BATTERY CHARGERS FOR SECONDARY CELLS OR BATTERIES, WHICH CONTROL THE THERMO RESPONSE OF THE CHARGE ACCEPTOR

摘要

A battery charging system has a effective pure DC power source charging at least one secondary charge acceptor utilizing an aqueous electrolyte. The applied effective voltage is equal to or slightly greater than the full charge level of said acceptor cell. An impedance/resistance is coupled between the charging means and the secondary charge acceptor cell. The impedance/resistance is a value which reduces any AC component out of the secondary cell to no more than 5% of the total voltage out in order to reduce the counterelectromotive force responsive to the applied voltage. The impedance/resistance is a value which is selected to set the capacitive reactance of the acceptor cell and the inductance reactance of the charging means at levels which reduce the counterelectromotive force of the acceptor cell throughout the full charge cycle in order to produce said cooling affect.
