Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Because portable battery is mostly the customization product, for the convenience of battery charging, often design into the general type interface that charges, but the adapter that the interface is general that charges often charging power is different, because adapter power is different, so need set up two gears that fill soon and slowly to the battery and adapt to different adapters.
In a possible scenario, the battery system also needs a key to display the amount of power, and if a charging gear (fast-slave, slow-charge) switching function needs to be added, one is to use a professional charging chip to cooperate with a dedicated charging adapter to realize adaptive fast-charge and slow-charge functions in the battery device, but the cost of the chip and the adapter is high, which increases the design cost of the product. Another way is to add a button inside the battery device to switch the charging mode specially, but this will increase the device volume, increase the device weight, and affect the product beauty.
In order to overcome the above problems, an embodiment of the present application provides a charging device, please refer to fig. 1, where fig. 1 is one of connection schematic diagrams of the charging device provided in the embodiment of the present application.

As shown in fig. 1, when the self-resuming switch module 30 is closed, the monitoring end of the switching module 20 is grounded and is in a low level state, and when the self-resuming switch module 30 is resumed to be disconnected, the monitoring end of the switching module 20 is equivalently connected to the first power VCC and is in a high level state, and the number of hopping times can be determined by monitoring the number of level changes of the monitoring end of the switching module 20. It should be noted that the number of transitions is the number of transitions from the normally open state to the closed state of the self-recovery switch module 30, that is, the number of transitions from the high level state to the low level state of the monitoring terminal of the switching module 20.
The preset gears in the embodiment of the application can comprise a plurality of gears, are not limited to fast charging or slow charging, and the types of the control signals are variable; when the self-recovery switch module 30 does not jump, the control signal is a default signal (e.g., a low level signal), and the execution module 10 keeps the default gear (e.g., slow charging) for charging.
The execution module 10 is configured to charge the battery B1 according to the target charging gear when receiving the control signal.

In the case where the number of the first type sub-signals is less than or equal to N, all of the variable units 101 may be controlled to be in the truncated state; alternatively, there is and only one variable cell 101 in the on state; alternatively, two or more variable units 101 may be in a conducting state, and the current voltage of the monitoring gear pin may change accordingly, so as to instruct execution module 10 to switch between more gears.
