Battery Life Cycle Calculation- Calculating and Battery Life
Generally, battery life is calculated based on the current rating in Milliampere (mA) and the capacity of the battery in Milliampere Hours (mAh). The battery life can be calculated from the input current rating of the battery and the load current of the circuit. Battery life will be high when the load current is low and vice versa. The capacity of the battery can be mathematically derived from the following formula:
Battery Life = Battery Capacity in mAh / Load Current in mA * 0.70
*The factor of 0.7 makes allowances (temperatures, aging etc.) for external factors that can affect battery life.
Runtime = (10 * Ampere Hours) / Load in Watts
But in an LI-ion battery, It is simply the number of times the discharge/charging cycles before come down 85% to its initial capacity.
For 1100 cycles, the lifetime of the battery is about 5 yrs.
How to calculate the battery runtime?
By and large, battery life is determined dependent on the present rating in Milliampere (mA) and the limit of the battery in Milliampere Hours (mAh). The battery life can be calculated from the input current rating of the battery and the heap current of the circuit. Battery life will be high when the heap current is low and vice versa. The capacity of the battery can be numerically gotten from the following equation:
Battery Life = Battery Capacity in mAh/Load Current in mA * 0.70
*The factor of 0.7 offers allowances( temperatures, aging, etc.) for outside elements which can influence battery life.
Runtime = (10 * Ampere Hours)/Load in Watts
But in LI-particle batteries, It is just the number of times the release/charging cycles before reversal 85% to its initial limit.
for example, For 1100 cycles, the lifetime of the battery is around 5 yrs.
To what extent will a battery last
Let's imagine you are building an IoT gadget that spends a large portion of the time in a rest or sleep mode. You'll most likely need to calculate to what extent will a battery last in such a case. You should simply open the advanced mode to discover!
In the advanced mode, you can adjust the accompanying extra parameters:
Awake time is essentially the time that your device isn't sleeping during one operational cycle - for instance, 2 seconds.
Utilization in sleep mode is the normal utilization of your device in rest mode, measured in amperes. This value is most likely much lower than the utilization in awake mode.
Sleep time is the time that your device spends sleeping during one activity or operating cycle.
Basing on the parameters listed above, the battery life calculator machine finds the normal utilization as per the equation
Average Consumption= (consumption1 * time1 + consumption2 * time2)/(time1 + time2)
