Fusion L702B operating instructions CUT.TEMPER. CUT-OFF Temperature

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.
