AI Customer ServiceThe battery energy calculator allows you to calculate the battery energy of a single cell or a battery pack. You need to enter the battery cell capacity, voltage, number of cells and choose the desired unit of measurement. The default unit of measurement for energy is Joule.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
Estimate the remaining capacity: Multiply the SOC by the battery’s rated capacity to estimate the remaining capacity. Let’s assume we have a 12 V, 100 Ah lead-acid battery, and we want to estimate its remaining capacity using the OCV method.
To calculate the capacity of a lithium battery, you need to know its voltage and amp-hour rating. The formula for determining the energy capacity of a lithium battery is: For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be:
The unit of measurement for battery energy can be: joule [J] or Watt-hour [Wh] or kilowatt-hour [kWh]. Calculate the energy content of a Ni-MH battery cell, which has the cell voltage of 1.2 V and current capacity of 2200 mAh. Step 1. Convert the battery cell current capacity from [mAh] to [Ah] by dividing the [mAh] to 1000: Step 2.
To estimate battery capacity using a multimeter, follow these steps: Measure the OCV using the multimeter’s voltage setting. Compare the measured voltage with the manufacturer’s voltage vs. state of charge (SOC) chart. Estimate the battery capacity by multiplying the rated capacity by the SOC percentage obtained from the chart.
