Now that you have the necessary information and adjusted discharge current, you can calculate the battery capacity by using the following formula: Battery Capacity = Actual Discharge Current (I_actual) × Discharge Time (t) For the previous example, assuming a discharge time of 10 hours, the battery capacity would be:
The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
Energy is calculated by multiplying the discharge power (in Watts) by the discharge time (in hours). Like capacity, energy decreases with increasing C-rate. Cycle Life (number for a specific DOD) – The number of discharge-charge cycles the battery can experience before it fails to meet specific performance criteria.
Default is 100%. Click the “Calculate” button to see the estimated runtime in hours. The calculator converts battery capacity from mAh to watt-hours (Wh). The formula used is: batteryWh = (batteryCapacity * voltage) / 1000 Then it divides this energy by the power consumption of the device to estimate the running time:
The Battery Run Time Calculator is a pretty productive tool. It is used for estimating how long a battery will last based on its capacity and the power consumption of connected devices. By inputting the battery’s voltage, ampere-hour (Ah) rating, and the device’s power draw in watts, this calculator can determine the approximate runtime.
For example, let’s say you have a 100-watt-hour lead-acid Battery that provides 90 watt hours over 10 hours at room temperature (20°C). To calculate its efficiency, divide 90 by 100 and multiply by 100% – giving you an answer of 90%. What is the Typical Battery Discharge Rate? A battery’s discharge rate is the rate at which it loses charge.
How to calculate output current, power and energy of a battery according to C-rate? The simplest formula is : I = Cr * Er or Cr = I / Er Where Er = rated energy stored in Ah (rated capacity of the …
