Abstract:
1. A battery charging coaction and output system with current limited power supply, comprising: a battery (BAT 101 ) capable of repeated charging and discharging; and an auxiliary power supply (PS 100 ) connected to supply charging current to the battery (BAT 101 ) and further connected to supply load current to the load, wherein said auxiliary power supply (PS 100 ) and battery (BAT 101 ) are thereby connected to selectively supply power to the load both individually and jointly, wherein an output current of the auxiliary power supply (PS 100 ) is limited, wherein a load current supplied to the load is a sum of the limited output current of the auxiliary power supply and a discharge output current of the battery, which varies dependent on the load such that: if the load current is smaller than a rated maximum output current of the auxiliary power supply (PS 100 ), the auxiliary power supply (PS 100 ) supplies all of the load current directly to the load, and further supplies a difference between the load current and the current limited output current to charge the battery (BAT 100 ); if the load current is larger than a rated maximum output current of the auxiliary power supply (PS 100 ), the auxiliary power supply (PS 100 ) supplies all of the current limited output current to the load and a difference between the load current and the current limited output current is supplied to the load by the battery (BAT 100 ), and wherein the auxiliary power supply (PS
