Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In order to facilitate those skilled in the art to understand the technical solutions provided by the embodiments of the present disclosure, a technical environment for implementing the technical solutions is described below.
The battery pack materials are various, and the currently commonly used lithium ion battery pack materials comprise ternary lithium and lithium iron phosphate, and the nominal voltage value, the highest charging voltage (highest cut-off voltage) and the lowest charging voltage (lowest cut-off voltage) of the ternary lithium and the lithium iron phosphate are different. For example, the nominal voltage of lithium iron phosphate is 3.25V, and the nominal voltage of the ternary lithium battery is 3.7V. The highest charging voltage of the battery packs is different even though the nominal voltages of the battery packs are the same. For example, the maximum charge voltage of a 60V nominal lithium iron phosphate battery is 73V, while the maximum charge voltage of a 60V nominal ternary lithium battery is 71.4V. Therefore, even if the battery packs made of various materials have the same voltage level, corresponding chargers must be configured, and the chargers are incompatible with each other, which causes waste of resources. When a battery pack and a charger made of various materials and various charging voltages are mixed, the wrong charger is easy to use, and hidden dangers such as insufficient battery pack charging, battery pack fire explosion caused by overcharge of the battery pack, fire hazard and the like which endanger the life and property safety of a user can occur. The two chargers cannot be used in common during charging of the lithium iron phosphate battery pack with the nominal voltage of 60V and the ternary lithium battery pack with the nominal voltage of 60V. If a ternary lithium charger is used for charging the lithium iron phosphate battery pack, the charging is insufficient, so that the endurance mileage is shortened; when the lithium iron phosphate battery charger is used for charging the ternary lithium battery pack, although the BMS system is arranged in the lithium battery, if the ternary lithium battery pack is charged by long-term overvoltage or the BMS system fails, safety accidents such as overcharge, fire explosion and the like of the ternary lithium battery pack can be caused, and the life safety of a user and the property safety of a use place are threatened. At present, fire accidents caused by battery charging occur in all big, medium and small cities in China, and a large amount of property loss is caused due to loss of many people. In the related art, a charger for controlling charging through communication is adopted, because a communication program needs to be written, and a communication function needs to be added to a BMS in a battery pack, the production cost of the battery pack is increased, communication protocols of different production enterprises are difficult to unify, most BMSs in finished lithium ion battery packs on the market do not have a self-contained communication function at present, and a barrier is also caused to the compatible use of the charger in the mode.
Based on practical technical needs similar to those described above, the present disclosure provides a charging method, a charging circuit, and a charging device.
Fig. 1 is a flowchart illustrating a charging method, as shown in fig. 1, for use in a terminal, according to an exemplary embodiment, including the following steps.
And step S11, obtaining the parameter value of the preset marking component in the power receiving module.
In the embodiment of the present disclosure, the power receiving module may include a power storage device such as a battery or a battery pack, and may also include other non-power storage devices such as a household appliance and a public facility. The marking element may include an inductance element, a resistance element, a capacitance element, an NFC chip, and the like, and the corresponding parameter may include an inductance, a resistance, a capacitance, or an electromagnetic signal. The obtaining of the parameter value of the preset marking component in the power receiving module may include, in one example, obtaining the parameter value of the marking component by electrically connecting, for example, connecting a resistor to a circuit to test the magnitude of the resistance value; in another example, the electromagnetic signal within the NFC chip may be provided by a non-connected means, such as near field communication technology of NFC.
Step S12, determining the charging voltage of the powered module according to the preset association relationship between the parameter value and the charging voltage of the powered module.
In the embodiment of the present disclosure, the marking component plays a role in marking and identifying, and has a preset association relationship with the charging voltage of the power receiving module. In one example, the correlation may include a one-to-one correspondence, such as a resistance of 1.2K Ω to a charging voltage of 56.7-88.2V, and a resistance of 2.4K Ω to a charging voltage of 60-87.6V. In another example, the correlation may also include a many-to-one correspondence, such as resistances 1.2K Ω and 2.4K Ω both corresponding to 56.7-88.2V.
In the embodiment of the present disclosure, the charging voltage may include a specific voltage value, and may also include a voltage range, which is determined according to the property of the power receiving module. When the charging voltage is actually set, a specific voltage value or voltage range may be determined to be set according to physical properties of the power receiving module. By obtaining the parameter value of the marking component, the charging voltage of the power receiving module can be determined according to the preset association relation between the parameter value and the charging voltage. Table 1 shows a correlation between a parameter value and a charging voltage preset of a power receiving module according to an exemplary embodiment.
Referring to table 1, the battery specification list shows the type of the labeled component, the resistance is a parameter of the labeled component, the value of the resistance has a one-to-one correspondence relationship with the charging voltage range, and the charging voltage range shows the acceptable charging voltage of the labeled component.
Step S13 is to charge the power receiving module according to the charging voltage.
In the embodiment of the present disclosure, the power receiving module is charged, in one example, interfaces may be respectively disposed at a charging end and a power receiving end in a circuit connection manner, and the two interfaces are in contact with each other to implement circuit connection; in another example, the charging may also be performed wirelessly, and the wireless charging technology may include an electromagnetic induction charging technology, a magnetic field resonance technology, and a radio electromagnetic wave technology.

Thus, the voltage in the charging circuit can be detected in real time, in one example, if the voltage is greater than the charging voltage range, the switching amplitude of the transformer is reduced to be within the charging voltage range, and in another example, if the voltage is less than the charging voltage range, the switching amplitude of the transformer is increased to be within the charging voltage range.
