What are the differences between lithium iron phosphate batteries and battery chargers?

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. Because the battery self-discharge rate is relatively large, 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 be used to charge the battery, and the lead-acid battery cannot be used to 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, simple operation, light weight and small size. The intelligent battery charger can automatically use constant current fast charge, trickle floating charge, and automatic stop charging when overflowing according to the different conditions of the battery voltage. At the same time, the diesel engine intelligent battery charger has automatic overcurrent and short circuit protection functions. Compared with floating chargers generally used in the industry, battery chargers have the advantages of guarding against battery damage and prolonging service life. Widely used in railways, civil aviation, communications, and electricity. Lithium battery charger is a charger specially used to charge lithium battery. Lithium iron phosphate batteries have higher requirements for chargers and protection circuits, so lithium battery chargers usually have higher control precision and can charge lithium batteries with constant current and constant voltage.
