The worst part about sulfation is even though you can get rid of sulfation, the process itself cannot be reversed. If the battery is not fully charged, the lead sulfate inside it will start taking crystalline shape at the battery terminals, leading to sulfation. The only way of preventing sulfation is to let your car's battery charge fully. However, neither charging method is better than the other. These chargers use positive pulses with brief negative pulses between positive ones to charge the battery. The other type consists of chargers using negative pulse charging (also called reflex or burp charging). The first type is the regular type where upon connecting with the battery, the charger uses pulses to check the state the battery is in, then uses constant current charging for the initial phase and switches to pulse charging later to maintain the charge. Typically, a contactless battery charger with voltage fed inverter uses a resonant tank to transfer power. The focus is on implementing a high-frequency sinusoidal pulse-charging topology with an interleaved rectifier for twin battery banks. Yes, there are two major types of pulse chargers. This work develops a novel high-frequency sinusoidal pulse-charging method that is based on a contactless battery charger for use in mobile service robots. Q.Are there different types of pulse chargers?

This leads to breaking down of sulfate crystals, thereby increasing a battery's service life. Q.How does a pulse charger reduce sulfation?īy sending current in pulses, a pulse charger can charge a battery by applying high, instantaneous voltages without overheating the battery. A pulse charger is said to work with both regular and valve-regulated batteries. These pulses carry DC current and have a strictly-controlled rise time (time taken by a signal to change from specified low value to specified high value), pulse width, frequency and amplitude.
