In the embodiment, the isolator 37 is disposed between the communication terminal 331 and the power controller 321 for blocking the power controller 321 The signal generated by the power button 35 interferes with the signal. In other words, the interference signal generated by the power controller 321 is isolated by the blocker 37 before the battery 21 is energized to prevent the interference signal generated by the power controller 321 from being mistaken when the battery is inserted. It is thought that there is a button press operation, thereby waking up the battery 21 by mistake.

In this embodiment, the isolator 37 includes two connecting

ends

371, 372 and a control end 373. The two connecting

ends

371, 372 are electrically connected to the communication terminal 331 and the power controller 321 respectively. The control terminal 373 is electrically connected to the operating voltage receiving terminal 333, and when the control terminal 373 receives an operating voltage through the operating voltage receiving terminal 333, the two connecting ends 371 of the isolator 37 And 372 are turned on, and the communication terminal 331 is electrically connected to the power controller 321 .

When the isolator 37 is in the on state, the signal transmitted between the two connection ends 371, 372 is delayed and distorted, that is, the transmission between the power controller 321 and the battery assembly 20 The communication signal passes through the isolator 37 without delay and distortion.

In one of the embodiments, the isolator 37 includes a plurality of MOS tubes. The MOS transistor can be an NMOS transistor or a PMOS transistor. The plurality of MOS tubes may be connected in series.

Referring to FIG. 8, specifically in the illustrated embodiment, the isolator 37 includes two NMOS transistors Q9 and Q10, which are connected in reverse series. Each NMOS tube has a parasitic two Tube.

Direct communication between the battery pack 20 and the power controller 321 is isolated by the isolator 37.

In other embodiments, the isolator 37 can also include other electronic switches, such as diodes, solid state relays, and the like.

The mobile platform 30 of the present invention is multiplexed with the communication line by using a power switch bus, and the line can be used as a power button switch detection when not communicating, which can save the connector terminal. However, when the battery is inserted, since the IO pin of the mobile platform 30 is in an unstable state at the initial stage of power-on, it is possible to mistake the insertion of the battery as if the power button is pressed, and thus the center board may be accidentally triggered. The battery assembly 20 is activated after being electrically powered. By introducing an isolator 37, the present invention can effectively avoid the occurrence of the above-mentioned false triggering operation.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
