Battery Current Limit (BCL)

Battery Current Limit automatically limits the battery charge current within a configured range (a percentage of the C10 rating of the battery) by varying the system voltage.

Enable Battery Current Limit to prevent:

Overcharging of the batteries in under-loaded systems

Overgassing of the batteries

BCL Engine Run Limit limits the battery charge current to a preset value, when the power system is powered by a standby engine/alternator during an extended AC power outage. A smaller engine/alternator set can therefore be used without excessively pulling down the alternator voltage.

If BCL Engine Run Limit is enabled, then:

The battery current limit process will use the Engine Run Limit as the charge parameter rather than Battery Current Limit, and

The User Digital Input and User Alarm number (as specified by the Engine Run Digital Input number) will not be available. (The default setting is Digital Input 1.)

Battery Test

Battery Test is a preventative maintenance tool that monitors the discharge capabilities to ensure that the condition of the battery has not deteriorated over time.

The SM45 supervisory module temporarily reduces the output voltage of the rectifiers just below the bus voltage for a set duration. The battery now supplies power to the load. A battery test passes if the battery capacity remains above a predetermined level for the duration of the test.

Battery Test does NOT function during a Fast Charge or Equalize process or during the first 48 hours after an AC power outage.

Equalize

Equalize charges the batteries at a higher voltage after they have been fully charged to ensure that all individual cell voltages are the same.

Battery manufacturers recommend that batteries be equalized periodically. Refer to the battery manufacturer’s instructions, before equalizing the batteries.
