Why are we not already able to “instant-charge” EVs, smartphones or other batteries?
In: Physics
Are you asking why it takes time to recharge a battery and can’t be done instantly?
If so, then think of a battery as a bucket with very thin sides. If you slowly add water to the bucket it will fill up and hold all the water. If you blast the water in as fast as possible you will damage the bucket because the sides will fail due to the force and it won’t hold any water.
The slower you add the safer it is.
