Battery pulse charging is a method of charging the battery intermittently with a large current pulse. In the pulse charging process, the battery voltage rises rapidly, the voltage gradually decreases after the fixed charging time, and the next pulse charging begins when the current voltage is lowered to the set voltage. With the progress of pulse charging, the stop time is gradually extended, and the duty cycle of pulse current is decreasing. When the duty cycle reaches 10% to 5%, the battery is considered to be full. This charging method has the characteristics of fast charging speed and large charging current, but there are also some shortcomings, such as when the grid voltage fluctuates, the charging current also fluctuates, and it is easy to cause high battery temperature rise and large electrolyte loss due to large charging current, thus damaging the battery. Therefore, this method is rarely used in maintenance-free sealed lead-acid batteries.
Battery pulse charging is a charging method that uses pulse current to charge the battery. This method first charges the battery with a pulse current, and then lets the battery discharge a large pulse for a short time to complete the entire charging process. The advantage of pulse charging is that it can greatly shorten the charging time, which is conducive to eliminating the memory effect of the battery and restoring the original crystal structure of the plate.
Battery pulse charging is a method of charging a battery by applying an electric current in the form of a pulse. During this process, the battery is charged with alternating pulses of current, rather than constantly applying a constant current. This method can effectively reduce the chemical reaction process inside the battery, thus reducing the heat and gas generated during the charging process. In addition, pulse charging can also reduce the polarization effect of the battery, extend the life of the battery, and charge the entire battery more evenly, reducing overcharge and overdischarge during the charging process. Therefore, battery pulse charging is widely used in various types of battery charging systems, including lead-acid batteries, lithium batteries and so on.
