KOP2300 Battery charger
User`s manual
48V / 45A

1. Introduction
KOP 3 battery chargers are modern fully automatic devices suitable not only for2 00
charging but also for maintaining and monitoring the batteries. The charger stores
data about charging times and Ah charged. This data may be accessed for further
analysis. The device is protected against reverse polarity and short circuit, has
adjustable time limitations for every charging phase, battery temperature
monitoring and compensation and current reduction at elevated ambient
temperatures.
Your battery charger was programmed for a specific battery type .by your dealer
Make sure the charging profile suits your battery type. To change the charging
profile for a specific battery type, parameters can only be programmed with a PC
software package and a programming interface. The programming parameters
allow the charger's profile to suit the battery type. Up to five charging phases can be
programmed with separate values for charging voltages, currents, charging times,
temperature compensation and other control functions. Please contact your dealer
for further information.
When programming the charging profile always follow the battery manufacturer's
recommendations.
Please read the operating and safety instruction carefully
before using or installing the KOP2300 battery charger!
2. Start of the charging process
Establish a safe connection between the battery and the charger first. Then plug the
mains connector. When removing the connection, remove the mains plug from the
mains first, before disconnecting the battery.
The charger type is shown first after the charger has been connected to the mains
and then the measured values as the battery voltage – see the following page.
The charging time depends on battery size and state of charge. If the battery was
only slightly loaded, then the charging process will complete faster. At high ambient
temperatures or when exposed to strong sunlight, the charging current is reduced
and the charging time increased accordingly.
The charger can remain connected to the battery permanently. The current
consumption is less than 0. mA.from the battery 2

3. Mechanical installation
The following things must be considered during the installation:
a. Ensure the distance from the walls or other objects
Ensure the distance from the walls or other objects. Leave enough space (at
least 10cm) between the cooling openings and other objects or walls, so that
the air can circulate well.
b. Avoid the heat build-up
Despite very high efficiency quite a lot of heat arises. Therefore, the charger
must only be installed in places with enough air exchange. Otherwise, the air
temperature rises in the vicinity of the device and the charging current may be
reduced or the device may turn off.
c. Horizontal mounting
Mount the charger on a flat surface as
shown on the image. The device can
withstand higher stress due to vibration
and shock in horizontal position.the
d. Vertical mounting
The cables and terminals must be on the
lower sid as shown on the image.e
IMPORTANT:
The charger be mountedshould not
vertically in applications such as electric
vehicles, since high shock and vibrations
are common in such applications.
IMPORTANT: Observe the additional warnings (see the table). Do not make any
holes on the chassis, as components can be damaged.
Mount the charger on a flat surface.

5. Functions of the charger software (standard version)
a. Mains current limiter
The mains current, it is limited to max. 13A for 230V systems, and to max. 16A
for 120V systems. KOP2300 automatically detects the mains voltage.
Comment:
For 230V mains voltage and full output power the charger needs approx.
10.5A from the socket. At low mains voltage, the mains current would increase
at the same power, but this would be reduced to max. 13A. In the short term,
the current can also be somewhat higher than 13A in the case of very fast
mains voltage fluctuations.
If the mains voltage drops below approx. 90VAC, the KOP2300 charger is
switched off. After the mains voltage rises again, the charging is restarted
where it was interrupted.
b. CAN Bus
The standard firmware version supports the external display.
For support of special functions, like e.g. communication with the BMS, please
contact Piktronik d.o.o..
c. Relay output
The relay output is switched on when the 230V mains voltage is connected.
Other software options for the relay output on request.
d. Ambient temperature
If the ambient temperature is under -15°C when the charger is connected to
the mains then the start of charging may be delayed by up to 10 minutes. The
LED’s are OFF during this time.
If other functions are required, the charger software can also be updated later via the
CAN connector with theALL-USB programming adapter.
NOTE: The charger has very low power consumption. Therefore, depending on
the function, LED’s on the charger and the external display KOP-DIS1
can remain switched on for more than 5 seconds after the mains plug
has been disconnected.

10. General information
uRead the manual thoroughly.
uThe charger must be used with the original cables only. Do not change, shorten,
extend or short circuit the cables.
uRemove the mains plug from the mains socket first before breaking the battery
connection.
uOnly rechargeable batteries can be used. Do not connect any non- rechargeable
batteries (like dry-cell batteries) to the charger.
uThe charger must be used for the correct battery type only.
uDo not install the charger inside motor-homes, campers or caravans.
uCheck the charger for cable, housing and connector damages before use. Do
not operate the charger when damaged.
uThere are no user serviceable parts inside. Refer servicing to qualified service
personnel.
uDo not expose the charger to rain, moisture, direct sunlight or dust.
uAlways disconnect the mains after charging and generally when the device is not
in use. During the trickle charge the charger remains attached to the mains.
uObserve the warnings on the last page of this manual.

11. Warnings
COOLING
Do not cover the charger housing and protect it from direct sunlight
or other heat sources. The charging current is reduced at elevated
ambient temperatures and the charging time increases
accordingly. he built-in fan must be able to cool the electronicsT
well.
CONNECTION
Output currents are very high. Select the correct wire/cable size,
use ferrules for wire ends, keep contact points clean and properly
connect the output terminals.
FUSES
The fuse in the charger is not a sufficient protection for the battery
cable from the battery to the charger. A corresponding fuse must
be located in the immediate vicinity of the battery terminal.
MAINS
CONNECTION
The line current is limited by the charger firmware - please see
technical data. Please check if the wall socket and the mains fuse
meet this current.
BATTERY
TYPE / SIZE
Use this charger for the pre-set battery type and size only,
otherwise the battery may not be fully charged or the battery can
be damaged or it's life can be reduced.time
LITHIUM
BATTERIES
Lithium batteries are very sensitive to overcharging and
overheating. The charger can regulate only the total voltage, but
can not recognize states of individual cells. Therefore, the charger
should only be used together with a battery management system.
LEAD-ACID
BATTERY
GASSES
Lead-acid batteries produce hydrogen-oxygen gases, which can
be explosive, and sulfuric acid that can cause severe burns. Make
sure the working area is well-ventilated. Cigarettes or any open
fires or sparks may cause an explosion. Keep all ignition sources
away from the battery.
ACIDS
Battery acid can damage your eyes and skin. In the event of an
accident, flush with water and seek medical help immediately. Use
proper personal protective devices when handling a damaged or
leaking battery. Treat the material used to clean up the battery acid
spill as hazardous waste.
TOXIC
SUBSTANCES
Batteries contain hazardous materials. Among others, lead and
antimony are toxic substances. Waste lead-acid and many other
battery types are hazardous waste and must be treated according
to the Battery Disposal Regulations.
