Startup
Table 5 - Rectifier output settings
Table 6 - Operating LED legend
Note: Refer to 10. Troubleshooting if ABNORMAL
LED is active.
To shutdown the Evolion
®
when
connected to the application:
• Turn OFF the battery output
breaker.
• Push the Evolion’s ON/OFF button
for at least 4 s.
When the Evolion
®
is OFF, the LED’s
are inactive.
7. Operation
The Evolion
®
is a “smart battery” and
will only allow safe operation. If a key
operating parameter is exceeded, the
Evolion
®
will automatically interrupt
or restrict its operation until the key
operating parameter is back within
acceptable limits. In this case the
alarm will be reset and operation will
continue normally. Some alarms are
only resettable by the BMST reset
button or by sending a BMST reset
command on the RS485/Modbus
communication bus.
The Evolion
®
is an RS485/Modbus
slave. Any user configured RS485/
Modbus master equipment can
communicate with the Evolion
®
. See
the Evolion
®
communication user
manual for more details
The Evolion
®
is equipped with an
internal heater. It operates as
needed in charge and discharge
mode of operation.
During operation, the LED’s are
active and indicate the Evolion’s
status. See Table 6.
Charging
Make sure that output of the
rectifier is set as 56.0 V ± 0.5%.
It must be set higher than 49.0 V to
allow cell balancing during re-charge.
Temperature Compensated Voltage
(TCV) should be disabled. The Evolion
®
is not harmed by TCV control but the
available capacity will be decreased by
10% for every 1 V below 56.0 V.
• When Evolion
®
is used in “floating
operation”, for which re-charge
time is not critical, the charge
current can be limited to 16 A per
Evolion
®
module.
• When Evolion
®
is used in “cycling
operation” the maximum current
will depend on the operating
temperature. Refer to Table 7.
• If the maximum allowed charged
current (IMR) is exceeded, the
Evolion
®
will automatically regulate
its own charge current by switching
to regulated charge. In that case,
the charge can last 24 h.
To start up the Evolion
®
when
connected to the application:
• Switch ON the rectifier/breaker
output.
IMPORTANT:
Do not use the ON/
OFF button to switch ON the Evolion
®
when it is connected the power bus.
This may cause a fuse fault.
When the Evolion
®
is ON, the LED’s
are active indicating its operational
status (see Table 6).
The Evolion
®
will accept charge
current only when the temperature
is above - 30°C and below +75°C
(- 22°F and +167°F).
Discharging
The Evolion
®
will discharge above
- 30°C and below +75°C (- 22°F
and +167°F). The maximum allowed
discharge current is a function of
temperature.
IMPORTANT:
If an Evolion
®
is
subjected to more than 130 A (5 kW
@ 42 V) of continuous discharge
current, a fuse fault will occur. See
Section 10 for fuse replacement.
The Evolion
®
will continuously
discharge until one of the following is
encountered.
• The rectifier output power returns,
or
• The battery reaches the minimum
set SOC (0% by default), or
• No discharge current is present
for a set time duration (default is
0), or
• The ON/OFF button is pushed for
at least 4 s, or
• The maximum allowed discharge
current is exceeded, or
• The low voltage disconnect is
reached (default is 42.0 V).
When the end of discharge is
encountered due to a low end
voltage, the Evolion
®
will eventually go
into sleep mode when the a low cell
voltage is reached.
IMPORTANT:
After the end of
discharge to 42 V, the Evolion
®
can remain in sleep mode for a
maximum of 14 days. If re-charge
does not begin within this time, the
Evolion
®
may be over discharged due
to its internal self-discharge. If over
discharged, it will not startup and
will indicate a major alarm that is
not resettable. The unit will need to
be replaced.
