【摘要】 本文在分析锂离子电池的充放电特性,建立电池模型的基础上,设计了相应的控制策略,根据系统的动态特性,探讨了锂电池储能装置中的能量管理控制系统的设计方法,搭建了硬件电路。通过控制双向变换器调制锂电池的充放电,使经过变换器的直流母线电压保持恒定,便于后续环节的配置。通过仿真与实验对锂电池储能装置的输出特性进行验证,证实了所设计的能量管理控制系统的有效性。实验结果表明,经过管理系统对电池充放电,使冲击大大减小,同时延长了电池的寿命。更多还原

【Abstract】 This paper analyzes the charging and discharging characteristic of lithium ion battery, builds common lithium battery model and corresponding control strategy is developed,based on the dynamic behavior of the system,discusses energy management controlling system design method of the lithium battery energy storage device,sets up the system simulation model,builds the hardware circuit.We modulate lithium battery charge-discharge status by controlling the bidirectional converter,that makes bus voltage of bi-directional DC/DC converter constant,facilitates subsequent configuration.It is the simulation and experiments for lithium battery energy storage device to verify the output characteristics,which is proved that the design of energy management for the control system is valid.Experimental results show that management system for battery charging and discharging,makes the impact greatly decreased,and extendeds the battery life.更多还原
