Battery Management System
The energy storage system is equipped with a complete battery management system, using a secondary management architecture and secondary software protection, including module level and battery cluster level, to achieve comprehensive control, management and protection of the battery system and ensure the safe and stable operation of the battery system.
When a single battery cabinet cannot meet the needs, multiple battery cabinets can be connected in parallel to form a battery system with a larger capacity, then the battery management system can be upgraded to a three-level management architecture and three-level software protection according to the needs of use, from the stack level to the cluster level to the module level, to achieve comprehensive control, management and protection of the battery system and ensure the safe and stable operation of the battery system.

Precautions
Safety precautions
Be sure to have professional electrical personnel or trained technicians to operate.
Make sure the high voltage power switch is disconnected during installation.
Please check the material carefully before installation, if there is any missing or damaged, please do not install dangerously.
Insulating gloves must be worn during installation, and the outside of metal tools must be tightly wrapped with insulating tape before use.
It is strictly forbidden to touch the total positive and negative of the battery pack at the same time during installation to avoid injury to people with high voltage.
Non-professionals are prohibited from disassembling the module shell, let alone touching the internal circuit board, so as not to cause electric shock accidents.
Without confirmation by the manufacturer's technicians, it is forbidden to modify or use this system on other projects to avoid serious accidents
Safe Use Guidelines
Safeguard measures should be provided for the safe and reliable operation environment of the battery system.
The power should not be greater than the rated power when in use, and the system should be kept away from fire, heat and water sources during use, and if the battery leaks or emits a peculiar smell, it should be stopped immediately, and the relevant personnel should be notified in time to deal with it.
The battery system is fully charged and fully discharged every six months, and it is recommended to charge and discharge the rate of 0.5C, and make detailed records.
Before the energy storage battery is stored for a long time and runs, the battery system must be safely inspected to avoid equipment damage or system safety problems caused by loose connections, water vapor condensation, rust or mold.
Disclaimer of Liability
The specification is for reference only, please consult the company for any matters not mentioned in this specification, and the company will not notify you when the version of this specification is updated. Please refer to the signed technical agreement for the specific parameters of the system at the time of delivery.
