Vehicles have many control units that use more electricity.
These units control their own system based on information from various
sensors. It is important to provide a stable power supply as these
sensors bring diverse information. Battery sensor is mounted on battery
(-) terminal. It transmits battery voltage, current, temperature
information to ECM. ECM controls generating voltage by duty cycle based
on these signals.
