According to the recommendation of Keheng new energy manufacturer, maintain the lifepo4 battery pack according to the following methods
In order to prolong the service life of the lithium battery pack and avoid potential safety hazards. .
maintenance guide for lifepo4 battery pack
(1). The operating environment requirements of lifepo4 battery pack
According to the environmental requirements of the battery, the room temperature should not exceed 55°C, and it is recommended that the ambient temperature should be kept between 0°C and 55°C. Avoid direct sunlight on the battery, and the sun-facing windows should be shaded. Make sure to leave enough maintenance space between the lithium battery packs.
(2). Precautions for use of lifepo4 battery pack
Lifepo4 battery packs of different specifications and models are prohibited from being used in the same DC power supply system, and batteries with different degrees of old and new should not be mixed in the same DC power supply system. If there is a power and environment centralized monitoring system, the total voltage, current, single module voltage, temperature, and capacity of the battery pack should be monitored in real time through the dynamic environment centralized monitoring system and BMS. At the same time, the battery monitoring device is used to understand the battery charge-discharge curve and performance, conduct actual measurements on a regular basis, and deal with faults in a timely manner.
(3). Items frequently checked by lifepo4 battery pack
Always check whether the poles and connecting strips of the lifepo4 battery pack are loose. Whether there is damage, deformation or corrosion. Whether the connection is loose, whether the battery case is damaged, leaking or deformed, and whether the temperature rise of the battery and the connection is abnormal. According to the technical parameters and on-site environmental conditions provided by the manufacturer, check whether the voltage of the battery pack and the single module meets the requirements, and check whether the charging current of the battery pack during intermittent floating charging is within the required range. Check whether the charging current limit value of the battery pack is set correctly. Check whether the low voltage alarm and high voltage alarm settings of the battery pack are correct.
(4).Voltage requirements of lifepo4 battery pack for equal charging and floating charging operation
The intermittent charging voltage of lifepo4 battery pack is generally set to single battery: 3.60 ~ 3.76V. Measure the voltage of the battery pack and the terminal voltage of the single cell every month and compare it with the battery monitoring display, and repair the problem in time.
What aspects should be paid attention to in the maintenance of lifepo4 battery pack?
(1) Charge according to the standard time and procedure, even for the first three times;
(2).lifepo4 lithium battery pack should be stored in a cool, dry and safe environment;
(3). The activation of the lifepo4 lithium battery pack does not require any special method, and the lithium battery will be activated naturally in the normal use of the mobile phone. If you insist on using the circulating “first three 12-hour long charge activation” method, it won’t actually work.
(4) Avoid placing the lifepo4 lithium battery near heat sources, open flames, flammable and explosive gases, and liquids, which may cause battery leakage, heat generation, smoke, fire and explosion.
(5). If the lifepo4 lithium battery needs to be stored for a long time (more than one month), it is recommended to charge it to 40%-60%, and the battery needs to be recharged for 1-2 hours every month during the storage time.
The above are the precautions for the maintenance of lifepo4 lithium battery pack. In addition to the manufacturer must recognize and prevent the possible safety risks caused by the use of lithium batteries, the general consumer also has the responsibility. Injury caused by accident of lithium battery pack.
