In the arsenal of every motorist there should be a car. vehicle without this device can be much more complicated. The most useful car charger can be in the winter season, when the battery has to be charged much more often. When the battery is completely discharged, you will have to “light up” the car, which is not always convenient, and in some cases may require additional expenses due to contacting the service station. It is much easier to charge the battery at home. One of the most popular car brands chargers is Kedr - devices of this brand are bought by many vehicle owners.

Model range of chargers: "Kedr-M"

Charging "Kedr-Auto" is intended for recharging car batteries. Such equipment is mainly used to restore the performance of batteries that have lost it due to sulfation and oxidation reactions of the electrodes. In addition, it is also possible to increase the service life with the help of the Kedr-Avto Mini charger by training the charge-discharge cycle.

Device Features

• Automatic termination of battery charging.

On the reverse side of the charger is a special compartment in which cords with clips and a network cable are hidden.

The voltage of the charger "Kedr-Auto 4A" can harm human health or cause death. The device must be turned off before starting restoration and repair work and changing the fuse. It is strictly forbidden to install homemade fuses and block the ventilation openings of the case. In addition, the battery must not be charged near heaters.

Before starting work, cords with terminals are removed from the rear compartment of the device. The first lever of the device is switched to the charge mode, the second - to the cyclic or continuous mode.

How to use "Kedr-Auto 4A"?

Continuous mode is used when a full charge of the battery is required.

The cyclic mode is used when forming or desulfating electrodes. In this mode, a light bulb with a power of 6 watts at 12 volts is connected to the terminals.

Then, the terminals are connected to the current outputs with respect to the polarity.

The Kedr charger has a protection mode against incorrect connection and short circuits. The instructions for the Kedr-Auto 4A charger indicate that its operation is possible only if a battery with a minimum voltage of 10 volts is connected to the terminals. When you try to restore the charge of a completely discharged battery, the device will turn on the protective mode of operation.

Switching between operating modes can be carried out without disconnecting the charger from the mains. According to reviews on Kedr-Auto, the current strength at the beginning of the charging process is 4 A, followed by a gradual decrease. The charger automatically turns off after the battery is fully charged, which is indicated by a special LED. After that, you can put the charger into recharge mode.

Charging the battery in cyclic mode lasts 45 seconds, after which a special light bulb turns on. This mode does not have an automatic shutdown, so it is desirable to control the entire process.

"Kedr-Auto 4A" and "Kedr-Auto 12V"

Both models are used for battery recovery, charging and charge-discharge training cycles.

On the rear wall of the devices are the power and connection wires to the battery. There is no special compartment for placing wires in these models. The instructions for the chargers "Kedr-Auto 4A" and "Kedr-Auto 12V" describe in detail the rules of operation and the procedure for use.

Important information for a car enthusiast who wants his battery to last a long time.

A common mistake motorists make is that they start taking care of the battery when the car can no longer be started. It is known that in the urban driving cycle the starter is often used, and during the period of short trips the generator does not have time to fully charge the battery.

Let's break down the chemistry of the process

When the battery is discharged, a white coating is deposited on the plates from the electrolyte. This is a normal process (sulfation). And if you start charging the battery in a timely manner, then it is restored. But if we allowed a deep discharge, the plaque crystallizes, and charging will not ensure the cleaning of the battery plates, it will decrease sharply.

That is why it is necessary to recharge the battery almost daily. This means cleaning the plates and keeping the battery in perfect, working condition, extending its trouble-free life for a long time. The Kedr-auto charger allows the motorist to easily cope with this task.

2. The device provides automatic transition to the mode of recharging with a small current after charging in the "AUTOMATIC" mode.

Charger Kedr Auto 4A - instruction, diagram

Everyone who has a car knows perfectly well where the colored box is, pasted over with colored stickers, why it is needed, but few people think that the battery is not eternal, and you need to at least take care of it. Only then will she be able to last the 5-7 years allotted to her. And if necessary, it needs to be recharged. And to charge correctly, and now there are all conditions for this.

Charger Kedr Auto 4a

Environment hundreds of thousands of models of chargers (chargers), many motorists prefer domestic charging. Either the genetic force of habit, or commendable patriotism, but the Kedr Auto 4a charger enjoys a certain popularity. Many have difficulty repairing this device due to the fact that the circuit is lost, and it is not always possible to find the original one. We rummaged through our archives, and dug up a device diagram, which we offer for study.

It has a simple architecture, and it’s quite easy to figure it out if you can distinguish a resistor from a canister. And if you can’t, we will try to explain what it is, why it is needed and how to use it.

When to Use the Charger

Chemistry is a delicate thing, and the battery consists of chemical processes through and through. We will not dive into the intricacies of chemistry, but we will find out what concerns the average motorist, his battery, and the Kedr Auto 4a charger.

