The positive and negative anodes of the battery are electrically connected with builtin voltage test side VDD and ground terminal GND respectively;The inside is steady
The both ends of voltage capacitance C1 are electrically connected with external circuit voltage detecting end VCC and ground terminal GND respectively;The external circuit electric capacity of voltage regulation C2
Both ends be electrically connected respectively with current detecting end VM and ground terminal GND.
The utility model has the beneficial effects that solving current common batteries does not have the defect of safeguard protection, it can be greatly
The probability of happening of cell safety accident is reduced, life and property safety of people is protected.
Description of the drawings
Fig. 1 is the overall effect figure of the utility model.
Fig. 2 is the Structure explosion diagram of the utility model.
Fig. 3 is the circuit diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the utility model is a kind of battery with safety protection function.
As shown in Figures 2 and 3, the utility model includes battery 1, and the protection board 2 being mounted on 1 anode of battery fastens
The insulation rubber cushion 4 of protective cap 3 and pad between battery anode and protection board 2 on protection board 2.The protection board 2 wraps
Main control chip SDC6081 is included, the builtin voltage test side VDD in main control chip SDC6081 left ends is set, is detected with builtin voltage
External circuit voltage detecting the end VCC, ground terminal GND and internal electric capacity of voltage regulation C1 that end VDD is in series;It is arranged in main control chip
The current detecting end VM and external circuit electric capacity of voltage regulation C2 of SDC6081 right ends.The positive and negative anodes of the battery 1 respectively with builtin voltage
Test side VDD and ground terminal GND electrical connections;The both ends of the internal electric capacity of voltage regulation C1 respectively with external circuit voltage detecting end VCC
It is electrically connected with ground terminal GND;The both ends of the external circuit electric capacity of voltage regulation C2 are electrically connected with current detecting end VM and ground terminal GND respectively
It connects.
In normal state, main control chip SDC6081 is powered by battery, and the voltage of builtin voltage test side VDD is in
Between overcharged voltage value and overdischarge pressure value, the current value of current detecting end VM, which is less than, overcharges electric current and overdischarge stream.At this point, main
Switching transistor inside control chip SDC6081 is in Normal on state, and battery is charged and discharged process and freely converts.
During battery 1 is charged normal, when the voltage value of builtin voltage test side VDD is more than VCB values(I.e.
Overcharged voltage detected value)When, and hold time more than TCU values(I.e. overcharged voltage detects delay time), main control chip SDC6081
Internal switching transistor is switched to closed state, has cut off charge circuit, stops charging, and entire battery enters charging overvoltage
Guard mode;During battery 1 is charged normal, when the current value of current detecting end VM is more than ICOC(Overcharge
Over-current detection value)When, and hold time more than TCOC values(Overcharge over-current detection delay time), in main control chip SDC6081
The switching transistor in portion is switched to closed state, has cut off charge circuit, stops charging, and entire battery enters the galvanic electricity that charged
Guard mode.
In battery 1 carries out normal discharge, when discharge current is more than IOC values(Discharge over-current detection current value)
When, and hold time and (discharge over-current detection delay time more than TOC), the switching transistor inside main control chip SDC6081
It is switched to closed state, has cut off discharge loop, stops electric discharge, entire battery enters electric discharge overcurrent electric protection state.
Under normal charging condition, when the voltage value of current detecting end VM is less than or equal to VSIP values (i.e. short-circuit protection electricity
Pressure value)When, main control chip SDC6081 will (i.e. load short circuits detect delay time in TSIP)By its internal switch three in time
Pole pipe is switched to closed state, and entire battery is made to enter load short circuits guard mode.
When being charged to battery using charger, if accidentally that charger positive and negative anodes are reversed, main control chip SDC6081 inspections
After the reverse current for measuring the ends VM, its internal switching transistor is switched to closed state immediately, to cut off reverse charging
Circuit makes entire battery enter the reversed guard mode of charger.
