Several charging methods for lithium battery packs

Lithium iron phosphate batteries and ternary lithium batteries are different. In today's power lithium-ion battery market, lithium iron phosphate batteries and ternary lithium batteries occupy the entire market. The two compete with each other and let us see their differences. Energy density is the foundation of power lithium-ion batteries and the key to the endurance of electric vehicles. Of course, safety is also the most important. The emergence of lithium iron phosphate batteries is one step earlier than lithium ternary batteries, and its energy density is much lower than that of lithium ternary batteries. But in terms of safety, lithium iron phosphate batteries occupy the first place. Regarding their safety, we can see from the materials they use. The materials used in lithium iron phosphate batteries decompose at around 700c, while the materials used in ternary lithium batteries decompose at around 200c. Regarding self-igniting lithium batteries, higher heat resistance also means higher safety. Not only are the two key differences in safety and energy density, but also in temperature adaptability and charging and discharging frequency. At high temperatures, the two lithium batteries are not much different, but the ternary lithium battery is better at low temperatures. Charging and discharging power is also an important part of power lithium battery. As a high-tech product, ternary lithium battery is better than lithium iron phosphate battery. When many people see the charging method, they want to say that charging is not about insufficient plug ports. As the manufacturers of lithium battery processing and matching chargers tell you, it is not that simple. Lithium battery pack charging is a variety of structural methods. The general method of charging in series, the current charging method of lithium battery packs on the market is this, this method is mainly of low cost and simple structure. But this method also has certain problems, it is easy to overcharge, and overcharge will cause the battery function to decline or even explode and catch fire. A series of charging chargers and battery handling systems means that the charger and battery handling system must have a well-coordinated series of charged lithium batteries, which can prevent overcharging, especially the number of solutions to problems. The series of lithium batteries and batteries are consistent. Sex. Compared with serial charging, parallel charging can prevent problems such as overcharging and dissatisfaction. The disadvantages are high cost, low charging efficiency, and low reliability. Therefore, there is no large-scale use of this charging method.
