EV-battery – Superhero of the future

posted in: Tech, Uncategorized | 0

Electronics have always been one of my great passions. Today I am lucky to work in the field of electronics and digital devices as a computer specialist. Technician by day, eczema healing guide at night. That is a great life :-).

On top of that I often see guys in my field of work that struggle with skin problems. If that is the case for you then the rest of this site is also for you.

I like to think about how the world will look like in 10-20-30 years. Especially with focus on how the technologies will keep transforming our societies. It is here I forsee the EV-battery as a fundemantal part of our infrastructure and transportationsystem. But also spilling into areas that we can’t imagine now.

Okay, on with the subject of EV’s and the lifecycle of their batteries and their many future applications in society.


First and foremost it is important that we take care of mother Earth as we evolve into a digitally dependant civilization. Our dependency on nature is not something we think about every day. But what good is it to get healthy and eczema-free if the planet is being destroyed by our lifestyle?

I think the electric revolution will spill into every part of our lives. Especially with the large numbers of batteries that are produced now and in the future. They will be of great value and have longer lifecycles than is the case now.

Their ability to store energy and act as a buffer will be used in many new applications. For that reason, I will tell about the my ideas of how we will see the area of batteries emerge in the comming decades. It is meant as an inspiration for people that are not that into tech and to open people’s eyes to the possibilities in batteries.

The main focus will be the repair and reuse of batteries. In a couple of years there will be extreme amounts of batteries that are still usable, but not for the application where they started their life. In the following we will look into the usecases of used, but still useable batteries.

This video explains the current situation about recycling of old batteries.


EV’s

As more and more EV’s come onto the roads it will be increasingly important to be able to fix and repair EV batteries.

Now electronics have been integrated into every part of our lives and our cars are rolling computers. The transition from ICE-vehicles to EV’s will be a cornerstone in the evolution of modern western countries. These vehicles are packed with electronics that all run on batteries.

The battery in an EV is the most expensive and environmentally problematic single part. It alone makes the production of a typical EV 74% more energy demanding than the production of a similar conventional car. On top of the energy demand during battery production, there is also a massive need for rare-earth minerals inside the battery itself.

To mitigate these dilemmas the need for efficient battery repair will be a necessary part of the future car market. By repairing instead of replacing an EV battery it is possible to save energy and materials that would otherwise go into the production of a brand new battery. It is also quite certain that the material- and production supply chain will be hard-pressed in the coming decade.

Research into the possibility of repairing a faulty battery pack shows it is possible to replace only a small part of the battery. Often it is only a few faulty cells that make the entire battery defective. These cells can be replaced by new cells that have the same characteristics as the original cell. Thereby reducing the cost of replacing the entire battery pack.

Another interesting aspect of battery repair is using old cells with sub-nominal capacity in low-demand applications. This could be power grid backup installations or as powerwall in your house. The areas of application of these used cells are vast.


Electric ships

Used cells have low capacity and their power-to-weight ratio is low. But in a ship, they could be used as ballast and at the same time act as a power source. Solar cells on the surfaces and superstructure of the ship would harvest the sun’s energy and store it in the ballast battery pack.

This ship is a fully electric ship and in the future, this kind of ship could be build using used cells from used EV battery packs.

By reusing old battery cells the EV battery repair industry will be able to lower their prices, since the used cells may be a resource instead of going to waste. This will profit both EV consumers and the business itself, but also the environment. The cells go through one more useful application, but recycling of the materials might be the last option.
