Abstract

A method for extending the time a battery-operated electrical generator may operate by recharging the battery, at the same time it is being used as a power source, by using a portion of the electrical output to operate an alternator to produce low current and low voltage electrical power to recharge the battery, while supplementing from another source, including solar or wind, the power used to operate the alternator.

Claims

1. A method for extending the time a DC battery operated portable generator may operate by recharging the battery, at the same time it is being used as a power source, by converting its output to AC power first to handle the system load and next to operate an alternator system to produce low current and low voltage DC power, and to use the DC power for that purpose by connecting the alternator to the DC battery, while supplementing from another source, including solar or wind, the power used to operate the alternator.
