The links only seem to work when clicked from the AEVA site. i have no plans to mess with something that is not broken. if it's possible for me to correct the links here, then i could give it a try, but i would hate to mess up anything over at AEVA. i think it is good to have somewhat of a...

There are lots of pictures in the first post of the OBC troubleshooting thread (it is split into 3 parts due to the large size) that would give you an idea of what you are seeing and will be looking for. All the repairs from that first year have links to their story, what the issue was and how...

Does the car start to READY? If so then use a voltmeter to measure at the 12V battery terminals: if it reads 14VDC then the fuse in the MCU is okay; if it only reads 12V then the fuse is blown and likely the snubber caps on the power board in the OBC are also blown.

There are some fuses inside the EMI filter box, but that is a very very rare failure. i don't think those scorch marks mean anything, but it doesn't hurt to open the EMI box and look inside. If you tried charging and your 12V battery was old, weak or worn out, then you likely had the main...

Maybe too late to recommend to Brush all that dirt off, and then hose it down and let it dry before you remove the cover and open it up. i read thru the OBC thread about 3 times and tried to pull links to the important stuff for an Index to help find the good stuff quickly without needing to...

No. You don't need to remove the OBC to repair it either, see the OBC Troubleshooting and Repair thread for examples and details of numerous repairs.

Lots of videos on the utubes of guys doing surface mount soldering for instrument clusters, speedometers, car electronics, etc. Search for them, find one close to your area, then send a note and ask. they know how to solder and would likely be glad to help make the repair.

Here is a beauty,

Unfortunately the updated forum software threw off all my page referenced links in the OBC Troubleshooting thread, and some pictures are not showing or linked properly. Here is a schematic of inside the waffle plate showing the diodes that can be checked using a DMM with the diode check...

On kiev there is little plastic finger "springs" on the latch side that bumps the cover plate open when the release handle is pulled. There is the black metal piece on the hinge side that seems to be more for rattle-prevention of the hinge rather than helping to open the cover, but i could be...

So both of your ceramic resistors are okay by that measurement of 10.6 Ohms from the white wire over to the solder junction marked "N". The black wire should/will have direct continuity over to the 1st row of solder junctions marked "L", not the blue circled junctions in your photo. No need to...

No problem in swapping OBC--they are not VIN coded. do the white ceramic resistors measure thru for the L and N lines to the waffle plate solder junctions--that is a common failure. Also is the MCU fuse intact (under the little access cover plate)? also the AC input fuses in the EMI filter...

Well, up till now this has been a fairly no-nonsense forum, especially when compared to many others. High signal-to-noise ratio for technical content, etc. The edit button mostly works for making corrections to ensure we are sharing good information. Or a mojulator can make edits/corrections.

That sounds interesting--would you care to go into some details of how this is done? [edit: i followed Mickey's link below and found the description--that's quite amazing]

i wouldn't worry much about the low temperature case with it's long time constant--when it gets cold and freezing outside then it will be just as cold everywhere inside the pack over time. i would be more worried about a quick or fast high heating event such as DCQC or 30 minutes of high...

Did you see page 1, post 11, for how paul did it using crimped ring terminals?

That is a rivet to connect the aluminum current collectors to the positive terminal (cathode). It is also directly in contact with the case. The negative anode terminal is insulated from the case and connects to the copper current collectors, probably thru a rivet underneath the extender tab...

Member piev recently picked one up and let me test drive--and it accelerates so quickly that its hard to believe 6500 lbs. The 4-wheel steering at low speed when parking was an unexpected feeling. A neighbor's father drives a black tesla roadster and it was parked at her house the day...

Measured the LEV 50 cell dimensions and picture of the top plates. The case is steel and can be made much thinner than the aluminum cases that are used on most other prismatic cells.
