Property determine the ideal temperature rise rate corresponding temperature rising-time period, e.g., ideal temperature rise rate is 1 DEG C of s-1, it is determined that temperature rising-time cycle T
For 1s, in a temperature rising-time cycle T, in order to guarantee to detect 2 temperatures above data, when detection cycle Te is less than temperature rise
Between cycle T, detection cycle Te can be set to 0.9s, 0.8s or 0.5s here, in this way, realizing for battery to be charged
The detection of temperature, it is ensured that charging security.Optionally, the detection cycle Te be the temperature rising-time cycle T ten/
One.I.e. when temperature rising-time cycle T is 1s, detection cycle Te is 0.1s, it is ensured that charging unit can be in a temperature rising-time
