Battery Equalizer Schematics Rev 1.0

Porsche 914 EV Conversion

I'll have to modify the circuit with a voltage doubler in the final stage to work with 8-volt golf-cart batteries for the 914 EV kit. By clicking on the images, you can get a much larger version of the pictures. Any feedback on how to improve the circuit would be welcome.

More Delays

Porsche 914 EV Conversion

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.

Measuring State-of-Charge on Lead Acid Batteries

Porsche 914 EV Conversion

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. Both US-Battery and Trojan have 8-volt golf-cart batteries. With the AC system, I'll probably be pulling less amps and am looking forward to the extended range.

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. I received the suspension parts from ElectroAuto today.

These high-capacity 8-volt golf-cart batteries are 70 pounds apiece. I got this battery strap at a Yamaha golf cart dealer. A modification of the prior strap is basically what is suggested in the DC kit instructions. Tonight was an evening of heavy lifting. Here are the batteries in the front box.

Closing up more loose ends.

Porsche 914 EV Conversion

One of the other 914 kit converters questioned why the accessory battery couldn't stay in the original tray, but I decided to remove it anyway and have the accessory battery up in the front trunk near the DC/DC converter. It's a pity that we have to remove this, but the size of the golf-cart batteries clearly interfere with the latch.

A very low cost EV is taking a golf cart transaxle or whole GC rear/seat and weld, ect a MC front end, frame, title to it, change the batteries from 6vdc to 12vdc to double the voltage and use larger dia VW Rabbit tires and you can have a nice 1- 3 person MC trike that goes 45-55mph and 50+ mile range. nk Related Posts From Green Inc.
