Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a charging method provided by an embodiment of the present invention, where the method may be applied to a charger, and as shown in the figure, the method includes:
s101, detecting the initial battery voltage of the rechargeable battery under the condition that the rechargeable battery is accessed.
When the rechargeable battery is connected, the initial battery voltage of the rechargeable battery is detected under the condition that the positive and negative electrodes of the rechargeable battery are correctly connected with the two output end electrodes of the charger, the correct connection of the positive and negative electrodes of the rechargeable battery and the two output end electrodes of the charger means that the positive electrode of the rechargeable battery is connected with the positive output end of the charger, and the negative electrode of the rechargeable battery is connected with the negative output end of the charger.
In a specific implementation, the initial battery voltage of the rechargeable battery may be detected by a voltage detection circuit, a part of circuits inside the charger may be as shown in fig. 2, before the rechargeable battery is connected, a charging loop is not formed between the charger and the rechargeable battery, the relay is in an off state, and the voltages at two output terminals of the charger, which are detected by the voltage detection circuit, are always equal to zero; when the rechargeable battery is connected, the charger and the rechargeable battery form a charging loop, the relay is not conducted, and the voltages at two output end poles of the charger detected by the voltage detection circuit are equal to the voltages at two ends of the rechargeable battery, namely the initial battery voltage of the rechargeable battery.
In a possible implementation manner, the initial battery voltages at two ends of the rechargeable battery can be directly detected when the rechargeable battery is connected, or the voltages of preset detection points in a voltage detection circuit can be detected when the rechargeable battery is connected, then the corresponding relationship between the voltages of the preset detection points and the voltage of the positive electrode output end is determined according to the specific connection relationship of the voltage detection circuit and the position relationship between the preset detection points and the positive electrode output end, and then the initial battery voltage of the rechargeable battery is obtained through conversion according to the corresponding relationship.
And S102, determining a target charging scheme and a target overcharge voltage according to the initial battery voltage.
The overcharge voltage refers to a maximum voltage that can be reached by charging the secondary battery without damaging the secondary battery.
According to the charging and discharging characteristics of the rechargeable battery, the voltage of the rechargeable battery is not fixed and fluctuates in a voltage interval, and the voltage fluctuation ranges corresponding to the rechargeable batteries with different specifications are different. The fluctuation range of the rechargeable battery is greater than or equal to a first voltage and less than or equal to a second voltage, the first voltage is the voltage of the rechargeable battery when the discharge voltage is stable, the second voltage is the voltage of the rechargeable battery when the rechargeable battery is fully charged and the voltage is stable, namely the first voltage and the second voltage are both the voltages after standing for a period of time.
As shown in fig. 3, fig. 3 is a schematic diagram of voltage variation of the rechargeable battery under different conditions, where the battery voltage corresponding to point B is the overcharge voltage, the battery voltage corresponding to point a is the first voltage, and the battery voltage corresponding to point C is the second voltage.
In a possible scenario, voltage fluctuation ranges corresponding to the rechargeable batteries with different specifications do not coincide with each other, a voltage interval can be divided according to the voltage fluctuation range of the rechargeable battery, and a corresponding relation between the voltage interval and the rated voltage and the overcharge voltage of the rechargeable battery is preset.
In another possible scenario, voltage fluctuation ranges corresponding to two adjacent specifications of rechargeable batteries overlap, a voltage interval can be divided according to the voltage fluctuation range of the rechargeable batteries, a corresponding relation between the voltage interval and the rated voltage of the rechargeable batteries can be preset, and then a corresponding relation between the voltage interval and the overcharging voltage is preset according to the corresponding relation between the rated voltage and the overcharging voltage of the rechargeable batteries. In this scenario, one voltage interval corresponds to two rated voltages, and in order to avoid charging the less rated rechargeable battery, the overcharge voltage of the less rated rechargeable battery of the two rated voltages may correspond to the voltage interval, where determining the target charging scheme and the target overcharge voltage according to the initial battery voltage includes: determining a voltage interval to which the initial battery voltage belongs, and determining a first rated voltage and a second rated voltage of the voltage interval, wherein the first rated voltage is smaller than the second rated voltage; and determining the overcharging voltage corresponding to the first rated voltage as a target overcharging voltage, and determining the charging scheme corresponding to the first rated voltage as a target charging scheme.
The following describes the schemes of the above two scenarios by way of example.
