And my son turns 11.   Coincidence?  Yep.

I forgot to note that the RAVolt has now logged over 4,000 electric miles or 160 gallons of gas.

With the nice weather, I’ve been driving electric nearly everyday and racking up the miles.  Today the RAVolt’s Odo spun to 150500.  The amount of gas I have not bought is adding up - hahahaha!

Even with the stock market meltdown, Laura’s impatient to get our Honda Fit….tick, tick, tick.

BTW: We’re planning to be at the 2008 Austin Maker Faire October 18-19.  The RAVolt will be in the AustinEV area while my boys have a table hacking Wii Motes - bring your mote and they’ll make the “A” button glow.  Alex is buying all the supplies out of his own $$$ with the dream of making a profit at the Faire (DIY kits for @ $10-12).  Can’t argue with that!

I put myself into a stressful situation yesterday.   I promised to pick up my daugter from a birthday party near the Trail of the Madrones deep in the heart of Westlake (clap clap).  If you are not fortunately enough to drive in Michael Dell’s back yard, you may not realize that Westlake is 1) hilly, 2) confusing, 3) not accurately Google mapped.  In an ICE car that’s no big deal, but an EV is very stressful when you’re lost, past bingo (1/2 fuel), late, and swelting without A/C.I ultimately found the party (10.5 miles into my 20 mile range) and drove conservatively (belated appologies to south bound 360 traffic) to my daughter’s soccer game.  It’s important to note that 20 miles is my safe range and it’s possible to nurse more miles out the batteries.  Yesterday I got 22 miles and could have gone longer.  Yeah!I drove 30 miles today.Yes, 30.  The batteries got a long drink after the deep discharge yesterday then I took a 6 mile trip with recharge bounce at home.  The result was extra long range!  Even after 30 miles (ok, 24) the batteries had relatively little sag.  I probably could have gone another 5 miles!Hopefully this means that nursing my batteries has been paying off and they are recovering some of their lost zest.

Alex and I watered the RAVolt’s batteries yesterday.  I’m right on schedule, but the cells were very dry (4+ oz instead of 3) due to Austin’s relentless heat.

I can tell when the cells are getting dessicated because it cuts down my range (to about 18 miles).  That leads to sphincter tightening when my batteries start to sag uncomfortably and I’m a few miles from home.

Post-watering, I did a 20 mile ride and the batteries were still nice and bouncy.

Sure it’s hot - that’s what fans are for.

Today I got to watch (and photograph - belated sorry to other drivers on Bee Caves) the RAVolt turning over four zeros!  That’s a huge milestone for the glider and over 3,400 electric miles.

An, yes, the old gas gauge is covered with a sticker that says “Outta Gas! Running on E-”  I simply can’t resist EV geek jokes (non-geek translation E- = electrons).

Almost…   Spinning…

There it is!

I’m within 80 miles of the 150k mark!

Wow…quick response from the AustinEV team!  Thanks.

From Brian:

It’s Cupric Sulfate.  It’s formed by the reaction of Sulfuric Acid (in the air, bubbling off from the battery) with the exposed copper of the battery wire lugs. On the plus side… It’s no longer reactive after forming Cupric Sulfate, so it will not hurt anything.  And another positive, is that it’s the copper lugs that are corroding… and they can be replaced
much easier than the lead battery terminals.  

I do not think it’s a big problem.  If you were really concerned, you could re-tin the copper lugs, or put some waterproof paint over the lugs and terminals.  Waterproof paint would make it much more annoying
to change / remove your wiring at a later date though.   :-/

From Mike:

Try coating the exposed surfaces with vaseline.  It will keep the air and
moisture off and greatly reduce corrosion.  There are several brands of
spray on corrosion preventative, but from past experience vaseline works
just as well, cleanup is pretty easy, and it is cheap.

From Roy:

I get that a lot too, it does not effect conductivity for me.
I usually brusk off the powder with a stiff nylon brush and vacume it up.

I was watering the RAVolt’s batteries this weekend (as usual, 1 basterfull per cell) when I noticed that one of the battery terminals is corroded.  The powered is bluish and there is no acid splash around the terminal.  I’m not sure what to do yet, just reporting the problem.  I’ll ask AustinEV for help.

Corroded:

Clean:
