When designing the charger, part or all of the functional modules in the charger can be designed as replaceable modules; of course, the functional module with the replaceable or easily maintained portion can be predefined as the preset module according to whether the circuit module in the charger is the replaceable or easily maintained functional module.

Specifically, the operation parameter includes a node voltage at a detection node corresponding to the functional module, a node current at the detection node, an operating temperature of the charger, or communication data of the functional module.

For example, whether a switch module of the charger is in an abnormal state may be detected by detecting whether a voltage at a detection node in a switch detection circuit of the switch module is a preset voltage; judging whether the node voltage is a preset voltage or not, wherein the preset voltage is used for determining whether the output switch circuit is normal or not; if the node voltage is not the preset voltage, for example, is less than or greater than the preset voltage, it is determined that the switch module is in an abnormal state.

For example, whether the fan module of the charger is in an abnormal state or not may be detected by detecting a node voltage corresponding to a pin of a first interface terminal of the fan module, where the pin of the first interface terminal is a detection node; judging whether the node voltage is a high level, wherein the high level is a level corresponding to the normal work of the fan module; and if the node voltage is not at a high level, for example, if the node voltage is at a low level, determining that the fan module is in an abnormal state.

For example, whether the auxiliary source module, the temperature module and the rectifier module of the charger are in an abnormal state is detected, and whether the auxiliary source module, the temperature module and the rectifier module are in an abnormal state is judged by respectively detecting node voltages at detection nodes corresponding to the auxiliary source module, the temperature module and the rectifier module through the ADC detection module. Specifically, the node voltages of the auxiliary source module, the temperature module and the rectification module can be correspondingly detected through the auxiliary source detection circuit, the temperature detection circuit and the rectification detection circuit respectively.

In the above embodiment, the node voltage of each functional module is used to determine whether the functional module is in an abnormal state, and similarly, the node current may also be used to determine. Of course, other operation parameters may also be used for the determination, for example, whether the temperature module and the fan module are in the abnormal state is determined by the operating temperature of the charger, or whether the communication function of the rectifier module is in the abnormal state is determined by the communication data of the functional module.

And S102, if the functional module is in an abnormal state, informing the functional module in the abnormal state to a user.

For example, according to the preset correspondence between the functional modules and the notification manners in table 1, it can be determined that the rectifier module in the abnormal state corresponds to the notification manner 1, and the fan module in the abnormal state corresponds to the notification manner 2. Then, according to the correspondence between the lighting manner and the notification manner in table 2, the lighting manner corresponding to the notification manner 1 and the notification manner 3 can be determined. According to the determined lighting mode, the rectifying module and the fan module in abnormal states can be informed to the user through the four LED lamps in fig. 4.

Therefore, when the user charges the battery by using the charger, the user can know that the modules of the charger are abnormal, and maintain or replace the abnormal functional modules. Compared with the existing charger, the charger can only be replaced or a professional can only be found for maintenance when the charger is abnormal, the charging detection method can improve the maintenance efficiency of a user, saves the time and money cost of the user, avoids resource waste and further improves the experience of the user.

In order to quickly locate anomalies in the log information.

In addition, after the acquiring log information generated when the functional module is in an abnormal state and saving the log information, the method further includes: and closing a corresponding circuit for charging the battery by the charger to suspend charging the battery. For example, the rectifying module or the switching module is turned off to suspend charging the battery, because the abnormal phenomenon corresponding to the log information may be a relatively serious abnormal phenomenon, and the charger is turned off to charge the battery to suspend charging the battery, thereby improving charging safety and service life of the battery and the charger.

According to the charging detection method, when the charger is used for charging the battery, the abnormity of the functional module which is easy to maintain or replaceable can be detected, and the functional module is informed to a user, so that the user can complete the maintenance of the charger by replacing the related module.
