Build a Computer Controlled Battery Manager

Posted on Feb 6, 2014

BattMan II is a computer controlled battery manager, intended for typical rechargeable batteries used by R/C and electronics hobbyists, as well as various consumer product batteries. BattMan II has the following capabilities: Works with Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), Lithium-Ion (Li-Ion), Lithium-Polymer (LiPo), Lithium-Nano-P

hosphate (LiNP), and Lead-Acid (Pb-Acid) batteries of 1. 2 to 14. 7 Volts.      Requires sufficient memory to comfortably run Windows, a few megabytes of free hard disk space, and 800G—600 or higher resolution display. If you want to modify the software, you`ll also need Borland C+ Builder 5 or newer. BattMan II is a fairly complex project, and this article assumes that you have some electronic project building experience. If you`re reasonably careful in construction and follow the testing and calibration instructions closely, you should have no problems getting it to work. Your success with this project will benefit from an understanding of how it works, so please read the next section carefully before you plug in the soldering iron. If you don`t want to build this project but need a device like this for your consumer electronics batteries, you might consider the La Crosse Technology BC-1000 AlphaPower Battery Charger or Maha Powerex MH-C9000 WizardOne Charger-Analyzer. This performs many of the same functions as BattMan II, but only for AA and AAA NiCd or NiMH cells (up to four at a time). The La Crosse charger also comes with adapters to let you use AAs in devices requiring C or D sized cells. The power supply I used is a commercial off-the-shelf model that can supply 18 Volts at 2. 2 Amps. I purchased mine at a surplus store. Any similar power supply will do, so long as it produces 18 to 20 Volts, and enough current for...
