Photos are not just a static picture, they are a vivid story, is the expression of our love and focus on the battery monitoring industry。Relat engineers keep commissioning battery monitoring products for new projects, and this time escort the mobile ring centralized monitoring system project for the communication room of the complex building of the third grade hospital。
Due to the production process, transportation and installation, daily maintenance and other problems，many batteries have only half the life of the manufacturer's design life, and some even lag behind the battery in 1 or 2 years，correct testing and maintenance is the fundamental solution to the problem.
Due to the complexity and particularity of the hospital, how to ensure that the backup power supply is always in the best condition? What can we do?
1/Scheduled maintenance
Periodically check whether the surface of the UPS battery is dry, dust, and pollutants, and check whether the battery is undercharged, overcharged, and overdischarged to reduce faults caused by abnormal charging and discharging.
2/Standardize charge and discharge management
The floating charge voltage and discharge voltage in the UPS power supply have been adjusted to the rated value at the factory, and the size of the discharge current is increased with the increase of the load, in general, the load should not exceed 60% of the rated load of the UPS. In this range, the discharge current of the battery will not show excessive discharge. Batteries that are not used for a long time should be replenished in time to make the battery fully charged as far as possible.
3/Enhanced temperature control
The battery can have a long life at 20-25 ° C. When the temperature rises, the battery plate corrosion will be intensified, and more water will be consumed, thus shortening the battery life, When the temperature is above 25 ° C, the life of the battery is shortened by half for every 10 ° C increase in temperature, and there is a risk of thermal runaway above 40 ° C. Users should pay attention to the ventilation, heat dissipation and temperature control of the battery room.
4/Take advantage of battery monitoring technology
Battery packs are often composed of a large number of single batteries, and the performance of individual batteries is reduced and the capacity is not up to the requirements, In the continuous operation and use of UPS is inevitable, if not timely detection, find out the aging battery to adjust, will affect the efficient and safe operation of the entire power supply system.
The battery monitoring system can reveal the battery performance characteristics and aging trend to the maintenance personnel in a timely manner, and can accurately evaluate the health status of the battery, obtain the effective basis for battery replacement and cascade utilization, and ensure that the battery can be put into work at any time by replacing the backward battery.
