4.12.8 Reduced Rate Charge Feature Configuration
The charger can be configured to allow a window of time per day to reduce the charge rate to
the connected battery. This is useful if there is a period of time when the batteries left on the
charger should charge at a slower rate to prevent heating issues. At certain installations the
batteries are opportunity charged at their maximum rate but at a cost of heat generated in the
battery. If it is known that during certain periods the battery will not need to charge at maximum
rate then the power delivered can be backed off by a programmable amount.
When this feature is enabled and the start and stop times are encountered, the maximum
charge rate of the battery is limited to the charge rate programmed in this feature. For example,
if a battery is connected to the charger at 11:00am, the battery capacity is 1000 amp hours, and
its start rate is 50amps/100 amp-hours, the battery will normally start charging at 500amps. If
the reduced rate feature is set to be enabled from 10:00am to 12:00pm, and the limit is
25amps/100 amp-hours, then as soon as the clock reaches 10:00 am, the current will drop from
500 to 250amps. The charging will continue with this rate limit until the window is closed at
12:00pm when the current limit returns to 500 amps.
