The invention discloses a control method of a new energy ship battery power system, and the method comprises the steps: monitoring the health state of each battery cluster in real time through a battery management system (BMS), transmitting health information to a power management system (PMS), obtaining a risk value S according to the product of a fault frequency and a fault consequence level, and carrying out the processing according to different risk values S; when it is judged that there is a battery cluster which must be replaced at present, a power management system (PMS) needs to adjust the real-time distribution power of each battery cluster in a current battery power system, and all the power borne by the fault battery cluster is transferred to other battery clusters in a power transfer mode.
本发明公开了一种该新能源船舶电池动力系统的控制方法,通过电池管理系统BMS实时监测各个电池簇的健康状态,并将健康信息传输给功率管理系统PMS,对故障频率与故障后果等级的乘积得到风险值S,按不同风险值S进行处理;当判定当前有必须更换的电池簇后,功率管理系统PMS需要调整当前电池动力系统中各个电池簇的实时分配功率,通过功率转移的方式,将故障电池簇所负担的全部功率转移到其他电池簇。
