摘要： A battery boost apparatus is described. The battery boost apparatus monitors that amount of voltage in the vehicle battery and the current flowing to the vehicle battery to determine an existence of a fault condition. If a fault condition exists, a vehicle battery is cutoff from the boost battery and the charge of the boost battery is maintained until the fault condition is remedied.

摘要： A housing assembly for a power edger that includes a housing and a door that is coupled to the housing and movable between an open position and a closed position. When positioned in the closed position, labyrinth seal members that are formed onto the housing and the door engage one another to form a labyrinth seal that inhibits dirt and debris from being expelled from the housing assembly. The housing assembly also includes a guard for shrouding a rotating blade. The guard includes a confronting portion having a leading end and a trailing end. The confronting portion is defined by an increasing radius relative to the rotary axis of the blade.

摘要： A battery charging system enables rapid recharging of a working battery without immediate access to ac power and without the need for current limit and/or overvoltage protection. The battery charging system makes use of a charging battery having a number of cells that is greater than the number of cells in the working battery. The charging battery produces a charging current that is proportional to the difference in the number of cells in each battery. In this manner, the battery recharging system is capable of rapidly recharging the working battery. The number of cells in the charging battery is selected, however, such that the series voltage of the charging battery cells is less than or equal to the maximum rated voltage of the working battery. Thus, the voltage of the charging battery is greater than the operating voltage of the working battery but less than or equal to the maximum voltage rating of the working battery. As a result, the charging battery is generally incapable of overcharging the working battery, and therefore does not require current limit and/or overvoltage protection circuitry.
摘要翻译：电池充电系统能够快速地对工作电池进行充电，而不需要立即访问交流电，并且不需要电流限制和/或过电压保护。电池充电系统利用具有大于工作电池中的电池数量的多个电池的充电电池。充电电池产生与每个电池中的电池数量差异成比例的充电电流。以这种方式，电池充电系统能够对工作电池进行快速充电。然而，选择充电电池中的电池数量，使得充电电池单元的串联电压小于或等于工作电池的最大额定电压。因此，充电电池的电压大于工作电池的工作电压，但小于或等于工作电池的最大额定电压。结果，充电电池通常不能对工作电池过度充电，因此不需要限流和/或过电压保护电路。
