In order to better understand the function of charging and discharging at the same time, the working process is described, the first MOS tube is replaced by Q1, the second MOS tube is replaced by Q2 and … …, the fifth MOS tube is replaced by Q5, and the sixth MOS tube is replaced by Q6, specifically as follows:
when the TYPE C-C1 interface is connected with a 65W charger to charge the charger (namely, the operation of a first point), the TYPE C-C2 interface is connected with a powered device such as a mobile phone or a notebook, after the U3 wakes up through a 6 th pin and a 7 th pin, PDO identified by the TYPE C-C1 is directly broadcasted on the TYPE C-C2 once (5V-3A/9V-3A/12V-3A/15V-3A/20V-3.25A) and then waits for the TYPE C-C2 interface device to respond to the requirement;
in the first case, the device response requirement is TYPEC-C1 maximum power 65W; for example, when the device responds that 20V-3.25A PDO is needed, U3 will control U5 (i.e. SC8886 described above) through 13 th and 16 th pins, 32 nd pins of U3 control Q1 and Q2 to close the power charging to the charger itself, and at the same time, U3 outputs low level through 26 th pin to open Q5 and Q6, and directly transmits 20V-3.25A power of the TYPEC-C1 interface charger to the TYPEC-C2 interface for power transmission, so as to achieve the goal of fast charging;
in the second case, the device response requirement is not 65W of maximum power of TYPE C-C1; for example, when the device responds that 20V-2.25A PDO is needed, U3 controls U5 through 13 th pin and 16 th pin, the charging power of the charger baby is controlled in the range of 20W (65W-45W), meanwhile, U3 outputs low level through 26 th pin to open Q5 and Q6, and meanwhile, the remaining 45W (20V-2.25A) power of the TYPE C1 interface charger is directly transmitted to the TYPE C2 interface, so that the power redistribution is realized, and the aim of quick charging is fulfilled.
Otherwise, the same theory is adopted
When the TYPE C-C2 interface is connected with a 65W charger to charge the charger (namely, the operation of a first point), the TYPE C-C1 interface is connected with a powered device such as a mobile phone or a notebook, after the U3 is awakened by the 3 rd pin and the 4 th pin, PDO identified by the TYPE C-C2 is directly broadcasted on the TYPE C-C1 once (5V-3A/9V-3A/12V-3A/15V-3A/20V-3.25A) and then waits for the TYPE C-C1 interface device to respond to the requirement;

in the second case, the device response requirement is not 65W of the maximum power of the TYPEC-C1, for example, when the device response only needs 20V-2.25A PDO, U3 controls U5 through 13 th and 16 th pins, the charging power of the charger self is controlled in the range of 20W (65W-45W), meanwhile, U3 outputs low level through 26 th pin to open Q5 and Q6, and meanwhile, the power of the remaining 45W (20V-2.25A) of the TYPEC-C2 interface charger is directly transmitted to the TYPEC-C1 interface, so that the aim of quick charging is achieved.
Of course, the function of separate charging and discharging can also be realized.
1, TYPEC-C1/C2 charging alone
When a typec-C1 interface is connected to a charger, two pins CC1 and CC2 of a seat wake U3 through pins 3 and 4 of U3, the U3 is identified to be the charger after being waken up, PDO connected to the charger is analyzed, if the PDO is 65W (5V-3A/9V-3A/12V-3A/15V-3A/20V-3.25A), U3 will default to select the highest gear 20V-3.25A, and return information to the charger, after confirming that the charger normally outputs 20V through a 30 th pin detection R61/R62 resistor 10K:1K partial pressure 1.8V of U3, the U3 outputs low level to open two MOS of Q1 and Q2 through a 32 rd pin of U3, and I2C communication is performed through a 13 pin and a 16 pin of U3 and U5, so that the U5 is in a charging state, and the maximum charging power is controlled within 65W of the PDO;
similarly, when the typec-C2 interface is connected to the charger, the type of the working process is not repeated here;
2, TYPEC-C1/C2 discharge alone
When a typec-C2 interface is connected with a powered device, two PIN PINs of CC1 and CC2 of a seat wake U3 through PINs 6 and 7 of U3, when the U3 recognizes that the connected device is the powered device, the maximum output power PDO65W (5V-3A/9V-3A/12V-3A/15V-3A/20V-3.25A) of the charger is sent, the powered device receives the charged discharge PDO, selects one of the files, such as 9V-3A, and sends the information back to PINs 6 and 7 of U3 through CC1 and CC2, after the U3 receives the information, the U1 is controlled to output power of 9V-3A through PINs 8/9, and two MOS devices Q3 and Q4 are opened through PINs 31 of U3 to discharge outwards;
similarly, when the typec-C1 interface accesses the powered device, the operation process type is not described herein.
According to the scheme, the PD chip, the quick charge chip, the first control circuit, the second control circuit and the transparent transmission control circuit are arranged; when the battery is charged and discharged simultaneously, the received PDO is utilized to confirm the maximum power of one charger and then distribute the maximum power, and then the power is distributed to the other TYPE C interface to be output outwards, so that the function of quick charging and discharging with the maximum power is realized, the defects of resource waste, poor user experience, battery charging through TYPE, external discharging by using the battery, and low cycle times and efficiency affecting the service life of the battery in the prior art are overcome.
Finally, it should be noted that the above description is only specific embodiments of the present utility model, but the scope of the present utility model is not limited thereto, and any changes or substitutions that may be easily contemplated by those skilled in the art within the technical scope of the present utility model should be included in the scope of the present utility model.
