Battery Degradation
What is it?
Battery degradation is the natural, gradual loss of a battery's maximum capacity and power output over time and usage. It means that a battery which originally held 100 kWh might only hold 90 kWh after several years.
How it works
Degradation occurs due to chemical and physical changes inside the lithium-ion cells. Every time a battery is charged and discharged (a cycle), microscopic wear occurs. Real-world data from over 22,000 EVs shows an average capacity loss of about 2.3% per year. Factors that accelerate degradation include frequent DC fast charging, consistently charging to 100%, leaving the car at a very low State of Charge, and exposure to extreme heat.
Why it matters
Degradation directly impacts your vehicle's maximum range and its resale value. While modern EV batteries are designed to outlast the car itself, minimizing degradation through smart charging habits can preserve thousands of dollars in vehicle value and ensure you don't lose crucial miles of range.
The Aximote Advantage
Aximote helps you protect your battery by providing total transparency over your charging habits. By tracking every charging session natively, Aximote allows you to monitor your charging behavior. By understanding your true daily energy needs through Aximote's trip logs, you can confidently set your daily charge limit to 80%, knowing exactly how much range you actually require, thereby actively slowing down battery degradation.
