My DIY 10 hour external laptop battery pack

post #1 of 16
Thread Starter 
My Toshiba S75D is an awesome machine, but the rather lacking battery life needs to be addressed, and this is an area where I excel smile.gif

Specification:
Battery pack – 14.4v, 10.8ah (24 Li-Ion cells, 16.8v nominal voltage)
Low Battery Alarm – Blue LED = full, flashing blue = good, red = low, flashing red and beep = dead
USB Charge port – 5v, 3a
Output – 19v @ 6a (Max); Laptop draws 19v @ 4a fully loaded and charging
Charger – Astro Flight Lithium (connected directly to battery pack) -OR- solar


The testing phase! According to my calculations, this power pack will run my laptop for ~10 hours under light load (not charging internal battery), or ~4 hours under 100% full CPU load (not charging). Then I have the ~3 hours in the internal battery. ~13 hours without access to an outlet is unbeatable!!


I decided that I wanted a USB charge port as well for phones and the like.

I figured out that an 80CD wallet is the perfect size for all the components. I ordered a hard plastic one on eBay for $5 and will modify it for this project. Having a zippered enclosure makes it easy to open and charge with my Lithium charger. Knowing this, I did the wiring and a mockup installation in another 80CD case I had laying around. The final version will be much more refined, of course.


Here you can see how everything fits in there rather well.


Finished up the wiring, lots of heat shrink for professionalism and safety. I even heat-shrunk the USB charger board.


Wiring looking good…


Everything fits!!

I'll update the thread after I get the new hard plastic CD case I ordered and finalize the device.

(Do not try this at home if you're not experienced in electricity and electronics, as fire is a real possibility if lithium batteries are improperly used. I have 20+ years experience and college education in the field)

I lied about the next update being when I get the case. I've decided that I want the pack to be able to charge itself and ordered a pair of these panels for less than $13:



That's 4w of self-charging potential right there biggrin.gif They'll fit perfectly on the CD case that I'm enclosing this build in:

Got the hard plastic CD case and transferred the components from the temporary one. The red color is good for when it'll be sitting in the sun charging, as less heat is good for batteries. It's getting a topping up charge in this pic. More pics will follow once I get the solar panels and finalize the design.

Ripped 'em out of laptop batteries for defunct machines. Specifically, a few Dells. I have two more packs of identical cells as potential replacements.

EDIT: As a matter of fact, I only have about $30 in this project including the case, solar panels, and DC-DC convertors. The rest came right out of my electronics junk boxes.

I gave the battery its first real world test yesterday in class and it performed very well for over 4 hours of medium CPU load - the PLC simulation software pegs one processor core at 100% which draws some power - not battery friendly programming there. I had the brightness up too.

It took 5.58ah from the charger for a full recharge after that, indicating I discharged it roughly half way. This is in line with expectations considering I calculated roughly 4 hours at full load and 10 at idle.

Can't wait to get the solar panels in hand!!

Dont most laptops throttle on battery? Unless the PC doesnt realize the difference and thus operates at optimal levels?

As far as the PC is concerned, it's running on AC power when on this battery, so it doesn't know the difference.

I don't think my particular laptop operates much different in AC or battery mode, it just goes by the performance settings, which I have enabled the same way for both AC and battery.

The solar panels finally arrived and I got to quick work installing them in my external battery pack.


First I wired them in series and soldered on wires to the tabs.


Then I scanned the actual panels and printed a life size template.


I taped the template to the case and using a utility knife and metal straight-edge, I cut out the hole as best as I could.


I don't think I did too bad, really. Cutting plastic isn't a particular specialty of mine rolleyes.gif


Panels temporarily installed to get an idea of final result.

Next step is to install a diode and wire the panels to the battery bank. Next update should be of a completed project!
