Technical Field

Background
Most of the common rechargeable batteries in the market at present use compounds composed of nickel, zinc, cadmium, lithium and other elements as the positive or negative electrode materials of the batteries.

In the prior art, the voltage or capacity of the battery is usually monitored by adding an additional catalyst or electrolyte, and the inflow of the charging current of the battery is strictly controlled when the full charge is approached.

For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The embodiment of the application provides a method, a device, an electronic device and a readable storage medium for preventing battery overcharge. The device for preventing the overcharge of the battery can be applied to electronic equipment.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for preventing overcharge of a battery according to an embodiment of the present application.
As shown in fig. 2, the method includes steps S1 through S3.
And step S1, determining the theoretical uncharged capacity when the battery is charged to the preset time.
Specifically, a current sensor is used for sampling charging current when the battery starts to be charged, and a current sampling value is obtained. And when the battery is charged to the preset time, integrating the current sampling value sampled from the time when the battery starts to be charged to the preset time, thereby obtaining the charged capacity of the battery from the time when the battery starts to be charged to the preset time:
wherein C1 is the charged capacity of the battery, t0 is the time of starting charging, t1 is the preset time, I1Sampling a charging current sample value from the charging starting time to a preset time for the battery;
As shown in fig. 3, the theoretical uncharged capacity of the battery at the preset time is obtained by subtracting the charged capacity from the nominal capacity of the battery: C0-C1 ═ C2, where C0 is the nominal capacity of the battery and C2 is the theoretical uncharged capacity of the battery.
As a preferred embodiment, a certain time when the battery is near full charge may be selected as the preset time.
And step S2, acquiring the real-time charging capacity and the real-time voltage of the battery from the preset time to the current time.
Specifically, as shown in fig. 4, the battery continues to be charged, and the current sampling value is integrated in real time from the preset time, and the result of the integration is the real-time charging capacity from the preset time to the current time:
wherein C3 is the real-time charging capacity from the preset time of the battery to the current time, t1 is the preset time, t2 is the current time, I2And sampling a real-time current value for charging the battery from the preset moment to the current moment. And the real-time voltage of the battery is monitored by a voltage sensor.
Step S3, before the real-time voltage of the battery reaches the theoretical charging cut-off voltage, if the real-time charging capacity exceeds the theoretical non-charging capacity, adjusting a current sampling value, a nominal capacity, and a theoretical charging cut-off voltage of the battery.
Before the real-time voltage of the battery reaches the theoretical charging cut-off voltage, when the real-time charging capacity exceeds the theoretical non-charging capacity, namely C3 is greater than C2, the fact that an error occurs between the current sampling value and the actual charging current in the charging process of the battery indicates that the current sampling value of the current sensor during the charging of the battery needs to be adjusted to ensure the accuracy of the current sampling value.
Specifically, the adjustment of the current sampling value includes the following steps: the excess capacity is obtained by subtracting the theoretical non-charge capacity from the real-time charge capacity, and C3-C2 is C4, wherein C4 is the excess capacity of the battery in the current charging process. And then determining a charging time period from a preset time to a charging stopping time, and dividing the charging time period by the exceeding capacity to obtain a compensation value C5 of the current sampling value, wherein the compensation value C5 is the compensation value of the current sampling value, and C4/(t 2-t 1). And finally, performing compensation adjustment on the current sampling value by using the compensation value to obtain the adjusted current sampling value. Therefore, the current sampling value is more accurate during subsequent charging, and the accuracy of charging capacity calculation during charging of the battery is improved.
Specifically, the excess capacity of the battery charged this time is used as the compensation capacity of the battery, so the nominal capacity of the battery is added to the excess capacity to obtain the adjusted nominal capacity of the battery. And then searching a preset comparison table of the battery capacity and the charging cut-off voltage according to the adjusted nominal capacity, and determining the charging cut-off voltage of the battery after adjustment. The adjusted nominal capacity and the adjusted charging cut-off voltage are used as the basis for preventing the overcharge of the battery during the subsequent battery charging. Through the accurate adjustment of the battery capacity and the accurate adjustment of the battery charging cut-off voltage, the accuracy of preventing the battery from being overcharged is ensured, the voltage allowance does not need to be set, and the accurate prevention of the battery from being overcharged can be realized without sacrificing the capacity.
It should be noted that after the current sampling value, the nominal capacity and the theoretical charge cut-off voltage of the battery are adjusted, the adjusted theoretical charge cut-off voltage of the battery is used as the basis for preventing the overcharge of the battery during the subsequent charge of the battery, and the battery is controlled to stop charging after the real-time voltage of the battery reaches the integrated theoretical charge cut-off voltage.
In some embodiments, before the real-time voltage of the battery reaches the theoretical charging cut-off voltage, if the real-time charging capacity does not exceed the theoretical non-charging capacity, which indicates that the current sampling value is accurate and there is no error with the actual value, the battery is controlled to stop charging when the real-time voltage reaches the theoretical charging cut-off voltage.
In some embodiments, the method of the above steps may be repeated every time the battery is charged to prevent the battery from being overcharged, so as to ensure the accuracy of the current sampling value of the battery in every charging, and ensure that the nominal capacity and the theoretical charge cut-off voltage of the battery are dynamically associated with the state of the battery, so that the charge capacity of the battery is in an optimal state, and capacity does not need to be sacrificed to prevent the battery from being overcharged.
By adopting the method in the embodiment of the application, the accuracy of the current sampling value can be improved when the battery is charged, the accuracy of battery capacity estimation is improved, the charging cut-off voltage is calibrated in real time, the overcharge is accurately and effectively prevented, and the effects of protecting the battery, reducing the battery loss and prolonging the service life of the battery can be achieved.
