Real-world battery usage and vehicle efficiency assessment
The range of an electric vehicle varies significantly based on the road and driving conditions encountered in the real-world. The total energy required to propel a vehicle and the total energy that can be regenerated is based on the quantities of kinetic factors of the whole vehicle under real-world conditions: rolling resistance, aerodynamic drag, gradient resistance, and inertial resistance.
The actual power of the vehicle and its overall holistic efficiency can be calculated using data from the vehicle CAN and GPS. Data obtained from a large fleet of vehicles may be combined in
nCode GlyphWorks to identify the various design usage profiles and determine a 95% target customer. By understanding trends in the overall vehicle efficiency over time, better prognostic models can also be calculated to improve the real-world reliability of the vehicle and maintain its State-of-Health (SOH).
