Those of visit this site regularly will know that one of my personal projects has been to convert a 2004 Prius (affectionately known as Velma) to a plug in hybrid.
The conversion process has certainly not been plain sailing – but that’s been due to my own stupidity and impatience. (Simply put, I didn’t properly check the battery health when I installed a second-hand pack. I learned the hard way and blew one pack up, a few days after installation. £300 later and I was able to re-install a PHEV pack.)
