8.1.2 Adjusting the Charge Efﬁ ciency Setting

The Charge Efﬁ ciency setting determines how the battery monitor calculates

the battery’s charge efﬁ ciency. The charge efﬁ ciency can be calculated

automatically using the Auto setting, or can be manually programmed by

the user (see Figure 8-2).

The battery monitor is shipped with the charge efﬁ ciency set to Auto. This

allows the battery monitor to automatically calculate variables that affect the

charging efﬁ ciency—such as battery type, battery age, and how the batteries

are maintained—which is not always constant. With the Auto setting, the

efﬁ ciency is recalculated each time the batteries reach a 100% SOC.

This setting can also be manually adjusted from 50% to 97% to calculate the

AH I/O reading—if the battery’s charge efﬁ ciency is known. For example, if

you set the charge efﬁ ciency to 90%, and 100 AHrs are removed from the

battery, the AH I/O display would read 000 only after 111 AHrs have been

returned to the battery.

Figure 8-2, Adjusting the Charge Efﬁ ciency Setting

If the charge efﬁ ciency is manually set and inaccurate, the SOC information

will be more inaccurate with every charge. For this reason, continually

monitor the AH I/O display under the remote’s METER button.

To access the AH I/O display: press the METER button, turn the SELECT

knob until the 03 BM: Meters menu appears, press the SELECT knob again,

and then turn the SELECT knob to the AH I/O display.

After several charge/discharge cycles (below 80% SOC), the AH I/O reading

should be slightly positive when the 02 BM: SOC Batt SOC display reads 99%.

To view the Batt SOC display: press the METER button, turn the SELECT

knob until the 02 BM: SOC menu appears. If the AH I/O reading is below 000

(negative#) when the Batt SOC display reads 99%, then increase the charge

efﬁ ciency setting. If you ﬁ nd that the AH I/O reading is substantially above

zero when Batt SOC reads 99%, then decrease the charge efﬁ ciency setting.

8.2 Adjusting the Batt AmpHrs Setting

It is important that the METER button’s 05 BM: Setup menu’s Batt Amphrs

setting is correct or else the calculations used to determine the 02 BM: SOC

display will be inaccurate.

To access the Batt AmpHrs setting: Press the METER button on the ME-

RC, and then rotate the SELECT knob until the display shows the 05 BM:

Setup menu. When the 05 BM: Setup menu appears, press the SELECT knob

to display the BM Charge Eff menu item. Turn the SELECT knob until the BM

Amp Hours menu appears. Press the SELECT knob to display the current

Batt Amphr setting. Turn the SELECT knob to adjust the Batt AmpHr setting.

Press the SELECT knob to select and save the new setting.
