[0019] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0020] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The main solution of the embodiment of the present application is: when detecting connection with the battery, collecting the initial voltage of the battery and initially charging the battery; collecting the first current current and the first current loaded voltage of the battery; determining the target battery type of the battery based on the first current current, the initial voltage and the first current loaded voltage; based on the target battery type, determining the charging parameters corresponding to the target battery type, and charging the battery using the charging parameters.

[0022] In this embodiment, for the convenience of description, the following description is made with the charger as the execution subject.

[0023] Currently, batteries are a common component used to generate electrical energy and are widely used in various mobile devices. There are many types of batteries, including lithium batteries, lead-acid batteries, and nickel-cadmium batteries. Different batteries have different electrical characteristics, so they require different electrical parameters such as charging voltage and charging current for charging. However, existing chargers are unable to accurately identify the type of connected battery, resulting in safety hazards when charging the battery.

[0024] The present application provides a solution. Since different types of batteries have unique electrical characteristics, the reaction characteristics of the battery, such as internal impedance and voltage changes, can be analyzed based on the initial voltage of the battery when it is connected to the charger, and the first current current and the first current load voltage after the initial charging. Parameters, so as to infer the target battery type of the battery based on the internal impedance and voltage changes of the battery. At the same time, after determining the target battery type of the battery, the charging parameters such as charging voltage, charging current, and charging time suitable for the battery can be determined according to the target battery type, which can not only effectively improve the charging efficiency and extend the battery life, but also avoid overcharging, over-discharging or using inappropriate charging current, reduce the risk of thermal runaway and damage, and avoid safety hazards when charging the battery.

[0025] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a charger, etc. The charger is taken as an example to illustrate this embodiment and the following embodiments.

[0026] Embodiments of the present application In the following, the charger used in the technical implementation of the present application will be described: Reference Figure 1 , Figure 1 The internal structure diagram of the charger is shown in Figure 1. The charger includes battery connection terminals, voltage detection circuit, current detection circuit, relay, power circuit and microprocessor controller.

[0027] The battery connection terminals are respectively connected to the microprocessor controller, the voltage detection circuit, the current detection circuit and the relay, and the battery connection terminals are used to connect to the battery.

[0028] The voltage detection circuit is connected to the microprocessor controller and the battery connection terminal respectively. The voltage detection circuit includes a high-precision voltage divider circuit and an analog-to-digital converter (ADC). After the voltage detection circuit collects the initial voltage and the loaded voltage of the battery through the voltage divider circuit, the analog-to-digital converter is used to convert the initial voltage and the loaded voltage into voltage digital signals, and the digital signals are transmitted to the microprocessor controller.

[0029] The current detection circuit is connected to the microprocessor controller and the battery connection terminal respectively. The current detection circuit includes a high-precision current sampling circuit and an analog-to-digital converter (ADC). After the current detection circuit collects the current when the battery is charging through the current sampling circuit, the analog-to-digital converter converts the current value into a current digital signal, and transmits the current digital signal to the microprocessor controller.

[0030] The relay is connected to the microprocessor controller, the battery connection terminal and the power circuit respectively. The relay is used to stop charging the battery or continue charging the battery according to the control signal when receiving the control signal sent by the microprocessor controller.

[0031] The power circuit is connected to the microprocessor controller, and the power circuit is used to output current and voltage under the control of the microprocessor controller.

[0032] When the microprocessor controller detects that the battery is connected through the battery connection terminal, it receives the voltage digital signal of the initial voltage sent by the voltage detection circuit, and controls the power circuit to output the current and voltage to initially charge the battery. After the battery is initially charged, it receives the voltage digital signal of the first current loaded voltage sent by the voltage detection circuit, receives the current digital signal of the first current current sent by the current detection circuit, and determines the target battery type of the battery based on the first current current, the first current loaded voltage, and the initial voltage. After determining the target battery type of the battery, the charging parameters corresponding to the target battery type can be determined, and the current and voltage output by the power circuit can be controlled based on the charging parameters.

