What are the charging methods for UPS battery?

UPS battery charging method UPS constant voltage charging in the later stage of charging, the charging current gradually decreases, compared with other charging methods, closer to the best charging method, there are many other more commonly used charging methods. Important includes UPS constant current charging, constant voltage current limiting charging, UPS fast charging and so on. At this time, the user should choose the most suitable charging method according to actual needs. At present, UPS power supplies use three battery charging methods: constant current charging, constant voltage charging, fast charging 1, constant current charging: constant current charging uses a segmented constant current method for charging. This is generally achieved by adjusting the charging device itself. The charging current can be selected and adjusted arbitrarily, and it is highly adaptable, especially suitable for low-current long-term charging, and also beneficial to the charging of batteries with slower capacity recovery. The disadvantage is that the initial charging current is too small, and the later charging current is too large. The charging time is too long, and there is a lot of gas evolution. It is generally used in the initial charging and desulfurization charging at low current. 2. Constant voltage charging: Constant voltage charging means that each single cell battery is charged with a constant voltage. The characteristics are: the initial charging current is quite large, the battery electromotive force and the relative density of the electrolytic liquid rise rapidly, as the charging continues, the charging current gradually decreases, and only a small current passes at the end of the charging period: short charging time and low energy consumption. Generally, the battery can be charged for 4~5h to obtain 90%~95% of its own capacity; if the charging voltage is selected properly, the entire charging process can be completed in 5h, and the entire charging process does not require human attention. This charging method is widely used for supplementary charging . 3. Fast charging: Fast charging refers to a charging method with a large current method. Fast charging does not produce a large number of bubbles and does not generate heat, which can shorten the charging time. At present, the commonly used fast charging mainly includes pulse charging and high current fast deceleration and fast charging.
