To assess and evaluate the capacity and performance of the battery.
To ensure the battery meets the expected operational requirements.
Through capacity testing, accurately grasp the State of Health (SOH) of the battery string and identify poorly performing batteries.
To enhance the overall health of the string battery.
To ensure the reliability and effectiveness of backup power.
When working with low-voltage live equipment, use insulated electrical tools to prevent electric shock.
Properly label battery terminals and ensure correct wiring to avoid short circuits.
Strictly prohibit direct current (DC) short circuits and grounding.
Maintain a safe distance and implement isolation measures from live equipment.
Manual capacity testing imposes high demands on personnel. The capacity testing process is not conducive to the operational safety and reliability of the equipment. The long operating time and the large number of equipment make it difficult to ensure that the routine capacity testing is completed in accordance with the specifications.
For example, one power supply bureau oversees 62 substations of various voltage levels, all of which are equipped with dual DC systems, meaning a total of 124 battery strings are in use. According to comprehensive statistics, 66 of these strings have been in operation for more than five years, and 58 for less than five years. This indicates that on average, 95 battery strings require capacity discharge testing each year. If two groups of personnel perform capacity discharge testing each week, it would take six months to complete.
The remote online capacity testing system for battery sets can safely and reliably conduct remote discharge capacity tests, enabling early detection of poorly performing batteries. It can also provide continuous current to batteries with open-circuit faults during operation, thereby automating and intelligently managing battery maintenance tasks.
DFUN developed remote online capacity testing solution for Telecom Power Systems integrates multiple functions, including remote capacity testing, energy-efficient discharge, intelligent charging, battery monitoring, and battery activation. This solution effectively addresses the challenges of manual inspections that are time-consuming and labor-intensive, the difficulty of offline capacity testing due to disconnection and reconnection issues, and the challenge of maintaining dispersed sites. It is suitable for systems such as substations, control centers, and energy storage power plants.
