6 FAQs about [How to calculate the power of the battery with motor]

How do you calculate the run time of a battery?

To calculate the run time of a battery, the following formula is used: Battery Capacity in mAh: The total charge the battery can hold, measured in milliampere-hours (mAh). Battery Voltage in V: The nominal voltage of the battery. Device Power Consumption in watts: The power consume by the device being power by the battery, measure in watts.

How do you convert a single battery to a motor?

If you could convert the single battery's voltage to motor voltage at 100% efficiency (& you cant) then current at current = Power/Volts = 8200W/3.2V =~ 2500 A. (!!!!) . 10 cells in series give you 10 x the run time (30+ minutes) at 1/10th the current (250A) and you are beginning to get realistic. Beginning.

What determines the power requirements of an electric motor?

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.

How do you calculate battery capacity?

The standard measure for battery capacity is milliampere-hours (mAh) or amp-hours (Ah), which indicates how long the battery will last based on the current it outputs. The calculation of the battery life at a certain current draw is the battery capacity (Ah) / output current (A) = battery life (hours).

How do batteries measure their capacity?

Batteries measure their capacity in milliamp hours, mAh. This states how many hours the battery can supply 1 mA of current, or how many mA of current it can supply for one hour. The current draw depends on the motor, for this, we can refer to the datasheets found on the product pages.

How do you choose a battery for a motor?

An essential criteria in battery selection is making sure that the battery will not only supply the motor’s voltage and current requirements when fully charged, but also continue to meet those requirements as it approaches full discharge.
