FAQ: What is the RT-BMS consumption during stand-by and the operation?
The total energy consumption of the RT-BMS Master unit (from the 12V board battery) in the stand-by mode is about 5mA. During the operation it is 100 mA and more for each CBU module (about 5mA for each CBU module). The consumption of a setup with 32 cells may have a consumption of 100mA + (32 x 5mA) = 260 mA.
Tip: If your BMS consumption is significantly higher, your should check your setup, as there may be some problem.
The energy consumption of the CBU modules is taken from the cells themselves. It is about 0.1 mA in a standby mode and 30 mA in operation mode.
Warning: Please keep in mind that especially with small capacity cells, the cells may be depleted by the CBU modules if left without charging for many weeks. If you have a system that will be left uncharged for long periods of time, we strongly suggest to disconnect the CBU cells (or any other electronics) from the cells.
