2.6 Voltage measurement and undervoltage
Attention: Make sure not to create a short circuit!
-
You can see the max. and min. cell voltage in the BeConnect App.
-
You can get the detailed module and cell voltage in the BCP Program (section 2.5)
-
or measure it manually according to the below description:
Measure the module voltage: Open the front door and measure the tower voltage between B+/B- (red circle).
Measure also between P+/P- (green circle) on the BMS as shown below.
Measure the cell voltages in case of BMS EC 107, EC 103, or if BCP shows cells with <1.5 V / does not show cell
voltages. This will help us to understand if the issue is in the cell or in the BICs.
The voltage has to be measured in pairs as shown below. If the voltage is 0, in most cases this value is not
correct and the measuring device is not in correct contact with the PINs. (please establish a correct and good
contact)
Please record these measurements of 16 cells in total. (Cell Number 1-8 for button module, 9-16 for upper
module)
