The temperature of charging path is 33 DEG C, compares the temperature of the second charging path and the 4th charging path.
Step 206, the charging current of the higher charging path of temperature is reduced, and/or, improve the lower charging path of temperature
Charging current.
In the present embodiment, the higher charging path of temperature and the lower charging path of temperature are obtained by comparing, reduces temperature
The charging current of higher charging path is spent, and/or, improve the charging current of the lower charging path of temperature.Specifically, it obtains
After the higher charging path of temperature and the lower charging path of temperature, the charging current of the higher charging path of temperature is reduced, or
Person improves the charging current of the lower charging path of temperature, or is reducing the same of the charging current of the higher charging path of temperature
When, improve the charging current of the lower charging path of temperature.For example, the temperature of the second charging path is 36 DEG C, the 4th charging is logical
The temperature on road is 33 DEG C, and the temperature of the second charging path is higher, and the temperature of the 4th charging path is lower, then by the second charging path
Charging current 2A be reduced to 1.5A, while the charging current 2A of the 4th charging path is risen into 2.5A.
In conclusion the embodiment of the present invention, charging system includes four charging paths.When charging, according to determining charging
Attributions selection one or more charging path charges.The temperature for acquiring charging path is adjusted according to the temperature of charging path
The size of charging current, equipment hot-spot when avoiding charging.Through the embodiment of the present invention, a variety of chargings can be compatible with when charging
Device improves charging rate, has dispersed the region of charging fever.
