摘要： A battery pack can include one or more battery cells, current blocking transistors and a battery management system. The disclosed implementations handle over-currents drawn from the battery cells that cause unstable operation of the battery management system. The over-currents are handled without causing an undesired drop in voltage output from the battery cells. The disclosed implementations can handle over-currents even if the over-currents cause the battery management system supply voltage to drop below a minimum operating voltage level for a certain period of time. The disclosed implementations use current blocking transistors that can be configured to block current flow and ensure safe operation of the battery cells in cases where the current drawn from the battery cells would be sufficiently high for a sufficiently long period of time to cause damage to the battery cells.

摘要： In one implementation, a method for charging a battery system is provided. The method includes enabling determining if a charger is coupled to a battery system, the battery system including one or more cells and a charge enable transistor. The method also includes enabling determining if a voltage level of the cells is less than a predetermined first low voltage level. If the voltage level of the cells is less than the predetermined first low voltage level, enabling charging of the cells at a reduced rate including adjusting a voltage applied to the charge transistor gate terminal to regulate a voltage seen by the charger to a level that is less than a predetermined second voltage level. Additionally, when the voltage of the cells reaches the predetermined first low voltage level, the method includes substantially fully enabling the charge transistor to allow for charging at full rate by the charger.
摘要翻译：在一个实施方式中，提供了一种用于对电池系统充电的方法。该方法包括确定充电器是否耦合到电池系统，该电池系统包括一个或多个单元和电荷使能晶体管。该方法还包括能够确定单元的电压电平是否小于预定的第一低电压电平。如果单元的电压电平小于预定的第一低电压电平，则可以以降低的速率对单元进行充电，包括调整施加到充电晶体管栅极端子的电压，以将充电器所看到的电压调节到等于小于预定的第二电压电平。此外，当电池的电压达到预定的第一低电压电平时，该方法包括基本上完全使得充电晶体管允许充电器以全速充电。
