ABSTRACT:
An automotive battery charger or other electrical device which draws substantial amounts of power is provided with a variable delay mechanism which prevents turn on of the device when power is applied. The duration of the delay is determined by a random or pseudorandom number generator, so that a plurality of different electrical devices will, in effect, be turned on at random times following application of power. The maximum turn on delay could be conveniently limited to a specific period of time, so that critical operating times of the device, such as the charging cycle of a battery charger, are not shortened excessively.
