It charges very quickly, has excellent efficiency, and promises to reduce its carbon footprint by half compared to today's European EVs, but the really important part is the fluid that makes it work.</p><p>The big innovation with this one-off study is how it cools its battery, which is completely different from how everybody else does it. It features a cooling system that, unlike in most other EVs, where the battery cells are indirectly cooled, uses a different coolant that can safely come into contact with high-voltage parts.</p>            <section>                            <div>                    <h2>                        Gallery: Shell Recharge                    </h2>                </div>                            <div>                                                                                                                                                        <div>                                                                                                                                                                                                                                                                                                <div>                                                                                                                                                    4                                </div>                                                    </div>                                        <div>                                                                                                                        <span>                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     </span>                                                                                        <span>                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     </span>                                                                                        <span>                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     </span>                                            </div>                                            <div>                            Source: Shell                        </div>                                                        </div>    </section><div></div><p>This means the battery cells are directly immersed in the fluid, so heat can be extracted more quickly and efficiently. Improved heat extraction offers multiple benefits, including greater control over cell temperature. This is especially useful during fast charging, when cells tend to heat up, forcing the car to reduce charging power to protect the pack.</p><p>It’s a simplified single-circuit cooling system, which also handles heat extraction from the motor and electronics. This reduces the complexity of the cooling system, making the vehicle lighter and cheaper, and ultimately boosting its efficiency.</p><p>Shell says its EV can charge its battery pack, of unspecified capacity and chemistry, from 10% to 80% in under 10 minutes from a 175 kW charger. It adds range at a rate of 15 miles (25 km) per minute, which Shell says is better than the average of 8 miles (13 km) of other EVs charging at the same power.</p><div><div id="ads_6122441_EV_ev_us_Rectangle_rectangle_1_1782491430"></div></div>    <section>        <div>            <img src="https://imageproxy.pbkrs.com/https://cdn.motor1.com/custom/share/evus_newsletter_widget_logo.svg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" alt="Motor1.com INSIDER - logo" original-src="https://imageproxy.pbkrs.com/https://cdn.motor1.com/custom/share/evus_newsletter_widget_logo.svg"/>        </div>        <div>            <div>Stay informed with our newsletter every weekday</div>                        <div>                <div></div>                back            </div>                                             Subscribe                <span class="widget-newsletter__legal">For more info, read our Privacy Policy &amp; Terms of Use. </span>                    </div>    </section><p>The vehicle also boasts a claimed running efficiency of 6.2 miles/kWh (10 km/kWh), although Shell doesn’t specify whether it used a standard test cycle such as EPA or WLTP.

Their appeal in a combustion car is that they don’t boil easily, create little pressure, reduce corrosion, and can prevent local hot spots, but they’re expensive and aren't as good as water-based coolants at heat transfer.</p>                                                                                                                                                                                                                                                        <section><p><span>We want your opinion!</span></p><div><p>What would you like to see on Insideevs.com?</p>Take our 3 minute survey.</div><p>- The InsideEVs team</p></section>                                                                            <div>                                <div>                                    Share this Story                                </div>                                <div>                                    <ul>                            <li>                                                                                                                                            Facebook                                                                        </li>                                    <li>                                                                                                                                            X                                                                        </li>                            <li>                                                                                                                                            LinkedIn                                                                        </li>                            <li>                                                                                                                                            Flipboard                                                                        </li>                                                    <li>                                                                                                                                            Reddit                                                                        </li>                            <li>                                                                                                                                            WhatsApp                                                                        </li>                            <li>                                                                                                                                            E-Mail                                                                        </li>                                                                                    <li>                                                                                                                                                 copy                                                                        </li>                    </ul>                                </div>                                                                    <div>                                        <div>                                                                                                                                                                                    <span class="top-counter-comments-label">GO TO COMMENTS</span>                                                                                            <div>                                                    <span>(</span>                                                    <div></div>                                                    <span>)</span>                                                </div>                                                                                    </div>                                    </div>                                                            </div>                                                            <div>                                    <div>                                        <span>Got a tip for us?

SHEL

SHEH

<p>Shell unveiled the Triple 10 EV concept, featuring a novel direct battery cooling system using dielectric coolant. While Shell has no plans to manufacture vehicles, it aims to license this technology and sell its specialized thermal fluid to automakers. The system enables ultra-fast charging (10-80% in under 10 minutes) and improved efficiency by directly immersing cells in non-conductive fluid, offering a new revenue stream for the oil giant in the electric vehicle era.</p>
