5. Apparatus for charging electrical storage battery means including direct current source means to provide said generally linear charging current;
- current controller means providing a central signal determine the rate of flow of current to said storage battery;
switch means connected in series between said direct current source means and said battery means and having signal input means to receive said control signal whereby said switch means is operated by said controller in response to said current flow rate to said battery to regulate rate of current flow to said battery modulator means to receive said control signal and supply an operating signal to cyclical wave generating means to selectively periodically interrupt said cyclical wave generating means. - View Dependent Claims (6, 7, 8, 9)
