13. APPENDIX 1 Measuring The Midpoint Voltage Of A 24V Or 48V Battery Bank Being able to measure the midpoint (or center-) voltage of a battery bank that contains multiple series connected batteries or cells, is an important feature that can save you a lot of money in case one of the batteries or cells is dying. One bad battery or cell can for example show a high internal leakage current, causing an excessive terminal voltage deviation compared to the other batteries in the series string.
Please note that when using the +B2 input for midpoint voltage measurement, you should set Function F2.0 to ‘MIDPNT’. You can also configure the +B3 input for midpoint voltage measurement, but only one of these two inputs can be used at the same time for this purpose. When connecting multiple series strings in parallel to increase the total battery capacity, things are getting slightly more complicated.
The above images are also indicating that busbars are being used to respectively join all positive and all negative battery cables. Besides this, all positive and negative battery cables that are wired to these busbars need to be of equal length. These precautions are made to avoid any imbalance between the different series strings, to ultimately improve the overall accuracy of the midpoint voltage measurement.
Since there are too many variables involved, Enerdrive assumes no responsibility or liability for battery damage or costs which might arise out of the use of the midpoint voltage alarm. This functionality should only be used by experienced installers with sufficient battery knowledge and is intended for global indication purposes only.
