Immersion cooling, a new revolution in batteries/Refrigeración por inmersión, nueva revolución en las baterías

We have already commented several times in this medium about the problem posed by recharging in electric vehicles that run on batteries, when we have to refuel our car to continue the journey, the barely 10 minutes it takes to refuel the internal combustion engines are a great advantage compared to to the hours it would take us to recharge the battery.

Ya hemos comentado varias veces en este medio el problema que supone la recarga en los vehículos eléctricos que funcionan con baterías, cuando tenemos que repostar nuestro automóvil para proseguir viaje, los apenas 10 minutos que nos lleva repostar los motores de explosión son una gran ventaja frente a las horas que nos llevaría recargar la batería.

To recharge electric vehicles, it is not enough to increase the diameter of the fuel hose as they do in formula 1, each time a battery is charged the flow of electrons itself generates a large amount of heat that we have to dissipate in some way if we don't want to run out of battery in a couple of recharges.

Para recargar los vehículos eléctricos no es suficiente con aumentar el diámetro de la manquera del combustible como hacen en la fórmula 1, cada vez que se carga una batería el propio flujo de electrones genera gran cantidad de calor que de alguna manera tenemos que disipar si no queremos quedarnos sin la batería en un par de recargas.

If we want to reduce the charging time we will have to increase the intensity of the current that generates more heat, so we have to adapt the intensity of the load to the type of battery and how it dissipates heat, today we have two types of cooling : by air and by water-based coolant with some additive.

Si queremos disminuir el tiempo de carga tendremos que aumentar la intensidad de la corriente lo genera mas calor, por lo que hemos de adecuar la intensidad de la carga al tipo de batería y a como esta disipa el calor, hoy en día tenemos dos tipos de refrigeración: por aire y por líquido refrigerante a base de agua con algún aditivo.

The more expensive models of the high ranges of companies such as Porsche or Mercedes use complex liquid cooling systems to withstand high intensity loads to shorten recharge times but, the affordable models that are within our reach are cooled by air which is a lot less effective at dissipating heat so recharge times skyrocket.

Los modelos más caros de las gamas altas de compañías como Porsche o Mercedes utilizan complejos sistemas de refrigeración por líquidos para soportar cargas de alta intensidad para acortar los tiempos de recarga pero, los modelos asequibles que están a nuestro alcance están refrigerados por aire que es mucho menos eficaz disipando el calor por lo que los tiempos de recarga se disparan.

This is where immersion cooling makes its appearance, a technique that the most geeks used for a long time to cool their PC's, the invention consists of immersing the same batteries in the cooling liquid, a liquid incapable of conducting electricity but very effective dissipating the heat given off by batteries during charging.

Aquí es donde hace su aparición la refrigeración por inmersión, una técnica que ya usaban hace tiempo los más frikis para refrigerar sus PC's, el invento consiste en sumergir las mismas baterías en el líquido refrigerante, un líquido incapaz de conducir la electricidad pero muy eficaz disipando el calor que desprenden las baterías durante la carga.

This system allows direct contact with the heat source so it is easier to control the heat sources and stabilize the battery if any of the cells fails, with this not only can the intensity of the recharge be increased to shorten the time but also will also allow to increase the performance of the vehicles in acceleration and speed without compromising the battery.

Este sistema permite un contacto directo con la fuente de calor por lo que es más fácil controlar los focos de calor y estabilizar la batería si alguna de las celdas falla, con esto no solo se puede aumentar la intensidad de la recarga para acortar el tiempo sino que además permitirá aumentar las prestaciones de los vehículos en aceleración y velocidad sin comprometer la batería.

Hola @mauromar, que bien cada día mejoran más…

Y si tienen dos baterías así dejas una en casa cargando.

Your articles are interesting about technology and your advances in terms of the vehicular system. Thank you.

I knew something new from your blog. Thank you so much.

Thanks for sharing this important information.

I like to read your blogs because your blogs are very knowledgeable.

Hello @mauromar
I think this you comment could be a big plus point for electric trolley technology. And if this aspect improves significantly we will surely see more electric cars in the coming years. Which will undoubtedly be very beneficial for the planet in general.
For now I can tell you that here in Bogota I have seen only one electric truck, yes many electric bicycles, but no electric cars, none.

There are not many electric cars here either, but it is a matter of time, in northern Europe they hardly sell internal combustion engine cars anymore.

Hello @mauromar, The most computer geeks and me watching youtube videos of how to make refrigeration by immersion hahaha, well I tell you friend that now also used in the mining sector of cryptocurrencies, in fact the liquid is scarce for the same reason

dc current are bringing a revolution in car technology.

That sounds better than the battery, thanks for sharing.

It will help to enhance electric vehicles very much. Thanks for the information.

Learn something new from you.

If it can reduce the heat, then it will increase the battery life of every electric vehicles.

HOLAAAA..

me gusto este ;-)
