A vehicle, system, and method of operating a battery having a plurality of modules, each module having a plurality of strings. The vehicle includes a battery. The processor operates the plurality of modules in a first stage of an operating mode, calculates a model predicted path vector for the first stage based on a time for reducing a difference between states of charge of the plurality of strings, selects between the model predicted path vector and a default path vector based on an operating parameter of the battery, and transmits the selected path vector to the plurality of modules. And switching operation of the plurality of modules from the first phase to the second phase using a selected one of the model predicted path vector and the default path vector. 一种操作具有多个模块的电池的车辆、系统和方法，每个模块具有多个串。车辆包括电池。处理器在操作模式的第一阶段操作多个模块，基于一时间来计算第一阶段的模型预测路径向量，用于减小多个串的充电状态之间的差异，基于电池的操作参数在模型预测路径向量和默认路径向量之间进行选择，并且使用模型预测路径向量和默认路径向量中所选择的一个将多个模块的操作从第一阶段切换到第二阶段。
