Why does fast charging degrade electric car batteries?

Fast charging can make electric car batteries tired faster, just like when you run around a lot without resting.

Batteries in electric cars are like big energy storage tanks, and they use tiny parts called cells to hold the power. When you charge your car quickly, it's like pouring a big glass of juice into a little cup, too fast, and the cup can get full too quickly, making it feel strained.

When you plug in your car for a quick charge, it sends a lot of energy into the battery in a short time. This is like giving the tiny cells inside a big hug all at once, instead of letting them rest and recover slowly.

Every time you do this, fast charging, it can cause little wear and tear on the battery cells, just like how your shoes might get worn out if you run too much without taking breaks. Over many charges, this wear and tear adds up, making the battery less strong over time.

So even though fast charging is super cool and saves time, using it a lot can make the car’s battery feel tired sooner, kind of like how your body feels after playing all day!
