1. Choose the right lithium battery

     At this stage, lithium batteries are a good choice, especially lithium iron phosphate batteries, and in terms of stability, we must understand that we must mainly stable (which measures can be taken to prevent accidents) and secondary stability (how to occur in the accident occurring in the accident. After the better control and management danger), treat them separately. The stability of the lithium battery is one of the basically stability. Only by choosing a suitable lithium battery can we ensure the stability of the energy storage system. The raw material cell and production process of lithium batteries are the two major nodes of lithium batteries.

2. Ensure the orderly and stable integration of the battery module

For example, in the overall design, the modules and racks of the system need to meet relevant standards, such as the battery that meets the technical standards of UL1973 and IEC62619. The reason why the UL9540A standard certification is to pass this battery, which shows that our products have undergone rigorous tests, such as: various extreme events, simulation thermal output events, fire resistance, etc.

3. Perfect and stable BMS system

    The BMS system here, that is, the battery management system, which can protect the stability of the lithium battery. For over -charged, over -loading, etc., to ensure the stability of the lithium battery, the BMS needs to pass the IEC61508 standard certification, that is, electrical/electronics/programmable programming The functional stability standards of electronic stability related systems.

4. Lithium battery energy storage system compliance

      The lithium battery of the energy storage system is recommended to meet key stability standards such as IEC and UL. Especially during design, the lithium battery energy storage system is designed according to the stable requirements of the "grid integrated energy enhancement system in the IEC62933 part 2.

5. Fire fighting stable configuration

     Lithium batteries and other components need to be placed in a modular operation industrial cabinet for orderly isolation, and equipped with a sound fire prevention system and plan. Industrial cabinets have high fire resistance and can provide the required heat insulation functions. To reduce the auxiliary energy consumption to a greater extent, keep the battery at a specific temperature (usually at 20 ° C -23 ° C) to avoid excessive heat or cold.
