An EV will require X amount of power to travel Y miles. A battery has to deliver that amount of power. That same amount of power must be put in to the battery to be stored for use. The issue is the rate at which the battery can absorb the power to store. It takes time. Also is the amount of power available to store. No matter how you spin it those numbers don’t change. The goal is to quickly cram enough power into a battery without it exploding.
“The goal is to quickly cram enough power into a battery without it exploding.”
My solution is to have replaceable batteries like you have with battery powered tools. The “filling stations” would just replace your battery.
Well. No.
You need to put in100% power to store 92-85% of that power. Then you get out 90 to 85% of the power you stored. Net loss of 15-20% in the go-get-get out power. Rest is chemical and heat losses.
It’s these conversion losses they are trying to reduce.