For example, the rechargeable battery may have three specifications, and the rated voltages are 2V, 4V and 6V, wherein the voltage fluctuation range of the rechargeable battery with the rated voltage of 2V is [1.5V, 2.2V ], the voltage fluctuation range of the rechargeable battery with the rated voltage of 4V is [3.2V, 4.8V ], the voltage fluctuation range of the rechargeable battery with the rated voltage of 6V is [5V, 7.2V ], that is, the voltage fluctuation ranges of the batteries with the three specifications do not overlap with each other, the voltage fluctuation ranges of the rechargeable batteries with the three specifications may be directly used as the voltage intervals, and the corresponding relationships between the preset voltage intervals and the rated voltages and the overcharging voltages may be as shown in table 1:
| voltage interval | Rated voltage | Overcharge voltage |
| [1.5V，2.2V] | 2V | Overcharge voltage of 2V battery |
| [3.2V，4.8V] | 4V | Overcharge voltage of 4V battery |
| [5V，7.2V] | 6V | Overcharge voltage of 6V battery |
TABLE 1
If the initial battery voltage of the accessed rechargeable battery is detected to be 3.5V, and the voltage interval to which the 3.5V belongs is [3.2V, 4.8V ], the rated voltage of the accessed rechargeable battery can be determined to be 2V according to the corresponding relation shown in the table 1, the overcharging voltage is the overcharging voltage of the 2V battery, and the target charging scheme is the charging scheme corresponding to the 2V battery.
For example, the rechargeable battery may have three specifications, and the rated voltages are 6V, 8V and 12V, wherein the voltage fluctuation range of the rechargeable battery with the rated voltage of 6V is [5V, 7.2V ], the voltage fluctuation range of the rechargeable battery with the rated voltage of 8V is [6.2V, 9.7V ], the voltage fluctuation range of the rechargeable battery with the rated voltage of 12V is [7.9V, 14.6V ], that is, the voltage fluctuation ranges corresponding to the rechargeable batteries of two adjacent specifications overlap, the voltage intervals divided according to the voltage fluctuation ranges of the rechargeable batteries of the three specifications are [5V, 7.2V ], (7.2V, 9.7V ], (9.7V, 14.6V ], and the correspondence relationship between the preset voltage interval and the rated voltage and the overcharge voltage can be shown in table 2:
| voltage interval | Rated voltage | Overcharge voltage |
| [5V，7.2V] | 6V/8V | Overcharge voltage of 6V battery |
| (7.2V，9.7V] | 8V/12V | Overcharge voltage of 8V battery |
| (9.7V，14.6V] | 12V | Overcharge voltage of 12V battery |
TABLE 2
If it is detected that the initial battery voltage of the accessed rechargeable battery is 7.9V and the voltage interval to which the 7.9V belongs is (7.2V, 9.7V), the accessed first rated voltage is 8V, the second rated voltage is 12V, the overcharge voltage is the overcharge voltage of the 8V battery, and the target charging scheme is the charging scheme of the 8V battery according to the correspondence shown in table 2.
In an alternative embodiment, charging schemes of the rechargeable battery of various specifications may also be preset, where a charging scheme refers to the magnitude of the charging voltage output to the rechargeable battery and/or the magnitude of the charging current output in different charging phases, where the charging phases may be divided according to the charging time length, and the charging phases may also be divided according to the battery voltage of the rechargeable battery. For example, charging for 1-10 minutes is used as the first charging stage, charging for 10-60 minutes is used as the second charging stage, and so on; for another example, a 6V battery is charged, a time period corresponding to a voltage of the battery in the range of 4V to 5V is used as a first charging stage, a time period corresponding to a voltage of the battery in the range of 5V to 6V is used as a second charging stage, and so on. Among them, the charging scheme of the rechargeable battery of each specification can be designed according to the characteristics of the material, the attribute, and the like of the rechargeable battery.
S103, charging the rechargeable battery according to the target charging scheme, and detecting the battery voltage of the rechargeable battery.
In this case, the rechargeable battery may be charged according to the charging scheme described in step S102, for example, a charging phase of the rechargeable battery may be determined, then a charging voltage and/or a charging current to be output to the rechargeable battery during the charging phase may be determined according to the target charging scheme, and then a corresponding charging voltage and/or charging current may be output to charge the rechargeable battery.
In a specific implementation, the battery voltage of the rechargeable battery may be detected by a voltage detection circuit, where the method for detecting the battery voltage of the rechargeable battery may refer to the description of step S101, and is not described herein again.
And S104, temporarily stopping charging the rechargeable battery under the condition that the battery voltage of the rechargeable battery is equal to the target overcharge voltage.
In which the detected battery voltage may be compared with the overcharge voltage determined in step S101, and charging of the secondary battery may be temporarily stopped when the battery voltage is determined to be equal to the target overcharge voltage.
In a specific implementation, charging the rechargeable battery can be stopped by opening a relay in the charging loop.
And S105, determining the voltage drop amplitude of the rechargeable battery.
