The battery is an important part of the UPS system, which is directly related to the reliability of the entire UPS system. The battery is part of the shortcoming of the entire UPS system.
The type of battery can generally be divided into lead-acid batteries, lead-acid-free maintenance storage batteries, and nickel-cadmium batteries, considering factors such as load conditions, use environment, life and cost, and cost, UPS generally select valve-controlled lead-acid-free maintenance storage.
The following describes what the main factors affecting the service life of the battery should be paid attention to:
The ambient temperature affects the battery. The impact of discharge depth on battery life is also very large. Battery is stored, transported, and the part capacity is lost due to self-discharge. Battery charging current is typically represented by C, and the actual value of C is related to battery capacity.
Charging voltage. For maintenance-free batteries, due to an absorption electrolyte system, no gas is generated during normal use, but if the user uses improper use, the battery is overcharge, the gas will generate a gas, at which time the battery internal pressure will increase, put the battery The pressure valve is topped, which is severely burst.
UPS is running during operation, pay attention to monitoring the end voltage value of the battery pack, a floating current value, a voltage value of each battery, a battery pack, and a pair of insulating state of the Barbelling busbar. Do not increase or reduce the load of several monomer batteries in the battery pack, which will cause unbalancedness of the cell capacity and the unevenness of charging, reducing the battery life.
The battery should be installed as much as possible in clean, cool, ventilated, dry, and avoid the effects of sunlight, heaters or other radiation heat sources. The battery should be placed correctly and cannot be tilted.
Regular maintenance. Understanding and clearing the main factors affecting the life of lead-acid batteries and matters that should be noted during use, there is a great help of our proper use and maintenance lead-acid batteries in the UPS system. I hope that everyone will properly use and maintain lead-acid batteries in their daily work to make it more reasonable.
