SOLAR ENERGY OPERATED AUTOMATIC CHARGE DEVICE FOR ELECTRIC APPLIANCES

摘要

A charging device for accumulator-operated small electrical appliances, for example, electric dry-shavers, which are energized by rechargeable accumulators (24) which can be charged by means of a charging device (15) including solar cells (11). The charging device includes an energy buffer (20) which is connected parallel to the solar cells for buffering the solar energy when the charge capacity of the solar cells is below the charge current threshold of the accumulator. The buffered solar energy is supplied to the accumulator when a discharge current of the energy buffer exceeds the charge current threshold of the accumulator and flows until the discharge current falls below the charge current threshold.
