A need was felt for an alternating current power box that supplies in excess of 100 amps at 120 VAC, had the inverter thermally conducting to the toolbox for additional heat dissipation and an isolator circuit.
The use of portable power inverters is known in the prior art. For example, U.S. Pat. No. 6,596,941 to Tripoli discloses AC electrical power delivery system for a pickup truck bed utility box for an AC electrical power delivery system for installation into a utility box attached to the bed of a pickup truck. This system delivers AC electrical power for operating light-duty equipment including power hand tools and electrical equipment to an included AC outlet connectable to a side wall of the utility box.

In operation it can be seen that the device contains the battery consisting of one or more 12 VDC batteries connected in the parallel circuit. The battery in turn is electrically connected to the inverter which converts 12 VDC input current into 120 VAC output current. This 120 VAC output is electrically connected to one or more receptacles mounted so as to be accessible from the exterior of the truck box. The user would connect the standard electric extension cord or device such as the electric drill or circular saw directly to the receptacle. Power would be instantly available. These external receptacles are ground fault protected to guard against electric shock to the user. The inverter also contains the number of safety related devices such as the low voltage alarm and electrical shutoff which would prompt the user to recharge the battery. The battery is recharged through electrical connections made to the existing engine alternator or to the supplemental alternator installed for the exclusive purpose of recharging this battery. Recharging occurs during normal driving of the vehicle or by idling the engine if needed. The charge state of the battery is assessed by the charging circuit. The charging circuit controls the charging current flow from the alternator according to the special algorithm in order to maximize battery storage capacity and condition while avoiding charging profiles which would be detrimental to battery life.
The device contains the battery pack consisting of one or more 12 VDC batteries of 100 Ahr capacity or greater connected in the parallel circuit. The battery pack in turn is electrically connected to the inverter which converts 12 VDC input current into 120 VAC output current. This 120 VAC output is electrically connected to one or more receptacles positioned so as to be accessible from the exterior of the enclosure. With the vehicle engine off, the user would connect the standard electric extension cord or device such as the electric-drill or circular saw directly to the exterior receptacle. Power would be instantly available. These external accessible receptacles are ground fault protected to guard against electric shock to the user. The inverter contains the low voltage disconnect that prevents the batteries from being discharged below a predetermined point by shutting off all AC power loads. This protects the construction, chemistry and service life of the batteries and insures that there is ample power to restart the vehicle engine. The audible low voltage alarm prompts the user to start the engine to recharge the battery pack. The battery pack is recharged through electrical connections made to the engine alternator or to the supplemental alternator installed for the exclusive purpose of recharging this pack. Recharging occurs during normal driving of the vehicle or by idling the engine if needed. The charge state of the battery pack is assessed by the voltage regulator. The voltage regulator controls the charging current flow from the alternator according to the special algorithm in order to maximize battery storage capacity and condition while avoiding charging profiles which would be detrimental to battery life. This charging profile also minimizes out gassing of the batteries which in all embodiments are vented to the exterior of the enclosure and or vehicle to avoid corrosion.
While the preferred embodiment of the high capacity mobile electric power source has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present embodiment of the invention. For example, any suitable sturdy toolbox material may be used instead of the stainless steel described.
Therefore, the foregoing is considered as illustrative only of the principles of the embodiment of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the embodiment of the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the embodiment of the invention.
