Abstract

The method includes following steps: in procedure for charging accumulator in constant electrical current, pulse current is added in good time to carry out discharge; monitoring variety of charging and discharging time values to determine state of charging accumulator; controlling quick pulse charging operation for accumulator based on charging state. Eliminating polarization phenomena quickly and effectively when charging accumulator, the invention increases speed and shortens charging time, and raises charging efficiency. Especially, the invention avoids undercharge from occurring in area, where environment of electric grid is execrable so as to prolong service life of accumulator.

Description

technical field

[0001] The invention relates to the field of accumulators, in particular to a pulse fast charging method and a charging system for an accumulator. Background technique

[0002] With the rapid development of mobile communication scale, there are more and more unattended outdoor base stations. However, in recent years, many operators have generally reported that there are major problems with batteries used in outdoor base stations. Take the commonly used valve-controlled sealed lead-acid VRLA battery as an example. For similar VRLA batteries from the same manufacturer, the service life of the battery for outdoor base stations is much lower than that of the battery for central office stations, which is far lower than the design life of the battery. For example, if the capacity is 2V The average service life of the batteries in the world is less than 3 years, and the average service life of the batteries with a capacity of 12V is less than 1 year. This has cause...
