Thanks for your answer Bub

ln theory this information is available on the OBD socket, the fact is that I don't know of a dedicated app that makes these measurements.
To tell the truth I can connect with the EvBat Mon App by setting Mitsubishi imiev as vehicle, but the voltages and temperatures of the individual cells are out of order.
There is also the possibility to customize the PIDs and create a tool for each cell, but I don't know where to find them ... Here I assume we need an expert ...
Help!! I am willing to pay a hefty fee to those who help me ... Thanks
