The battery capacity test is performed to determine the health of a battery. DV Power’s battery load unit BLU-A is a portable, powerful and lightweight solution for battery capacity measurement. It is applicable to any battery string such as lead-acid, Li-Ion, Ni-Cd, etc., with up to 300V battery voltage. As a special feature, the BLU100L model enables capacity testing of a single Li-Ion cell.
The capacity test is performed in an accurate and user-friendly way. Also, it is in accordance with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.
Battery load unit BLU-A enables setting discharge currents up to 240 A, with a resolution 0,1 A. Furthermore, if higher currents are required, BLU-A units can be connected in parallel, or additional BXL-A load units can be used.
The instrument offers the best power-to-weight ratio in the market. BLU-A models start from 12,8 kg / 28.2 lbs and deliver up to 28,4 kW of power.
The user can select three discharge modes: Constant current, Constant power, Constant resistance. Additionally, different battery duty cycles can be simulated using user-selectable discharge profiles.
The instrument monitors discharge parameters in real-time during the capacity test. A 4,3-inch touch screen display shows battery voltage, current, elapsed time and capacity during the entire test. Also, BLU-A battery load unit can be used with DV-B Win software. As a result of that, a user can see a detailed numerical and graphical presentation of key parameters and can create reports in various formats.
Testing with BLU-A doesn’t require disconnection of the battery from the testing equipment.
Overview of the maximal currents for BLU-A models (BLU100A, BLU200A, BLU340A) for various battery voltage ranges can be found in the brochure for BLU-A series.
