Enter the battery current (amps) and the battery resistance (ohms) into the calculator to determine the Battery Voltage. Need help? Ask our AI assistant The following formula is used to calculate the Battery Voltage. Variables: To calculate the battery voltage, multiply the battery current by the battery resistance.
Suppose a battery has an internal resistance of 0.3 ohms, and the battery voltage is 0.9V. Calculate the current flowing through the battery. Given: V b (V) = 0.9V, R b (Ω) = 0.3 Ω. Battery voltage, V b (V) = I b (A) * R b (Ω)
The required battery pack total energy E bp [Wh] is calculated as the product between the average energy consumption E avg [Wh/km] and vehicle range D v [km]. For this example we’ll design the high voltage battery pack for a vehicle range of 250 km. The following calculations are going to be performed for each cell type.
The energy content of a battery, measured in watt-hours (Wh), is calculated by multiplying voltage by capacity. Series Connection: Batteries connected end-to-end, increasing total voltage while maintaining the same capacity.
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.
This is the total Amp-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage. Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate.
