Introduction
The BLUESHAPE series of intelligent lithium-ion battery chargers
have been specifically designed for fast and reliable charging of
BLUESHAPE batteries. The charging speed depends on the type of
batteries on charge since the charger communicates and acquires
information from the batteries during operation. The charger is
capable of delivering up to a maximum of 6Amps in constant current
(CC) mode on all eight channels simultaneously. This makes it ideal
for fast turnaround, especially when using higher capacity batteries.
However, when charging smaller batteries, the charger never
exceeds currents higher than 0.5C* to avoid overheating and stress
to the lithium-ion cells.
Nevertheless, these chargers can also charge 3rd party, non-
communicative batteries but at a fixed rate. A precaution is included
by design in order not to overcharge 3rd party batteries or render
them unsafe.
This charger has been designed for users having large fleets of
batteries, and with a higher daily rotation; the wall mounting feature
and the flat form factor makes it discrete and minimally intrusive in
any installation.
This charger features a 3.5” touch display for intuitive and direct
access to charger control and information.
*0.5C is equivalent to half the battery Ah capacity
Features of CVS8XW
 Elegant and robust design. Ideal for indoor use.
 Sophisticated electronics for accurately detecting the charging
requirements and applying the correct charging rate accordingly.
 Simultaneous charging of 8 batteries at a maximum of 6A each
when fan is switched on.
 3.5” touch display with adjustable backlight
 Pre-charge function for protecting heavily discharged cells
against high currents until their voltages rise to a safe level .
 Maximum compactness and space utilisation.
 Switchable fan for selection of ‘FAST’ or ‘SILENT’ charging
modes.

12
 Precise constant current (CC) and constant voltage (CV)
charging algorithms to match the battery programmed charging
voltage.
 Powerful auxiliary output at 14.4V / 115W through 4-pole XLR
 If AC mains is not present or is suddenly cut off, the AUX power
is drawn from the batteries and the equipment operates as a
UPS and continues delivering power.
 If the battery is placed on charge, the AUX power will be derived
from both mains and battery if necessary
 USB connection to interface the charger with a PC: up to 4
chargers can be monitored by a single PC using BSCVMon - a
custom BLUESHAPE software for tracking and monitoring
chargers and logging battery fleet history.
BLUESHAPE Battery Charging and Performance
Features
The electronic circuitry provides a very accurate lithium-ion charge
algorithm. Initially, the chargers will only apply a pre-charge current of
a few mA to batteries that are heavily discharged. Once the cells
inside the batteries reach a safe level, the full (maximum) charging
current is delivered at a maximum rate of 6A (but less than 0.5C)
until the batteries reach almost 90% state of charge (SOC).
This charging rate is only applied when the fan is set to ON. If the fan
is switched to OFF for silent operation, the charging current is
reduced to not exceed 4A (but less than 0.5C).
After the constant current (CC) phase is completed, a constant
voltage (CV) phase initiates with the current tapering slowly to 150mA
until full cut-off.
*The output voltage of the auxiliary output is
dependent on the battery voltage. It can
therefore range between 12.5V up to 17V

Working with AC Input
When AC is present and no batteries are installed, the power
available on the AUX port depends on the fan state:
 with fan set ON - 14.4V regulated at max 10A
 with fan set OFF - 14.4V regulated at 8A
Whenever a battery is connected in charge, the max available power
on the AUX port depends on the power of the installed battery since if
the load on AUX exceeds the available current, the extra power is
provided by the battery that in such case is getting discharged. The
maximum current is capped at 8A.
When a battery is in charge and the AUX is powered, please note
that AUX takes priority:
 The available current is shared between the battery on charge
and the load on the AUX port. Therefore, the charging current is
reduced when the AUX is draining power.
 If the AUX port demand is less than the current that is able to be
drawn from the charger then the remaining current will be used
to charge the battery.
 If the AUX port demand greater than the current that is able to be
drawn from the charger then the battery will go into discharge to
supply the rest of the demand
See the technical specifications table in this manual to understand
the different current handling under different conditions.
Using the Charger as an Auxiliary Power Supply
In the case when a device is plugged into the auxiliary XLR port, the
charging process may continue but can be slowed down, depending
on the power taken by the AUX port that has the priority.
When a device is powered by the AUX port and at least a battery is
installed, the unit operates as an UPS: in case of a sudden AC power
cut, the device remains powered if at least a battery is installed and
its voltage is higher than 12500mV.
Once the device has been unplugged, the charger will continue the
previous charging sequence and from the same point of interruption.
The AUX port is always available whenever AC is connected or at
least one battery is present and with a voltage greater than
12500mV.
