Discharge Requirements of YUASA UPS Battery

Discharge Requirements of YUASA UPS Battery

YUASA UPS battery is an important external equipment which can provide continuous, stable and uninterrupted power supply. It is a power electronic equipment that integrates digital and analog circuits, automatic control inverters and maintenance-free energy storage devices.

Charging and discharging of UPS batteries are required. Especially in harsh working environment, temperature control is more strict. When the ambient temperature is higher than 25 C, the capacity of UPS batteries is higher than the rated capacity.

When the ambient temperature is lower than 25 C, the battery capacity is lower than the rated capacity. Capacity varies with temperature. Maintenance personnel must conscientiously adjust the discharge current of the battery according to the actual temperature change, and control the temperature of the battery to keep it in the range of 22 ~35 ~C. High temperature service environment is the main reason that the actual life of storage battery can not reach the design life.

The acceptance of charging current under constant voltage doubles with the increase of temperature of UPS battery l0 C, and the life of UPS battery will be shortened by the increase of total cumulative charge. The basic requirement for UPS battery operation and maintenance is that in order to make the battery always fully charged without overcharging, more than 80% of the rated capacity should be released when the battery is supplied to the load alone.

Discharge tester is specially designed for checking discharge experiment, capacity test, battery routine maintenance, engineering acceptance and other DC power load capacity test. The power consumption part of battery discharge tester uses new PTC ceramic resistance as discharge load, which completely avoids red-hot phenomenon. Fully reliable and pollution-free.

The whole machine is controlled by microprocessor, LCD display, Chinese menu.  New appearance design, small size, light weight, easy to move. After setting various discharge parameters, the whole constant current discharge process is automatically completed. Intelligence is fully realized. Make the whole discharge process safer. It is especially suitable for battery acceptance, check discharge test and periodic deep discharge occasions.

As an important part of UPS system, the quality of storage battery is directly related to the reliability of the whole UPS system. No advanced UPS can meet the requirement of uninterrupted power supply if the battery fails. Therefore, the maintenance of Tangshao battery is particularly important in UPS system maintenance
