Battery Golf Cart Kits 
Porsche 914 EV Conversion
FEBRUARY 18, 2007
I'm currently working on a battery equalizer for the 914 EV based on the whitepaper at the following link: [link] The above two schematics show the circuit that I'm experimenting with using 12V batteries. It seems to work fine on my bench. By clicking on the images, you can get a much larger version of the pictures.

Since I'm still waiting on parts from ElectroAuto, I decided to take the plunge and do some extensive research on Lead-Acid battery technology. The 914 AC kit uses 8V golf cart batteries and I'm wondering if different batteries like Hawkers or Optima Yellow-Top batteries would be better.

Over the past few weeks I've been trying to contact the folks at Electro Automotive to get the status of the EV 914 kit. They finally responded last night and apparently they're completely buried under the demand for EV conversion kits. He got one of the earlier DC motor kits for the 914 from Electro Automotive.

These high-capacity 8-volt golf-cart batteries are 70 pounds apiece. Here are the batteries in the front box. I pre-laid out these batteries on the floor to guestimate what the connections between the terminals were. Here is the battery strap designed for these kind of batteries. And the rear box.

If you hadn't read before, the 18 8-volt golf cart batteries add 800 pounds to the weight of the car, so the suspension needs upgrading. The real gamble is how fast the rest of the kit shows up. On a slightly downer note, I ordered a $250 special desulfator for 6-24V batteries.

After some significant debate at the Civic-EV Google Group on whether to use a clutched or clutch-less system, I'm going to pursue using a clutched system for the initial revision of this kit. Here is a picture of my transmission label: Next up: thinking about batteries and the controller system.

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.
