  • Patent number: 4246529
    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.

  • Patent number: 4237385
    Abstract: A power supply control system suitable for controlling and protecting batteries used in such systems by causing the automatic disconnection of the battery from a load when either the battery voltage has dropped to a preset level or when the load has open circuited. Disconnection of the load ensures that the battery does not undergo any further discharge (except self discharge) and the load can only be reconnected to the battery when a main supply (charging means) is reapplied and removed again or by use of additional circuitry from an external switch, and then only when load is present and battery voltage is above the preset level.