[0033] In this embodiment, the reaction characteristics of the battery, such as the internal impedance and voltage change, can be analyzed based on the initial voltage of the battery when it is connected to the charger, and the first current current and the first current load voltage after the initial charging, so as to infer the target battery type of the battery based on the internal impedance and voltage change of the battery. At the same time, after determining the target battery type of the battery, the charging parameters such as the charging voltage, charging current, and charging time suitable for the battery can be determined based on the target battery type, which can not only effectively improve the charging efficiency and extend the battery life, but also avoid overcharging, over-discharging or using inappropriate charging current, reduce the risk of thermal runaway and damage, and avoid safety hazards when charging the battery.

[0034] In addition, when charging the battery, the voltage and current output by the power circuit can be adaptively adjusted using the charging parameters, so that the charger can adapt to batteries of different types and states, thereby improving the applicability of the charger.

[0035] Based on this, the present application embodiment provides a battery charging method, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the battery charging method of the present application.

[0036] In this embodiment, the battery charging method includes steps S10 to S40: Step S10, when the connection with the battery is detected, the initial voltage of the battery is collected, and the battery is initially charged.

[0037] Step S20, collecting a first current current and a first current load voltage of the battery.

[0038] In this embodiment, the initial voltage may be the voltage of the battery before charging. The first current loaded voltage may be the voltage of the battery at the current moment after the battery is connected to the charger and starts charging. The first current current may be the current passing through the battery at the current moment after the battery is connected to the charger and starts charging.

[0039] Specifically, when the charger detects that it is connected to the battery through the battery connection terminal, it can collect the initial voltage of the battery through the voltage detection circuit and control the power circuit to output current and voltage to perform initial charging on the battery.

[0040] It should be noted that when the battery is initially charged, in order to reduce battery short circuit or other safety risks and ensure a safer charging process, further, as an optional implementation, the initial charging of the battery can be adaptively changed to constant current charging of the battery, that is, the battery is charged using a set initial constant current value.

[0041] After the battery is initially charged, a first current load voltage of the battery may be collected through a voltage detection circuit, and a first current current passing through the battery may be collected through a current detection circuit.

[0042] Step S30, determining a target battery type of the battery based on the first current current, the initial voltage and the first current loaded voltage.

[0043] It is understandable that different types of batteries (such as lithium-ion, lead-acid, nickel-metal hydride, etc.) have different internal resistance characteristics. Therefore, when determining the target battery type of the battery based on the first current current, the initial voltage, and the first current loaded voltage, the first internal resistance of the battery can be determined based on the first current current, the initial voltage, and the first current loaded voltage. After determining the first internal resistance of the battery, a mapping relationship can be searched to determine the target battery type corresponding to the first internal resistance, that is, the voltage difference between the initial voltage and the first current loaded voltage is determined, and the first internal resistance of the battery is determined based on the voltage difference and the first current current; the mapping relationship is searched to determine the target battery type corresponding to the first internal resistance; wherein the mapping relationship includes a mapping relationship between the first internal resistance and the battery type.

[0044] Step S40: Based on the target battery type, a charging parameter corresponding to the target battery type is determined, and the battery is charged using the charging parameter.

[0045] When charging the battery using the charging parameters, in order to prevent the situation where the target battery type of the battery is incorrectly determined due to battery aging, further, as an optional implementation, after step S40, the method further includes: Step S41, when it is detected that the battery enters the next charging stage, a second current loaded voltage and a second current current of the battery are collected.

[0046] Step S42, stop charging the battery.

[0047] Step S43, collecting the third voltage of the battery.

[0048] Step S44, determining a second internal resistance of the battery using the third voltage, the second current load voltage, and the second current current.

[0049] Step S45, searching for a mapping relationship to determine a new battery type corresponding to the second internal resistance.

[0050] Step S46, determining whether the new battery type is consistent with the target battery type.

[0051] Step S47: If the new battery type is inconsistent with the target battery type, stop charging the battery.

[0052] Step S48: If the new battery type is consistent with the target battery type, the battery is charged in the next charging stage.

