What is the difference between lithium iron phosphate battery and lead-acid battery

        The charging control methods of lead-acid batteries and lithium iron phosphate battery chargers are different. The voltage levels of lithium batteries and lead-acid batteries do not match. There are many kinds of lithium batteries, and the battery performance and battery protection board parameters may be different.

        For lead-acid batteries, the ideal charging current is pulse type. Pulse charging is best with the 50-60HZ mains power used for direct rectification and unfiltered pulsating DC charging. Due to the relatively large self-discharge rate of lead-acid batteries, when using power frequency charging, Generally, a constant voltage charging method is used.

        Since lead-acid battery chargers are generally set to a two-stage or three-stage charging mode, the voltage levels of lithium iron phosphate batteries and lead-acid batteries do not match. If the voltage is the same, the lithium battery can be charged with the lead battery, but the lead-acid battery cannot be charged with the lithium battery, because the safety requirements of the lithium battery are higher.

       The battery charger organically combines high-frequency switching power supply technology with embedded microcomputer control technology, and uses intelligent dynamic adjustment technology to optimize the charging characteristic curve and effectively prolong the service life of the battery. It adopts the four-stage charging method of constant current/W stage/constant voltage/small constant current, which has the characteristics of high charging efficiency, high reliability, easy operation, light weight and small size.

        The lithium iron phosphate battery pack can not be charged with a lead-acid battery charger. If the voltage is the same, the lithium battery can be charged with the lead-acid battery, but the lead-acid battery cannot be charged with the lithium battery, because the safety requirements of the lithium battery pack are higher. These two types of chargers cannot be mixed, otherwise the battery will be scrapped directly. Because the charging modes of lithium battery chargers and lead-acid battery chargers are different. Lithium batteries are charged at constant current and constant voltage, and lead-acid is charged in three stages.

        Since lead-acid battery chargers are generally set to two-stage or three-stage charging mode, the voltage levels of 48V lithium iron phosphate battery packs and lead-acid batteries do not match. There are many kinds of lithium batteries, and the battery performance and battery protection board parameters may be different. Therefore, lithium battery packs do not have universal battery chargers like lead-acid batteries. Generally speaking, lithium battery packs are equipped with special chargers when they leave the factory. In order to protect the lithium battery, a special charger is required.

        The charger should be used for special vehicles, and what type of battery should be matched with the charger. If the current is too high, the active material of the plate will fall off, causing the battery to not be fully charged; if it is too low, the battery will not be able to accept effective charging, which will cause the battery to not be fully charged; if the voltage is too high and overcharged, the current will exceed itself. capacity, will cause the battery to bulge.

        Lead-acid battery charging principle Acid battery electrodes are lead and its oxides, and the electrolyte is sulfuric acid solution. When discharging, the positive electrode is mainly a lead-antimony-calcium alloy fence, which contains lead oxide as the active material, the negative electrode active material is lead, and the positive and negative electrodes are lead sulfate during charging. When charging, an external DC power supply should be connected to restore the material generated by the positive and negative plates after discharge to the original active material, and convert the external electrical energy into chemical energy for storage.
