Looks like the original design did in fact only have a single temp sensor,
even if they were managing individual cell voltages. Beats me how such a
design ever got past engineering.
Back at the beginning of the thread there was detail about the BMS using a patented system that managed the charging of the cells using software that
predicted the temperatures from the voltage across the cells. It would appear that 'patented' is not the equivalent to validated as working.
What is Thales saying about this?- They provided the entire battery assembly and BMS.
