Introduction

Understanding how long a 100 kWh battery can power a house is critical in evaluating the feasibility of battery systems for residential energy needs. This article examines the battery capacity, average residential energy consumption, and associated factors to derive a realistic estimate.

Battery Capacity and Home Energy Consumption

A 100 kWh battery can store a significant amount of energy, and its ability to power a house depends on the average energy consumption of the household. In the United States, the average home uses approximately 30 kWh per day, although this can vary based on location, home size, and lifestyle.

Calculating Battery Duration

To calculate how long a 100 kWh battery can power a house, divide the battery capacity by the average daily consumption. Assuming a consumption of 30 kWh per day:

100 kWh / 30 kWh/day = 3.33 days

This calculation indicates that under ideal conditions, a 100 kWh battery could power the average home for approximately 3.33 days.

Factors Affecting Battery Duration

  • Energy Usage Patterns: Peak usage times and energy-intensive appliances can reduce battery efficiency.
  • Battery Efficiency: Not all stored energy is usable. Efficiency rates can range from 85% to 95%, affecting the net usable capacity.
  • Temperature: Performance can degrade in extreme temperatures, impacting battery life.
  • Degradation Over Time: Battery capacity may decrease with usage over time, reducing the duration it can sustain a household.
