ABSTRACT:
The battery charger employs integrator means and current switch means in combination with a control circuit whereby the control circuit receives a synchronizing signal at the start of each cycle as determined by a cyclical supply or pulse generator as well as information about the state of the integrator means which is compared with the predetermined average current such information determining the required control signals for the integrator means and current switch means so as to maintain the value of the average charging current substantially constant throughout the charging time. Current sense means being provided to sense the current flow through battery and supply the integrator means with said sensed current.
