Fig. 1 is a schematic diagram of a battery circuit in the related art. As shown in fig. 1, in the related art, taking a lithium battery as an example, the battery circuit includes a battery cell 101 and a battery cell protection circuit 102, and the battery cell protection circuit 102 is connected to the negative electrode of the battery cell 101. In the charging process for lithium batteries, four charging states may be generally included, and in particular, a trickle charging phase, a constant current charging phase, a constant voltage charging phase, and a termination phase may be included. The voltage at the positive electrode of the battery cell 101 and the two ends of the battery cell protection circuit 102 can be detected in the trickle stage, the constant current charging stage is switched to after the voltage rises to a certain threshold value, the lithium battery can be charged with constant current in the constant current charging stage, the voltage at the positive electrode of the battery cell 101 and the two ends of the battery cell protection circuit 102 is continuously detected, and the constant voltage charging stage is switched to after the voltage rises to a certain threshold value, and finally the charging is terminated. The constant-current charging stage is the stage with the highest efficiency in the charging process, so that the prolonging of the duration of the constant-current charging stage is of great significance for improving the charging efficiency of the lithium battery.
In the related art, since the detected voltages are voltages at the positive electrode of the battery cell 101 and two ends of the battery cell protection circuit 102, it can be understood that the battery cell protection circuit 102 includes a resistor composed of a primary protection device, a secondary protection device and line impedance, so that a voltage difference between the voltages at the positive electrode of the battery cell 101 and the two ends of the battery cell protection circuit 102 and the voltage of the battery cell 101, that is, the voltages at the positive electrode of the battery cell 101 and the two ends of the battery cell protection circuit 102 are higher than the actual battery cell voltage of the battery cell 101, the duration of the constant-current charging stage is shortened, the constant-voltage charging duration is lengthened, and the charging efficiency is affected.
The present disclosure thus provides a battery circuit as shown in fig. 2, which may include a battery cell 1 and a charge-discharge loop 2, which charge-discharge loop 2 may include a positive terminal 21, a negative terminal 22, and a circuit protection device 23. The circuit protection device 23 may be connected to the negative electrode of the battery cell 1, the positive electrode terminal 21 is conducted to the positive electrode of the battery cell 1, the negative electrode terminal 22 may be conducted to the negative electrode of the battery cell 1 through the circuit protection device 2, the positive electrode terminal 21 and the negative electrode terminal 22 may further output the electric energy stored in the battery cell 1, or the external charging terminal may charge the battery cell 1 through the positive electrode terminal 21 and the negative electrode terminal 22. The circuit protection device 23 may include a primary protection device and a secondary protection device.
Further, the battery circuit may further include a detection circuit 3 and a battery management chip 4, and the detection circuit 3 may include a first output terminal 31 and a second output terminal 32, where the first output terminal 31 is connected to the positive electrode of the battery cell 1, and the second output terminal 32 is connected to the negative electrode of the battery cell via the battery management chip 4. The first output 31 can thus output the positive voltage of the cell 1, while the output object of the second output 32, which can include the negative voltage of the cell 1 and the voltage of the negative terminal 22 of the charge-discharge circuit 2, can be switched by the battery management chip 4.
Based on this, the first output end outputs the positive voltage of the battery cell 1, the second output end 32 outputs the negative voltage of the battery cell 1, so that the voltage of the battery cell 1 can be obtained, and the battery circuit adjusts the charging state of the battery according to the voltage of the battery cell, wherein the charging state can include a constant current charging state and a constant voltage charging state, and the voltage detected by the detection loop 3 is the voltage of the battery cell 1, so that the situation of pressure difference caused by the existence of a battery cell protection circuit in the related art can be avoided, the holding time of the constant current charging state is prolonged, the charging efficiency is improved, and the charging time can be shortened under the condition of charging batteries with the same capacity; in addition, when the second output terminal 32 outputs the voltage of the negative terminal of the charge-discharge circuit 2, the voltage of the series circuit formed by the battery cell 1 and the circuit protection device 23 can be obtained, so that the protection state of the circuit protection device 23 can be adjusted according to the detected voltage, and the battery circuit can be protected by the circuit protection device 23.
Specifically, as still shown in fig. 2, the battery management chip 4 may include a logic switch 41, where the logic switch 41 may be connected to the negative electrode of the battery cell 1 and the second output terminal 32, and when the logic switch 41 is in the closed state, the second output terminal 32 outputs the negative electrode voltage of the battery cell 1, and when the logic switch 41 is in the open state, the second output terminal 32 may output the voltage of the negative electrode terminal on the charge-discharge circuit 2 through the battery management chip.
