1. The measurement range and accuracy are the same of these for cell voltage.The GPIO readout is done in a time frame

non-overlapping with the readout of Cell voltage.

2. When the GPIO ports are used for temperature measurement, the OV/UV detection can be used for OT/UT (under voltage

→ over-temperature, over voltage → under-temperature).
