At present, along with the increase of the popularity of electronic devices, the demand of users for quick charging is higher and higher, and accordingly, the accuracy of the charging method in the quick charging process is more and more important. In practical applications, considering that the number of pins on the battery connector is limited, the voltage sensing lines of the master charging circuit and the slave charging circuit in the electronic device can sense the voltage at the voltage detection point (pack point), and the battery is charged according to the voltage at the pack point.
Because be provided with the battery protection shield between battery cell end (cell point) and the battery link, there is the difference in the voltage of battery cell point and the voltage of pack point department, leads to the unable assurance of the degree of accuracy of charging process.
In order to solve the above technical problem, an embodiment of the present disclosure provides a battery charging method, which may be applied to an electronic device including a battery with a built-in fuel gauge, and fig. 1 is a schematic structural diagram of an electronic device according to an exemplary embodiment. Referring to fig. 1, the electronic device includes a main board and a battery. The battery comprises an electric core, an electricity meter and a protection board, wherein the electricity meter is connected with the electric core through a sensing line and a voltage detection point cell, and charging data of the electric core can be obtained through sensing voltage and current of the cell point. The electricity meter is connected with the processor on the mainboard through a communication line. The protection shield is connected with electric core, is connected with the module that charges on the mainboard simultaneously. The communication line may be selected according to a specific scenario, and in one example, may be implemented by using an I2C bus.
The charging module on the mainboard can comprise a master charger and a slave charger. The main charger is connected with the power adapter and the battery middle protection plate respectively, can be realized by hardware, such as a DCDC circuit, is used for realizing closed-loop detection and stabilization of output voltage or current, and can be used in trickle charge, pre-charge and low-current constant-voltage (CV) charge stages.
The slave charger is connected with the power adapter and the battery protection plate respectively, and can be realized by adopting a charge pump (charge pump), so that the charging efficiency is higher. In order to maintain the efficient charging from the charger, the processor needs to poll the fuel gauge and generate charging configuration information according to charging data fed back by the fuel gauge, so that the output of the power adapter is configured and controlled to realize closed-loop control, and the closed-loop control method can be used for a CC stage with large charging current and a CV stage with large current. The large-current charging refers to a charging scene in which the current exceeds a set current threshold (such as 1A or 2A).
In this embodiment, the master charger and the slave charger may collect the voltage at the voltage detection point pack through the respective sensing lines.
Based on the above electronic device, the present disclosure provides a battery charging method, and fig. 2 is a battery charging method according to an exemplary embodiment. Referring to fig. 2, a battery charging method includes steps 21 to 23, wherein:
in step 21, sending an inquiry request to a fuel gauge in the battery, and the fuel gauge acquires the charging data of the battery core according to the inquiry request and feeds the charging data back to the processor; the charging data is voltage and/or current obtained by the electricity meter through detecting the electric core through a sensing line.
In this embodiment, during the charging process, the processor in the electronic device may send an inquiry request to the electricity meter in the battery according to a set period. After receiving the query request, the electricity meter may acquire the voltage and/or current of the electric core according to the query request to obtain charging data, and feed back the charging data to the processor through the communication line.
In step 22, charging data returned by the fuel gauge is received.
In step 23, charging configuration information is generated according to the charging data, and the charging configuration information is used for configuring the voltage and/or current provided by the charging adapter to the charging module.
In this embodiment, after receiving the charging data, the processor may generate charging configuration information, which may include:
in one example, referring to fig. 3, in step 31, the processor may obtain a voltage range for each charging phase. The charging phases may include a constant current phase 1(CCstep1), a constant current phase 2(CCstep2), a constant current phase 3(CCstep3), a constant current phase 4(CCstep4), a slave charger constant voltage phase (slave charger CV), a master charger constant voltage phase (main charger CV), and the like, and may be set according to specific scenarios. In step 32, the processor may obtain a voltage range to which the voltage value belongs in the charging data. In step 33, the processor may determine a charging phase from the voltage range. In step 34, the processor may generate charging configuration information according to the charging phase. The processor may then send the charging configuration information to the power adapter via the communication line, such that the power adapter may adjust the output voltage and/or output current based on the charging configuration information.
