other) with voltages up to 800 V DC.
The BLU-C capacity tester simplifies battery testing in multiple ways. The instrument provides monitoring of discharge parameters (graphical and numerical) on 7 inch touch screen display. Parameters such as battery voltage, capacity, test current / power /resistance and elapsed time can be monitored in real time. As an addition, the instrument enables measurement and monitoring of cell parameters (voltage/intercell voltage/temperature), which makes it a complete stand-alone discharge test system. The capacity tester can also be used with DV-B Win software, enabling detailed numerical and graphical presentation of key parameters, including report creating in various formats.
Using the BLU-C device, the capacity test is performed in an accurate, user-friendly way in
accordance to actual standards for battery testing (IEEE 450-2010 / 1188-2005 / 1106-2015, IEC 60896-11/22 and other relevant standards).
Discharging can be performed at constant current, constant power, constant resistance or in accordance with a pre-selected load profile. If battery needs to supply its load continuously,the discharge test can be conducted by measuring and taking into account the load current during the test.
The BLU-C provides the discharge current of up to 220 A and is applicable to up to 800 V battery voltages.
When a required discharge current or power exceeds the capacity of a single BLU-C device, several BLU-C devices can be connected in parallel. Alternatively, External Load Units BXL Series can also be used to increase discharging capacity. Overview of the maximum currents for various battery voltage ranges with the minimum achievable cell voltage of 1,75 V is presented in tables below.
