An energy storage backup system 5 for a vehicle comprises a primary energy storage means 30 for supplying energy to one or more primary vehicle loads 10, a secondary energy storage means 40 for supplying energy to one or more secondary vehicle loads 20 and a switch 60 in series between the primary and secondary storage means outputs. If the switch is in a closed position, both the primary storage means and the secondary storage means are connected to both the primary vehicle loads and secondary vehicle loads. If the switch is in an open position, the secondary storage means output is isolated from the primary storage means output, and the secondary storage means supplies energy only to the secondary vehicle loads. The energy storage means may be a secondary battery, super capacitor, ultra-capacitor, or fuel cell device. A DC/DC converter 50 may be provided to convert a high voltage from the secondary battery to 12v, suitable for charging the primary battery. A measurement means S1 may be a voltage or current measurement device or sensor. A control means 80 may be provided to control the switching of the switch dependent upon the value of the measurement means.
