Battery Capacity Testing; Start Battery Charging - Power Science CF-3K-12 Series User Manual

CF(M)-3K-12 SUPERCOMBI USER'S GUIDE
voltage of the DC port of the SuperCombi is higher than the actual voltage of
the battery poles during charging, which results in a longer charging time;
Otherwise, the voltage of the DC-side port of the SuperCombi is lower than the
actual battery poles voltage during inverting, causing the battery to stop
discharging before it reaches the discharge cutoff voltage. General Speaking,
the charging time is prolonged since the effect, and the capacity of the battery
cannot be fully utilized during discharge either.
If the "Line Loss Compensation" function is selected, the actual battery voltage
can be sensed by the SuperCombi by installing the remote voltage detection
device attached to the SuperCombi to compensate for the voltage drop on the
battery connection line, and increase the available capacity of batteries based
on safety. This function is particularly significant for the scenario when the
battery cable is long. For details of the optional function, see section '2.2
Device Interface'.

6.7 Battery Capacity Testing

Under the premise of using the function of Charge Pro and Wire
Compensation, the SuperCombi can calculate the SOC very accurately. No
Coulomb meter is needed.

6.8 Start Battery Charging

In order to cope with the inability to start the engine due to the overdrawn of
the starter battery in the front car, the SuperCombi has a "2A start-up battery
charging port" to charge the starter battery. If the customer chooses this
feature, the SuperCombi can be connected to the starter battery through a
cable and keep the starter battery being full to avoid die battery. For details on
the optional function, see section '1.2 Model Definition'.
