They probably have some ways of battery swapping, by having supplies ships replenishing with a new batch of batteries. There is no need to recharge those lithium batteries.
1) Many new ships will be powered by ammonia or hydrogen, most will be driving electric motors. So there's a power source available for recharging batteries for ships carrying modules that require a lot of power.
2) Many of these types of ships will be relatively small, capable of going very far inland, so they can be built and equipped in more inland ports like Wuhan.
