New battery technology is making waves in the electric vehicle (EV) landscape, particularly with the Renault Megane E-Tech. Thanks to Total Energies Lubrifiants, this innovative vehicle has been fitted with an immersion-cooled battery that utilizes a groundbreaking fluid known as Cell Shield. The results? Charging times have been halved, and the vehicle’s range has seen a 6% boost. Let\u2019s dive into what this all means and how it could shape the future of electric driving.<\/p>\n

How Does Immersion Cooling Work?<\/p>\n

At its core, immersion cooling is about reducing heat by submerging components in a fluid. While that sounds straightforward, it\u2019s a bit more complex when it comes to electronics. For instance, introducing water to electrical circuits can lead to disastrous short circuits. That\u2019s why EV batteries are designed to be waterproof. <\/p>\n

In traditional combustion engines, heat is transferred through metal walls into water flowing through channels. This water then moves to a radiator, where it\u2019s cooled by air. It\u2019s a similar concept to immersion cooling, where heat is dissipated directly from hot components into a cooling medium. <\/p>\n

In the realm of electronics, heat is typically managed by transferring it to the air or using heat sinks. However, immersing components in a dielectric fluid\u2014one that doesn\u2019t conduct electricity\u2014offers a more efficient solution. This method has been used in power distribution systems for years, but its application in EV batteries is a relatively new frontier.<\/p>\n

What Makes Cell Shield Special?<\/p>\n

The challenge with immersion cooling lies in developing the right fluid. Total\u2019s Cell Shield is designed to flow through battery cells without conducting electricity, allowing for direct heat transfer from the cells into the fluid. This not only enhances cooling efficiency but also simplifies the overall design of the battery system. <\/p>\n

Interestingly, immersion cooling can lead to lighter battery packs since some of the traditional components used in liquid-cooled systems can be eliminated. This means that not only do we get better performance, but we also get a more streamlined design.<\/p>\n

The Journey to the Megane E-Tech<\/p>\n

Total Energies didn\u2019t just stumble upon this technology overnight. The development of the immersion-cooled battery for the Megane E-Tech was the result of years of research and collaboration with British engineering firm Ricardo. Their work began with a prototype for a Volvo XC60 plug-in hybrid back in late 2020. <\/p>\n

The findings were promising: immersion-cooled batteries not only provided superior cooling and faster charging times but also fit well within existing vehicle architectures. They were found to be 6% cheaper and lighter than traditional battery systems. <\/p>\n

Safety is another critical aspect. The new fluid has shown remarkable capabilities in suppressing thermal runaway and internal fires, which are significant concerns in the EV industry. This advancement could lead to greater consumer confidence in electric vehicles, making them a more appealing choice for a broader audience.<\/p>\n

What This Means for the Future of EVs<\/p>\n

The implications of this technology extend beyond just the Renault Megane E-Tech. As manufacturers look to improve charging times and vehicle ranges, innovations like immersion cooling could become standard in the industry. Faster charging means less time at the charging station and more time on the road, addressing one of the biggest concerns for potential EV buyers: range anxiety.<\/p>\n

Moreover, the lighter and more efficient battery systems could lead to a new generation of electric vehicles that are not only more powerful but also more environmentally friendly. With reduced manufacturing costs and improved safety, we might see a significant shift in how electric vehicles are perceived and adopted.<\/p>\n

The big takeaway? Embracing innovations like immersion cooling isn\u2019t just about enhancing performance\u2014it\u2019s about reshaping the entire landscape of electric mobility. If you\u2019re considering making the switch to an EV, keep an eye on these advancements. They could very well change the game for electric driving in the near future.<\/p>\n","protected":false},"excerpt":{"rendered":"

New battery tech has improved Megane EV\u2019s range and charging times<\/p>\n

\n

Total Energies Lubrifiants, the lubricants arm of French energy giant Total, has fitted\u00a0a Renault Megane E-Tech<\/a> with an immersion-cooled battery that uses a new fluid called Cell Shield \u2013 and is claimed to have halved the EV\u2019s charging<\/a> times and extended its range<\/a> by 6%.<\/p>\n

Immersion cooling is a conveniently obvious term: reducing the temperature of something by putting it into a fluid.<\/p>\n

But where electrical components are concerned, that\u2019s not as simple as it sounds, as introducing water-based fluid to the circuitry of any electrical device causes a short circuit and instant destruction. This is why EV batteries are waterproof.<\/p>\n

In a combustion engine, heat is conducted through the walls of the cylinders and combustion chambers into water flowing through channels. That water passes through the radiator (a heat exchanger) and is taken away by cool air passing through it.<\/p>\n

It\u2019s a form of immersion cooling in that heat is transferred directly from the hot metal of the engine to the water\u00a0in the cooling system.<\/p>\n

In electronics, heat is either transferred directly to the air or, with components that get very hot, such as a computer processor chip or EV battery cell, transferred to a heat sink that in turn is cooled by either air or a liquid.<\/p>\n

Both are effective methods, but immersing the hot component in a cooling fluid is more so.<\/p>\n

A special fluid is needed, however. In electronics, a dielectric fluid is one that doesn\u2019t conduct electricity. This isn\u2019t a new concept, having been used in power distribution equipment\u00a0like transformers for many years, mainly as a special type of electrical insulator.<\/p>\n

EV battery cells are usually mounted on a heat sink through which coolant flows but doesn\u2019t actually come into contact with the cells. Submersing them fully or partially in a dielectric fluid is more effective, because it conducts heat away directly from the\u00a0cells into the fluid.<\/p>\n

The complexities lie in developing the right fluid\u00a0to flow through the cells. Weight is also a consideration, although immersion cooling means other components that carry fluid in liquid-cooled batteries can be ditched.<\/p>\n

Total\u2019s Megane battery is the result of several years of work on immersion cooling technology. It hired British engineering firm Ricardo to develop a prototype of such a battery for a Volvo XC60<\/a> plug-in hybrid<\/a> in late 2020.<\/p>\n

Apart from superior cooling and faster charge times, Ricardo concluded that immersion-cooled batteries would fit in existing vehicle architectures, cost 6% less and be lighter.<\/p>\n

One more important factor is further improved safety. Promisingly, testing has proved Total\u2019s new fluid is \u201cunprecedentedly\u201d good at suppressing thermal runaway and internal fire.<\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":62643,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"Default","format":"standard","meta":{"footnotes":""},"categories":[2,137],"tags":[],"class_list":["post-62642","post","type-post","status-publish","format-standard","has-post-thumbnail","category-featured","category-news"],"_links":{"self":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/62642","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/comments?post=62642"}],"version-history":[{"count":0,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/posts\/62642\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media\/62643"}],"wp:attachment":[{"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/media?parent=62642"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/categories?post=62642"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.globalvillagespace.com\/tech\/wp-json\/wp\/v2\/tags?post=62642"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