The battery should be ok. Winter and summer. But it has an acceptable degree of discharge, which is checked quite simply - using a hydrometer, if the battery design allows, or by measuring the minimum voltage at the terminals. In the first case, we measure the density, in the second, directly the voltage. The allowable value of battery discharge in winter is 25% of the nominal value, and in summer - 50%. If the bank can hold a voltage of 1.6 V for five seconds, then it is fully charged. If the voltage is 1.4 V, then the battery is 50% dead. all arithmetic.

You need to recharge the battery, and if you chose Cedar Auto 4a, then it will do its job well if it is working properly. And the consequences of improper charging can be sad for the battery, so no matter how smart the device is, it needs to be controlled.

Description

Any rechargeable battery is charged from a source that exceeds the battery voltage, and this must be a DC source. Therefore, the charger must convert the alternating current to direct current, and at the output give us the voltage necessary for charging. The device does this excellently. Here are its technical data:

• capable of operating from a household network of 220 V ± 11 V;
• the nominal voltage of the battery it charges is 12 V;
• minimum charge current - 4.0 A;
• consumes no more than 85 watts.

Designed for both charging and restoring batteries that have lost their charge due to a number of reasons. A lot of factors can cause a voltage drop on the battery, but the most basic is the sulfation of the plates and their oxidation. Cedar is also intended for training charge-discharge cycles that restore the battery's ability to hold a charge.

Charging takes a certain amount of time, which depends on the capacity of the battery, on the degree of wear of the plates, as well as on the degree of discharge of the battery. Equipped with the simplest microprocessor that controls all possible modes of charging and operation of the device.

Functions

When the charger is connected with the correct polarity, the device starts charging the battery in automatic mode, which is indicated by the LED. In this mode, a standard battery is charged with a current of not more than 4 A with voltage control at the terminals. When the maximum value of the charging voltage is reached, the device itself is disconnected from the battery. This is indicated by a flashing LED.

To remove sulfation, you must use the "cycle" mode. In this mode, it is desirable to connect a parallel load to the battery, which consumes about 1 A of current. A 6 watt car bulb is suitable for this. If this is not done, then the process will also be successful, but it will take a little longer. To completely eliminate sulfation, it is necessary to leave the battery connected to the device for 3-5 days.

The device also has a pre-start battery charging mode. In this case, charging is faster due to the fact that a high current is applied - up to 10 A. The process lasts about five minutes. After that, the device automatically switches to the "automatic" mode, and already limits the current to 4 A.

This is how Kedr Auto 4a works. Thanks to a simple scheme, any of its malfunctions can be identified and eliminated, and the device serves for a long time. Keep an eye on the ammeter, and good luck on the road!

Safety Requirements

Be careful! The charger contains life-threatening voltage. Before replacing the fuse and carrying out repairs, unplug the charger from the mains.

Do not use a homemade fuse, this may damage the device. Do not charge batteries near stoves, radiators (at a distance of less than 1 meter).

Do not block the ventilation openings in the device case.

Preparing for work and work order

Before using the device, it is necessary to study the rules for the care and operation of batteries.

Open the cover on the back of the charger and remove the cords.

Set the toggle switch for turning on the automation to the "CHARGE" position.

The toggle switch of the charge mode "NON-REGATED-CYCLIC" allows you to select the mode of charging the battery.

If it is necessary to charge the battery, switch the charge mode toggle switch to the CONTINUOUS position.

If it is necessary to form or desulfate the plates, if the battery capacity decreases, switch the charge mode selector switch to the “CYCLIC” position. Connect the load (light bulb 12Vx6W) to the battery terminals.

Connect, observing the polarity, the cord with the clamps to the battery.

The electronic protection of the Kedr-M device against short circuit and incorrect polarity connection is designed in such a way that the charging current appears at the output only if a voltage source (battery) with a voltage of at least 10 V is connected to the output terminals.

The lamp connected to the output terminals will not light up, as it is not a source of voltage.

Operation in battery charge mode

Switching between the operating modes of the device "CONTINUOUS-CYCLIC" and "CHARGE-RECHARGE" can be done during the process of charging the battery without disconnecting it from the mains.

Connect the plug of the 220 V power cord, and the process of charging the battery begins, as evidenced by the ammeter readings.

The charge current of a fully discharged battery at the beginning of the charge can be 4 A or more, then the current will decrease during the charge process.

When the battery charge is reached, the charger automatically turns off, as evidenced by the glow of the "END OF CHARGE" LED.

Switch the toggle switch for turning on the automation in the "RECHARGE" mode and continue charging the battery. The battery is considered fully charged if the density of the electrolyte does not change during the charging process for two hours.

In the cyclic charging mode, after every 45 seconds of charging, the battery is discharged for 15 seconds through the load (light bulb) connected to the battery.

In the "CYCLIC" or "RECHARGE" position, the automation is switched off.
