2) Voltage Check (with load)

1

Push the load switch to ON (to arrow

direction) direction for less than 5 seconds.

1.

Read the measurement.

2.

Specified

value

7 ~ 9V (Red): Over discharged

or faulty

9 ~ 11V (Yellow): Charging

required

11 ~ 13V: Normal

To identify the battery capacity with the

voltage drop (V) value, discharge the fixed

load capacity (120A) for a certain period (5

seconds).

Operation

▶

EEM monitors the electric loads and battery conditions and controls the voltage to improve the fuel

economy and battery charging efficiency.
EBS on “-“ terminal of battery sends the battery information (voltage, current, temperature and

SOC) to engine ECU with LIN communication.

Engine ECU outputs the information from EBS and regulating control signal (PWM) according to the
engine load conditions to “L” terminal on alternator.

Engine ECU controls the magnetic resistance between stator coil and rotor coil by controlling the

current in rotor coil according to PWM duty value.

The alternating voltage induced to stator coil is converted to direct voltage by rectifier. And, EBS
outputs the charging voltage to “B” terminal on alternator.
