I Charger Safety Features
Battery over temperature safety.
I Charger has provision for Lithium battery temperature moni-
toring. This feature monitors battery pack temperature using
the optional temperature sensor. You simply attach an optional
temperature probe to the battery with tape and if the battery
temperature moves outside a safe charging range of 0°C to 40°C
or 104° Fahrenheit , the I Charger suspends charging and signals
a
fault condition (Red LED)
. Once temperature returns to the safe
range then charging will continue.
Battery Bad Detection
I Charger also has bad battery detection, which triggers a
charge
fault (Red LED)
if a battery stays in precondition mode for more
than one eighth (23 minutes) of the total charge cycle time.
Automatic Charger Over Temperature Safety
During the charge process the I Charger monitors each charger
board individually. If the temperature of an individual charge
board reaches a high temperature condition then the charge cur-
rent on that charge board is reduced to maintain a safe operating
temperature range. This applies to each individual charge board.
Step 1
First note that the charge ports (Boards) are numbered from the
top down, so a three port charger will have the top charge port as
number one and the one below that number two and the bottom
one number three.
The LCD screen plate is above the number one charge port. The
LCD displays each battery’s information also from top down and is
indicated as B1, B2, B3 etc.
