Abstract

The invention provides a variable-current charging method of a storage battery. The method comprises a constant-flow charging stage, a pulse quick charging stage and an additional charging stage. In the constant-flow charging stage, the storage battery is subjected to constant-flow charging by first charging current until a voltage value of the storage battery reaches a first preset voltage value; in the pulse quick charging stage, the storage battery is subjected to cyclic pulse quick charging in a manner of alternating positive pulse charging and negative pulse charging; when one cyclic pulse quick charging period is ended, a positive pulse current value and a negative pulse current value are reduced; meanwhile, the charging time and the discharging time are shortened; the next cyclic pulse quick charging period is carried out until the positive pulse current value reaches a second charging current value; and in the additional charging stage, the storage battery is subjected to additional charging in a constant-voltage charging manner. Through the variable-current charging method, quickly and efficiently charging a large-capacity storage battery can be achieved; the polarization phenomenon is removed; and the damages to the storage battery are reduced.

Description

technical field [0001] The invention relates to the technical field of storage battery charging, and more specifically, relates to a variable current charging method for a storage battery. Background technique [0002] Large-capacity batteries are one of the important components of marine electrical equipment. They are not only used as starting power for diesel engines on ships, but also need to provide electrical energy for ship communication, navigation and other equipment and emergency lighting. At present, the constant current charging method is used to charge the large-capacity battery of the ship. Constant current charging refers to the charging that the current is maintained at a constant value. The constant current charging method is to keep the charging current constant by adjusting the output voltage of the charger or changing the resistance connected in series with the battery. [0003] However, the so-called constant current charging can only maintain a constant...
