This free online battery energy and run time calculator calculates the theoretical capacity, charge, stored energy and runtime of a single battery or several batteries connected in series or parallel.
The 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.
How to size your storage battery pack : calculation of Capacity, C-rating (or C-rate), ampere, and runtime for battery bank or storage system (lithium, Alkaline, LiPo, Li-ION, Nimh or Lead batteries.
The battery cell energy E bc [Wh] is calculated as: \[E_{bc} = C_{bc} \cdot U_{bc} \tag{3}\] where: C bc [Ah] – battery cell capacity U bc [V] – battery cell voltage. The battery cell energy density is calculated as: volumetric energy density, u V [Wh/m 3] \[u_{V} = \frac{E_{bc}}{V_{cc(pc)}} \tag{4}\] gravimetric energy density, u G [Wh/kg]
Frequency to Energy Calculator: Enter the values of Planck’s Constant h (6.626*10-34 J/s) & Frequency v (Hz) to determine the value of Frequency to Energy E (J).
Here's a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge current of your battery packs, whether series- or parallel-connected.
1 Φεβ 2019 · The following formula applies to series circuits: (V total = V 1 +V 2 etc.). This will provide you with extra voltage for the load, but no extra current (I total = I 1 = I 2 etc.). The series example shown in Figure 1 works out to be 36 V with a 1 A current capacity.
