That is why the pulsers are more often found in car service centers, service stations and private workshops. Looking at the price, most buyers immediately go to the shelf with transformer chargers. The first is the relatively high cost of the device. If the battery is connected incorrectly or the wrong mode is selected, an alarm and information on the display will tell what to do to properly charge the battery.Īnd what can be said about the negative aspects of this charger? Here we should highlight a couple of main points. A prompting system is integrated in some PSUs.The automatic mode prevents the battery from overheating and prolongs the service life of the battery. Pulse chargers have all sorts of protection against shorts, polarity reversal, etc.The software in the most modern PSUs excludes human presence in the process of charging, or at least its participation is reduced to a minimum.Ease of operation: even a person who is not sophisticated in the intricacies of electronics can figure out how to operate the device.Therefore, the charger is easy to take with you on a long trip in severe frost, so that after the overnight stay you will not have problems with starting the engine. Small dimensions: some pulsers can be freely placed even in the glove compartment of the car.What is the reason for the popularity of pulse devices among motorists? There are quite good reasons for this: BOOST can be used only in extreme cases: when you need to travel urgently, and the battery was discharged. At the end of this period, the engine will start even if the battery has been severely discharged.īut frequent use of this mode is undesirable: the constant strong impact on the electrode-plates will quickly lead to their destruction, and the battery will lose its performance finally after 2-3 months. This is an emergency mode that provides recharging the battery for a maximum of 10 minutes. But many pulsers also have a special method of battery recovery called BOOST. The battery can be charged with constant current, voltage or a combined mode, as will be described later. It will take 14 to 20 hours to fully charge the battery. Automatic machines: programmable devices, capable of first determining the state of the battery, then choose the best mode of its recovery and charge with the subsequent automatic shutdown.įull-fledged charging of the battery with a pulse device can not occur at a shock rate.Semi-automatic: here part of the process occurs without the participation of the car owner – he only needs to consider the duration of the procedure.Manual: relatively inexpensive devices that require constant control of the charging process: that is, you will have to periodically adjust U and I, monitor the time of the process.In the store you will find several types of PSUs: FeaturesĪll pulse chargers are uncomplicated in operation and have their own classification. At the end of the process, the diode rectifier is blocked and charging stops. A current is supplied to the battery, the value of which is controlled by additional electronic units. Then it is converted and simultaneously decreased to the required value. At the same time, filters (which include electrolytic capacitors) are actively used, detaining interference and smoothing the voltage at the output. How does a PSU work? The electronic circuit and the transformer generate a high frequency, by which the input voltage from the mains is increased.
