如果更多的电力需求是间歇性，发动机的功率可补充电动机在电源时，需要更多的时间。
If demand for more power is intermittent, the power of the engine can be supplemented by an electric motor during times when more power is needed.
好的，电源组包括电动窗和电动锁，电功率表和电动天线。
Ok, the power package inclues power windows and locks, power meters and power antenna .
目前国内外电动车直流驱动功率变换器使储能电源输出电流从零到电机电枢电流高频脉动，不利于延长动力电池的使用寿命。
At present power converters of DC driving system make power supply outputs a high-frequency pulsating current, which is from zero to the armature current. This large ripple damages batteries.
对风机及电动机的电源电压、频率、功率，盘管规格，加湿器种类，空气过滤器形式及效率，配管口径及方向等有要求时请注明；
About the supply voltage, frequency, capacity factor of the fan and motor, specification of coil pipe, kinds of humidifier, form and efficiency of air filter, caliber and direction of pipe and etc.
对短时工作电动机最大功率的测量是困难的，要在标准电源、标准环境温度下的测量更加困难。
It's quite difficult to test the maximum power of the electric motor for short - time work, not to mention the measurements under standard voltage and temperature. Nowadays.
