Unlocking Your EV's True Power: How to Calculate Real-World Battery Capacity and Health
Demystifying your electric vehicle's battery performance with straightforward methods and essential tools. Key Insights into EV Battery Health Gross vs. Usable Capacity: Understand that your EV battery has a total (gross) capacity and a deliberately limited usable capacity to protect its longevity. Simple Math for Accuracy: Calculate your battery's real capacity by tracking energy consumption (kWh) and percentage of battery used (SoC drop) during a drive or charge. Beyond the Basics with OBD2: Utilize specialized OBD2 apps and dongles for precise, real-time data from your vehicle's Battery Management System (BMS), including State of Health (SoH). To accurately calculate your EV battery's real-world capacity and assess its health, you can track the energy consumed during a drive and the corresponding drop in the State of Charge (SoC). By dividing the kilowatt-hours (kWh) used by the fraction of the SoC percentage change, you can determine an estimated usable capacity. Compar…