The battery voltage of the rechargeable battery can be detected after a preset time period, and the difference value between the battery voltage and the target overcharge voltage is determined as a voltage drop amplitude.
The preset time is a time which accords with the dropping rule of the rechargeable battery.
And S106, stopping or continuing to charge the rechargeable battery according to the voltage drop amplitude of the rechargeable battery.
In a possible scenario, under the condition that voltage fluctuation ranges corresponding to the rechargeable batteries of different specifications do not coincide with each other, only one rated voltage is determined according to a voltage interval to which the initial battery voltage belongs, that is, the accessed rechargeable battery is only possibly a rechargeable battery of one specification, and accordingly, a voltage drop amplitude is only possible, that is, the voltage drop amplitude is the voltage drop amplitude of the rechargeable battery of which the rated voltage is the rated voltage corresponding to the voltage interval to which the initial battery voltage belongs, and charging of the rechargeable battery is stopped because the charging voltage of the rechargeable battery reaches the overcharge voltage of the rechargeable battery.
In another possible scenario, under the condition that voltage fluctuation ranges corresponding to two adjacent specifications of rechargeable batteries overlap, two kinds of rated voltages are determined according to a voltage interval to which the initial battery voltage belongs, namely, an accessed rechargeable battery may be one of the two adjacent specifications of rechargeable batteries, correspondingly, two possibilities exist in a voltage drop amplitude, a target overcharging voltage is a charging voltage corresponding to a rechargeable battery with a smaller rated voltage of the two specifications of rechargeable batteries, and if the rechargeable battery is determined to be the rechargeable battery with the smaller rated voltage of the two specifications of rechargeable batteries according to the voltage drop amplitude, the rechargeable battery is stopped to be charged; and if the rechargeable battery is determined to be the rechargeable battery with higher rated voltage in the two specifications of rechargeable batteries according to the voltage drop amplitude, continuing to charge the rechargeable battery.
After the rechargeable battery is determined to be the rechargeable battery with a larger rated voltage in the rechargeable batteries with two specifications, because the target charging scheme and the target overcharging voltage adopted in the previous step correspond to the rechargeable battery with a smaller rated voltage, the rechargeable battery cannot be fully charged by continuously using the target charging scheme, and the rechargeable battery is continuously charged by adopting the target charging scheme of the rechargeable battery with a larger rated voltage, wherein the step of continuously charging the rechargeable battery comprises the following steps: determining a charging scheme corresponding to the second rated voltage as a target charging scheme, and determining an overcharging voltage corresponding to the second rated voltage as a target overcharging voltage; continuing to charge the rechargeable battery according to the target charging scheme until the battery voltage of the rechargeable battery equals the target overcharge voltage. And when the battery voltage of the rechargeable battery reaches the overcharge voltage corresponding to the second rated voltage, the rechargeable battery is fully charged.
In the embodiment of the invention, one or two possible specifications of the rechargeable battery can be preliminarily determined by obtaining the initial battery voltage of the rechargeable battery, so that the charging scheme and the overcharge voltage of the rechargeable battery suitable for the one or two specifications can be determined, then the rechargeable battery is charged according to the charging scheme until the voltage of the rechargeable battery reaches the target overcharge voltage, the charging of the rechargeable battery is temporarily stopped to detect the voltage drop amplitude of the rechargeable battery, the specification of the rechargeable battery can be further determined according to the voltage drop amplitude, whether the rechargeable battery is fully charged or not can be determined according to the determined specification of the rechargeable battery, so that the phenomenon that the rechargeable battery is over-charged or not fully charged due to the fact that the rechargeable battery is charged under the condition that the specification of the rechargeable battery is not known is avoided.
Referring to fig. 4, fig. 4 is a schematic flow chart of another charging method of the present invention, which is suitable for a scenario where voltage fluctuation ranges of two adjacent rechargeable batteries of different specifications overlap, as shown in the figure, the method includes:
s201, detecting the initial battery voltage of the rechargeable battery under the condition that the rechargeable battery is accessed.
S202, determining a target charging scheme and a target overcharge voltage according to the initial battery voltage.
S203, charging the rechargeable battery according to the target charging scheme, and detecting the battery voltage of the rechargeable battery.
And S204, temporarily stopping charging the rechargeable battery under the condition that the battery voltage of the rechargeable battery is equal to the target overcharge voltage.
And S205, determining the voltage drop amplitude of the rechargeable battery.
The specific implementation manner of steps S201 to S205 may refer to the description of steps S101 to S105 in the method embodiment corresponding to fig. 1, and is not described herein again.
Through steps S201 to S205, two kinds of rated voltages are determined according to the voltage interval to which the initial battery voltage belongs, and accordingly, two possibilities exist for the voltage drop amplitude.
S206, determining the voltage interval to which the initial battery voltage belongs.
