persons.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the equipment.
This product is covered by warranty.
The relative warranty certificate is attached to the Instructions Manual.

Installation and safety instructions
Battery charger CFHC-1 has been designed to provide safety and reliable. It is necessary to observe the
following precautions in order to avoid damage to persons and to the battery charger:
• Read the installation instructions contained in this Manual carefully. For further information put the
Manual in a proper place.
• Fix the battery charger to a stable surface through the appropriate holes inserted on the fixing
flanges. In case of installation on a vehicle it is advisable to use antivibration supports.
• Preferably the charger should be installed in the vertical position with fans facing up. The horizontal
installation is allowed. Never install in the vertical position with fans facing down.
• Ensure all ventilation ports are not obstructed, to avoid the overheating. Do not put the battery
charger near heat sources. Make sure that free space around the battery charger is sufficient to
provide adequate ventilation and an easy access to cables sockets.
• Protect the battery charger from ingress of water. Do not pour liquids inside the case.
• Verify that the available supply voltage corresponds to the voltage that is stated on the battery
charger name plate. In case of doubt, consult a retailer or local Electric Supply Authority.
• For safety and electromagnetic compatibility, the battery charger has a 3-prong plug as a safety
feature, and it will only fit into an earthed outlet. If you can not plug it in, chances are you have an
older, non-earthed outlet; contact an electrician to have the outlet replaced. Do not use an adapter to
defeat the earthing.
• To avoid damaging the power cord, do not put anything on it or place it where it will be walked on. If
the cord becomes damaged or frayed, replace it immediately.
• If you are using an extension cord or power strip, make sure that the total of the amperes required by
all the equipment on the extension is less than the extension’s rating.
• Disconnect the mains supply before connecting or disconnecting the links to the battery.
• To recharge Lead Acid batteries: WARNING: Explosive Gas – Avoid flames and sparks. The battery
must be positioned in a correctly cooled place.
• Do not use to charge batteries installed on board of thermal engine cars.
• Avoid recharging of non-rechargeable batteries.
• Verify that the nominal voltage of the battery to be re-charged corresponds to the voltage stated on
the battery charger name plate.
• Verify that the selected charging curve is suitable for the type of battery to be re-charged. In case of
doubt, consult Your retailer. ZIVAN S.r.l. will not accept any responsibility in case of mistaken choice
of the charging curve that may cause irreversible damage to the battery.
• In order to avoid voltage drop, thereby assuring 100% charge at the battery, the output cables must
be as short as possible, and the diameter must be adequate for the output current.
• In the case of thermal compensation of the battery voltage, it is necessary to place the thermal
sensor in the area of highest battery temperature.
• Do not try to service the battery charger yourself. Opening the cover may expose you to shocks or
other hazards.
• If the battery charger does not work correctly or if it has been damaged, unplugged it immediately
from the supply socket and from the battery socket and contact a retailer.

Operating principle
The battery charger considerably affects battery life and performances, which is the main part of every
electric vehicle.
A non controlled traditional battery charger (rectifier) provides a simple direct AC/DC conversion.
Disadvantages of this solution are:
• Low efficiency
• Large physical size
• Long charge times
• Charge depends on changes in the mains supply (with
overcharge danger in the final charge phase)
In modern battery chargers these disadvantages are solved with an indirect AC/DC conversion, by
passing through an intermediate DC/DC conversion.
This is the usual method of operation for the
SMPS (Switching Mode Power Supply) at
high power. This solution gives a good
performance for minimum costs and physical
dimensions using switches more faster and
powerful (modern technology).
The main advantages of this solution are:
• High efficiency
• Reduced dimensions
• Short charge times
• Charge independent from the changes of the mains supply
• Electronic control that provides the desired charge curve
The advent of electrical problems (due to commutation) has imposed the introduction of adequate filtering
to satisfy requirements of EMC 89/336/EEC directive for electromagnetic compatibility.

LED Indicator
RED LED shows that the battery is in the initial charging phase.
YELLOW LED shows that the battery charger has reached 80% of charge.
GREEN LED shows that the battery has reached 100% of charge.
Further information can be found in the description of the Charging Curve.
Alarms (Two-tone audible message)
An two-tone audible message and the flashing LED shows that an Alarm situation has occurred:

Thermal Sensor and/or External Indicator
Thermal Sensor and External Indicator are Options that have to be connected to the 5 pole socket 180°.
Unless otherwise stated, the compensation of the Battery Voltage in
function of the temperature of the Thermal Sensor is of -5mV/°C for
battery cell.
The control range of the Thermal Sensor goes from -20°C to +50°C.
The External Indicator reflects exactly the LED Indicator which is placed
on the equipment.

Battery
A battery is characterised by two sizes: tension and capacity.
Tension:
Each element has a nominal tension, which depends on the type of battery (no
matter what size).
In order to reach higher tension, many elements are connected in series, so
creating a “BATTERY” of elements.
The number of elements is calculated by dividing the nominal tension of the
battery for the tension of each single element in the table:
Capacity:
It is the quantity of electric charge that the batteries can supply to an external circuit before the tension
decreases under the final limit value and it is obtained by multiplying the intensity of the discharging
current I, expressed in ampere (A), for the discharging time t expressed in hours (h): C = I x t.
The traction battery capacity is normally referred to the discharging system of 5h: C5 = I x 5h.
The capacity values that can be recharged by the battery chargers can be found in the description of the
Charging Curve (this value is not present in the curves able to charge any capacity).
