[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] After the host starts self-cleaning, the host controls the base station through the signal line to start the drying function: there are two specific situations; Case 1: The DC load is electrically connected to the base station battery through the fifth switch S5, the heating load is electrically connected to the base station battery through the sixth switch S6, and both the fan load and the heating load are powered and controlled by the base station battery; The second situation: the DC load is electrically connected to the base station battery through the fifth switch S5, the heating load is electrically connected to the adapter through the sixth switch S6, the fan load is powered and controlled by the base station battery; the heating load is powered and controlled by the adapter.

[0019] Specifically, the base station battery and the host battery are both provided with a power detection module, which is electrically connected to the control board of the host. The power detection module is used to monitor the power of the base station battery and the host battery in real time, and the power detection module transmits a signal to the control board of the host.

[0020] The working principle of the power control system for the floor scrubber is that when the host is installed (placed) on the base station, the adapter charges the host battery first, and after the host battery is fully charged, the base station battery is charged.

[0021] After the user takes the host and runs it, he / she monitors the battery power of the base station in real time. If the base station battery is not fully charged, he / she will charge the base station battery. The base station battery and the host battery are both removable and interchangeable. When the dead host battery is swapped with the base station battery, it can be charged in time.

[0022] During self-cleaning, the host battery is used to power the host load first. The priority of powering the host load is host battery>adapter>base station battery.

[0023] When the host battery power is insufficient, use the host battery and adapter to power the host load. If it is still not enough, use the base station battery to power the host load. If it is still not enough, use the base station battery and adapter together. If it is still not enough, use the base station battery + host battery together. If it is still not enough, use the base station battery + host battery + adapter to power the host together.

(At this time, there is a voltage balancing process, but it will eventually become ③) ① When the host battery voltage is greater than the base station battery voltage, the host battery supplies power to the host load and charges the base station battery at the same time; ② When the host battery voltage is less than the base station battery voltage, the base station battery supplies power to the host load and charges the host battery at the same time; ③When the host battery voltage is equal to the base station battery voltage, the base station battery + host battery supplies power to the host load; The first switch S1 is connected to the contact 2, the second switch S2 is closed, the third switch S3 is closed, and the fourth switch S4 is closed.
