How to activate the lithium-ion battery shield?

Lithium-ion battery shields use field-effect transistors as shielding components. In order to ensure that the battery will not be reconnected to the circuit when abnormal, the circuit is specially designed. The main point is that the power supply of the control section of the protection circuit is powered by the protection field effect tube, and the circuit will only work after the protection tube is normally turned on. Therefore, in the first use or after the protection has been presented, the power supply of the subsequent circuit is disconnected, and the circuit has no power supply, and the protection circuit cannot work. There is no output from the battery. At this time, only when the battery is connected to the charger, the charger is operated to supply power to the control circuit section of the protection circuit, and the control section receives electricity, the lithium-ion battery can be used normally. The essentials of activation of the lithium-ion battery shield: If the shield is activated due to current-limiting protection, it may be activated after the charge is activated and the load is completely disconnected, then the contest is relatively poor, but it can also be B- (battery negative) and P -(Discharge negative) Short-circuit and touch, the shield will be released. Remember not to carry a large load when short-circuiting and touch (like turning it and twisting it all the time), otherwise it will probably spark a lot of sparks. The basic reason is to cover. A large voltage difference is formed at both ends of the post-discharge MOS. A short-circuit touch resets the DS level of the discharge MOS directly to 0V, and now the shield is released. At this moment, not all lithium-ion battery shields have to be activated, but some shield ICs need to be activated, and this is the old IC method, the old IC method. This is why we want to do this in order to make the shield not work. Electrostatic discharge energy, so that lithium-ion batteries can be stored longer.
