How to Calculate EV Charging Efficiency in Bangladesh? (Practical Tips)

Electric vehicle charging may seem simple, but knowing how much energy actually gets stored in your battery helps you save money and understand how your EV performs. If you’re curious about how to measure this, keep reading for a clear step-by-step guide.

Step 1: Start Charging

Plug your EV into the charger and begin a normal charging session. Make sure the charger is functioning properly and connected to a stable power source. Choose a location where you can easily note the numbers from the charger or meter. Avoid charging during extreme heat, as it can affect performance. Stay close if you’re planning to take measurements manually.

Step 2: Record Grid Energy

Use a power meter to keep track of how many kilowatt-hours (kWh) are drawn from the grid when the car is charging. You will find your input energy on the display of some home chargers. If you are at a public charging station, look at the receipt or display to see how much energy you have used. Be sure to note the full value for the entire session on the receipt.

Step 3: Check Battery Energy

When the charging is complete, look at your EV’s dashboard or use a battery diagnostic app to see how much energy went into the battery. This value is your output energy. Not all cars show this clearly, so use the most accurate reading available. This is the energy your battery actually stored from the session. Try to take this reading right after charging ends.

Step 4: Use the Formula

Now it’s time to apply the formula:
Charging Efficiency (%) = (Energy Added to Battery / Energy Drawn from Grid) × 100
For example, if the battery stored 24 kWh and the charger used 30 kWh, then the efficiency is (24 ÷ 30) × 100 = 80%. This tells you how much energy was saved and how much was lost during charging.

Step 5: Review the Result

You should take a moment to review what you have calculated after you have done it. If you have an efficiency of 80%, it means 20% of the electricity has been lost as a result of heat and cooling. 85% and above are excellent numbers. Anything below 70% means that your charger or battery is malfunctioning. The results may vary depending on the type of charger and other factors.

Step 6: Consider Charger Type

Different chargers work differently, so there are differences between them. Often, level 1 chargers are not as fast and as efficient as level 2 chargers, which are faster and use less energy. DC fast chargers are fast, but they can also waste a little more power during charging. It is important to note that the type of charger you use has a significant impact on the efficiency of your device.

Step 7: Check Temperature

It is possible for your car’s efficiency to be reduced if you charge it in high heat, because the battery needs to cool down, and that requires additional energy. If possible, charge in the early morning or at night when it’s cooler. Charging in shade is also helpful in preventing too much heat. Chargers that are charged under cooler conditions tend to perform better.

Step 8: Note Auxiliary Loads

As your EV is charging, it might use energy to run other things like cooling fans or lights. These are known as auxiliary loads and they are a type of load that uses the charger’s energy to operate. As a result, not all of the energy goes to the battery. Keeping the air conditioner off while charging can help reduce the amount of extra energy used, resulting in a more efficient charging process.

Step 9: Try Local Solutions

There are more EV owners in places like Dhaka and Chattogram who are paying closer attention to how and where they charge their vehicles. Using a charging station with a smart monitoring system makes understanding the energy flow and calculating efficiency easier. Among the popular options, Crack Platoon EV charging solution is often recognized in Bangladesh for offering stable sessions and easy-to-read energy usage stats.

Calculating EV charging efficiency is not hard when you follow these simple steps. It helps you understand how well your charger and battery work together. You only need two numbers and a formula to find the result. Try it yourself next time you charge your car to see how efficient it really is.
