You need to know the current and the time to calculate the lithium-ion battery capacity. The current, usually measured in amperes (A) or milliamperes (mA), is the amount of electric charge that flows through the battery per unit of time. The time, usually measured in hours (h) or fractions of an hour, is the charge or discharge cycle duration.
Figure 9: Wiring of the battery capacity measurement device Prepare a voltage of something around 7V to 9V to the supply input. I have used the Arduino board’s regulator to make the +5V rail. Therefore, never apply a voltage higher than 9V to the supply input, otherwise, you might damage the regulator chip.
The purpose of the capacity, or load bank test is to determine the true capacity of the battery by finding the time that it takes the battery to reach the end of discharge voltage and compare it to the expected time from the battery manufacturer’s published ratings. The ratio between the resulting time and the expected time, with
Lithium-ion battery capacity may be increased by optimizing the battery’s design, chemistry, and production processes. ● Increasing the electrode surface area: Widening the contact area between the active components and the electrolyte may improve performance.
The ratio between the resulting time and the expected time, with a temperature correction, defines the capacity of the battery in percentage. This method is the Time Adjusted capacity test and is the preferred method for tests longer than one hour.
A multimeter can be used to measure the voltage of a battery, which can provide an estimate of its remaining capacity. However, this method is not as accurate as a full charge and discharge cycle. To use a multimeter, set it to measure DC voltage and connect the positive and negative leads to the corresponding terminals of the battery.
