How to judge the quality of lithium iron phosphate batteries?

How to judge the quality of lithium iron phosphate batteries? At present, with the rapid development of the lithium battery industry, there are more and more different types and models of lithium batteries on the market. There are also many fake and shoddy products on the market. It is recommended that consumers must have the ability to identify when selecting and buying batteries. One of the most popular batteries on the market is lithium iron phosphate batteries, so how do we judge the quality of the battery? In fact, this is roughly the same as other batteries. Four aspects are important to note, namely, battery consistency, high rate, Long life and self-discharge rate, now we will do a detailed identification of these major issues. Tools and materials: chargers, lithium iron phosphate batteries, capacitors; first of all, from the consistency of the battery, the consistency of the lithium battery pack is not good as a protection board. According to the principle of the wooden barrel, its capacity will be displayed as a minimum value. As a result, the entire battery pack battery will neither completely release electrical energy nor fully absorb electrical energy. Over time, the battery life will be short. If there is no battery protection board, not only capacity loss, not only capacity loss, but also possible safety issues Overheating and explosion, this requires the battery to be tested together, a group of 4 or 6 groups, charging 1c and 3c discharge, in the process of charging and discharging, you can see the difference in battery voltage. Self-discharge rate: Lithium iron phosphate batteries are generally used in high-power electronic products and new energy vehicle gas fields. This requires the battery self-discharge rate to be less than 2% a month. To achieve this, the consistency of the above requirements is necessary Indispensable, the consistency after the test, the detection method of the self-discharge rate: equal to the battery charging capacity, let stand for a month, and measure the capacitance value. Generally speaking, the power lithium battery pack should meet the safety requirements of 3C charging and 30C discharging. If the battery pack can withstand high-rate charging and discharging, it has stronger rapid charging and discharging capabilities. Regarding the lithium iron phosphate battery, it must be able to charge and discharge quickly to meet the requirements of its power lithium battery. The test method is: according to the data provided by the lithium battery manufacturer and then verify the data, because the entire product design process is in accordance with unified product control The method is refined, if the difference is not big, the battery can meet the optional conditions of purchase, if it is different from this is a low-quality product, good or bad, known tests recommend choosing an internationally renowned company, product quality assurance.
