The charging control methods of lead-acid battery and lithium-ion battery chargers are different. Since شواحن بطاريات الرصاص الحمضية are generally set to two-stage or three-stage charging mode, the voltage levels of lithium-ion batteries and lead-acid batteries are not matched. There are many types of lithium-ion batteries, and the battery performance and battery protection board parameters may be different. Therefore, lithium-ion batteries are not the same as lead-acid batteries, and there are universal battery chargers. Generally speaking, lithium-ion batteries are equipped with special chargers when they leave the factory. In order to protect lithium-ion batteries, a special charger is required.

The charging control of lithium-ion batteries is to charge at a constant current first, and then when the battery voltage rises to 4.2V, the voltage will no longer rise. The شاحن بطارية الليثيوم detects the current. If the current is less than a certain value, the charging is terminated. Lithium batteries are sensitive to overcharging, so the protection circuit is complex. The maximum charging rated voltage for a single nominal 3.6V battery is 4.2V, and the upper limit of the allowable error is not more than 1%.

The ideal charging current for lead-acid batteries is pulsed. Pulse charging is best performed by directly rectifying and unfiltering the pulsating DC power supply of the 50-60HZ mains we use. Since the self-discharge rate of lead-acid batteries is relatively large, constant voltage charging is generally used when charging at industrial frequency.

Lead-acid battery chargers organically combine high-frequency switching power supply technology with embedded microcomputer control technology, and use intelligent dynamic adjustment technology to optimize the charging characteristic curve and effectively extend the service life of the battery.
