Embodiment Construction

[0049] The battery charging method of the present invention mainly adopts the battery voltage (the output terminal of the charger and the battery voltage terminal are the same terminal, so the battery voltage here is not the battery voltage in the true sense, it is the voltage of the charger output and the parallel connection of the battery) and Time is used as the basis for judgment, and switching is carried out between each charging stage, so as to meet the requirement of limited power charging, and meet the requirement of charging to 90% of the battery capacity within 3 hours.

[0050] figure 1 It is a flow chart of the normal mode charging method of the battery charging method of the present invention, and the process shown is as follows.

[0051] In step S11, it is first determined whether the battery voltage is greater than or equal to the voltage setting value, if yes, execute step S14, otherwise execute step S12. In an embodiment of the present invention, the voltage ...

Abstract

The invention relates to a battery charging method comprising: charging a battery according to a normal charging mode, wherein the normal charging mode comprises a step 11; judging whether battery voltage is more than or equal to voltage set value; if so, performing a step 14, otherwise performing a step 12; in the step 12, judging whether charging time is less than set protection time; if so, performing a step 13, or performing a step 14; in the step 13, adopting an equalized charging mode to quickly charge the battery, and returning to the step 11; in the step 14, adopting a pulse mode to charge, and performing a step 15; in the step 15, judging whether charging time is less than or equal to a first set period; if so, returning to the step 14, or performing a step 16; in the step 16, adopting low voltage to charge for a first set time; adopting the pulse mode to charge for a second set period; and performing the step 16 circularly. The implementation of the charging method of the invention can quickly charge in short time; and meanwhile, temperature rise in the charging process can be effectively controlled.

Description

technical field [0001] The present invention relates to rechargeable batteries, and more particularly, to a battery charging method. Background technique [0002] Due to the advantages of mature technology, low cost, large battery capacity, good output characteristics following the load, and no memory effect, lead-acid batteries are widely used in various power systems as energy transfer or backup power. However, due to the limitations of various technical conditions, the charging methods used cannot follow the physical and chemical laws inside the battery, so that there are serious overcharging and gassing phenomena in the entire charging process, and the charging efficiency is low. In other words, the vast majority of batteries are not used up, but charged. [0003] Existing charging methods usually include slow charging with low current, constant current and constant voltage charging, and segmented charging. If the charging time is too long, it will not only prolong the...
