Computer programmed battery charge control system
A computer programmed battery charge control system is described responsive to charge and discharge conditions, and including; at least one shunt passing all current from the battery to a load and between the battery and to a charger, there being a first relay switch the charge ON and OFF from an external power source, a current sense means in circuit with opposite ends of the shunt for producing a signal having a positive value per ampere charge and discharge, a polarity sense means in circuit with the shunt for producing a signal determining charge or discharge, a voltage sense means in circuit from the battery for producing a voltage signal equivalent to a computer reference voltage, an awake means in circuit with the signal from the current sense means for producing an awake signal to a second relay switch when the battery is less than at fully charged, and a computer having means therein in circuit with and responsive to the voltage sense means for sensing voltage proportionate to the battery voltage and comparing it to the computer reference voltage, having means therein including internal memory means in circuit with and responsive to the current sense means for sensing voltage proportionate to the current flow and storing the same as battery charge capacity remaining data, having means therein in circuit with an responsive to the polarity sense means for sensing direction of current flow through the shunt, and having means therein responsive to the voltage means, current means and polarity means and to the capacity remaining data in the memory means and programmed for producing a signal to the awake means for energizing and switching the first relay switch ON when the capacity remaining is less than at fully charged.
