Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The main solution of the embodiment of the present invention is to periodically detect the battery internal resistance of the battery. The battery internal resistance is calculated according to the detected voltage and current of the battery. The amount of change between the internal resistance of the battery, and the charging current of the battery is adjusted according to the amount of change.

[0045] Because in the prior art, when using the charger to charge the battery, it usually only reduces the charging current based on the experience of the user when reducing the heat generation of the battery, but when reducing the charging current by virtue of the user experience, if the current reduction If the magnitude is too small, the change of the battery heat generation is small, and it is difficult to reduce ...

Abstract

The invention discloses a battery charger and a charging control method thereof, and a computer readable storage medium, and the charging control method comprises the steps: periodically detecting the internal resistance of a battery, and calculating the internal resistance of the battery according to the detection voltage and detection current of the battery; obtaining the variable quantity between the battery internal resistance detected in the current charging period and the battery internal resistance detected in the previous charging period, and adjusting the charging current of the battery according to the variable quantity. According to the charging control method provided by the invention, the heat generated by the battery is mainly influenced by the internal resistance of the battery, so that the charging current can be adjusted according to the variation of the internal resistance of the battery, the charging current can be accurately determined, and the charging time of the battery is not too long; meanwhile, the calorific value of the battery is within the bearable range of the battery, so the charging time and the calorific value of the battery are well balanced; meanwhile, the charging current of the battery can be adjusted in real time, and the charging time and the heating value of the battery can be better balanced.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a battery charger, a charging control method thereof, and a computer-readable storage medium. Background technique [0002] Ni-MH batteries have not been around for a very long time. In 1989, the first commercial Ni-MH batteries came out under the sponsorship of Daimler-Benz and Volkswagen. The density has been significantly improved, and there is no "memory effect", and it has been widely used in various digital electronic products as soon as it came out. In recent years, with the maturity of lithium battery technology, the market of nickel-metal hydride batteries has gradually shrunk. However, compared with lithium batteries, nickel-hydrogen batteries are safer, less prone to spontaneous combustion, and have a smoother discharge curve. Therefore, nickel-metal hydride batteries still have considerable potential. market share. [0003] Currently, the chargers on the market are...
