Normally, HS315 performs the "standard" charge cycle. It executes the "Full" charge cycle in
two conditions:
•
If a digital input configured with the function DIF.2321 ("Full charge") is active at the
start of the charge cycle.
•
If the parameter P.9660 ("Number of standard charge cycles to perform one full charge
cycle") is set to a value other than zero, HS315 performs a
“full” charge cycle for every
P.9660 “standard” charge cycle (If P.9660 is set to zero, this function is disabled).
HS315, at the beginning of each charge cycle, records the following events (if enabled with bit
8 of parameter P.0441):
•
EVT.1521
: Start of the “standard” charge cycle.
•
EVT.1522
: Start of the “full” charge cycle.
The second line of the page M.02 displays the current cycle type ("standard" or "full") on the
second row, in REVERSE (only if the charge is in progress).
HS315 uses a three-stage charge process for the battery, that is the most efficient and most
used. The three stages, visible in the following picture, are named:
•
Stage 1: BULK.
•
Stage 2: ABSORBTION.
•
Stage 3: FLOAT.
In this stage, the charge of the battery is made at fixed current.
The current setpoint is provided by P.9675
(“Charge (full) current in BULK mode”) or P.9682
(“Charge (standard) current in BULK mode”) (see 9.5.7). The controller must act on the voltage
regulator (or on the speed governor for permanent magnets alternators) to force the battery
current to be negative (we are charging the battery) and equal to the setpoint.
