It feels good to own a hybrid vehicle. You’re saving money on gas and leaving less of a carbon footprint. But like any vehicle, hybrids need proper care—in fact, even more care—to keep running efficiently. Hybrid batteries are built to last the life of the vehicle. However, they are still prone to malfunctions and failures just like any automotive component.
Here are some of the most common signs that your hybrid vehicle battery isn’t working right:
1. A Drop in MPG
Numerous issues can affect your vehicle’s fuel economy, but a weak hybrid battery will certainly affect your miles per gallon (MPG). If you notice a steady drop in your MPG, it could be the battery.
2. State of Charge Fluctuations
If your state of charge (SOC) is fluctuating wildly, it’s either a battery issue or a problem within the charging system.
3. Increased Use of Internal Combustion Engine
If you notice that your Internal Combustion Engine (ICE) is running more than usual, there could be a problem with your hybrid battery.
4. Decreased Battery Charge
If your battery charge goes down when the vehicle is not in operation, then there is likely some sort of issue with the battery or charging system that you will want to have looked at by a professional mechanic who understands hybrid vehicles.
5. Strange Engine Noises
The more your internal combustion engine runs, the more likely it is to experience its own issues. You may hear strange noises or the car struggles to accelerate. This is an example of a failing hybrid battery leading to overuse and damage within the ICE.
