At present, the mainstream market of lithium iron phosphate batteries is used in the electric bus market and the electric passenger car market respectively. The related issues about lithium iron phosphate battery charging are also constantly amplified. For example, can lithium iron phosphate batteries be charged every day, can lithium iron phosphate batteries be charged at any time, and so on. So, let's take a look at the correct charging method for lithium iron phosphate batteries.
Combined with the working principle of the lithium battery pack, its correct use mainly includes three aspects: charging, discharging, and maintenance.
First of all, in terms of charging, the correct charging method of lithium battery packs is mainly to achieve the principle of charging when charging, and charging when fully charged. It is mainly to avoid overcharging during the use of the lithium battery pack, that is, to charge the lithium battery pack when the battery is nearly fully used.

Secondly, full charging can prevent overcharging. For lithium-ion batteries in the industrial industry, charging is relatively slow when using batteries in the past. It may take 8-12 hours for a single charge, while lithium battery packs can achieve fast charging. A lithium battery with the same capacity as the storage battery only takes about 4 hours to fully charge at a time, so pay attention when charging, and do not charge the lithium battery pack according to the charging time of the storage battery.
The last point is not to use two things at once. In layman's terms, don't let the lithium battery work while charging. The main reason why this cannot be done is also very simple. This approach will reduce the service life of the lithium battery pack.
Improper use will lead to battery attenuation, which will affect battery life. The following points must be paid attention to:
Fast charge often. Many new energy vehicles support fast charging mode, so many car owners will choose fast charging to charge the car with a certain amount of electricity in a short time to ensure the normal driving of the vehicle. Fast charging is a good function, but frequent use of fast charging will reduce the battery's restoring ability, thereby reducing the number of charge and discharge cycles and causing certain damage to the battery.
Long time storage at low temperature. At present, the new energy vehicle batteries on the market are mainly divided into two types: ternary lithium battery and lithium iron phosphate battery. attenuation phenomenon.
Frequent low battery charging. Since lithium-ion batteries do not have a battery memory effect, electric vehicles are like our smartphones, which can be charged as they are used, and try not to run out of power before recharging.
Big foot on the gas. Because electric vehicles have a characteristic, that is, excellent acceleration performance, so some car owners like to use the
Big foot on the gas. Because electric vehicles have a characteristic, that is, excellent acceleration performance, so some car owners like to use the accelerator with a big foot, and the feeling of pushing back comes immediately. But it must be clear that large current discharge will increase the internal resistance of the battery sharply, and frequent driving in this way may even damage the battery.
