　　Key reasons for damage to lithium battery pack life

　　Key reasons for damage to lithium battery pack life:

　　Although lithium iron phosphate battery packs are also lithium-ion batteries, it can be seen from the cathode material that lithium iron phosphate batteries are the most stable batteries among lithium-ion batteries and are not high in cost. Therefore, lithium-ion batteries are increasingly used Suitable for large and medium-sized industrial production and mobile communication base stations. During the entire battery charging process, it is placed back and forth between two levels: when charging, it is deintercalated from the positive level and enters the negative level through the electrolyte solution, and the negative level is rich in lithium; when charging and discharging, it is reversely charged.

　　(1)Charging and discharging

　　Although most r03 battery now contain short-circuit fail-safe repair power circuits, in many cases this repair power circuit is not necessarily effective in actual situations and the defensive energy is limited. Under working conditions, lithium-ion batteries in lithium phosphate batteries inevitably generate heat. Generally speaking, the office environment of lithium-ion batteries in lithium phosphate batteries is between -c and c. However, the lithium-ion battery in the lithium iron phosphate battery must generate heat during and after the entire working process. Therefore, the temperature of the lithium-ion battery in the lithium iron phosphate battery is controlled at c. One of the shortcomings of lithium-ion batteries in lithium phosphate batteries is their extremely low resistance to ultra-low temperatures.

　　The operating voltage of a lithium-ion battery should not be higher than its rated value, because this will affect the charging characteristics, physical properties and safety factors of the lithium-ion battery, and may cause thermal leakage or internal leakage of the lithium-ion battery.

　　In order to make the car work more efficiently, people will increase its operating speed, and high energy density lithium ions must be selected. In short, the energy density of lithium ions is the faster the car runs. Lithium should be consistent with car load. The relationship between charge and discharge current and volume can also be obtained. The lithium charging and discharging current of a battery car is different from the charging and discharging capacity. The size of the lithium charging and discharging current will directly affect the specific capacity of the battery.

　　Excessive charging and discharging is not required as doing so may cause lithium-ion charging characteristics and battery failure.

　　(a) The content of lead, antimony and other heavy metals in lead-acid batteries is too high, which can easily cause serious environmental pollution to the natural environment. It is easy to leak during use and maintenance. If the internal hydrochloric acid flows out, it will cause corrosion of machinery and equipment and personnel safety accidents. Lithium iron phosphate batteries do not contain any harmful heavy metal elements, have zero pollution, and have a high safety factor. They are the current stage of safe r03 battery.

　　(2) Application of natural environment

　　What is the maintenance method for battery car rechargeable batteries? To correctly grasp the application of battery charging time in the entire process, battery charging time should be accurately grasped according to specific conditions, referring to the usual application frequency and mileage, and battery charging time.

　　The gas in the room should not contain corrosive vapor to ensure that the room is ventilated when the dust content in the room is low. Corrosion from steam and dust can cause damage to the internal working lines of lithium-ion batteries. This long-term nature in the natural environment will increase the frequency of common failures of lithium-ion batteries and endanger the use of internal components.

　　Lithium-ion batteries cannot be connected to lead-acid batteries due to the following reasons: charging and discharging; when the battery volumes are different, discharge once, while the other battery still works at a higher voltage; battery charging: when the battery volumes are different, First discharge and then discharge again; rechargeable battery: no battery: service life is shortened or even destroyed; overcharged battery: will be removed from the chemical reaction balance, rechargeable battery will destroy the rechargeable battery; rechargeable battery is charged in the middle: When the battery voltage shrinks, the high-load battery will be charged to the battery. If the current and the battery are increased, even if the battery is damaged at the moment, the battery will continue to charge until the battery itself.

　　However, if the lithium iron battery is overcharged and discharged, the battery in the battery pack control module will be charged and discharged first, and polarity reversal may occur at this time. According to the manufacturer, the polarity of rechargeable batteries causes sexual damage. Therefore, it plays a very important role in the control module of lithium iron battery.

　　The operating temperature of a lithium-ion battery pack is also important. Although the working temperature of lithium ions is suitable for natural environments at different temperatures from -20c to 60c, under normal circumstances, the charge and discharge capacity of lithium ions will decrease when the general temperature is less than 0c, and the service life of its circulation system will be affected to a certain extent. . Therefore, the operating temperature of lithium-ion batteries must be paid attention to.

　　Third, the output power is different from the rated power of battery cars. The rated power of battery cars will be higher or higher.

　　(3)Load

　　The rated power of the LI package refers to the key parameter of the multi-power load of the commercial energy driver. It changes with the change of the load power factor. For example, a 1kVA package may not necessarily drive a 1KVA load. In order to increase the service life of the LI package, UPS is not suitable for long-term load operation.

　　This situation is due to the inconsistent charging capacity or volume of a single string of lithium battery packs, and the use of a high or low capacity first lithium battery protection board to maintain other series of rechargeable batteries that are not satisfied with the battery charging process.
