Measuring State-of-Charge on Lead Acid Batteries

Porsche 914 EV Conversion

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. Given that I'm using lead-acid technology, one of the big challenges is knowing just how much charge is left in the batteries so I don't run them down below 20% SOC (or state-of-charge).

Hanging out with NEDRA

Porsche 914 EV Conversion

Summer events have held me back from working on the 914EV, so I headed out to Portland International Raceway to get a boost of inspiration from NEDRA (National Electric Drag Racing Association) to continue the project. This time, White Zombie is running with A123 Lithium-Ion Batteries instead of lead-acid. Here are some photos.

New Vacuum Pump and Fixed Wiper System

Open Source Civic EV Kit

I'm all ready for the long rainy winter here in Portland. I think the next major project (If I don't go out and purchase a Nissan "Leaf" outright) is to upgrade the batteries to lithium-ion types when the AGM lead-acid batteries die. After shelling out a whopping $6.50 Hopefully that will be two years out.

What I do need is an affordable alternative to Lead Acid. About 15 amps from a 110v outlet is adequate. Like most people, I tend to drive less than 30 miles a day, so I won’t run out of charge.
