With so much emphasis put on the usability of the electric vehicle around the exterior, including a live update on how many miles are left under the current battery charge, the likelihood is that you will never completely run out of charge.
Every EV app is designed to support your journey not matter how long or short it is, providing the safest charge points at which you can stop to refuel without ever coming close to hitting the red bar on the charge block.
If you appear to be running low on charge quicker than you anticipated, drive more economically – turn down the air condition or heating, accelerate as gently as you can, and try to avoid driving hard up hills.
