The Battery Load Bank is a special instrument designed for testing NiCD and Lead-acid storage battery strings with overall string voltages of 24V, 48V, 110V, and 220V in communication rooms, and individual cell voltages of 1.2V, 2V, 6V, and 12V. Adopting advanced testing technology, it incorporates breakthrough applications of new techniques, materials, and components. Engineered in compliance with national regulations for stationary battery maintenance, it features large discharge power, compact volume, light weight, and a complete data management software suite for the upper computer to significantly reduce daily maintenance workloads.
When the battery string undergoes on-line discharge, uniform charge, or floating charge, the instrument performs real-time monitoring of the string and individual cells. Tracked parameters include whole string voltage, cell voltage, charge/discharge current, string charge/discharge capacity, and cumulative monitoring time.
Performs constant current discharge using an intellectualized dummy load after the battery string is isolated from the system. Users can set parameters including discharge current, discharge time, discharge capacity, final protective voltage of the whole string, and final protective voltage of individual cells. The tester displays real-time discharge parameters and will automatically stop testing when setup thresholds are met, or when manual termination is triggered.
The tester automatically terminates the test when abnormalities in the battery string, individual cells, or the tester's internal systems are detected, ensuring complete safety during the testing process. The integrated design combines the monitoring and power sections, utilizing high-efficiency components to deliver a compact yet powerful testing system.
