What is SOH?
Understanding State of Health (SOH). A key metric for electric vehicles
When considering the longevity and performance of an electric vehicle (EV), a crucial term to understand is State of Health (SoH). This metric provides insight into the overall health and capacity of the EV’s battery.
What is State of Health?
SoH is a percentage measurement that reflects the battery’s current capacity compared to its original capacity when it was new. Think of it like a battery health check-up. A higher SoH indicates a healthier battery, while a lower SoH suggests degradation.
Why is SoH Important?
- Range and Performance: A higher SoH means the battery can store more energy, leading to increased range and better overall performance.
- Battery Lifespan: SoH gives you a sense of how long the battery is likely to last. While EV batteries are designed to last many years, their capacity will naturally decline over time.
- Resale Value: A higher SoH can positively impact the resale value of your EV. Buyers often look for vehicles with healthy batteries.
Factors Affecting SoH
Several factors can influence the degradation of an EV battery and, consequently, its SoH:
- Temperature: Extreme temperatures, both hot and cold, can accelerate battery degradation.
- Charging Habits: Frequent full charges and deep discharges can stress the battery.
- Driving Style: Aggressive driving styles can put additional strain on the battery.
Monitoring SoH
Many modern EVs come with built-in systems that monitor SoH and provide information to the driver. You can often access this information through the vehicle’s infotainment system or a dedicated mobile app.
Maximizing Battery Life
To maintain a healthy SoH and prolong the life of your EV battery, consider the following tips:
- Moderate Charging: Avoid charging to 100% or discharging to 0% regularly.
- Temperature Control: Park your EV in shaded areas during hot weather and use a garage or car cover during cold weather.
- Regular Maintenance: Follow the manufacturer’s recommended maintenance schedule.
- Avoid Extreme Temperatures: If possible, avoid charging or discharging the battery in extreme heat or cold.
By understanding SoH and following these tips, you can ensure that your EV continues to deliver optimal performance for years to come.
