The ports such as CTL and CO, its type and quantity and connected mode can be according to the species sums of battery core
Depending on amount, the present invention is without limitation.In addition, in the present embodiment, on protection circuit plate P also
Can be arranged as required to multiple filter capacitor C1, C2, C3, C4 and multiple resistance R1, R2,
The functions such as voltage detecting, input and output of the parts such as R3, R4 to realize battery protection chip U1.
Wherein, as shown in figure 3, in the present embodiment, in order to control the controlled fusing work(of safeties
Can, the MOS on protection circuit plate P is provided between the 3rd pin 3 and battery protection chip U1
Pipe Q1.Specifically it is connected on battery protection chip U1 CO ends.The metal-oxide-semiconductor is in the art
Well-known components are not done excessively repeat herein.Wherein, cut-off shape is located under the metal-oxide-semiconductor normal operating conditions
State, and when the problems such as battery being overcharged, battery protection chip U1 can export corresponding to metal-oxide-semiconductor
During electric signal, for example, the high level at CO ends is conjugated into low level, so that metal-oxide-semiconductor is in
Conducting state, can then realize the power supply to heating module 6, so that the insurance of safeties is melted
Silk 5 fuses under the heat effect of heating module 6, so as to realize controllable fuse function.
The operation principle of the battery modules is explained in detail below.
In normal work, Multifunctional safety silk SCF is failure to actuate, the first pin 1 and second pin 2
In connection conducting state.
Overcurrent protection：When the electric current passed through in circuit exceedes safeties SCF one section of rated current
After time, the insurance fuse 5 between the first pin 1 and second pin 2 fuses, and circuit disconnects, so that
Ensure cell safety.
Over-temperature protection：When exception occurs in battery core B, and battery temperature is raised, at this moment, it is close to battery core B
Safeties SCF insulating heat-conductive substrate 4 can sense battery core B temperature and be delivered to first
Insurance fuse 5 between pin 1 and second pin 2, after specification value, insurance fuse 5 fuses,
Circuit disconnects, so as to ensure cell safety.
Overcharge protection：When being charged to battery core, battery protection chip U1 monitors battery core B voltage,
When there is voltage to exceed battery protection chip U1 protection value, battery protection chip U1 can be CO ends
High level be changed into low level, now metal-oxide-semiconductor is turned on, so can be directly battery core B EB+ electricity
Pressure is added on the heating module 6 inside safeties SCF, so, by the persistent fever of heating module 6,
And insurance fuse 5 is fused completely by the heat conduction of insulating heat-conductive substrate 4, make battery core and external circuit
Cut-out, so that battery core does not continue to charging so that battery core does not continue to deteriorate, so as to protect electricity
Pond safety.
Other protections：Due to CO height can be controlled by the setting in battery protection chip U1
Level changes, so as to control safeties SCF fusing, can so expand the application of battery, can be with
Definition needs the function that battery circuit disconnects.Replaced as the serious unbalanced, battery of battery is disassembled restructuring,
Battery capacity is low, can start control end safety fuse SCF, so as to ensure that battery core is used
Safety.
