equal right before Laguna Seca. This is the wrong way to go about it. Fortunately these batteries are amazingly resilient and I have not observed that any damage was done. But now that I have a proper heavy duty bottom balancer I am confident that this pack will be balanced well.

I received my GPS Speedometer from Speedhut. It sure is pretty. I am almost ready to embark on the long ride uphill from Delhi CA to Sonora CA. I only need to finish bottom balancing twenty more cells and then I can charge to a much higher capacity then I have been. In the meantime I am finishing the design of the interior and the process of sealing EVIE up for those colder wetter days. I also received my contactor for my heater which I designed last year. Lots to do and little time to do it. I just keep on pluggin away at it little by little. I am embarking on a new green business soon… watch this blog for further details… I can only say this… It involves Green devices, EV’s, Fairness, Public awareness, and Earthly preparedness. Thats all for now. I will let you know how the Central Valley to Foothills run goes.

Mazda Laguna Seca Raceway, Monterey CA 07-01-2012

EV1E’s Debut as an LiFePo4 powered vehicle proved to be a success. We placed third in the “electric vehicle conversion” division (now ask me how many vehicles were in our division.) Not bad considering I have never driven on a race track. The event was wonderful and enlightening. There were more production cars then conversions. Representatives from Tesla, BMW, Coda, Nissan, as well as the Kleen Speed race team were present. This says something very positive about the future of electric vehicles and hopefully the future of our environment as well.

Happy New Year 2010

Posted in Tuning at 11:08 am by Administrator

Here is the update. On Dec 20 EV1E was registered (Thanks again Sharon and Crystal), on Dec 31st I received the title in the mail. Although she runs, I am still working on her. I have been making little trips to the store and into town with her. Cosmetically she needs work and I need to do a little more tweeking on the mechanical side and some on the program which makes her run. Improvements in performance etc. All in all though, she is a really good car.

New Tires and a Precision Alignment

Posted in Drive Train, Road Test, Tuning at 6:11 pm by Administrator

I got EV1E back from Bob yesterday and what a difference. Jason down at Big J Tires, helped me pick out a low resistance tire and then his team did a first class job on the front end alignment. They checked the rear end alignment and Bob Tumazi took it from there. He made the adjustment and now EV1E scoots down the road like she was meant to. I am having a special transmission re-geared for her shifting points as they are different then an ICE vehicle, that should help a little more. For the record I was keeping up with traffic on 99 when I brought her home yesterday. When I got home I had used 1% of the charge. Wow! This really works… you should get one. Next week The Body Shop.
