Battery swaps can work for both cars and trucks. I am going to focus mostly on trucks.
This is the Chinese solution. According to this article in Electrive from, January 2026, CATL, the battery manufacturer behind this, there are 305 swap stations for trucks and 1020 for cars in operation. The numbers are expanding rapidly and are probably already a lot higher as I write this in March.
Battery swaps are established technology.
With this system, there is more latitude to charge at favourable times then with chargers which require drivers to wait while the truck charges. Of course, for this theoretical advantage to become real, there would need to be plenty of spare batteries. So, I am not sure how big an advantage this is in practice.
Organisationally, there is more complexity in this system. In China, there is a single provider of batteries, CATL. I am not sure how well the central provider model would work here in Australia. And having different providers with their own pools of batteries might not work so well either. Then again, I could imagine a single swap station operator maintaining different stacks of batteries for different truck companies.
Here is an article Australian truck companies improvising trucks with battery swaps for intercity freight. This works for relatively short routes like Sydney to Canberra. Below is a picture of batteries being inserted into a truck with a fork lift.
