What are the charging methods for UPS lead-acid batteries?

UPS lead-acid battery charging method 1. Constant current charging method The constant current charging method is a method of adjusting the output voltage of the charging device or changing the series resistance of the UPS battery to keep the charging current intensity constant. The control method is simple, but because the acceptable current capacity of the UPS battery gradually decreases with the progress of the charging process, in the later stage of the charging, the charging current is mostly used for electrolysis of water, and gas appears, which makes the gas out too much. Therefore, the stage charging method is often used. . 2. Stage charging method The two stage method adopts a fast charging method that combines constant current and constant voltage. First, charge with constant current to a predetermined voltage value, and then change to constant voltage to complete the remaining charging. Generally, the switching voltage between the two stages is the constant voltage of the second stage. The three-stage charging method uses constant current charging at the beginning and end of charging, and uses constant voltage charging in the middle. When the current decays to a predetermined value, the second stage is switched to the third stage. This method can minimize the amount of air outflow, but as a fast charging method, it is subject to certain restrictions. UPS power battery installation site requirements 1. The equipment installation site should be a level hard ground. If it is an anti-static raised floor, the bearing capacity of the floor should be considered, and the steel bracket should be designed and manufactured according to the weight of the equipment. The site should be able to get all necessary services, especially good ventilation with light and electric charge. 2. The UPS power storage battery site should be free of dust, especially conductive dust, otherwise it may cause a short circuit within the equipment and affect the reliable operation of the UPSCGB battery. At the same time, the site should not have or be near a heat source to ensure the environment specified by the equipment.
