I don't understand, i see all the 88 volt and 66 temp sensor data in CAN frame, your car is sure to be 80 cell?
Yes, it's a 80 cell car.. I have 363 hours 7 minutes 38 seconds of logs Max volt:
select max(b_volt) from SECLOG ; 329.7
Cell volt of one missing cell:
select avg(CMU_12_CELL_D) from CELL_VOLTS; 0.000539636363636364 sqlite> select avg(CMU_01_CELL_D) from CELL_VOLTS; 3.89978060606068
The car shuts down if i cell gets down to -30
select count(*) from cell_temps where CMU_12_UNIT_3 > -30 ; 115 select count(*) from cell_temps where CMU_12_UNIT_3 < -30 ; 20510
the 115 readings is odd, seams to be some ghost readings...
select distinct(CMU_12_UNIT_3) from cell_temps ; -50 0 20
Maybe a glitch when starting the car, an initial value.. Since it's only 0 and 20°C, that's likely considering we also see the same with the QC signal of RR=255. Solution? It's likely that the the messages are sent on the bus, but it's not used by the components. We do know, from documentation from Mitsubishi that if the battery (one cell) is below -30°C, the car goes in to hibernation, and wakes up after 6 hours to check if the battery have warmed up. In other words, if one of the sensors is below -30°C of the optional battery cells, then we know that the battery has 80 cells. -- Michael Menk
