Specifically, the charging state of the Bluetooth headset detected by the charging circuit 101 includes the following two types:

First, when the Bluetooth headset is fully charged and in the state of complete charging, in order to protect the Bluetooth headset and reduce power consumption, the control circuit controls the switch circuit to disconnect after receiving the signal to complete the charging, so that the charging circuit form a circuit breaker.

Second, when the Bluetooth headset is not fully charged and in the state of incomplete charging, in order to further use the Bluetooth headset, the Bluetooth headset needs to be charged, and the control circuit controls the switch circuit to close after receiving the signal of incomplete charging. So that the charging circuit forms a path, and then the Bluetooth headset is charged.

It should be noted that when the Bluetooth headset is fully charged or not fully charged, it is still charging and not charging. Therefore, the charging circuit also detects whether the Bluetooth headset is charging and outputs the detected result to the control circuit. , the control circuit outputs corresponding commands to control the switch circuit to perform corresponding actions.

Optionally, the charging circuit detects the charging current and/or the battery voltage of the Bluetooth headset as a basis for judging the charging state of the Bluetooth headset.

For example, the charging circuit detects the current in the Bluetooth headset. If the detected current is the charging current, it means that the Bluetooth headset is charging; if the detected current is always less than the charging current, it means that the Bluetooth headset is not charging and is in uncharged state.

For example, the charging circuit detects the size of the battery voltage in the detected Bluetooth headset. If the detected battery voltage is the full voltage, it means that the Bluetooth headset has been charged and the Bluetooth headset is fully charged; if the detected battery voltage is less than fully charged voltage, it means that the Bluetooth headset is not fully charged and is in an incomplete charging state.

Therefore, information such as whether the Bluetooth headset is being charged and whether it is fully charged can be obtained by measuring the current and voltage of the charging circuit.