[0053] Specifically, the battery charging process is mainly divided into three charging stages: trickle current stage, constant current stage and constant voltage stage. During the battery charging process, the battery voltage can be used to determine whether the battery enters the next charging stage.

[0054] For example, the battery voltage of the battery can be collected through a voltage detection circuit. After the battery voltage is collected, the charging stage of the battery can be determined according to the battery voltage range corresponding to each charging stage. For example, when the battery voltage is 3.9V, and the battery voltage in the trickle stage is lower than 3V, the battery voltage in the constant current stage is 3.0V to 4.2V, and the battery voltage in the constant voltage stage is not lower than 4.2V, it can be determined that the charging stage of the battery is the constant current stage.

[0055] When it is detected that the battery enters the next charging stage, the second current load voltage of the battery can be collected through the voltage detection circuit, and the second current current of the battery can be collected through the current detection circuit. After collecting the second current load voltage and the second current current of the battery, the relay can be controlled to disconnect, stop charging the battery, and collect the third voltage of the battery. When the battery is stopped from charging, the voltage of the battery may fluctuate instantaneously. In order to obtain a more accurate battery voltage, step S43 can be adaptively changed to: after stopping charging for a preset time, collect the third voltage of the battery, such as collecting the third voltage of the battery through the voltage detection circuit after stopping charging for 2-3 seconds.

[0056] After obtaining the third voltage, the second current loaded voltage, and the second current current of the battery, the voltage difference between the second current loaded voltage and the third voltage can be determined, and based on the voltage difference between the second current loaded voltage and the third voltage and the second current current, the second internal resistance of the battery can be determined. After obtaining the second internal resistance, a mapping relationship can be searched to determine a new battery type corresponding to the second internal resistance, and to determine whether the new battery type is consistent with the target battery type.

[0057] When the new battery type is inconsistent with the target battery type, the battery may be aged and cause a detection error. In order to avoid equipment failure due to charging mismatch, the battery is stopped from being charged. When the new battery type is consistent with the target battery type, there is no battery detection error, and the battery is charged to the next stage.

[0058] In this embodiment, when the battery enters the next stage, the second internal resistance of the battery is determined based on the third voltage, the second current loaded voltage and the second current current, and the new battery type of the battery is determined using the second internal resistance to determine whether the new battery type is consistent with the target battery type. Based on the comparison result, it is determined whether to continue charging the battery. That is, when the battery enters the next charging stage, the battery type of the battery will be identified to avoid detection errors due to battery aging, thereby ensuring the accuracy of battery type identification.

[0059] It is understandable that different battery types have specific charging requirements, such as voltage, current and charging time. If mismatched charging parameters are used, it may cause overcharging, short circuit or other safety hazards, or even cause fire or explosion. After determining the target battery type of the battery, it can be determined whether there are charging parameters corresponding to the target battery type in the charging data stored in the charger. When there are charging parameters corresponding to the target battery type, the battery is charged using the charging parameters. When there are no charging parameters corresponding to the target battery type, the battery is stopped from being charged, that is, it is determined whether there are charging parameters corresponding to the target battery type. If there are charging parameters corresponding to the target battery type, the battery is charged using the charging parameters. If there are no charging parameters corresponding to the target battery type, the battery is stopped from being charged.

[0060] In this embodiment, since different types of batteries have unique electrical characteristics, the reaction characteristics of the battery, such as internal impedance and voltage changes, can be analyzed based on the initial voltage of the battery when it is connected to the charger, and the first current current and the first current load voltage after the initial charging, so as to infer the target battery type of the battery based on the internal impedance and voltage changes of the battery. At the same time, after determining the target battery type of the battery, the charging parameters such as the charging voltage, charging current, and charging time suitable for the battery can be determined based on the target battery type, which can not only effectively improve the charging efficiency and extend the battery life, but also avoid overcharging, over-discharging or using inappropriate charging current, reduce the risk of thermal runaway and damage, and avoid safety hazards when charging the battery.
