Stream size carries out quick charge.Arranging threshold value is 5 DEG C/min, i.e. represent when in charging process per minute rise above 5 DEG C time, stop
Only being charged for battery, design temperature variation tendency threshold value is 4 DEG C/min, i.e. rises above 4 when per minute in charging process
DEG C time, then need charging current is adjusted, such as, adjust rate of charge, the charging current of original 5C multiplying power is adjusted
For the charging current of 2C multiplying power, to reach the effect of regulating cell temperature.
404, according to temperature changing trend, the charge data of battery is adjusted, and uses the charge data after adjustment
Battery is charged.
By detecting the temperature changing trend of battery, so may determine that battery whether it is possible that abnormal, if battery
Variations in temperature labile state occurs, such as, the rate of rise in temperature of battery is very fast, then can enter the charge data of battery
Row sum-equal matrix, such as, adjusts charging current, adjusts charging voltage etc., and use the charge data after adjustment to be charged battery.
405, the temperature changing trend of battery is again detected.
Battery in normal state, after being adjusted the charge data of battery, the temperature of corresponding battery has
Changed, the temperature changing trend of the battery after specifically can being adjusted by detection, such as, if reducing the charged electrical of battery
Stream, detects the temperature changing trend of battery again, and the temperature of battery begins to decline, then can be determined that the charging current before adjustment

Such as, in method of adjustment example one, when intensification per minute in charging process reaches 8 DEG C, then exceed the temperature of setting
Degree variation tendency threshold value (4 DEG C/min), needs to reduce the size of charging current, and after charging current reduces, the temperature of battery is opened
Begin to decline, then can be determined that the excessive battery temperature caused of the charging current before adjustment rises.
The most such as, in method of adjustment example two, when the temperature of battery reaches 50 DEG C in charging process, exceed filling of setting
Electro-temperature adjusts preset value (40 DEG C), needs to reduce the size of charging current, and after charging current reduces, the temperature of battery starts
Decline, then can be determined that the excessive battery temperature caused of the charging current before adjustment rises.
The most such as, in method of adjustment example three, rise above 5 DEG C when battery is per minute in charging process, extend and charged
Electric discharge duration in journey, the temperature of battery begins to decline, then can be determined that the electric discharge too short battery caused of duration before adjustment
Temperature rises.
The most such as, in method of adjustment example four, rise above 5 DEG C when battery is per minute in charging process, reduce charging times
Rate, the temperature of battery begins to decline, then can be determined that the excessive battery temperature caused of the charging current before adjustment rises.
If the temperature changing trend after 406 adjustment charge data is identical with the temperature changing trend before adjustment charge data,
Stop being charged for battery.
After charge data is adjusted, if the temperature changing trend after Tiao Zhenging and the variations in temperature before adjustment charge data
Trend is identical, and i.e. after adjusting charge data, the temperature of battery does not occur to change accordingly, adjusts with to charge data
Variations in temperature before adjustment is identical, then it is believed that battery is in abnormal condition, it may be possible to due to except charge data surprisingly
