Therefore, store mode will charge or discharge your pack to around a 60% charged
state to help extend the life of your packs.
CUT.TEMPER. - CUT-OFF TEMPERATURE
When used with the optional temperature sensor, a safety cut-off temperature can
be set, so that charging or discharging is terminated automatically if the temperature
sensor detects the battery temperature rising above the selected value.
‘MAX. CAPACITY’ – MAXIMUM CAPACITY
The maximum capacity setting is used to terminate a charge if the charger exceeds
the selected percentage of the battery capacity.
SAFETY TIMER
The safety timer can be used to terminate a charge if it is not completed within the
selected time period.
‘CHARGE RATE’ – MAXIMUM CHARGE RATE
The charge rate allows you to set the maximum charge rate for the pack being
charged. The default is 2C, but some newer packs can allow up to 5C (5 x capacity),
so increasing this value allows the user to select a higher charge current in the charge
parameters.
TCS CAPACITY
TCS (Terminal Capacity Selection) allows the user to select a capacity at which the
charger will beep or stop charging.
Lithium batteries are charged using a constant current then constant voltage (CC-CV),
so when the cells reach their maximum voltage, the charge current is slowly reduced
until the charge is complete. Because the charge current is being reduced, the last
10-30% of the charge takes proportionally longer than the first part.
Therefore, the TCS capacity can be set to warn the user when the selected capacity is
reached, which can be useful if the user does not require a full charge in the battery,
so it can be used sooner.
‘TCS END ACT’ – TCS END ACTION
When the selected TCS capacity is reached, the charger can be set to continue the
charge and warn the user that the TCS capacity has been reached or the charger can
stop the charge.
