Appendix BBattery ChargingXS Power IntelliCHARGER User GuideAppendix BAppendix B describes battery charging in more detail.The IntelliCHARGER charges batteries in a sequence known as multi-stage charging. The chargingvoltage delivered to the battery depends on the battery’s depth of discharge.The three automatic stages are:• Stage One - Bulk• Stage Two - Absorption/Equalization• Stage Three - FloatBulk ChargeIn the first stage, known as “bulk” charging, the IntelliCHARGER delivers its full-rated outputcurrent. This constant current is delivered to the batteries until the battery voltage approaches itsabsorption voltage, either 2.425V per cell or 2.375V per cell depending on battery type selected.The bulk charge stage restores about 80% of the battery’s charge and this stage completes veryquickly unless the battery is deeply discharged. During this stage the charge rate current on theammeter should read 20A, then cascade to 15A after a 10 min. time period.Absorption/equalize ChargeDuring the second stage, known as “absorption” charging, the charging voltage is held constantnear the gassing voltage, and the charging current is allowed to diminish as the battery comesup to 100% charge. Complex algorithms considering the time, voltage level, and charging currentdetermine when the charger exits this mode and goes to stage three, float charging. The lengthof time of this mode depends on the battery and is not fixed.Float ChargeThe third stage, called “Float” charging is a maintenance mode in which the output voltage ofthe charger is reduced to a lower level, typically about 2.26 V per cell to maintain the battery’scharge without losing electrolyte through gassing. In the float mode, the charger will initiate anew charge cycle if:• AC power is disconnected and reconnected• The current demand on the IntelliCHARGER exceeds the battery recharge current setting.8Figure B-1 Multi-stage charging profileFAQ’sCan I change the clamps on the charger with quick disconnects?Yes. We recommend soldering all electrical connections where possible.Can I run my electric water pump and cooling fan while charging?Yes with a word of caution. There are two issues. First the charger will only provide 20A maximumcharge current. Any amperage being consumed by extra electrical loads (ie. electric water pumps,etc.) will take away from the amperage available for battery charging. The battery charge time willbe increased. In addition, the battery charger monitors the battery voltage and time to determinewhen the battery is at 100% charge. Extra electrical loads on the system will give the chargerfalse information and therefore will prevent the charger from properly completing stage two.Second, some electrical items can be damaged by high voltages. Data loggers, computers, andother items may lose data or be seriously damaged if subjected to the 19.0~20.0VDC of chargingvoltage. We do not recommend retrieving this information while charging. If in doubt about aparticular component, consult with its manufacturer concerning its maximum input voltage.CAUTION: Data loggers, computers of all sorts, and light bulbs may be damaged by the 19.0~20.0VDCof input voltage during charging. Do not operate these items while charging. We recommend disconnectingthe battery from the system while charging.FAQ’s XS Power IntelliCHARGER User GuideFAQ9 |
