However, it is also one of the hardest to predict. Range depends on a wide range of dynamic variables: driving behavior, road elevation, outside temperature, energy management strategy, and even passenger load.<\/p>\n\n\n\n<p>For OEMs and Tier 1 suppliers, simulation has become a strategic tool to accurately estimate EV range during early development, long before physical testing begins. It enables a better understanding of how each condition affects energy consumption \u2013 helping teams design smarter systems, faster.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why is range so hard to predict?<\/strong><\/h2>\n\n\n\n<p>Unlike internal combustion vehicles, EV range is highly sensitive to external conditions and usage patterns. For example, an urban route with stop-and-go traffic may be more efficient than steady highway driving. Other influential variables include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Battery thermal management (heating or cooling)<br><\/li>\n\n\n\n<li>Use of auxiliary systems like HVAC or infotainment<br><\/li>\n\n\n\n<li>The driver\u2019s style (aggressive vs. economical)<br><\/li>\n\n\n\n<li>Road gradient and vehicle load<br><\/li>\n<\/ul>\n\n\n\n<p>These factors combine in complex, dynamic ways. Without simulation, it\u2019s nearly impossible to understand or quantify their full impact early in development.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>A predictive, multi-variable simulation approach<\/strong><\/h2>\n\n\n\n<p>With a platform like<a href=\"https:\/\/www.avsimulation.com\/en\/scaner\/\"> SCANeR\u2122<\/a>, engineers can simulate how each factor contributes to overall energy usage and range.

The reasons for this include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increased energy draw from cabin heating systems<br><\/li>\n\n\n\n<li>Reduced battery efficiency in low temperatures<br><\/li>\n\n\n\n<li>Lower regenerative braking performance<br><\/li>\n<\/ul>\n\n\n\n<p>Simulation allows engineers to quantify and isolate these effects, and explore solutions such as battery preconditioning or energy recovery improvements\u2014before physical testing even begins.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Optimizing energy management strategies<\/strong><\/h2>\n\n\n\n<p>Simulation also helps validate and improve onboard energy management strategies (EMS).
