Convert Amp Hours (Ah) to Kilowatt Hours (kWh)

Use the calculator below to convert Ah to kWh based on your battery's voltage. This is useful for estimating energy capacity, planning electrical system sizing, or calculating the range of electric vehicles and off-grid power systems.

Ah to kWh Conversion Formula

To convert amp-hours to kilowatt-hours, you need to know the voltage of the system. The formula used is:

Where:

• Ah = Battery capacity in ampere-hours
• V = Voltage
• kWh = Energy in kilowatt-hours

This formula is widely used in engineering and energy systems to estimate how much energy a battery or storage unit can deliver over time.

Example: Electric Vehicle Battery Capacity

Let's say an electric car uses a battery rated at 60 Ah and 400 volts. To find the total energy capacity:

This means the vehicle stores 24 kWh of energy, helping estimate its range and charging requirements. This conversion is essential when comparing electric vehicles or evaluating charging efficiency.

Example: Solar Power Battery Bank

In off-grid solar installations, batteries are used to store excess energy for nighttime or cloudy days. Suppose your battery bank has a total capacity of 100 Ah and runs on 24 volts:

This battery setup provides 2.4 kilowatt-hours of usable energy. Knowing this value helps you plan how much power your solar system can store and supply - crucial for ensuring consistent energy availability in homes or remote setups.

Common Use Cases for Ah to kWh Conversion

Ah to kWh conversion is essential across various industries and scenarios. Here are some popular applications:

• Electric Vehicles (EVs): Estimating range, charging times, and comparing battery efficiency.
• Solar Energy Systems: Designing off-grid setups and calculating backup power availability.
• Home Energy Storage: Assessing battery banks for smart home energy management.
• Telecom & UPS: Sizing battery backup systems in server rooms and data centers.

Conclusion: Why Convert Ah to kWh?

Converting amp-hours (Ah) to kilowatt-hours (kWh) is essential for evaluating battery performance in real-world applications like electric vehicles, solar energy systems, and off-grid installations. It helps you estimate energy capacity, manage consumption, and compare system efficiencies.
