NiMh 12V,1.2Ahr Battery Charger
Difficulty Rating: 4/10 Exactly 5 months after my Internship/project at M.A.P.L. Pune, on Lead acid SMF Battery charger, my knowledge on Battery charging was put to test by a Mechanical Engineering friend. I was asked to charge a 12V 1200mAh NiMh battery. Now, before getting into its technical aspects, a little overview about battery chargers. General battery charging techniques- Trickle chargers This charger provides a constant charge rate of ~ 0.1C. The general idea behind keeping the charge rate low is to compensate for the batteries self-discharge. The charge rate being low, the battery can be left unplugged for days!!!The charge rate of the battery should be equal to self-discharge of the battery. Such chargers are generally used in industrial applications , where less of human intervention is required. Float chargers The battery and the load are constantly connected to the source. The float chargers maintains full charge & provides a protection against...
