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.
Along with the continuous development of intelligent equipment, the microprocessor dominant frequency, the display increase, the resolution ratio improvement and the camera pixel increase of terminal equipment, the power consumption of equipment increases, and power consumption speed also accelerates thereupon. In the early development stage, the requirement on charging power is low, and a terminal battery adopts a single connector for power supply. As the charging power increases, high-power charging is adopted to increase the charging time, and the current in the terminal battery increases due to the increase of the power, so that the heat loss increases. In order to reduce the power loss, the single connector of the terminal battery is gradually developed into a dual connector structure.
Fig. 1 is a schematic view illustrating a structure of a dual battery connector according to an exemplary embodiment of the present disclosure, and referring to fig. 1, the dual battery connector is divided into a master connector and a slave connector, and the master connector and the slave connector are in a parallel structure inside the battery. The master connector is mainly used for charging and discharging the battery, and the slave connector is used for charging. When the terminal battery is charged with high power, the charging current is distributed on the main connector and the auxiliary connector, so that the effect of reducing power consumption is achieved. When the terminal equipment is subjected to vibration, for example, falling, collision, or working in a high-temperature environment, the battery may be loosened, broken, or detached from the connector, and the connector cannot work normally. The terminal system and the user cannot know that the working state of the slave connector is abnormal, the terminal is continuously charged, the charging current completely passes through the main connector to the battery cell, and due to the large current of the main connector, large power consumption loss can be brought, and the use safety of the terminal is affected.
Therefore, the present disclosure provides a battery charging protection method, which detects the working state of the slave connector during the charging process of a terminal battery provided with the slave connector, and realizes the charging protection of the main connector of the battery when the abnormality of the connector is found in time, thereby improving the safety of the terminal.

In step S101, the operating state of the slave connector is determined during the charging of the terminal.
In step S102, if the operating state of the slave connector is determined to be abnormal, the master connector is protected from charging.
In the embodiment of the disclosure, during the charging process of the terminal, the working state of the slave connector is detected for the terminal battery provided with the slave connector, so as to determine whether the working state of the slave connector is normal. The main connector and the slave connector are in a parallel connection structure, the main connector is used for charging and discharging the battery, and the slave connector is used for charging the battery. The charging current from the terminal battery is distributed on the main connector and the auxiliary connector, so that the effect of reducing power consumption is achieved. When the working state of the connector is abnormal, the connector cannot share the charging current, the charging current enters the battery cell through the main connector, and the main connector bears the increased current, so that the power consumption is increased, and the use safety of the terminal is influenced.
It can be understood that the main connector is used for supplying power to the system, and if the working state of the main connector is abnormal, the system cannot be started for normal use when the system is powered off, so that the working state of the main connector does not need to be detected. And when the working state of the slave connector is abnormal, the master connector of the terminal battery is charged and protected, so that the safe charging of the terminal is realized.
According to the embodiment of the disclosure, for a terminal battery provided with a main connector and a slave connector, in the process of charging the terminal, the working state of the slave connector is detected, and if the slave connector is abnormal, the main connector of the battery is protected by charging, so that the safety of the system is improved, and the use safety risk caused by too fast temperature rise of the terminal battery is avoided.
Fig. 3 is a flowchart illustrating a method of determining an operating state of a slave connector according to an exemplary embodiment of the present disclosure, and referring to fig. 3, the method of determining an operating state of a slave connector includes the following steps.
In step S201, the electricity amount information of the electricity meter is read based on the integrated circuit bus communication protocol.
In step S202, the operating state of the slave connector is determined based on the power amount information reading result.
In the embodiment of the present disclosure, an electricity meter is disposed in a battery of the terminal, the electricity meter is used for monitoring a usage condition of the battery, detecting a state of the battery through the electricity meter, and obtaining related information such as a voltage, an electric quantity, and a temperature of the battery, and the electricity meter may be connected to a Central Processing Unit (CPU) of the terminal through a main connector or may be connected to the CPU of the terminal through a slave connector. The fuel gauge is communicated with a terminal CPU based on an Inter-Integrated Circuit (I2C) protocol, so that the CPU reads the relevant information of the fuel gauge.