The voltage interval may be preset, and the description of the voltage interval may refer to the description of step S102 in the method embodiment corresponding to fig. 1, which is not described herein again.
And S207, determining a preset voltage drop threshold corresponding to the voltage interval.
According to the characteristics of the rechargeable batteries, when the rechargeable batteries with different specifications are charged to the same battery voltage, the voltage drop amplitudes of the rechargeable batteries with different specifications are different, wherein in the rechargeable batteries with two specifications, the drop amplitude of the rechargeable battery with higher rated voltage is larger than the drop amplitude of the rechargeable battery with lower rated voltage, a preset voltage drop threshold value can be set according to the voltage drop amplitude of the rechargeable batteries with two specifications when the battery voltages with two specifications are charged to a target overcharge voltage, wherein the target overcharge voltage is the overcharge voltage corresponding to the rechargeable battery with lower rated voltage in the rechargeable batteries with two specifications, and then the corresponding relation among the preset voltage drop threshold value, the overcharge voltage and the voltage interval is preset.
For example, the rechargeable battery may have three specifications, and the rated voltages are 6V, 8V and 12V, respectively, wherein the corresponding relationship between the rated voltage and the overcharge voltage is shown in table 3:
| rated voltage | Overcharge voltage |
| 6V | 7.8V |
| 8V | 10.266V |
| 12V | 15.4V |
TABLE 3
When the 6V and 8V rechargeable batteries are charged to 7.8V, the drop amplitude of the 6V battery is less than or equal to 0.6V, and the drop amplitude of the 8V battery is greater than 0.6V; when 10.266V is charged by the 8V and 12V rechargeable batteries, the drop amplitude of the 8V battery is smaller than 0.8V, the drop amplitude of the 12V battery is larger than 0.8V, at this time, 0.6V can be used as a preset voltage drop threshold value for distinguishing the 6V battery from the 8V battery, 0.8V is used as a preset drop threshold value of the 8V battery and the 12V battery, and the preset corresponding relation among the preset voltage drop threshold value, the overcharging voltage and the voltage interval can be shown in a table 4:
| voltage interval | Presetting voltage drop threshold | Overcharge voltage |
| [5V，7.2V] | 0.6V | Overcharge voltage of 6V battery |
| (7.2V，9.7V] | 0.8V | Overcharge voltage of 8V battery |
| (9.7V，14.6V] | Overcharge voltage of 12V battery |
TABLE 4
And if the voltage interval is (7.2V, 9.7V ], determining that the preset voltage drop threshold is 0.8V.
And S208, if the voltage drop amplitude is smaller than or equal to the preset voltage drop threshold, stopping charging the rechargeable battery.
For example, if the voltage drop amplitude is 0.5V, the voltage drop threshold is 0.8V, and the voltage drop amplitude is smaller than the preset voltage drop threshold, the charging of the rechargeable battery is stopped.
In an alternative embodiment, after the rechargeable battery is stopped being charged, a full charge indication may be output through a voice prompt, a text prompt, an image prompt, an indicator light prompt, or the like, for example, the voice prompt indicates that the rechargeable battery is full, and for example, the rechargeable battery is displayed on the display screen with a charge of 100%, and the like.
And S209, if the voltage drop amplitude is larger than the preset voltage drop threshold value, continuing to charge the rechargeable battery.
For example, if the voltage drop amplitude is 0.9V, the voltage drop threshold is 0.8V, and the voltage drop amplitude is greater than the preset voltage drop threshold, the rechargeable battery continues to be charged.
The specific implementation manner of continuing to charge the rechargeable battery may refer to the description of step S106 in the method embodiment corresponding to fig. 1, and is not described herein again.
In the embodiment of the invention, two possible specifications of the rechargeable battery can be preliminarily determined by acquiring the initial battery voltage of the rechargeable battery, so that a target charging scheme and a target overcharge voltage of the rechargeable battery suitable for the two specifications can be determined, then the rechargeable battery is charged according to the charging scheme until the voltage of the rechargeable battery reaches the overcharge voltage, the charging of the rechargeable battery is temporarily stopped to detect the voltage drop amplitude of the rechargeable battery, because the voltage drop amplitudes of the rechargeable batteries with different specifications are different when the rechargeable batteries with different specifications are charged to the same battery voltage, whether the charging is continued or not can be determined according to the relation between the voltage drop amplitude and the preset voltage drop threshold value, the charging of the rechargeable battery is stopped when the voltage drop amplitude is less than or equal to the preset voltage drop threshold value, the overcharging is avoided, and under the condition that the voltage drop amplitude is greater than the preset voltage drop threshold value, and the rechargeable battery is continuously charged, so that the situation of insufficient charging is avoided.
