Tests with Batteries
Set V
to equal battery voltage
f
Connect battery/batteries
Check the correct Battery Capacity (Ahrs) has been entered (SM36 Config.,
"Charge" tab). This is the total capacity, so for 100Ahr string, this should be
100.
Go to SM36 Config, "Control" tab. Set the Battery Charge Current Limit to "Enabled"
(middle right of screen). Also check Battery Current Limit (BCL) is set to desired level
(usually 0.25C
, (25%)). This means that for a single 100Ahr battery, the BCL will be
10
25A, or if two 100Ahr batteries are connected in parallel, the BCL will be 50A.
Go to SM36 Config. "Battery Monitoring" tab. "Tick" Logging Enabled.
Set:
Status Log Sampling Interval to 7 days (provides a "snapshot" of the battery
-
state every 7 days)
Discharge Log Sampling Interval to 1 minute
-
Discharge Log Continuation Time to 5 minutes (this is the length of time
-
logging continues for after AC power is returned)
Connect load (but turn off).
Set V
to 54.0V.
f
Turn on Battery Breaker/s
Check Battery current is positive if charging
For systems fitted with Battery Monitoring
(BCM) cards:
Go to SM36 Config., "Battery Monitoring" tab
and "tick" start scanning.
Check that the all the battery cell voltages are
approximately the same, at about 2.25V (or
13.5V for 12V monoblocs).
If any are out by a large amount, then check
the BCM sense wiring is correct
Set load to required level (e.g., 50A),
Initiate Battery Discharge Test (from SM36
Config., "Charge" tab, click "Battery Test
Enabled")
Check Battery Current is negative
(discharging)
Check Battery Current
After several minutes or until the battery
voltage has dropped below approx. 47V, "un-
tick" (stop) Battery Test (from SM36 Config.,
"Charge" tab). During this time the Battery
Condition Monitor (if fitted) will be logging
every minute.
Battery Current Limit (BCL)
Check that the battery recharge current is
