BT-Lab Technical Note 49: Measurements with BCS-800 & BT-Lab® software starting from a negative Ecell value

Secondary batteries require testing during the different stages of their development process.

During the evaluation of self-assembled cells, sometimes their initial overpotential floats around -200 mV after the first assembly. When working with BCS-800 systems, two validations are necessary when trying to begin a technique with a battery whose initial potential is negative:

– hardware detection: handled locally and results in the inability to start the control in the experiment.

– software detection: results in an error message and the blocking of the technique by the software

This note introduces the procedure to be followed with BT-Lab^® 1.73 version (and higher), which will allow the technique to continue once negative potential values are reached, even if error messages are displayed.
