摘要： An optically communicative battery management system includes a pack controller and one or more module controllers optically coupled to the pack controller. The module controllers may themselves be optically coupled together in series, and communication from an upstream module controller may be relayed through one or more downstream controllers en route to the pack controller. The pack controller may also send an optical signal that is used by the pack controller to determine whether any one or more of the battery modules is experiencing a safety fault, and the communication channel used to transmit that optical signal may, absent any safety faults, be used to multiplex message data to the module controllers.
摘要翻译：光学上可通信的电池管理系统包括电池组控制器和光学地耦合到电池组控制器的一个或多个模块控制器。模块控制器本身可以串联地光学耦合在一起，并且来自上游模块控制器的通信可以通过一个或多个下游控制器中继到途中到组件控制器。电池组控制器还可以发送由电池组控制器使用的光信号以确定电池模块中是否有任何一个或多个电池模块正在经历安全故障，并且用于发送该光信号的通信信道在没有任何安全故障的情况下，用于将消息数据复用到模块控制器。

摘要： There is described a method of balancing a multi-cell battery. An alignment distance for each cell of the multi-cell battery is determined. The alignment distance defines a change in charge quantity required to achieve a target alignment point, based on a current charge quantity of the cell. Based on the determined alignment distances, one or more unbalanced cells are identified. Each unbalanced cell is then balanced by adjusting its current charge quantity according to the alignment distances. In one embodiment, the target alignment point is a target state of charge. In another embodiment, the target alignment point is a target charge quantity.
摘要翻译：描述了平衡多单元电池的方法。确定多单元电池的每个单元的对准距离。对准距离基于电池的当前电荷量来限定实现目标对准点所需的电荷量的变化。基于确定的对准距离，识别一个或多个不平衡单元。通过根据对准距离调整其当前电荷量来平衡每个不平衡电池单元。在一个实施例中，目标对准点是目标充电状态。在另一个实施例中，目标对准点是目标电荷量。
