The invention belongs to the technical field of lithium batteries, and provides a parallel and serial lithium battery control system, which comprises a receiving module used for receiving operation data of an agricultural vehicle and obtaining state parameters of each lithium battery; the controller is used for predicting an operation mode required by the agricultural vehicle according to the operation data, and the operation mode is a high-power mode or a long-endurance mode; when the operation mode is a high-power mode, further determining a corresponding target operation voltage, and screening out a plurality of target lithium batteries according to the target operation voltage and the state parameters of the lithium battery modules; and the series-parallel connection switching module is used for switching each target lithium battery into a series connection state. The operation mode can be accurately predicted according to the vehicle operation data, so that the series connection mode or the parallel connection mode of the lithium battery can be flexibly adjusted according to high-power operation or long-endurance operation, power supply matched with the operation mode is guaranteed, the requirements of different scenes are met, and the agricultural operation efficiency is improved.

    本发明属于锂电池技术领域,提供了可并可串锂电控制系统,包括接收模块,用接收农业车辆的作业数据,以及获取各锂电池的状态参数;控制器,用于根据作业数据预测得出该农业车辆接下来需要的作业模式,作业模式为高功率模式或长续航模式;在作业模式为高功率模式时,进一步确定对应的目标作业电压,根据目标作业电压和各锂电池模块的状态参数筛选得出若干目标锂电池;串并联切换模块,用于将各目标锂电池切换为串联状态。本发明能够依据车辆作业数据精准预测作业模式,从而实现依据高功率作业或长续航作业而灵活调整锂电池的串联模式或并联模式,以保障与作业模式适配的动力供应,满足不同场景需求,提升农业作业效率。
