摘要
电池动力输出的持久性和稳定性,会影响大型新能源电动船舶的航行状态,因此,研究一种电池快速充电控制方法。结合实际充放电数据以及循环工况拟合结果,构建大型新能源电动船舶电池等效电路,分析电池的运行状态以及输出情况;通过确定电池快速充电控制的目标函数和约束条件,将目标函数输入模糊控制器中,分析目标函数对于电池电压的影响,在模糊规则清晰化处理后计算目标函数。通过改进布谷鸟算法进行计算结果寻优,获取最佳的控制结果。测试结果显示,在瞬态响应和负载动态响应2种运行工况下,该方法可以有效完成电池充电控制,使充电输出电压最大程度地接近理想输出电压,保证电流处于允许的持续充电最大电流范围内。
The durability and stability of battery power output can affect the navigation status of large new energy electric ships.Therefore,a fast charging control method for batteries was studied.Based on actual charging and discharging data and fitting results of cycle conditions,construct an equivalent circuit for large new energy electric ship batteries,analyze the operating status and output of the batteries;By determining the objective function and constraint conditions for fast battery charging control,the objective function is input into a fuzzy controller to analyze its impact on battery voltage.After clarifying the fuzzy rules,the objective function is calculated.By improving the cuckoo algorithm to optimize the calculation results and obtain the best control results.The test results show that under both transient response and load dynamic response operating conditions,this method can effectively complete battery charging control,making the charging output voltage as close as possible to the ideal output voltage,ensuring that the current is within the allowable maximum continuous charging current range.
