BLU A Series - DV Power Battery Load Capacity Tester

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 500 V battery voltage. As a special feature, the BLU100L model enables the capacity testing of a single Li-Ion cell. Additionally, when combined with Zero Voltage Discharge Module ZVD80, BLU-A enables full battery discharge down to 0 V with up to 60 A, required before battery recycling.

An overview of the maximum discharge current for BLU-A models for various battery voltage levels can be found in the table below.

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 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, the BLU 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.
