Second-tank update on the DIY Plug-in Prius

One of the personal projects that keeps me busy is my own plug in car – my 2004 Toyota Prius. I converted the car from a regular Prius to a plug in Prius earlier this year. After a few initial hiccups with a bad battery causing one of the additional battery packs to die prematurely I’ve had a few months worth of plug in hybrid driving. But at the end of the day I have a driveable PHEV Prius, which I have the satisfaction of knowing I converted.

Today I filled up my car after finishing the second full tank of gas since converting the car to a plug in. The last time I filled up was on April 3rd. Today is May 8th. Admittedly, I was away for seven days during this period, but keeping up with this I’ll be only filling up once a month.

Its not a full EV, but I fell better with fuel economy like this...
