Calculating the Input Energy for Leaf Battery Pack from a Power Plant

Click For Summary
SUMMARY

The discussion focuses on calculating the input energy required for a leaf battery pack powered by a standard power plant, specifically under the constraints of a maximum efficiency of 25%. The formula provided for this calculation is Input Energy = Output Energy / Efficiency. Participants emphasize the necessity of knowing the energy consumption rating of the vehicle to accurately determine the energy needed to travel one mile. The conversation highlights the importance of understanding both the efficiency of energy conversion and the specific energy consumption metrics of electric vehicles.

PREREQUISITES
  • Understanding of energy efficiency concepts
  • Familiarity with electric vehicle energy consumption ratings
  • Basic knowledge of kilowatt-hour (kWh) as a unit of energy
  • Awareness of power generation and transmission processes
NEXT STEPS
  • Research the energy consumption rating for specific electric vehicles
  • Explore the principles of energy efficiency in power generation
  • Learn about the conversion of AC to DC electricity in battery systems
  • Investigate the impact of efficiency on overall energy costs in electric vehicles
USEFUL FOR

Electric vehicle engineers, energy analysts, and anyone involved in optimizing battery performance and energy consumption in electric transportation systems.

if the electrical energy stored in the leaf's battery pack came from a standard power plant and was delivered by a utility company ( like United Illuminated or Connecticut light and power) it was generated, transmitted, and transformed to the DC electricity that a battery can store at no more than 25% overall efficiency. Estimate how much energy in kilowatt-hours is consumed by the power plant (input energy) to let the leaf go one mile on the gollowing equation:

Input energy= output energy/efficiency

please help!

You'll need to know the energy consumption rating for the car in order to determine the energy required to go one mile. Do you have that value?
