✍️Calculations: Accumulator

Determine the maximum flight time of an aircraft using lithium-ion batteries. What energy capacity does a battery need to provide a half-hour flight?

• Maximum battery voltage: 50,4 V

• Minimum battery voltage: 36 V

• Total internal resistance of the battery: 40 mega ohm

• Capacity at discharge rate 0,1С: 22000 mAh

• Average total power of aircraft engines: 6,3 kW

• Assume that the battery voltage decreases linearly and the internal resistance of the battery is constant
