Description
Technical Field
The present invention relates to the field of battery management technologies, and in particular, to a battery charging method and a computer-readable storage medium for reducing charging time and damage to a battery during charging.
Background
With the market demand for new energy vehicles, energy storage and 3C electronic products becoming higher and higher, the battery charging speed is receiving much attention. The proper charging method can reduce the charging time, prevent the battery from being overcharged and reduce the damage of charging to the battery.
The main charging method at the present stage is a CC (Constant Current) -CV (Constant Voltage) charging method, and when the remaining battery capacity is in a low interval, the CC charging method is adopted to charge, so that the charging time is shortened by increasing the charging Current. And after the residual electric quantity of the battery reaches a high interval, charging in a CV mode, setting the constant voltage of the charging equipment, and gradually reducing the charging current of the battery until the voltage of the battery reaches the set voltage. However, in order to reduce the CV charging time, a minimum limit needs to be set for the charging current, and thus, the charging time is long and overcharging is likely to occur due to the setting of the charging current lower limit method.
For example, a chinese patent document discloses "a super capacitor constant current charging method based on phase control and a charging device thereof", which is disclosed in CN109888868A, wherein each charging control module is used to make the output current values of all charging modules the same by obtaining the current data, performing coordinated current control on the local charging module corresponding to the output current values of the local charging module and each adjacent charging module connected in parallel with the local charging module, and performing phase control on the corresponding local charging module according to the phase difference between the front and rear charging modules and the local charging module. Although the scheme performs the cooperative current control and the phase control of the corresponding charging module to achieve the effect of improving the reliability of the charging system, if the maximum current charging is continuously kept, the charging time is shortened, the protection of the equipment cannot be taken into consideration, and the overcharge easily occurs, if the minimum current charging is kept, the charging time is increased, and the constant current value is set by using the constant current charging method, so that the charging time is long, the equipment is easily damaged due to the overcharge, and the functions of shortening the charging time and preventing the overcharge cannot be achieved at the same time.
