Method for charging battery of fusion splicer

Abstract

The invention discloses a method for charging a battery of a fusion splicer, which successively comprises the following steps: constituting a charging circuit composed of an LTC4002 current charging board and a DC-DC step-down conversion module, and connecting the charging circuit to a power source; constituting a power supply circuit by a DC-DC conversion module; successively connecting the powersource with the DC-DC step-down conversion module and the LTC4002 current charging board by connection terminals and then with a lithium battery; and successively connecting the lithium battery, theDC-DC step-down conversion module and an output terminal. The method solves the problem of a DC standby power supply in the prior art. The charging circuit can be charged by a variety of power sources, such as 220V AC, onboard 12V DC, and solar power. The battery of the fusion splicer is connected to the solar charging board to be passively charged, which solves the problem that the fusion splicercannot be charged when used outdoors for a long time, and light and environment-friendly requirements are satisfied.

Description

technical field [0001] The invention relates to a storage battery, in particular to a charging method for the storage battery of a fusion splicer. Background technique [0002] At present, various industries in China use optical fiber fusion splicers to work in the field. In many cases, the power supply of the equipment itself cannot meet the needs. The main reason is that the battery capacity is too small to work for a long time. In this regard, most units bring lead-acid batteries or small gasoline generators to the site. These two types of power sources are DC backup power sources known for their bulkiness. Especially in mountainous areas, it is very inconvenient to use and requires a lot of manpower and material resources to carry them ,very inconvenient. Lead-acid batteries have serious self-discharge, and small gasoline generators sometimes cannot work well due to factors such as gasoline engine oil. Contents of the invention [0003] The present invention solves t...

Problems solved by technology

[0003] The present invention solves the problem of inconvenient use of DC backup power in the prior art, especially in mountainous areas, and requires a large amount of manpower and material resources to carry it, which is very inconvenient. A new type of lithium battery that is not easy to explode is adopted, which has the characteristics of small size, light weight, large capacity, small internal resistance and good discharge characteristics.

The battery of the fusion splicer is connected to the solar charging board for passive charging, which solves the problem of no power supply for the fusion splicer for long-term field operations, and meets the requirements of portability and environmental protection
