Instead of you charge your scooter, you drive to a battery swap station and exchange your empty battery for a full one. see [1].&lt;p&gt;But some companies are also investigating battery swap stations for cars.  So, you might not be able to swap a short-range battery with a long-range battery yourself, but I imagine that would be possible with those battery swap stations.  See [2].  Battery swap stations means that you have full range again for the same time it takes to fill a car with gas.  But obviously, you need to have enough of those stations to make it usable.  And if every car brand is gonna create its own mechanism for battery swapping, then that would probably only be interesting in city areas where it&amp;#x27;s worthwhile for the manufacturer to run those stations.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.electrive.com&amp;#x2F;2022&amp;#x2F;01&amp;#x2F;18&amp;#x2F;battery-swapping-stations-to-overtake-petrol-pumps-for-taiwan&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.electrive.com&amp;#x2F;2022&amp;#x2F;01&amp;#x2F;18&amp;#x2F;battery-swapping-statio...&lt;/a&gt;
