What is a battery charger?

The charger only allows you to charge the battery pack. To do this, the battery must be disconnected from the vehicle. The charging process itself takes a long time. Depending on the charger design, it can take anywhere from 4 to 14 hours to fully charge the battery. Also, on some vehicles, disconnecting the battery from the car is not recommended.

Charging a dead battery is not difficult with the proper equipment. Batteries are commonly referred to as chemical sources of electricity, restoring energy through the use of an external electric field. A car charger supplies electricity to the power source, bringing it back to working condition. A charged battery is the key to the stable operation of all systems because a modern car is unthinkable without electronics.

Even with a stable alternator, the power supply can be discharged. This occurs due to the consumption of significant amounts of electric car systems, gradually discharging the battery. It can be completely discharged without turning off the exterior lights and multimedia system.

Charging devices for vehicle power sources have the same principle of operation. Charging devices for vehicle power sources have the same principle of operation. They reduce the voltage of the regular network to normal, rectify the current and automatically charge the dead battery. The car owner has only to install the charger terminals on the battery and connect it to the permanent electricity.

The problem of selecting a device to charge the car battery should be considered by the car owner quite responsibly and carefully. The choice of this unit depends on the life of the power source, which has a fairly high cost. Purchased products should be factory assembled, meet the relevant safety standards, have clear instruction and clear parameters of functioning. The most acceptable charging devices are those that function automatically. They can provide the most effective process with minimal human involvement.

Compatibility with the battery of your vehicle will be important when choosing a device. This parameter is selected according to the capacity. If the mismatch is large enough, both devices will last a short time. Mutual matching of the strength of the electric current is also required. This parameter is measured in amperes. If there is an adjustment of the current strength on the charger, the maximum value is taken into account.

As a rule, such mechanisms do not have a control panel, and only need to be connected.

According to the principle of operation, chargers are divided into:

   - Pulsed devices, acting by the high-frequency current.
   - Transformer car battery charger.

Pulsed chargers are more compact. Transformer ones are cheaper but quite massive, so they are gradually being displaced from the charger market. Let's consider this in more detail.

What is the difference between a transformer charger and a pulse charger?

During prolonged, complete discharge of the power source, a process of sulfate formation on the lead plates of the battery occurs. This leads to a gradual deterioration of its qualities, wastes more charging time. Therefore, it is necessary to carefully monitor the charge level and prevent it from discharging. Maintaining the battery charge is the key to the normal operation of the vehicle, which will prevent unpleasant surprises.

To list the most important differences between pulsed and transformer devices, it is necessary to consider the history of their emergence, as well as to break down the principles of the charging process. Designs to restore the power of batteries appeared at the same time as the latter. Since their advent, the method of charging has remained the same, it involves applying either direct current or direct voltage. Considering that separately these methods have rather significant disadvantages, a device combining them was designed. This reduced the charging period and significantly reduced the wear and tear on the instruments.

Today, with the help of the latest devices, power sources receive conventional charging in two stages. First, there is a direct current that charges the power source, which then changes to an alternating current. Switching modes for getting more results is done automatically. As a result, better charging occurs.

Transformer-based chargers have been being used to charge car batteries for a long time. The design of these devices is extremely elementary, the main function is performed by a transformer and a rectifier. The electric current of 220 volts due to the device is converted into a value equal to approximately 14.5 volts. These devices function mainly based on direct current. At the beginning of the process, it is necessary to manually set the current intensity not more than 1/10 of the battery capacity, it is a manual charge of the battery. The voltage change takes place dynamically, taking into account the level of discharge. Such equipment is not quite convenient to use, given its size, also, there is a heating of the car charger.

The main difference, which has a pulse charger, is that the recovery of the battery is not a constant current, but the current is supplied in pulsed mode. A ferrite ring acts as a high-frequency transformer here, with the secondary winding of one the necessary voltage is obtained. This makes it possible to avoid using bulky, heavyweight transformers. The design has small dimensions and automated operation options, i.e. automatic charging of the battery, that allows accelerated charging of the battery without the personal participation of the car owner.
