    • In an embodiment, an energy storage system includes one or more storage cells, charge/discharge circuitry, and charger wakeup circuitry. After the storage cells become depleted below an energy level threshold, the charge/discharge circuitry disconnects the storage cells from a main circuit associated with the storage system. The charger wakeup circuitry allows a limited amount of current to bypass the charge/discharge circuitry in order to present a current-limited voltage from the storage cells at the terminals. The voltage presented at the terminals is pulsed on and off when an external device is connected across the terminals. The voltage presented to the terminals is detected by the external device. After detecting the voltage, the external device performs an operation in response to detecting the condition.
    • 在一个实施例中,能量存储系统包括一个或多个存储单元,充电/放电电路和充电器唤醒电路。 在存储单元耗尽低于能量水平阈值之后,充电/放电电路将存储单元与与存储系统相关联的主电路断开。 充电器唤醒电路允许有限量的电流绕过充电/放电电路,以便在端子处存储来自存储单元的限流电压。 当外部设备连接在端子上时,端子上呈现的电压被脉冲打开和关闭。 通过外部设备检测端子电压。 在检测到电压之后,外部设备响应于检测到状况而进行操作。

    • Systems and methods of pre-charging battery cells that can pre-charge battery cells included in a plurality of series-connected battery modules. The systems and methods monitor a value of a pre-charge current provided to the series-connected battery modules, and monitor a voltage level of the battery cells within each battery module. The systems and methods switchingly interrupt the pre-charge current within each battery module once it has reached a predetermined threshold current value or the battery cells within the battery module have been charged to a UVP level, causing a flyback current to flow into the battery cells of each battery module that have not yet been charged to the UVP level. Once the battery cells within each battery module have been charged to the UVP level, the systems and methods can provide a full-charge current to the series-connected battery modules.
