Embodiment Construction

[0020] This embodiment proposes a pulse charging method that can prolong the service life of the VRLA battery used for communication power. Such as Figure 4 As shown, this method divides the charging process into three sections A, B, and C, wherein section A is charged with a constant current of the charging current limiting current I; section B is charged with a constant current of the current limiting current I and a constant voltage cycle of the second charging voltage U2 Charging with periodic changes; Section C is charged with periodic changes in the constant voltage of the first charging voltage U1 and the constant voltage of the second charging voltage U2. in press image 3 When the charging voltage-time curve is set, the battery capacity in section A starts to charge from close to 0, and the battery voltage gradually increases. When the voltage rises to U1, it transfers to section B; in section B, constant current and constant voltage are alternately charged until th...

Abstract

The invention relates to a pulse charging method used for prolonging VRLA battery service life. The invention aims at provides a pulse charging method used for prolonging VRLA battery service life, such that the service life of a valve-regulated lead acid battery is prolonged. The invention adopts a technical scheme that, a VRLA battery has an output voltage of U and a capacity of C. The method is characterized in that the method is preceded in three sections which are a section A, a section B, and a section C. In the section A, constant-current charging is carried out with a charging limited current I. In the section B, periodic-change charging is carried out with constant current of the limited current I and constant-voltage of a second charging voltage U2. In the section C, periodic-change charging is carried out with constant-voltage of a first charging voltage U1 and constant-voltage of the charging voltage U2. In the section A, when a voltage is increased to U1, the process turns to the section B. In the section B, when the battery is charged to almost full, the process turns to the section C. The invention is suitable to be used in a field of storage battery charger.

Description

technical field [0001] The invention relates to a charging method for a charging power source of a valve-regulated lead-acid battery for communication, in particular to a charging method for prolonging the service life of a valve-regulated lead-acid battery. Applicable to the field of battery chargers. Background technique [0002] In the field of communication power supply, the design life of VRLA batteries can reach 5 to 10 years, and some can even reach 10 to 15 years. However, in the actual use process, the products of most manufacturers have early failure phenomena during use, and some of them will not be able to discharge electricity within 3 years or even less than 3 years. Especially in the use of outdoor base stations for mobile communications, most of them fail after only 1 to 2 years of use. There are problems of heavy maintenance workload and high maintenance costs, which have a serious impact on the normal progress of communications. [0003] The charging mode...
