Description
Technical Field
[0001] The utility model relates to a charger, in particular to an intelligent mobile charging shunt. Background Art
[0002] Currently, there are two types of batteries available on the market for users to choose from: primary batteries and storage batteries. Storage batteries need to be charged using a matching charger, but in the prior art, chargers are usually only designed with one output connector for charging, so a charger can only charge one storage battery at a time, resulting in low charging efficiency.
[0003] Some prior arts disclose a charger with two output connectors, but the output currents of the two output connectors cannot be controlled. Therefore, one of the output connectors may have fully charged the battery and be in an idle state, while the other battery is still being charged, which results in a prolonged charging time and low charging efficiency.

[0007] Through the above technical solution, by setting up no less than two output connectors for charging the batteries, two batteries can be charged at the same time, and the number of chargers can be reduced while improving the charging efficiency, thereby saving space and cost; in addition, the electronic control module can obtain the remaining power of the two rechargeable batteries to adjust the charging speeds of the two output connectors, such as increasing the charging speed of the battery with lower remaining power and decreasing the charging speed of the battery with higher remaining power. After reasonably allocating the charging speeds of the two output connectors, the two batteries can be charged synchronously, avoiding the impact of charging efficiency due to one of the output connectors being idle.
[0008] Preferably, the electric control module comprises two groups of control units with the same structure, the two groups of control units are connected to the output ends of the two input connectors in sequence and in parallel.
[0009] Preferably, the two groups of control units each include a power tube and a chip, the drain of the power tube is respectively connected to the output connector and one end of the sampling resistor R, the other end of the sampling resistor R is connected to the SR interface of the chip, and the gate of the power tube is connected to the DRV interface of the chip; the source of the power tube in the two control units is connected to the positive electrode of the diode D, and the negative electrode of the diode D is connected to the input connector.
[0010] Through the above technical solution, through the setting of the chip, the charging status of each rechargeable battery can be obtained, and a control instruction can be issued after analysis and calculation, and then the output current of the two output connectors used to charge the battery can be controlled through the power tube, so as to adjust the charging speed of the two batteries. The chip monitors the charging status of the two batteries in real time and adjusts the output current of the corresponding output connector in real time, so that the two batteries can complete the charging work synchronously.

[0020] In a possible embodiment, as shown in the attached Figure 1 As shown, an intelligent mobile charging diverter includes a shell, an input connector and no less than two output connectors. In this specific embodiment, two output connectors are provided. An electric control module is provided in the shell. The electric control module is electrically connected to the input connector. The other end of the input connector is used to be connected to a power source. The electric control module is electrically connected to the output connectors respectively. The output connectors are used to be connected to a battery to be charged. The electric control module is used to distribute the current output by the input connector to the two output connectors; the two output connectors are respectively connected to the two batteries to be charged, so that the two batteries can be charged at the same time. While improving the charging efficiency, the number of chargers can be reduced, thereby saving space and cost; in addition, the electric control module can obtain the remaining power of the two rechargeable batteries to adjust the charging speed of the two output connectors, such as increasing the charging speed of the battery with a lower remaining power and decreasing the charging speed of the battery with a higher remaining power. After reasonably allocating the charging speeds of the two output connectors, the two batteries can be charged synchronously, avoiding the impact of one output connector being idle and affecting the charging efficiency.
[0021] The electric control module includes two groups of control units with the same structure. The two groups of control units are connected to the output ends of the two input connectors at one time, and the two groups of control units are connected in parallel. Both groups of control units include power tubes and chips. In this embodiment, LZW7809 chips are used. The power tubes and chips are integrated on the circuit board.
[0022] The two control units both include a power tube and a chip. The drain of the power tube is connected to the output connector and one end of the sampling resistor R, respectively. The other end of the sampling resistor R is connected to the SR interface of the chip. In this specific embodiment, the resistance of the sampling resistor R is 100Ω. The gate of the power tube is connected to the DRV interface of the chip. The source of the power tubes in the two control units is connected to the positive electrode of the diode D. The negative electrode of the diode D is connected to the input connector. The model of the diode D in this specific embodiment is SS210. The output current in each output connector can be fed back to the chip through the branch where the sampling resistor R is located. Then the chip can obtain the charging status of each rechargeable battery, and issue a control instruction after analysis and calculation, and then control the output current of the two output connectors used for charging the battery through the power tube, so as to adjust the charging speed of the two batteries. The chip monitors the charging status of the two batteries in real time and adjusts the output current of the corresponding output connector in real time, so that the two batteries can complete the charging work synchronously.
[0023] The VCC interfaces of the two chips are connected to capacitor C1, and the other end of each capacitor C1 is connected to the cathode of diode D. The VIN interface of the chip is connected to VCC_H, and the GND interface of the chip is connected to capacitor C2, and the other end of capacitor C2 is connected to the input end of VCC_H. The NC interface of the chip is connected to the input end of capacitor C2. Both capacitor C1 and capacitor C2 are 100nF.
[0024] Working principle: The user connects the two output connectors on the charger to the two batteries to be charged respectively, and connects the input connector on the charger to the external power supply. At this time, the two batteries can be charged separately. The current enters from the input connector and is transmitted to the two rechargeable batteries through the two output connectors. That is, the electronic control module in this charger can distribute the current output by the input connector to the two output connectors. The chip can obtain the charging status in the charging branch in real time, and control the current output size of the branch where the output connector is located by the power tube after analysis and calculation, to ensure that the two batteries are charged synchronously, and continuously monitor the entire charging process to facilitate adjustment of the charging current at any time, avoid a certain output connector being idle, and improve charging efficiency.
