The invention discloses a flexible extensible vehicle-mounted energy management method and system, which adopts a direct current architecture system and is mainly composed of three parts, namely a bidirectional energy controller, an energy storage battery pack and a system controller. The energy storage battery pack is composed of a battery pack and a battery management system, and the energy storage battery pack and the bidirectional energy controller form an energy unit. The energy units are designed in a modularized mode, all the energy units work in parallel, and the multiple energy units working in parallel are redundant to one another. The system supports adaptive parallel current sharing control and master-slave current sharing control. When a communication network is normal, parallel current sharing control of multiple energy units can be performed through master-slave control; when a communication network fails, the system is automatically switched to an adaptive current sharing control mode, and the system is high in stability and reliability. Different system design requirements can be met by adjusting the number of the energy units, and the system has high expandability, portability and reliability.
本发明公开了一种柔性可扩展车载能量管理方法及系统,采用直流架构体系,主要由双向能量控制器、储能电池包、系统控制器三部分组成。储能电池包由电池组和电池管理系统组成,储能电池包与双向能量控制器构成能量单元。能量单元采用模块化设计,各能量单元并联工作,多个并联工作的能量单元互为冗余。系统支持自适应并联均流控制、主从均流控制。通讯网络正常时,可以通过主从控制进行多能量单元的并联均流控制;通讯网络故障时,系统自动切换为自适应均流控制模式,系统稳定性、可靠性高。本发明通过调整能量单元数量即可满足不同系统设计需求,具有很强的可扩展性、可移植性,且可靠性强。
