The full name of lithium iron phosphate lithium ion battery is lithium iron phosphate. The P-0 in lithium iron phosphate crystal is stable and hard to distinguish. Even at high temperature or overcharge, it will not collapse and heat or form strong oxidizing substances like lithium cobalate, so it has good safety, and its low temperature performance and consistency will be slightly worse than ternary. They are respectively applied to the electric bus market and the electric passenger vehicle market. However, the charging of lithium iron phosphate battery has always been controversial.
Does the lithium iron phosphate battery need to be charged every day? How often is the lithium iron phosphate battery charged? Can lithium iron phosphate battery be charged anytime and anywhere? Today, let's take a look at how to use lithium iron phosphate battery.
Combined with the working principle of lithium battery pack, the correct use method mainly includes three aspects: charging, discharging and maintenance.
First of all, in terms of charging, the correct charging method of lithium battery pack should be based on the principle of charging when charging, and charging when fully charged. The reason is to avoid overcharging during the use of the 48v lithium battery pack, that is, to charge the lithium battery pack when the battery is nearly fully used.
Second, it can be fully charged to prevent overcharge. For lithium ion batteries in the industrial industry, charging was relatively slow when using the battery before, and it may take 8-12 hours to charge at a time, while the lithium battery pack can achieve fast charging. For lithium batteries with the same capacity as the battery, it only takes about 4 hours to fully charge at a time, so pay attention when charging, Do not charge the lithium battery pack according to the charging time of the battery.
The last point is not to be dual-use. The popular point is not to let the 48v 100ah lithium battery work while charging. The reason is simple. This will reduce the service life of the lithium battery pack.
The above are the conditions that will occur during the charging process of lithium iron phosphate batteries. Improper use methods will lead to battery attenuation, which will affect the battery life. Therefore, you must pay attention to the following points:
1. Do not always choose fast charging for the sake of convenience. Although fast charging is a good function, frequent use of fast charging will reduce the reduction capacity of the battery, thus reducing the number of charging and discharging cycles, causing certain damage to the battery.
2. Park for a long time in a low temperature environment. Power batteries are mainly divided into ternary lithium batteries and lithium iron phosphate batteries. Although they perform differently in the face of low temperatures, no matter which battery technology, there is battery attenuation in the face of low temperatures.
3. Use low battery before charging. Since lithium ion batteries do not have battery memory effect, they can be charged as soon as they are used. Try not to use up the power before recharging.
