the delay time is reached. The BMS enters the charging over-current protection, and the charging
device cannot charge the battery.
After charging over-current protection occurs, the BMS will automatically delay recovery and
re-detect the external charger current. Discharge can also release the charge over-current
protection.
● Discharge over-current protection and recovery: When the discharge current exceeds
the discharge over-current protection setting value, and the delay time is reached. The BMS
enters the discharge over-current protection, and the load cannot charge the battery.
After discharge over-current protection occurs, the BMS will automatically delay recovery
and re-detect the external load current. Charging can also release the discharge over-current
protection.

VIII. Lithium battery management requirements
Because lithium is a metal that is particularly prone to chemical reactions, it is
easy to extend and burn, so if it is not handled in accordance with regulations during
PRODUCT MANUAL OF LITHIUM IRON PHOSPHATE BATTERY FOR COMMUNICATION
17

PRODUCT MANUAL OF LITHIUM IRON PHOSPHATE BATTERY FOR COMMUNICATION
18
packaging, transportation, and storage, it may cause serious accidents-combustion and
explosion.
In order to prevent casualties and property losses caused by improper handling of lithium
batteries in daily life, the following requirements are imposed on lithium battery management:
1. Basic requirements for battery warehouse management:
Due to the characteristics of lithium batteries, high temperature and humidity will accelerate
the self-discharge of the battery. It is recommended that the battery without opening the package
should be stored in a clean, dry and ventilated warehouse with an ambient temperature of -5℃～
35℃and a relative humidity of not more than 90%. Inside, the warehouse should not contain
corrosive gas.
Humidity requirements: effectively control the humidity of the warehouse to avoid extreme
humidity (relative humidity higher than 90%) for a long time.
Lithium battery warehouses should be physically separated by brick walls. The warehouses
must be enclosed, explosion-proof or other corresponding safety electrical lighting equipment.
The place where the battery is stored should be equipped with sufficient types of fire-fighting
equipments (such as carbon dioxide, dry powder fire extinguisher, fire hose, fire-fighting
sandbox) and ensure that it is in good condition. It is recommended to install an automatic rain
sprinkler fire extinguishing system if possible. It cannot be placed in the same warehouse with
flammable materials (such as packaging materials, cartons, cartons, etc.), and a separate
warehouse is recommended.
Where there are lithium batteries, there must be some illegal regulations such as prohibiting
smoking.
The battery pack should be far away from fire and heat sources, and operations that may
cause fires are not allowed in the warehouse or site where the battery is stored.
2. Good battery storage requirements:
The battery should be stored in a well-ventilated, dry and cool place. High temperature and
high humidity may damage the battery performance or corrode the battery surface.
The battery packing box should not be stacked higher than the arrival height when the
materials are received, otherwise the batteries in the bottom box may be deformed and liquid
leakage may occur.
The battery should not be stored or displayed in direct sunlight or places exposed to rain. If
the battery is drenched, the insulation resistance will decrease, and self-discharge and rust may
occur. A rise in temperature may damage the battery.
Store and display the batteries in their original packaging to avoid random stacking of the
batteries after the packaging is removed, which may cause short circuits and damage to the
batteries.
Items that are likely to cause combustion or explosion when they come into contact with
each other and items with different fire fighting methods should be stored separately.
After the production is completed, when the surplus battery is returned to the warehouse,
the original packaging state (insulation) needs to be restored first and then stored.
3. Defective battery storage requirements
In case of serious defects such as leakage, bump damage, short circuit, etc. of defective
