Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
In an embodiment of the invention, a kind of charging system is provided, including charging port, half straightening charging circuit and more
A battery core；Wherein, multiple battery core series connection, the input terminal of half straightening charging circuit connect charging port, the output of half straightening charging circuit
One battery core of end connection.That is, the output end of half straightening charging circuit connects any battery core.It should be noted that " multiple "
Meaning is two or more.
In embodiments of the present invention, charging system is designed as more battery core series connection, compared to monocell charging system, in the two
In the case where reaching Same Efficieney, in the concatenated design of more battery cores, the charging current that each battery core corresponds to access is respectively less than
Charging current in monocell charging system.As it can be seen that the present embodiment in order to meet quick charge speed can reach it is high-power, and it is same
When will not cause greatly very much because of charging current again fuselage heating it is too fast, thus take into account electronic equipment charging rate and temperature rise experience.
In addition, efficient half pressure charging circuit has been used cooperatively, compared to using straight in the charging system of the present embodiment
Charging circuit is pressed, the voltage of charging port can be made to double, the charging current on corresponding charging port reduces half.As it can be seen that
The present embodiment is on the basis of reduction battery core corresponds to the charging current on access, so that the charging current on charging port halves,
The charging current on charging port is further decreased, to be suitable for the conveyance capacity of traditional charging port and data line, in turn
Ensure the feasibility and versatility of the charging system in the present embodiment.
In a kind of design scheme of monocell, the battery of 2900mAh can be carried, and use the charging of 40w (5V/8A)
Device, in charging, the charging current of 8A is may be implemented in maximum, continues 5min or so, and charging is finally completed in 1h.The program is adopted
The mode filled with low-pressure direct, the passage current from charging port to battery battery core are up to 8A, and corresponding access heat power consumption is I2*
R (64*R), wherein can be according to formula: Ploss=I2* R, obtains heat power consumption, and Ploss indicates that heat power consumption, I indicate electric current, R table
Show the impedance of each component of access.Therefore, in the design process, need from wire rod, port, device flexible printed circuit board
(Flexible Printed Circuit, abbreviation FPC), battery protecting plate etc. do stringent impedance control in all-pass road and are filled with reducing
The heat power consumption of electric pathway, to need to pay higher design cost, and access generates when being ultimately limited by temperature rise and high current
Symbol high voltage, the charging current of 8A can only be realized when electricity is lower, continue the 5min time, need reduces electric current later fills
Electricity.Further, when battery capacity reaches 3500mAh~4000mAh, either in such a way that low-pressure direct fills or other
Efficient decompression scheme needs to design into battery current and reaches 6A or more to improve charging rate, can all exist and need to improve
Designed tide level path resistance needs to drop the problem of electric current sacrifices charger performance with complete machine temperature rise is limited to.As it can be seen that the party
Case major drawbacks are: the charging current into battery is excessive, causes the heat power consumption inside complete machine excessive, if necessary to control complete machine temperature
It rises, then needs to reduce the impedance R of each component of access, need to increase more cost in corresponding design, for example need to select support more
The voltameter integrated circuit (Integrated Circuit, abbreviation IC) of small sampling resistor, using bigger FPC of copper thickness etc..

It charges to improve charge power.It is such as connected using the battery core of two section 1800mAh, charging current is designed to 4A, corresponding to fill
Electric multiplying power can achieve 2.2c, and the access maximum current from charging port to battery core only has 4A, and corresponding access heat power consumption is
I2* the low-pressure direct of R (16*R), passage portion heat power consumption and traditional 20w or so fill scheme access heat power consumption and are on close level, and are not required to
Additionally to increase cost reduces the impedance of access, and corresponding charge power has been increased to 40w (10v/4A).The program can be more preferable
Performance charger performance, continue Maximum Power Output electron equipment fast charge in constant-current phase, and heat power consumption controls and more holds
Easily realize.But the program needs just to be able to achieve 40w using the charging port that can cross 4A electric current and data line wire rod of customization fast
It fills, the compatibility of charging cable is restricted, and cost is not up to optimal.
As it can be seen that compared with the design scheme of above-mentioned double cell, the heat power consumption of the charge circuit in the present embodiment and high straightening
The heat power consumption for filling charge circuit in scheme is suitable.It, can will be on charging port and on the basis of reaching 4A electric current on access
