Rate pipe enters OFF state or high impedance status, makes circuit for big damping；When battery module is connected completion or battery with battery
Module needs to start to work when high current pattern, and power tube enters fully on state or small impedance state, hinders circuit
Buddhist nun is small damping.
Alternatively, the adjustment module includes a power tube, a resistance in parallel between the source electrode of the power tube and drain electrode, when
When installation or removal are needed between battery module and battery, power tube is entered into OFF state, makes circuit for big damping；Work as battery
Module, which is connected completion or battery module with battery, to be needed to start to work when high current pattern, and power tube enters fully on shape
State, it is small damping to make circuit.
The protection circuit of foregoing invention, including battery module and battery, it is characterised in that：In the input of the battery module
There are one adjustment modules for connection before capacitance.
Further, the adjustment module is a variable impedance.
Alternatively, the adjustment module is a power tube.
Further, a resistance in parallel between the source electrode of the power tube and drain electrode.
The present invention before the input capacitance of the battery module by adding in an adjustment module, when battery module and electricity
When installation or removal are needed between pond, adjustment module is adjusted to big impedance state so that " battery-battery module " loop damping
It is sufficiently large, it is ensured that when battery module is connected with charged battery, " battery-battery module " circuit will not form strong vibration,
Voltage is without overshoot or without too big overshoot in the input capacitance of battery module.When battery module is connected completion or electricity with battery
Pond module needs to start to work when high current pattern, adjustment module is adjusted to minimum impedance so that " battery-battery module "
Loop damping is sufficiently small so that the normal work of battery module is unaffected.
Method of the present invention can also be applied to the installation and removal of other species battery modules.
Beneficial effects of the present invention：When ensuring installation and removal, battery module and the possible repeatedly irregular contact of battery, all
It will not cause to vibrate in " battery-battery module " circuit so that battery module voltages will not overshoot, and there will not be in circuit big
Current peak.It is so that safe when battery module mounts and dismounts；When battery module high current works, in " battery-electricity
Pond module " circuit does not introduce extra pressure drop, it is ensured that battery module can be worked normally in high current pattern.
