Analysis of Battery Charging Method of Shante UPS Power Supply

1. Constant current charging: Constant current charging uses segmented constant current 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. 2. Constant voltage charging: Constant voltage charging means that each single-cell battery is charged with a constant voltage (usually the single-cell battery is multiplied by 2.5V). The characteristics are: the initial charging current is quite large, the electromotive force of the battery and the relative density of the electrolytic liquid rise rapidly. As the charging continues, the charging current gradually decreases. At the end of the charging period, only a small current passes: short charging time and low energy consumption. 3. Fast charging: Fast charging refers to a charging method with a large current method. Fast charging does not produce a lot 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. 4. Equalization charging: Equalization charging is a 1~3h charging process with a small current (1/20C20A). It is important to eliminate the difference between a set of floating charge operation (that is, the working method of connecting DC power and batteries in parallel) under the same operating conditions, due to the imbalance of the whole set of batteries caused by some reason, in order to achieve the full set of batteries Balance. 5. Constant voltage and current-limiting charging: Constant voltage and current-limiting charging is mainly used to remedy the shortcomings of excessive charging current during constant voltage charging (the method is the same as that of constant voltage charging), by connecting a resistor in series between the charging power supply and the battery to be charged (limiting Current resistance) to automatically adjust the charging current. 6. Smart charging: Smart charging is currently a more advanced charging method. The principle is to dynamically track the acceptable charging current of the battery during the entire charging process. Using du/dt technology, that is, the charging power supply automatically determines the charging process parameters according to the state of the battery, so that the charging current is kept near the acceptable charging battery curve of the battery from beginning to end, and the battery is charged in a state where there is almost no gas, thereby protecting the UPS battery . This article gives several ways to extend the working life of UPS batteries. In general, it can be summarized in four sentences: suitable temperature, regular charging and discharging, good use of communication functions, and timely replacement of damaged batteries. In the study of UPS power supply, there are no university or elementary school questions. As long as you pay attention to observation, you can summarize various characteristics and methods to facilitate our design.
