Right now my interest is in module refurbishment:
This chart shows the effect of replacing the lost water from two NHW11 battery modules and successive discharge-charge cycles. As you can see, I'm taking used battery modules at 2.2 Ahr and with water replacement and reconditioning discharge-charge cycles bringing their capacity up to a little over 6.5 Ahr. Here are few more photos showing some of what I'm doing:
My thinking is if we can refurbish our worn out battery modules for $5 in parts and water, for ~$200 plus labor, we'll be able to significantly extend the life of our hybrids. It looks like about $100-300 in special tools and a well written instruction manual, any reasonably skilled, 'do it yourself' mechanic can refurbish their own 2001-03 Prius battery. Best of all, this approach puts a permanent service plug in each battery module so annual or bi-annual water replacement will keep these batteries running until the wheels fall off.
BTW, the battery recharger, if done right, can also work as a plug-in lite. What this means is in the evening, the 2001-03 battery can be safely tickle-charged to 80% SOC and at the same time, the health and status of the individual modules checked. This will give the owner-operator a 'boost' during the next day's warm-up and an early indication of marginal modules.
So what'ca think? Right priorities?
Did I mention I have one NHW20 battery module and it looks like a well designed system will also work for the 2004-current Prius.
