Abstract:
A battery charger is described for one or more rechargeable batteries. The charger derives its power from a DC power source such as another battery, and produces a pulsed recharging current that has a periodic variable frequency pulse. The charger also permits higher voltage charging current to be achieved than the initial voltage of the DC power source, and monitors both the power source and the batteries being recharged to avoid depletion of the power source or over charging of the batteries.
