A Tesla Model 3 performance for example will discharge roughly 4C with an 82 kilowatt hour battery will discharge at 343 kilowatts peak, so it would drain itself four times in an hour. These already have significant cooling and thermal management challenges however, compare that to the new F1 power unit battery, operating at above 300C. They have to completely charge and discharge several times per lap for hours at a time whilst managing their temperature and not losing performance. With 2026 R1, Ansys Fluent allows for the simulation of battery thermal management with the powerful GPU solver, allowing for rapid assessments of battery performance under various conditions and the cooling requirements. Thermal abuse models can also be included to assess the performance degradation over the life of the battery and cells in their harsh environments.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c418f0c elementor-widget elementor-widget-image\" data-id=\"c418f0c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"2560\" height=\"1627\" src=\"https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2.jpg\" class=\"attachment-full size-full wp-image-7297\" alt=\"\" srcset=\"https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2.jpg 2560w, https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2-300x191.jpg 300w, https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2-1024x651.jpg 1024w, https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2-768x488.jpg 768w, https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2-1536x976.jpg 1536w, https:\/\/www.leapaust.com.au\/blog\/wp-content\/uploads\/2026\/03\/HighResBattery2-2048x1302.jpg 2048w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5fe50c2 elementor-widget elementor-widget-text-editor\" data-id=\"5fe50c2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><em>Simulated thermal steady state of battery cells and module with no cooling measures<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-955118c e-flex e-con-boxed e-con e-parent\" data-id=\"955118c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6636a8d elementor-widget elementor-widget-text-editor\" data-id=\"6636a8d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>ABC News took a deep dive into the new F1 changes in a <span style=\"text-decoration: underline;\"><a href=\"https:\/\/www.abc.net.au\/news\/science\/2026-03-05\/science-behind-2026-f1-car-designs-and-regulations\/106327216\" target=\"_blank\" rel=\"noopener\">recent article<\/a><\/span>, quoting Mercedes F1 team representative Bradley Lord, who stated, <span data-teams=\"true\">&#8220;In pure acceleration terms, they are quicker.
