I pulled the battery pack out of my new I-MiEV over the weekend (cause I already mowed the grass). Put it back in tonight and everything works fine. I just wanted a look inside to see what was there and what was not. I jacked the car up and put four truck jackstands under it so I could get it high enough in the air---in my case 19" from the frame rails to the ground. I used a bubble level to set the pack level with the floor. I used a "Handylift" motorcycle platform lift which has a two foot by seven foot flat top on it (after removing the motorcycle wheel clamp). Before sliding the lift under the car, I removed the two front mount bolts, two power cables, A/C and heater power cables and finally the three control wire connectors. I then put a movers blanket on the top of the lift and postioned it under the pack. I then removed the 12 volt battery ground cable and the high voltage interlock plug. I also pushed the boot around the plug under the floor at the same time. The lift has a 1500 pound capacity and is air operated so I applied air pressure until it was firmly pushing on the bottom of the pack. I removed the two small brackets on the sides of the pack near the rear. I then removed the final eight support bolts and lowered the pack to the ground and rolled it out from under the front of the car. I then took the top cover off the pack. I am glad I watched Ben's videos (thanks) before I did it as there are a couple of sneaky bolts securing the high voltage interlock to the top (along with four spacers that you will find after the cover is off. Inside, as I suspected and if you read my replies in the battery temperature management thread, there is no cooling system for the pack. The pack is entirely sealed except for a small outlet on the top with a little foam filter in it. On the front of the top cover you can see outlines of where the cover would be cut for a cooling duct for both L.H and R.H drive vehicles. If you turn the cover over, you can see the area that the fan would mount to and the rubber plug the closes off where the fan wires would exit. The nutserts for mounting the fan are installed in the cover. There are no battery cooling tubes inside the pack. There are 10 sets of LEV50-8 modules and 2 sets of LEV50-4 modules. The modules are marked 50 ah, and 1440 and 720 watthours depending on size. Each battery has a balancer mounted on the top along with temperature sensors. six sensors on the -8's and four on the -4's. There is a ton of wiring in the compartment but most of it runs to connector blocks that parallel all the wires. There are three contactors in the center of the pack--battery +, battery -, and a charging contactor. There is also a ground fault unit present. The battery management unit is inside the car and I couldn't find any other electronics in the pack. There is a CAN bus loop between modules and the BMU that addresses each cell in the modules. CMU-06 and CMU-12 are the -4 modules. The internal construction is really nice---everything is a buss bar connection, no cables between the modules. You can sure see way these cars cost so much. Wrapping everything up and putting the pack back in was a snap. The blanket was the key to this as it allowed me to slide the pack on the top of the lift for the final lineup. If I could only get a place for my picutres to go, I would be glad to share.

[QUOTE="siai47, post: 12084, member: 1483"] I pulled the battery pack out of my new I-MiEV over the weekend (cause I already mowed the grass). Put it back in tonight and everything works fine. I just wanted a look inside to see what was there and what was not. I jacked the car up and put four truck jackstands under it so I could get it high enough in the air---in my case 19" from the frame rails to the ground. I used a bubble level to set the pack level with the floor.

I then put a movers blanket on the top of the lift and postioned it under the pack. I then removed the 12 volt battery ground cable and the high voltage interlock plug. I also pushed the boot around the plug under the floor at the same time. The lift has a 1500 pound capacity and is air operated so I applied air pressure until it was firmly pushing on the bottom of the pack. I removed the two small brackets on the sides of the pack near the rear. I then removed the final eight support bolts and lowered the pack to the ground and rolled it out from under the front of the car. I then took the top cover off the pack.
