Bad Timing

I got the voicemail that my batteries are ready to be picked up, starting Monday! I am traveling on business this week, so it will have to wait until Friday. Doh! So Battery Day is now 3/5. Can't wait!

DC/DC Converter arrived

The refactored DC/DC converter arrived from Belktronix today. This DC/DC can take inputs of between 150V - 200V input, right around the projected traction pack voltage of 166V. Installation this weekend!

Battery day is 2/23 or 2/24

Called EV components today, and they reported the lithium cell shipment shows up 2/22, which means after their sorting I can pick them up in Lacey either 2/23 or 2/24. Awesome.

Lexan battery box lids installed

The lexan clear battery box lids, machined to my specs, arrived this afternoon. Isn't it a bit ironic that some of the cooler things in my EV are those things that you really can't see? They will ooze coolness by what they allow the viewer to see - the lithium cell monitoring LEDs (each cell monitor will have a red and green LED, which are lit or not depending on cell state).

Here is a picture of the front battery box...
What - can't see it? Here is another...

Either the lamp is levitating, or there is a lexan lid - you be the judge!
Here is a picture of the rear battery box with the lid on...
A little easier to see this one with the reflection!

DC/DC converter is almost done. Almost time to buy a real car battery for the aux electronics. That's another thing - the last design only allowed room for a small motorcycle battery for the electronics, which stressed under load. This design actually has one of the former traction pack spots in the front reserved for a proper group 34 car battery - so no potential for 'brown outs' in the LV circuit going forward.

Getting antsy - where are my lithiums?!