In another example, considering a scenario where the slave charger is suitable for high current (over 1A or 2A) charging, the processor may send a query request to the fuel gauge, which collects the cell point voltage and feeds it back to the processor. When the voltage is smaller than a first voltage threshold (e.g., 3V to 4V), the processor may generate the cell constant voltage charging configuration information. The power adapter may output a corresponding voltage and a large current in response to the cell constant voltage charging configuration information, so that the slave charger is charged with the large current, and the cell voltage is stabilized near a second voltage threshold (e.g., 4.25V), thereby achieving a higher charging efficiency.
In yet another example, the processor may also implement Over Voltage Protection (OVP) for the cell spot using the fuel gauge. The processor may obtain the voltage at the cell point, compare the voltage to a third voltage threshold (e.g., 4.48V), and if the voltage exceeds the third voltage threshold, the processor may generate the over-voltage protection configuration information and send the over-voltage protection configuration information to the power adapter. The power adapter can respond to the overvoltage protection configuration information, reduce the output voltage and limit the output current, or stop charging, and the voltage at a cell point can be ensured to be constant or to be reduced by limiting the output current or stopping charging until a fourth voltage threshold is reached, wherein the fourth voltage threshold is smaller than the third voltage threshold. When the processor determines that the voltage at the cell point is reduced to the fourth voltage threshold, charging configuration information can be generated according to the voltage at the cell point, namely, normal charging is recovered, and the overvoltage protection function is turned off.
In practical application, the third voltage threshold may be smaller than a voltage threshold of a hardware overvoltage protection circuit on the motherboard, and the battery may be continuously charged in a current-limiting manner under the condition of overvoltage, so as to prevent the hardware overvoltage protection circuit from stopping charging. In other words, in this example, a layer of overvoltage protection soft protection is added to the cell point, and then the safety of battery charging is improved by combining with hardware overvoltage protection.
In yet another example, the processor may also implement over-current protection (OCP) for the cell point using the fuel gauge. The processor may obtain the current at the cell point, compare the voltage to a current threshold (e.g., 3A), and if the current exceeds the current threshold, the processor may generate overcurrent protection configuration information and send the overcurrent protection configuration information to the power adapter. The power adapter can respond to the overcurrent protection configuration information, reduce the output current, or stop charging, and can ensure that the current at a cell point is smaller than a current threshold value by reducing the output current or stopping charging, so that the problem of current fluctuation when hardware is short-circuited in the constant-voltage charging process can be avoided, and the effect of protecting the battery cell is achieved.
In practical application, the current threshold value can be smaller than that of a hardware overcurrent protection circuit on a mainboard, so that damage of a large current to a battery cell when the hardware overcurrent protection circuit is not started is avoided. In other words, in this example, a layer of overcurrent protection soft protection is added to the cell point, and then the safety of battery charging is improved by combining with hardware overvoltage protection.
To this end, in the embodiment of the present disclosure, by sending an inquiry request to a fuel gauge in a battery, the fuel gauge may detect charging data, such as voltage and/or data, of a battery cell through a sensing line; then, charging configuration information can be generated according to the charging data so as to configure the voltage and/or current provided by the charging adapter to the charging module. In this embodiment, the battery voltage can be controlled more accurately by controlling the charging process using the cell voltage, which is beneficial to improving the accuracy of the charging process.
The battery charging method is described below in combination with a scenario in which the master charger and the slave charger respectively collect voltages at the voltage detection points pack through the sensing lines and report the voltages to the processor. The processor sends an inquiry request to the electricity meter and acquires the voltage of the cell point fed back by the electricity meter. And the processor determines that the battery cell can be charged by adopting large current according to the pack point voltage and the cell point voltage.
And in the first stage, the pack point is charged at a constant voltage. In the first phase, the processor generates charging configuration information, so that the voltage at the pack point is stabilized at 4.48V, and the battery cell is continuously charged by adopting a large current (such as 2A). During charging, the processor acquires the cell point voltage through the polling coulometer, and the voltage is in a rising state.
And in the second stage, the cell point is charged at constant voltage. In the second stage, when the voltage of the cell point reaches the voltage threshold (for example, 4.25V) in the constant voltage charging process of the pack point, the processor generates the configuration information of the constant voltage charging of the cell point, and the power adapter slowly reduces the output current, so that the charging current of the battery cell is reduced. Thus, the pack point voltage will slowly decrease until the battery is completely charged.
Therefore, in the embodiment, the battery is charged in a pack point and cell point voltage mode, which is beneficial to shortening the charging time and ensuring the safety degree of the charging process.
