Abstract:
1. A system comprising: an input configured to connect to a power source providing an input voltage; a first output configured to connect to a load and to transfer power from the power source to the load; a connection mechanism coupled to the input and comprising a second output, the second output configured to couple to a battery, the connection mechanism configured to selectively couple the input to the second output to selectively provide current from the power source to the battery when the battery is coupled to the second output; and a processor, coupled to the connection mechanism, configured to regulate the selective coupling of the second output to the input to regulate a charging current supplied to the battery such that when the charging current is at a first level and the input voltage drops below a threshold voltage level, the processor will change the charging current to a second level that is lower than the first level.
