    • A cordless electric mower having an energy management system that allows a user to operate the cutting blade motor of the mower at a wide range of user selected speeds. The mower is provided with a user adjustable throttle control which, when in the wide-open position allows the cutting blade motor to be rotated at a maximum, predetermined speed. When the throttle is set to some lesser speed, the system automatically implements a speed foldback routine whenever the mower encounters heavy loading which would result in an undesirably high current draw on the battery. When the speed foldback routine is implemented, the system limits the maximum amount of current that can be drawn by the motor until the excessive loading condition has been removed. Once the excessive loading condition has been removed, the speed foldback routine automatically increases the speed of the blade motor back up to almost the originally selected speed. This greatly improves the operating efficiency of the mower and thereby significantly extends the available operating time of the mower on a single charge. The state-of-charge of the battery is also monitored continuously during operation. An LED display provides the user with an indication of the approximate battery charge remaining.
    • 一种具有能量管理系统的无绳电动割草机，其允许用户以宽范围的用户选择的速度操作割草机的切割刀马达。 割草机设置有用户可调节的节气门控制器，当处于大开位置时，刀片电动机可以以最大的预定速度旋转。 当节气门被设定为一些较小的速度时，系统会在割草机遇到大量负载时自动实施速度折返程序，这将导致电池不期望的高电流消耗。 当执行速度折返程序时，系统会限制电机可以吸收的最大电流量，直到超载条件已被移除。 一旦超载条件已经消除，速度折返程序自动将刀片电机的速度提高到几乎最初选定的速度。 这大大提高了割草机的操作效率，从而显着地延长了割草机在单次充电中的可用操作时间。 电池的运行状态也在运行期间连续监测。 LED显示屏为用户提供剩余的大约电池电量的指示。

    • A dual-mode system for inexpensively operating electrically powered double-insulated devices (12), such as hand-held power tools and appliances. The system includes a cordless battery power module (14) that supplies the power and current demands of the device (12) in a cordless mode or a chopper module (21) that supplies the necessary power and current demands in a physical envelope commensurate in size and interchangeable with that of the battery power module (14). The chopper module (21) is provided with a non-filtered high efficiency converter circuit that allows the chopper module (21) to generate the power and current required by the driven device (12). The inductance of the motor (11) for the driven device (12) is used to filter the output of the chopper module (21). Eliminating the output filter from the chopper module (16) significantly reduces the cost and size of the module (16). Additionally, the need for multiple battery packs and fast rechargers is minimized by the availability of a low-cost converter. The line power module (16) includes an EMI filter (15) for filtering AC or DC input power. The chopper module (21) chops the filtered voltage, providing a series of voltage pulses having a DC voltage level that is suitable for driving the motor (11).
