Figure 7 Second-time power voltage-limiting module
5 .Battery temperature switchover module
The temperature’s measure is finished on TTPU veneer, and the battery’s ID measure is finished on
PIPU veneer.
This module converts the thermistor into voltage and sends the voltage to ADC on the TCPU board
to be measured. Thus, the battery temperature will be measured.
See the following figure for the circuit.
