ABSTRACT:
A load and battery charge device in a vehicle electrical system controllably disconnects a battery or other stored energy source from the electrical system when the battery state causes the system voltage to operate below a desired threshold. The device filters generator ripple voltage during batteryless operation to maintain an acceptable ripple voltage. The load and battery control device operates to recharge the battery that is disconnected from the vehicle electrical system at a controlled voltage independent of the vehicle electrical system voltage. The load and battery control device controls the rate of battery recharge so as to avoid overburdening the vehicle electrical system and then reconnects the battery to the vehicle electrical system once the battery voltage has reached a minimum threshold.
