The invention provides a dynamic battery pack switching and continuous power supply control method. The control method comprises the following steps: firstly, monitoring access and exit of a second battery pack in real time; performing pairing connection, searching a high-voltage battery pack, dynamically switching a strategy, and finally performing pull-out detection on a second battery pack; when the second battery pack is connected to the system, the first battery and the second battery pack are combined together after being balanced. And the equipment capacity is expanded, so that the external endurance time of the equipment is prolonged. The first battery pack and the second battery pack are combined together to be equivalent to a large battery and are charged and discharged together, so that the real-time balance of the voltage of the battery packs is ensured. The maximum effect of the battery pack parallel control algorithm is that the safety of the second battery pack is ensured, and the charge-discha
