Do you have a 12v device you need to power but don''t know what 12-volt battery you need? For those running a continuous 12-volt load, an adequately sized deep-cycle battery is a must.. This calculator is designed to provide an appropriately sized AH (Amp Hours) rated battery without excessively discharging the battery below 50%.
Battery capacity (Ah or KWh) = (Mileage Requirement / Avg speed) x Avg current or power consumption. Peak Discharge current depends upon the capacity (C) of the battery and the chemistry of the battery or even the quality of the cell used.
Battery size is determined by considering factors such as the power demand of the system, desired battery runtime, efficiency of the battery technology, and any specific requirements or constraints of the application. It involves calculating the required energy capacity and selecting a battery with matching specifications.
Compute battery Watt hours (Amp hour capacity * nominal pack voltage). Then divide the result by the average power consumption of the car, in Watts. The result is the battery life, in hours. So it is: watt-hours / watts = hours. The motor max power does not matter.
Step 1: Collect the Total Connected Loads The first step is the determination of the total connected loads that the battery needs to supply. This is mostly particular to the battery application like UPS system or solar PV system. Step 2: Develop the Load Profile
The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P [W] is the product between voltage U [V] and current I [A]: The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses.
The energy content of a string E bs [Wh] is equal with the product between the number of battery cells connected in series N cs [-] and the energy of a battery cell E bc [Wh]. The total number of strings of the battery pack N sb [-] is calculated by dividing the battery pack total energy E bp [Wh] to the energy content of a string E bs [Wh].

Power Requirements. In any electric motor application, the desired equipment performance dictates the power requirements of the motor. The rated power of the motor is calculated from the combination of speed, torque, and duty cycle of the application that in turn establishes the critical voltage, current, and capacity requirements of the battery.
The relationship between motor power and voltage is influenced by the equation P = U x I, where P represents power, U is voltage, and I is current. For motors with the same power rating, a higher voltage results in a lower current, which means reduced battery discharge current. This leads to longer battery discharge times.
