Lithium-ion battery protective board activation This is not all of the iron lithium-ion battery protection boards, just protecting ICs to be activated, and this is old IC method, old IC method, this is to do this is In order to make the protective board do not work, reduce the electrostatic discharge energy, so that the lithium-ion battery is stored longer. This is why the design is to charge the activation of the activation. If the iron lithium protector is activated due to limit flow, it is more troublesome after activation or completely disconnecting the load, but can also short the B- (battery negative) and P- (discharge negative) When you touch it, the protection will be released, remember to remember not to bring big loads shortly (for example, turn it out), otherwise it will take a lot of sparks, this root original is to protect the post-discharge MOS.

The large pressure is different, short-touch, pull the disc MOS DS level straight to 0V, this is released. Several ways to activate lithium-ion batteries can be discharged first: Make use of discharge or resistance discharge. Use discharge should be placed to the extent to which the boot is stopped; the resistance is discharged can take the small-time discharge of the corresponding voltage, until the small electric bead is immediately destroyed.

The discharge current is in a big thing. Activation: 12V AC power, in series, a rectifier diode forms a pulsating DC solution, then uses discharge or resistance and discharge, and finally charging the original manner. The principle is that pulsating DC can penetrate the capacitance of the passivation layer in the battery.

In the early days of the test, if it is charged with pulsation, it is not only fast, and the lithium ion battery life will be extended.
