EVs: Batteries on Wheels - The Importance of Due Diligence
Download MP3Key Difference Between Electric Vehicles (EVs) and Gasoline Vehicles
- EVs and traditional gasoline cars may look similar but have key differences in their makeup.
- EVs typically have a sleek design with a pointed nose and no grille, as they don’t need airflow to cool an engine.
- When purchasing an EV, you're primarily buying a battery with a body around it, not just a traditional car.
Understanding the Battery in an Electric Vehicle
- The battery is the most expensive and important part of an EV, unlike traditional vehicles where the engine and drivetrain are the key components.
- EVs have fewer moving parts compared to gasoline vehicles, making the battery the heart and soul of the car.
Battery vs. Gasoline Engine Longevity
- Gasoline engines tend to run reliably for a long time until they break, while EV batteries gradually degrade over time, affecting their range.
- For example, an EV with a 200-mile range may have only 160-170 miles of range after a few years.
EV Battery Warranty and Degradation
- Most EV batteries come with an 8-year warranty, but there are mileage limitations (e.g., 100,000 miles).
- After the warranty expires, the battery may degrade and hold less charge, affecting the car’s overall range.
Used EVs and Battery Testing
- When buying a used EV, ensure the battery is thoroughly tested, as there are no outward signs of degradation like with a gasoline engine.
- Unlike a gasoline engine, a worn-out EV battery doesn’t make noise or smoke, so proper testing is critical to assess its condition.
Conclusion: Focus on the Battery
- Whether purchasing new or used, prioritize the battery’s reliability and condition when buying an EV.
- Always conduct due diligence on the battery, as it’s the key to performance and longevity in electric vehicles.
