How to charge the lithium iron phosphate battery? Correct use of lithium iron phosphate batteries

The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery. Because its performance is particularly suitable for power applications, the word "power" is added to the name, which is lithium iron phosphate power battery.

At present, the mainstream market of lithium iron phosphate battery umbilical body is applied to the electric bus market and the electric passenger car market respectively. And the related issues about the charging of lithium iron phosphate batteries are also expanding. 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, today let's take a look at the correct charging method of lithium iron phosphate battery.

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 the lithium battery pack is mainly to achieve the principle of charging when it is full, and it can be fully charged. The main purpose is 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, it can prevent overcharging when it is fully charged. For lithium-ion batteries in the industrial industry, when the battery was used in the past, the charging was relatively slow. It may take 8-12 hours for a single charge, while the lithium battery pack can achieve fast charging. A lithium battery with the same capacity as a battery will only take 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.

Last but not least, don't do it both ways. To put it simply, don't let the lithium battery work while charging. The main reason why this cannot be done is also very simple, this practice will reduce the service life of the lithium battery pack.

Unreasonable use will cause the battery to decay, thereby affecting the battery life. The following points must be paid attention to:

1. Charge frequently. 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 power in a short period of 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 cycles of charging and discharging, causing certain damage to the battery.

2. Parking at low temperature for a long time. At present, the new energy vehicle batteries on the market are mainly divided into ternary lithium batteries and lithium iron phosphate batteries. Although they perform differently in the face of low temperatures, no matter what kind of battery technology, there are batteries in the face of low temperature environments. attenuation phenomenon.

3, often low battery charging. Since there is no battery memory effect in lithium-ion batteries, electric vehicles are like our smartphones, which can be charged at any time, and try not to run out of power while charging.

4. Bigfoot throttle. Because electric vehicles have a characteristic, that is, the acceleration performance is excellent, so some car owners like the big-footed accelerator, and the feeling of pushing back comes immediately. However, it should be clear that the large current will cause a sharp increase in the internal resistance of the battery, and frequent driving in this way may even damage the battery.
