Skylla-i 24V 80A

Skylla-i 24V 80A
Skylla-i Battery Charger 24V
Li-Ion ready
Aluminium epoxy powder coated cases with drip shield and stainless steel fixings withstand the rigors of
an adverse environment: heat, humidity and salt air.
Circuit boards are protected with an acrylic coating for maximum corrosion resistance.
Temperature sensors ensure that power components will always operate within specified limits, if needed
by automatic reduction of output current under extreme environmental conditions.
Next to a CAN bus (NMEA2000) interface, a rotary switch, DIP switches and potentiometers are available to
adapt the charge algorithm to a particular battery and its conditions of use.
Please refer to the manual for a complete overview of the possibilities
Important features:
The right amount of charge for a lead-acid battery: variable absorption time
When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of
the battery. After a deep discharge the absorption time is automatically increased to make sure that the
battery is completely recharged.
Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage
has been chosen, the Skylla-i will prevent damage due to excessive gassing by automatically limiting the
rate of voltage increase once the gassing voltage has been reached
Skylla-i 24/100
Less maintenance and aging when the battery is not in use: the Storage mode
The storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In
the storage mode float voltage is reduced to 2,2 V/cell (26,4 V for 24 V battery) to minimise gassing and
corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘refresh’
the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early
battery failure.
To increase battery life: temperature compensation
Every Skylla-i comes with a battery temperature sensor. When connected, charge voltage will automatically
decrease with increasing battery temperature. This feature is especially recommended for sealed lead-acid
batteries and/or when important fluctuations of battery temperature are expected.
Battery voltage sense
In order to compensate for voltage loss due to cable resistance, the Skylla-i is provided with a voltage
sense facility so that the battery always receives the correct charge voltage.
Suitable for AC and DC supply (AC-DC and DC-DC operation)
The chargers also accept a DC supply.
Use as a power supply
As a result of the perfectly stabilized output voltage, the Skylla-i can be used as a power supply if batteries
or large buffer capacitors are not available.
Two outputs to charge 2 battery banks
The Skylla-i features 2 isolated outputs. The second output, limited to approximately 4 A and with a slightly
lower output voltage, is intended to top up a starter battery.
Li-Ion (LiFePo4) ready
Simple charger on-off control can be implemented by connecting a relay or open collector optocoupler
output from a Li-Ion BMS to the remote control port of the charger. Alternatively complete control of
voltage and current can be achieved by connecting to the galvanically isolated CAN bus port.

BMV 600S Battery Monitor
Skylla-i Control
The BMV 600S Battery Monitor
features an advanced
microprocessor control system
combined with high resolution
measuring systems for battery
voltage and charge/discharge
The software includes complex
calculation algorithms, like Peukert’s
formula, to exactly determine the
state of charge of the battery. The
BMV 600S selectively displays
battery voltage, battery current,
consumed Ah or time to go.
The PCC panel provides remote control
and monitoring of the charge process
with LED indication of the charger
status. In addition, the remote panel
also offers output current adjustment
that can be used to limit the output
current and thus the power drawn from
the AC supply. This is particularly useful
when operating the charger from
limited shore power or small gensets.
The panel can also be used to change
several battery charging parameters.
