What are the differences between lithium iron phosphate battery and lead-acid battery charger

The charging control method of lead-acid battery and lithium iron phosphate battery charger is different. The voltage levels of lithium batteries and lead-acid batteries do not match. There are also many types of lithium batteries, and battery performance and battery protection board parameters may be different. Lithium iron phosphate battery charge control is to charge according to a constant current first, and then when the battery voltage rises to 4.2V, the voltage does not rise again, and the charger tests the current. If the current is less than a certain value, the charging ends. Lithium batteries are sensitive to overcharge, so the protection circuit is complicated. For a single cell of nominal 3.6V battery, the highest charging rated voltage is 4.2V, and the allowable upper limit of error is not more than 1%. For lead-acid batteries, the ideal charging current is pulse type. Pulse charging is best with the 50-60HZ mains power supply that we use. Direct rectification and unfiltered pulsating DC charging is the best. Due to the relatively large self-discharge rate of the battery, when using power frequency charging, Generally, a constant voltage charging method is used. Since lead-acid battery chargers are generally set to 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 charge the battery, and the lead-acid battery cannot charge the lithium battery, because the safety requirements of 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 extend the service life of the battery. It adopts a 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.
