摘要：
A battery pack system module may include a module bypass switch for allowing charge current to bypass the battery pack system module. The module bypass switch may be activated to divert charging current from the battery pack system module to other battery pack system modules. The charging current may be diverted to bring other battery pack system modules into balance with the battery pack system module. That is, to bring the state of charge of all battery pack system modules into coarse balance. When the module bypass switch is activated, charging current through the module bypass switch may be monitored by a current sensing device such as a current sensing resistor. A microprocessor may receive information about the bypass current level and use the information to determine when to de-activate the module bypass switch. Sensing current through a module bypass switch allows more accurate and quicker inter-module balancing.
摘要（中）：
电池组系统模块可以包括用于允许充电电流绕过电池组系统模块的模块旁路开关。 可以激活模块旁路开关，以将来自电池组系统模块的充电电流转移到其他电池组系统模块。 可以转移充电电流以使其他电池组系统模块与电池组系统模块平衡。 也就是说，使所有电池组系统模块的充电状态变得平衡。 当模块旁路开关被激活时，通过模块旁路开关的充电电流可以由诸如电流感测电阻器的电流感测装置监视。 微处理器可以接收关于旁路电流电平的信息，并使用该信息来确定何时去激活模块旁路开关。 通过模块旁路开关感应电流可实现更准确和更快速的模块间平衡。
