When rate is the second charge power, the power input pin VBUS of charging interface 310 connects battery by power management chip 382
330.Power management chip 382 includes protection circuit, can be directly short by the power input pin VBUS ground connection of Type-C interface
Road stops charging, realizes the temperature decline of type-C interface.
When external recharging apparatus 200 and charging equipment 300 are fast charge mode, i.e., when target charge power fills for first
When electrical power, the power input pin VBUS connection external recharging apparatus 200 of charging interface 310, the power supply of charging interface 310 is defeated
Entering pin VBUS can also be directly connected to or connect battery 330 by first switching element 371.The electricity of external recharging apparatus 200
It can directly be filled to the battery 330 of charging equipment 300, can be realized powerful fast charge.Meanwhile external recharging apparatus 200 with to
Without passing through battery management chip 382 between the battery 330 of charging equipment 300, if when charging interface 310 such as Type-C interface
When having foreign matter or feed liquor body, it will appear short circuit between the pin of Type-C interface, due under straight mold filling formula, charging interface
310 pin is directly electrically connected with battery 330, does not have the progress of battery management chip 382 between charging interface 310 and battery 330
Protection, it is excessive and easy by Type-C interface and charging equipment that the generation short circuit of Type-C interface will lead to electric current in a short time
300 burn.If the temperature value of Type-C interface beyond safe temperature value range constantly, first by Type-C interface and battery 330 it
It is separated to exit fast charge, into normal charging mode.
