Re: i-MiEV not charging, high voltage warning light and battery

It sounds like there may be some aftermarket hacking required in the near future. But at that point you'll probably end up spending far more than you should have...

Re: Prelude conversion project - some questions

I use Sketchup a lot for drawing all sorts of stuff, and I was amazed to discover that some kind individual decided to draw an entire model of a 1988 Honda Prelude! Prelude battery size up.jpg Prelude battery placement.jpg Perfect for sizing up the battery! It should fit neatly where the fuel tank w...

I think @weber might have some clues? I suspect harvesting them from old panels would be too slow and painful.

Re: Arduino cell cycle tester project

Reviving an old thread here! I've changed the setup so I can test a single cell instead of two in series. I figure why spend more money on power if you don't need to? Jonathan Bilssett from the University of Nottingham asked me to test one of his 10 Ah lithium cobalt pouch cells for cycle life. The ...

Yes, correctly spotted ☺. Pin 5 wouldn't grip the solid core wire properly so I used 2 instead.

Re: Inside a Model 3 battery

Looks like the cells are cooled radially - consistent with earlier reports of battery cells being glued to cooling strips like bandoleers.

Re: Prelude conversion project - some questions

It was for the battery cooling, but if I can plumb into the car's AC it should be more effective and take up far less space. I've devised a bit of a flow-chart for how the battery thermal management system will work. Battery thermal management program.png In essence, if the temperature is below 22 d...

Re: Inside a Model 3 battery

The negative busbar (you can see the black pen) has the fusible links connected to the side of the cell can (negative terminal) while the positive terminals are fused to the next busbar along in a s...

Re: Powering the home from spare EV charge?

If you plan on building an EV, you can plan your home storage battery as well. Yes, the two batteries can (and probably should) differ - EV batteries are generally rated to high power discharge, while home storage cells are less powerful (and therefore cheaper). If the battery of the vehicle is betw...

Re: The Energy Retailers Strike Back. Will Cheap Off Peak Rates Kill Battery Storage?

I think the EV plan is more about setting a system up and tweaking it later. Right now, a general off-peak rate is better value than the EV rate, but the $200 incentive makes it worth considering. I would think that midday will soon become the cheapest (and most stable) time to charge an EV. Workpla...
