Manufacturing Process of Electric Vehicle Batteries | Full Factory Tour

Описание: Ever wondered how electric vehicle batteries are built — and what happens to them when they wear out? In this video from The How Factory, we take you inside modern battery production and recycling systems to reveal how EV battery packs are manufactured, tested, and recovered for valuable materials.

Watch how battery cells are assembled, welded, cooled, and packed into modules before becoming full-size battery packs for electric cars. You’ll see how automated machines handle precision work, how safety systems prevent overheating, and how quality control ensures batteries can deliver power for years.

Then we dive into battery recycling — showing how used battery packs are safely discharged, dismantled, sorted, and processed to recover critical metals like lithium, nickel, cobalt, and copper. This process is essential for reducing waste, lowering costs, and building a more sustainable energy future.

If you enjoy industrial engineering, clean energy technology, and “how it’s made” style documentaries, this behind-the-scenes look at EV battery manufacturing and recycling is a must-watch.
