摘要： An electricity storage device and a portable electric-powered tool. The device comprises at least a battery; at least a super capacitor, which has lower internal impedance, when fully charged, than that of the battery and connects the battery in parallel; and an output end for supplying the electricity. The super capacitor is the major power supply for the pulse current output; the battery is used for generating electricity to the super capacitor and is the secondary power supply for the pulse current output. The connection of the battery and the super capacitor does not need any converters or current-limiting resistors.

摘要： A lithium-ion battery protection method and device controls an externally connected circuit to charge/discharge a rechargeable battery so as to prevent the rechargeable battery from over charging/discharging. The lithium-ion-ion battery protection device includes an abnormality detection circuit, a light coupling circuit, a balancing circuit, and a recognition circuit. The abnormality detection circuit is to detect the voltage of the lithium-ion-ion battery and output a detection signal. The battery continues to charge/discharge if the signal is normal, and terminate to charge/discharge if the signal is abnormal. Then, the balancing circuit determines whether the detection signal is an overcharged signal, and if yes, the rechargeable battery is discharged accordingly. Meanwhile, the light coupling circuit adjusts an impedance of the light coupling circuit based on the detection signal so as to break the connection between the rechargeable battery and the externally connected circuit, and the recognition circuit outputs signal identifying location of the battery.
