What’s in an EV battery?

Fortune favours the fold. Folding led to origami, one of the world’s most unique and celebrated art forms. It also sees use in EV batteries, folding modules to maximise storage while taking up minimum space. Because naturally, EV batteries contain more than the battery modules themselves.

Given that batteries take centre stage in the electric mobility revolution, it’s natural to wonder what they’re made of. A battery pack contains two main components: battery cells, and a Cell-Module Controller (CMC) which controls all information and functions of the battery like voltage, current, and temperature by controlling the CMC and other parts.

The cells themselves are made up of cathodes, anodes, separators, and electrolytes. The folding begins by stacking the cathode, anode, and a separator together. In a mixing process, the raw materials are combined and used to coat copper and aluminium foil to ensure proper electric flow within the cell.

Cells are packaged differently. Prismatically, in a pouch, or as a cylinder. Each type has some strong and weak points when it comes to productivity, cost, and safety.

Folding opens up new avenues, both in the arts and in battery technology. Proving conclusively that a fold move is the right move.

When in Rovaniemi

Do as the locals do. Words of wisdom that any seasoned traveller is familiar with. They don’t just govern behavior, however. They speak to the importance of having an open mind, embracing new customs, and adapting to one’s surroundings. There are equivalents in all languages. In English, one is told that “when in Rome, do as the Romans do”. It counts for the Italian capital, just as it counts for northern Finland. Which is exactly where we headed this winter.

Road to Ronda

Achieving the perfect driving experience is dependent on two things. Firstly, the car needs to provide optimal speed, comfort, and handling so one can really feel the thrill of driving.