In the present embodiment, it may be a switching instruction when the battery management chip 4 determines that the charge-discharge state of the charge-discharge circuit 2 is abnormal, which switching instruction may be used to instruct the logic switch 41 to switch to the off state. When it is determined that the charge and discharge state of the charge and discharge circuit 2 is normal, the battery management chip 4 may also generate a switching instruction indicating that the logic switch 41 is switched to the closed state, so that on the one hand, the charge efficiency may be improved when the circuit is normal, and the battery may be protected when the circuit is abnormal.
For example, as shown in fig. 3, taking a charging current of 4.8 amperes and a cut-off current of 200mAd as an example, when the related technical scheme shown in fig. 1 is adopted under the condition that the capacities of the electric cores are the same, the constant current charging duration is 28 minutes, the total charging duration is 79 minutes, and the electric core adopting the technical scheme of the present disclosure can extend to 28 minutes in the constant current charging stage, and the total charging duration is 78 minutes. Therefore, by adopting the technical scheme disclosed by the invention, the duration of the constant current charging stage can be prolonged, the total charging duration is shortened, and the charging efficiency is improved.
The abnormal conditions such as charge overvoltage, discharge undervoltage, charge overcurrent, discharge overcurrent, short circuit and the like of the battery can be determined as abnormal charge and discharge states, so that the logic switch 41 is switched to the off state, and the risk of battery damage caused by the increased detection loop 2 can be reduced. Specifically, when the charging voltage exceeds the platform voltage of the battery cell 1, the battery is in an abnormal state of charging overvoltage, when the discharging voltage exceeds the safety voltage of the battery cell 1, the battery is in an abnormal state of discharging undervoltage, when the charging current exceeds the charging protection current, the battery is in an abnormal state of charging overcurrent, and when the charging current exceeds the discharging protection current, the battery is in an abnormal state of discharging overcurrent.
In the above embodiments, as shown in fig. 4, the detection circuit 3 may further include a resistor 33, where the resistor 3 connects the positive electrode of the cell 1 and the first output terminal 31. In this way, since the first resistor 33 is connected in series to the first output terminal 31, when the battery is assembled by the connector, a short circuit can be avoided in the case of erroneous connection between the first output terminal 31 and the negative electrode terminal 22 or in the case of conduction of the first output terminal 31 to the negative electrode terminal 22 by other conductive structures, so that the battery connector or the detection circuit 2 is prevented from being burnt. The resistance of the resistor 33 may be smaller to reduce the error between the voltage detected by the detection circuit 2 and the actual voltage of the battery cell 1.
In the above embodiments, the battery circuit may further include an inductor 5, and the inductor 5, the logic switch 41 and the second output terminal 32 are connected in series. The current flowing through the detection loop 3 is hindered by the inductance 5. In this way, when the logic switch 41 is in the closed state, the current input through the negative terminal 22 will flow to the circuit protection device 23, but not to the detection circuit 3, due to the inductor 5 on the detection circuit 4, so that the detection circuit 3 can perform the voltage detection function, and the charge-discharge circuit 2 can perform the charge-discharge function. The inductor 5 may be independent of the battery management chip 4, and as shown in fig. 4, the inductor 5 is connected to the output pin and the second output terminal 32 of the battery management chip 3, or the inductor 5 may be an inductor included in the battery management chip 4, which is not limited in the present disclosure.
Based on the battery circuit described in the above embodiments, the present disclosure also provides an electronic device, which may include the battery circuit described in any one of the above embodiments. The electronic device may include a mobile phone terminal or tablet terminal, etc., and the present disclosure is not limited.
The present disclosure also provides a charging method applied to the battery circuit according to any one of the above embodiments, as shown in fig. 5, where the charging method may include:
in step 501, a charge-discharge state for a battery is determined.
In the present embodiment, the charge-discharge state may include a charge-discharge normal state and a charge-discharge abnormal state. The charge-discharge abnormal state may include at least one of charge overvoltage, charge undervoltage, charge overcurrent, discharge overcurrent, and short circuit.
In step 502, when the charge/discharge state is determined, the output object of the second output terminal is switched, where the output object includes the negative voltage of the battery cell and the voltage of the negative terminal of the charge/discharge circuit.
In this embodiment, when the charge and discharge state is normal, the output object of the second output end is the negative voltage of the battery cell, so that the charging efficiency is improved in the charging process; when the charge and discharge state is abnormal, the output object of the second output end is the voltage of the negative electrode end of the charge and discharge loop, so that the battery circuit is protected by the circuit protection device.
Specifically, the switching state of the logic switch included in the battery management chip may be switched according to the charge/discharge state, so as to switch the output object of the second output terminal. When the logic switch is in a closed state, the output object of the second output end is the negative voltage of the battery cell; when the logic switch is in an off state, the output object of the second output end is the voltage of the negative end of the charge-discharge loop.
