Now the wonders are coming: The new electric car batteries can do that
Porsche There are progress in the electric car, especially with the batteries
Site author Wolfgang Gomoll
The batteries are the central element in electromobility. In order to make the highly sensitive energy stores fit for the future, research will be carried out in various areas. Starting from the cells and their production, to cooling to the loading.
For links on this page, Site receives. A commission from the dealer, Z.B. For marked. More information robust is the new buzzword when it comes to batteries and charging it. Because when tinking about the electricity, everything has to fit in order to achieve the times specified in the data sheets, because the batteries are sensitive, especially when it comes to the temperature, which is more than 35 degrees Celsius when it comes to quick charging. This is exactly where the engineers start the lever. "You have to treat the battery like an eyeball," explains Dr. Klaus Rechberger Head of Electromobility, HV integration at Porsche. In order to create the Celsius well-being oasis, the Zuffenhausen people use the existing loss of loss that produce the drives and the various components. The result is that the batteries treated with velvet gloves can be loaded faster even in cold weather.
Fast charging also in the case of cold
The cooling of the batteries is another topic that pays the range of the electromobile. Here the finder Mahle’s resourceful spirits have looked around at the high-performance computer computers and discovered the concept of immersion cooling. With this type of cooling, the large batteries of an electric car are enclosed by a thermal -conducting but not electrically conductive liquid.
Mash E-car battery: with "Immersion" Should they be able to load faster
"Immersion cooling clears the way for a completely new generation of battery systems," says Martin Berger, Head of Corporate Research and Prior Development at Mahle. If this trick works, the batteries can load significantly faster and the shortened electricity tank enables the energy stores to be smaller. In addition, the batteries age slower and even in the event of damage, the liquid coat offers additional protection.
Wunderkus with up to 750 kW charging power?
The Stuttgart supplier sees the loading of the battery holistically. If the batteries are cooled efficiently, you can also screw the charging capacity upwards. To this end, the Swabians want to use the existing infrastructure of their own charging network chargingly with the approximately 1000 charging points. The additional power should provide the electricity filling stations up to 750 kW in the future. That would be a land of milk and honey for the electric mobilists. However, the power grid is not infinitely resilient. That is why the MAHLE charging system controls the load distribution within the power grid intelligently, so that as many electric vehicles as possible can be loaded on the existing network connection at the same time.
Catl Sodium-ion battery from Catl
With the batteries, something is happening. The Chinese cell producer Catl (Contemporary Amperex Technology) is working on a sodium-ion battery. The functional principle of this battery corresponds to that of the lithium ions, but this battery is characterized that they can be loaded quickly even at low temperatures and generally have high thermal stability.

Catl brings sodium-ion batteries
At -20 degrees Celsius, the batteries still have 90 percent of the capacity and can be loaded from zero to 80 percent at room temperature in 15 minutes. The fact that the sodium ions are relatively large and the energy density with 160 WH/kg still remains behind that of top cells that have 270 Wh/kg remains behind the minus side.

The Fraunhofer Institute for Material and Beam Technology IWS is researching a dry coating process to create battery electrodes in an environmentally friendly and cost-efficient manner by dispensing with poisonous solvents. As the name Drytraec already reveals, it is a new dry coating process that does not require a solvent, but instead a special binder is used. With the help of two rotating rollers, one of which rotates faster, a fine coating film forms that is then transferred to a current rod foil. In the last step, the resulting role is cut and the individual parts are stacked accordingly in order to create the finished battery cell.
Bosch Flexible charging cable from Bosch
Charging cables are 40 percent easier
The large supplier Bosch will be released when researching battery cells, but wants to deliver the equipment necessary for production in the future. What the drivers of electric cars should be even more happy about is that the chunky and heavy charging cables belong to the past. The supplier’s technicians have disposed of the charging brick and thus also 40 percent of the original weight. The three-phase cable enables Mode-2 and Mode-3 shop from alternating current with up to 22 kilowatts.

