SYSTEM AND METHOD FOR VEHICLE BASED UNINTERRUPTABLE POWER SUPPLY
First Claim
1. A vehicle-based uninterruptable power supply (UPS) system comprising:
- an energy storage system located on-board a vehicle and configured to generate DC power transferable to an external load;
an DC-AC inverter connected to the on-board energy storage system to receive the DC power therefrom and invert the DC power to an AC power useable by the external load;
a charging device located on-board the vehicle and connected to the on-board energy storage system to provide a recharging power thereto; and
a control system configured to;
determine one of a state-of-charge (SOC) and a voltage of the energy storage system; and
selectively operate the charging device to provide the recharging power to the energy storage system to maintain the one of the SOC and the voltage of the energy storage system within a pre-determined range.

Abstract
A system and method for controlling a vehicle-based source of uninterruptable power is disclosed. The vehicle-based UPS includes an energy storage system located on-board a vehicle and configured to generate DC power transferable to an external load, and an DC-AC inverter connected to the on-board energy storage system to receive the DC power therefrom and invert the DC power to an AC power useable by the external load. The vehicle-based UPS also includes a charging device located on-board the vehicle and connected to the on-board energy storage system to provide recharging power thereto and a control system. The control system is configured to determine one of a state-of-charge (SOC) and a voltage of the energy storage system and selectively operate the charging device to provide the recharging power to the energy storage system to maintain the SOC or voltage of the energy storage system within a pre-determined range.

16. A method for supplying uninterruptable power comprising:
-
detecting connection of an external load to an on-board energy storage system of a vehicle; providing power from the on-board energy storage system to the external load upon connection thereto; detecting one of a voltage and a state of charge (SOC) of the on-board energy storage system; and if the one of the voltage and the SOC of the on-board energy storage system is below a pre-determined threshold, then activating a charging unit connected to the on-board energy storage system to supply a recharging power thereto and maintain the one of the SOC and the voltage of the on-board energy storage system within a pre-determined range. - View Dependent Claims (17, 18, 19, 20)

21. A control system for controlling the supply of uninterruptable power from a vehicular on-board energy storage system to an external load, the control system programmed to:
-
detect connection of an external load to an on-board energy storage system of a vehicle; measure one of a voltage and a state of charge (SOC) of the on-board energy storage system upon connection of the external load; activate a charging device connected to the on-board energy storage system to supply a recharging power thereto if the one of the voltage and the SOC of the on-board energy storage system is outside a pre-determined range; and deactivate the charging device if the one of the voltage and the SOC of the on-board energy storage system is within the pre-determined range. - View Dependent Claims (22, 23, 24, 25, 26)
