动力梯次电池在储能系统中的应用

Application of Power Ladder Battery in Energy Storage System

以动力梯次电池为研究对象,采用系统集成的方式研究了梯次电池在储能系统中的应用。结果表明,动力梯次电池在容量降低到75%左右时,依然可以在储能系统中发挥作用。该类电池的一致性需求匹配对应BMS系统,系统运行后梯次电池的充放电效率达到95%左右,满足储能需求,实现了较高的应用价值。

Taking the power cascade battery as the research object, this paper studied the application of the cascade battery in the energy storage system by means of system integration. The results show that the power cascade battery can still play a role in the energy storage system when the capacity is reduced to about 75%. The consistency requirement of this type of battery matches the corresponding BMS system. After the system is operated, the charge and discharge efficiency of the cascade battery reaches about 95%, which meets the energy storage requirements and achieves high application value.
