Operators Manual
2.1.1
Charging Modes
CONSTANT VOLTAGE CHARGE
Where the battery is charged at a reducing current when the constant voltage
threshold is met. Parameters for this mode are maximum charge time, optional
minimum current to stop charge and a current threshold, which can detect a
potentially faulty battery.
CONSTANT CURRENT CHARGE WITH TOP UP CHARGE
Where battery is charged at a constant current until a terminal voltage is met or
a specified maximum time, at this point it can be charged for an additional time
at a user set current. The overcharge voltage is set in this mode to prevent
overcharging of the battery.
MULTIPLE STEP CONSTANT CURRENT CHARGE
Up to 4 constant current steps can be implemented for the charge cycle. this
mode also has an overcharge voltage setting to prevent overcharging of the
battery. Charge current can be set to zero for “rest” periods between charge
steps.
CONSTANT CURRENT USING CELL MONITOR
In this mode the battery will be charged at constant current with the charge
switching to the top up charge (if required) when all the cells reach the target
voltage specified or a maximum time. A cell overcharge voltage can be set once
the top up charge has been activated, and during the whole charge a fall in cell
voltage can be detected an indication of cell breakdown.
2.1.2
Capacity Testing Modes
CAPACITY TEST TO TIME
This mode will discharge the battery connected at the current specified for the
test duration specified thus reporting the battery capacity is 100% or more. The
capacity test will be stopped if the target voltage is reached before the full test
time has elapsed. During the capacity test and when it is terminated the display
will show the amount the capacity test is complete as a percentage.
CAPACITY TEST TO TARGET VOLTAGE
This mode will discharge the battery down to the terminal voltage specified thus
reporting the actual percentage capacity. The capacity test will be stopped if the
target threshold voltage is reached before the full test time has elapsed. During
the capacity test and when it is terminated the display will show the amount the
capacity test is complete as a percentage.
CAPACITY TEST WITH CELL MONITOR
This mode will discharge the battery connected at the current specified for the
test duration specified thus reporting the battery capacity is 100% or more. The
capacity test will be stopped if any cell reached the cell target voltage before the
full test time has elapsed. During the capacity test and when it is terminated the
display will show the amount the capacity test is complete as a percentage.