The electricity meter is connected to the terminal CPU through the connector, and the terminal CPU reads the electricity quantity information of the electricity meter based on the I2C protocol. SCL and SDA are signal lines of an I2C bus, SDA is a bidirectional data line, and SCL is a clock line. When data is transmitted on the bus based on the I2C protocol, the transmission of the highest bit is carried out firstly, the host sends out a starting signal, and the SDA jumps from high level to low level during the high level of the SCL. And then, the host sends data of one byte, the host sends a stop signal after the data is transmitted, and the SDA jumps from low level to high level during the SCL high level, so that the terminal CPU reads the electric quantity information of the battery fuel gauge through an I2C protocol. And determining the working state of the slave connector based on the reading result of the terminal CPU reading the power information.
According to the embodiment of the disclosure, the terminal CPU reads the electric quantity information of the electric quantity meter through the I2C protocol, and determines the working state of the slave connector based on the electric quantity information reading result, so that when the working state of the slave connector is abnormal, the charging protection is carried out on the main connector of the battery, and the charging safety of the terminal is improved.
Fig. 5 is a flowchart illustrating a method of determining an operating state of a slave connector according to an exemplary embodiment of the present disclosure, and referring to fig. 5, the method of determining an operating state of a slave connector includes the following steps.
In step S301, the electricity amount information of the electricity meter is read based on the integrated circuit bus communication protocol.
In step S302, if the information on the amount of electricity of the electricity meter is read from the connector, it is determined that the operation state of the slave connector is normal.
In step S303, if the information on the amount of electricity of the electricity meter is not read from the slave connector, it is determined that the operation state of the slave connector is abnormal.
In the embodiment of the present disclosure, a fuel gauge provided in a battery of the terminal is connected to the terminal CPU through a slave connector, and the fuel gauge communicates with the terminal CPU based on the I2C protocol, causing the CPU to read the information of the amount of power of the fuel gauge. The CPU reads the electric quantity information of the battery fuel gauge through the I2C protocol, and determines whether the working state of the slave connector is normal or not based on the electric quantity information reading result. That is, when the CPU reads the electricity meter-related information from the connector, it is determined that the operating state of the connector at that time is normal. When the CPU cannot read the information related to the electricity meter through the slave connector, the CPU judges that the working state of the slave connector at the moment is abnormal. When the working state of the slave connector is abnormal, the charging current distributed by the main connector during high-power charging cannot be borne, and the main connector is protected in a charging mode in order to protect the charging safety of the battery.
According to the embodiment of the disclosure, the terminal CPU reads the electric quantity information of the electricity meter through the I2C protocol, and determines whether the working state of the slave connector is normal or not based on whether the relevant information of the electricity meter can be read normally or not, so that when the working state of the slave connector is abnormal, the main connector of the battery is protected for charging, and the charging safety of the terminal is improved.
According to the embodiment of the disclosure, the terminal CPU reads the electric quantity information of the electric quantity meter through the I2C protocol, and determines the working state of the slave connector based on the electric quantity information reading result, so that when the working state of the slave connector is abnormal, the charging protection is carried out on the main connector of the battery, and the charging safety of the terminal is improved.

In step S403, if the voltage does not exceed the voltage threshold range, it is determined that the operating state of the slave connector is normal.
In the embodiment of the disclosure, an electricity meter is arranged in the battery of the terminal so as to monitor the service condition of the battery in real time. The electricity meter may be connected to the terminal CPU through the master connector or may be connected to the terminal CPU through the slave connector. When the I2C communication protocol passes through the master connector to the terminal CPU, since the terminal CPU is not directly connected to the slave connector, it is impossible to determine whether the operating state of the slave connector is normal by using information on the amount of electricity that can be read from the connector to the electricity meter, which may be to detect the voltage of the slave connector during the charging process. When the voltage of the slave connector is detected to be in the voltage threshold range, the working state of the slave connector is judged to be normal, and when the voltage of the slave connector is detected to exceed the voltage threshold range, the working state of the slave connector is judged to be abnormal.

In the embodiment of the disclosure, during the charging process of the terminal, the working state of the slave connector is detected for the terminal battery provided with the slave connector, so as to determine whether the working state of the slave connector is normal. The main connector is used for supplying power to the system, and if the working state of the main connector is abnormal, the system cannot be started for normal use when the system is powered off, and the main connector can be easily found by a user in time. However, when the working state of the slave connector is abnormal, if the working state is not effectively detected, the current in the charging process enters the battery cell through the master connector, so that the master connector bears larger current. Therefore, when the working state of the slave connector is abnormal, the main connector of the terminal battery is charged and protected, the adaptive charging current of the adaptive main connector can be determined, and the battery of the terminal is charged through the main connector by the determined adaptive charging current, so that the charging safety of the terminal is realized.
