## Description

When engineering an electrical device, you will need a source. Most of the time, the source for the device is the wall outlet, other times it’s a natural source such as the sun, and sometimes a rechargeable battery is used. There are many factors to considered when choosing the correct rechargeable battery for a device. One of those factors is the power of the battery, another is the temperature of the battery, and another is the battery life estimation or how many times the rechargeable battery can be discharged and charged again. In order to find the life of the battery, you must find the state of charge and the depth of discharge. The terms state of charge and depth of discharge refers to the amount of charge left to be distributed in the battery. State of charge is the amount of charge left in the battery and depth of discharge, the complement of state of charge, is the how far a battery is close to being fully discharged. The charge of the battery can be found by measuring the voltage, the energy potential of two points per charge. For this research, voltage sensors are attached to the battery, the battery is discharged and then charged again, and the voltage is measured after the battery is recharged. The voltage after the recharge is compared to the original charge of the battery and a rate can be determined. Once the voltage is fully drained, the life estimation of the battery can be determined. It is important to know how many times a rechargeable battery can be recharged. Electric cars, cellphones, and many other devices use rechargeable batteries, so knowing a battery’s life so it can be determined how long the device can be used.
