Abstract

Additional Smart Switch (ASS) is especially suitable for lighting power saving of existing buildings because its installation requires no wall damage and no rewiring. However, as a new device working in low light environment, it is a challenge for ASS to charge lithium battery with solar panels. This paper offers an alternate charging method in weak light conditions for ASS. Following this method, the chargeable battery will be charged efficiently by the way of continuous "electricity accumulating” and alternate “battery charging". Furthermore, this paper put forward a self-adaptive judgment method for determining the opening time of “battery charging". The alternate charging method provided by this paper has been validated through a series of experiments and applied to actual ASS products.
