Fig. 1 is a flowchart of a battery management method according to an embodiment of the present disclosure, where the method may be performed by a battery management device, and the device may be implemented in software and/or hardware, and may be generally integrated in an electronic device. The method is applied to electronic equipment with long-distance power supply, wherein in the embodiment of the disclosure, the long-distance power supply means that the length of a power line exceeds a preset length threshold, and voltage drop caused by the power line affects the charging speed of a battery. In some embodiments, referring to fig. 2, the electronic device may be a Virtual Reality (VR) all-in-one machine 10, where the battery 11 is designed in a rear-mounted manner, so that the weight distribution of the VR all-in-one machine 10 is relatively uniform, and the wearing comfort of the user is improved. In this type of VR all-in-one machine 10, the power cord is relatively long, typically more than 30cm, so that there is a relatively large voltage drop on the power cord, which affects the battery charging speed. In view of the technical problem, as shown in fig. 1, a battery management method provided in an embodiment of the present disclosure includes:
and 101, monitoring the charge and discharge states of a battery in the electronic equipment.
Typically, power management integrated circuits, i.e., universal power chips, such as PM8150B, are provided in electronic devices. The power management integrated circuit can charge a battery and also can utilize the electric energy output by the battery to supply power for each power utilization module on the main board. Accordingly, the charge and discharge states of the battery can be determined according to the operation states of the power management integrated circuit. Specifically, when the power management integrated circuit charges the battery, determining the charge and discharge state of the battery as the battery charge; when the power management integrated circuit supplies power to each power utilization module on the main board, the charging and discharging states of the battery are determined to be battery discharging. It should be noted that, in general, the charging speed of the battery is greater than the discharging speed of the battery, and if it is determined that the battery is charged and discharged simultaneously, the charging and discharging state of the battery is determined to be the charging state of the battery.
Additionally, in some embodiments, the charge and discharge state of the battery may be determined from a charge and discharge current on a power line between the power management integrated circuit and the battery. Illustratively, monitoring a charge-discharge current of the battery, and determining that the battery is charged when the charge current is greater than 0; when the discharge current is greater than 0, the battery is determined to be discharged.
Step 102, when the battery is charged, the voltage of the battery is obtained through a first analog-to-digital converter arranged at the battery end.
The first analog-to-digital converter can collect the analog voltage of the battery and convert the analog voltage into digital voltage, so that the battery voltage can be transmitted to a controller (such as a main control chip) on the main board in the form of a digital signal. Because the digital signal cannot change due to the increase of the transmission distance, the battery voltage obtained by the controller is the actual voltage of the battery, and the voltage drop caused by a longer power line is avoided.
Accordingly, in some embodiments, obtaining the battery voltage through a first analog-to-digital converter disposed at the battery terminal includes: converting the analog voltage of the battery terminal into a digital voltage through a first analog-to-digital converter; and receiving the digital voltage output by the first analog-to-digital converter, wherein the digital voltage is the battery voltage. For example, the controller may receive the battery voltage output by the first analog-to-digital converter via an integrated circuit bus (Inter-Integrated Circuit, I2C).
Step 103, controlling battery charging based on the battery voltage.
Currently, the battery charging process is divided into two phases: the battery is charged with constant current by adopting high current, and when the charging is close to tail sound, the battery is charged with constant voltage to avoid overcharge. For the electronic equipment with long-distance power supply, because a longer power line has larger voltage drop, when the controller controls the battery to charge according to the voltage of the main board end, the constant-current charging time is reduced, the constant-voltage charging time is increased, the constant-current charging is high-current quick charging, the charging speed is high, the constant-voltage charging is vortex slow charging, the charging speed is slower, therefore, the whole charging time is increased,
in the embodiment of the disclosure, the battery voltage obtained by the controller is the actual voltage of the battery, so that the influence of voltage drop on the power line is avoided, and therefore, in the process that the controller controls the battery to charge based on the battery voltage, the constant-current charging time can be increased, the constant-voltage charging time can be reduced, the overall charging time is shortened, and the charging efficiency is optimized. In some embodiments, the controller is capable of calculating a battery charge based on the battery voltage, thereby controlling battery charging based on the battery charge. Specifically, the controller battery voltage calculates the battery charge, and then sends a charge control signal to the power management integrated circuit based on the battery charge, and the power management integrated circuit charges the battery based on the charge control signal.
According to the battery management method provided by the embodiment of the disclosure, for the electronic equipment powered at a long distance, the battery end of the electronic equipment is provided with the analog-to-digital converter, namely the first analog-to-digital converter, and the first analog-to-digital converter is utilized to directly convert the actual analog voltage of the battery into the digital voltage (namely the battery voltage) and transmit the digital voltage to the controller, so that the controller can calculate the current actual electric quantity of the battery based on the battery voltage, and the calculation deviation of the electric quantity of the battery caused by the voltage drop on the power line is avoided, thereby accurately controlling the battery charging, reducing the battery charging time and improving the charging speed of the electronic equipment.
In some embodiments, the battery management method further comprises: when the battery discharges, acquiring the voltage of the main board through a second analog-to-digital converter arranged at the main board end; and controlling the electronic equipment to be powered off based on the mainboard voltage.
The main board voltage is the voltage when the battery voltage is transmitted to the main board or the power management integrated circuit through the power line, and the value of the main board voltage is the difference between the battery voltage and the voltage drop on the power line. In the embodiment, the voltage drop on the power line is taken into consideration, and the electronic equipment is controlled to be shut down based on the voltage of the main board, so that the actual voltage of the battery is not 0 or too low when the electronic equipment is shut down, the battery is prevented from overdischarging, the battery is protected, and the service life of the battery is prolonged.
Thus, the embodiment of the disclosure can acquire the voltage acquired by the corresponding analog-to-digital converter based on different charge and discharge states of the battery, so that the charge time can be reduced, and the battery can be prevented from being overcharged.
