The invention discloses a battery module and an intelligent charging method thereof. The battery module is electrically connected with the load system; the battery module comprises a battery, a detection unit and a processing unit, wherein the detection unit is connected with the processing unit and the battery; when the battery module is electrically connected with the charger, the detection unit detects the voltage of the battery and the current flowing through the load system; when the battery module is electrically connected with the charger, the processing unit controls the magnitude of the output current and the output voltage of the charger through the channel, and judges whether the battery is in a constant-current charging mode or a constant-voltage charging mode according to the magnitude of the voltage of the battery. When the processing unit judges that the battery is in the constant-current charging mode, the magnitude of the output current of the charger is dynamically increased based on a default rule; and when the processing unit judges that the battery is in the constant voltage charging mode, the output voltage of the charger is dynamically increased based on a default rule. Therefore, the problem that the battery module is electrically connected with the load system, so that the battery cannot be fully charged effectively can be solved.
Description
technical field [0001] The present application relates to the technical field of charging, and in particular, to a battery module and an intelligent charging method thereof. Background technique [0002] see figure 1 , which is a system architecture diagram of charging by a charger when a traditional battery module is connected to a load system. Wherein, Vchg is the voltage of the charger 110 , Vbat is the voltage of the battery module 120 , Vload is the voltage of the load system 130 , I_chg is the total current output by the charger 110 , and I_bat is the current shunt flowing through the battery module 120 size, I_load is the size of the current shunt flowing through the load system 130 , which satisfies I_chg=I_bat+I_load. [0003] like figure 1 As shown, since there is no way between the battery module 120 and the charger 110 to know that the battery module 120 is charging under the connection with the load system 130 , when the battery module 120 is charged under th...
