Please tell us the   details of the power plant so that we can give you a feasible solution

 

Design advantage(Battery Energy Storage Solution):

 

1. Comprehensively real-time monitoring of safety risk points such as cell, connector, busbar and electrical parts

2. Design of special channel for thermal runaway of the cell, so that the eruption heat does not affect the rest of the cell;

3. Module core insulation design, so that each cell independent temperature control. In extreme cases, does not affect the adjacent cell safety and reliability

4. Liquid cooling module operates efficiently in extreme cases such as thermal runaway, quickly taking away heat;

5. The battery module is insulated and voltage resistant for long-term use.

6. High pressure box arc extinguishing design, effectively avoid the safety problems caused by pulling arc in extreme cases

7. The fire protection system can penetrate into each battery module to ensure the safety of the entire cabinet and minimize the damage in case of fire.

 

Product features(Battery Energy Storage Solution): Low energy consumption, long life, high consistency, high stability.


Application scenarios: photovoltaic power plants, wind power stations, power grid sites, industrial manufacturing plants, etc.


The Battery Energy Storage Solution can be customized according to the specific needs of customers, please contact us, we will be happy to provide you with Battery Energy Storage Solution.