Flux compensator ?
There was an inventor who only needed garbage for the drive. Doc Brown was probably called…. Why not just take on this idea – there is enough garbage, or ? Oh so does not work…..Was only in the film ! Well then the vast majority must continue with their combustion engineer for the time being…..
Yesterday on Wiso
The petrol stations now have to post a comparison of the costs. Also included is electricity and it is particularly cheap in the table. The Ministry of Economic Affairs only used the budgetary flow of homeowners to calculate. Just as if the entire population in their own house would live with solar on the roof. This is exactly what all traffic concepts characterized: the reality of the people is hidden. The majority in the country live in multi -party houses, many for rent. Then it will be sinfully expensive to recharge your batteries on the public charging stations. And so single parents, low earners, poverty pensioners in cramped apartments have to co-finance the electric cars of the privileged, because they also pay VAT too.
@Kalle, nonsense again!
Newest test, Ioniq5 217PS, test consumption 25.5 kWh! Hyundai and EnBW loading tariff together on motorways € 0.48/kWh, does € 12.24/100km. Diesel currently € 1.34/l, gasoline € 1.56/l or. 9.13l diesel or 7.84l petrol. My 4.90m combination 6.3l/100km! Golf VIII TDI 150PS 4.5L test consumption, thus comes more than twice as far as a current. Even my petrol engines get on. But as I said, nonsense!
Our daily miracle ?!
Why are these things always with "Wonder" designated ? Always thought that in these areas it is just called "Technical development" or "progress" "Wonder" are more for the fairy tale book, or ??? Should a new battery actually go into mass production at some point. you will surely be able to read something about it in advance by the manufacturer. Otherwise it is all a lot of hot air from any test laboratories that have nothing to do with reality…..
Now only sweat beads on the forehead of the 1.06% electric car owners should occur if you read reports about the support batteries in the starting blocks. Because this would make all of the electric cars in circulation in one fell swoop, if if "Superaccuse" make them relics of e-past. The sales of electric cars would normally have to collapse if there was something in the actual introduction of new batteries. So we take the messages as a weekly column of the section "Had, could, wanted", But the z.Z. rather belongs in the realm of imagination!
@Kalle, right, nonsense…
…When you look at it. There is no petrol engine that suddenly consumed 2 liters less! But it should be so -called "Wondoma" come that make every current electric car look like, as if it came from the "Stone Age" the electric technology and thus crash in value. But there are enough examples of how you try to talk about the electric cars for all areas!
A new miracle battery every week, the Eauto is reviewed and can pack Tesla. Click Biting! Then some unfinished ideas, prototypes or just brain spider are presented. There are two knowledge: 1. There is still a lot of improvement potential and today’s electric cars are hopelessly outdated and special waste in a few years. 2. The times when you got facts, facts, facts are over
I can only repeat myself…
We let ourselves be carried out by new developments, tries and tests every day. We currently have a climate hysteria and that includes the electric car! But back to the facts: these are all (probably very good) ideas and strategies that are all still in the development stage. It takes a while for you to get from the laboratory to series production. Therefore we have not yet available this technology for the series.- I think of a) number of charging cycles; b) acceptance of performance over the service life; c) battery in winter; d) Behavior of the battery when it comes to quick shops; e) Deleting a burning electric car. All of this must be verified and brought to series production. – In my professional life I saw some interesting idea between development and series dying.
The miracle batteries
The Wunderkus, but has never become ready for series production for years. There are worlds between theory and practice.
And the …
-If this trick works, the batteries can load significantly faster and the shortened electricity tank enables the energy stores to be smaller.- …m then reduces the range again. Just because I find a petrol station on every corner, I don’t refuel every day for 20 euros. I would rather tend to the opposite: I would like to load faster, but still continue to drive 300, 400, 500, 600km!
Wunderkus with up to 750 kW charging power
Where in God’s name should the electricity come from in order to realize up to 750 kW charging power? If, it could be possible, up to etc. and so on. No, especially not if most of our population should really drive Stromer. In my knowledge, thanks to gifted politics, we said goodbye to nuclear power at lightning speed or not? If we have already developed new technologies that can deliver and provide electricity hours to electricity? Around the 43 million cars in D .If only half of it would have electricity here, our EU neighboring countries should build additional nuclear power plants to supply us with electricity. What goes here in the country mocks every description no matter in which color.
Always the same arguments and the consideration of a snapshot. Atom is not a solution and it won’t be either. In the meantime, more and more people have replaced their 100 watt bulbs with LED. already saves a lot of electricity! Where the electricity comes from, there are a lot of experts for. The rules already!
