The junction box (34) may be operatively connected to the first electric power storage device (30) by a first electric connection (36) having a first inductance, and operatively connected to the second electric power storage device (32) by a second electric connection (38) having a second inductance. The first inductance may be equal to the second inductance such that power source charging power from the junction box (34) is distributed equally to the first electric power storage device (30) and the second electric power storage device (32), and power source output power to the junction box (34) is drawn equally from the first electric power storage device (30) and the second electric power storage device (32).Charger System Charger Charger 42 44 40 46 48 Charger Charger 16- Plug Plug Battery Charger Charger Powered Receptacle Receptacle Electric Drive System 50 52 54- Contactor Contactor -56 Box Box 300 63 32 Power Junction Power Storage Box Storage 74 Device Device( 34 24V 62 Batteries 60 Inverter Co nrter s) Re ays24 BatteryrChillr 64" 66 80 24Wae Traction Power Pump Motor Drive Motor 82- 24V 18 6 70,Machine 18 6870 72 System DrveranHydraulic 84, 4 Pump(s) Machine FIG. 2 System
