Battery Analyzer for RC Power

摘要

Klowing the discharge characteristics of the battery in your portable drill may not be very important, but having this kind of information is vital if you want to be competitive in any type of electric RC event. I was rudely reminded of the need for such a device when my electric boat stopped in the middle of the lake! It was only two minutes into its run that should have lasted six minutes when it gave-up. I suspected the battery was bad, but this should not be the way to find out! If I was able to monitor the batteries performance during its usable life span, a problem may have been detected. If you know what your battery is capable of, it is easier to develop a winning strategy. This battery analyzer project is designed to test the "health" of battery packs used in radio-controlled vehicles to drive their motors. An effective way to test the health of a battery pack is to place a normal operating load on a fully charged pack, and then record the voltage levels while it is discharging through a test load. The information produced from the recorded data will create a graphical "discharge curve" that can be used to examine its performance level and determine the health of the battery under test.
