In subsequent time, the temperature value of battery drops to 0 DEG C from 25 DEG C.When 0 DEG C, full power consumption value c of battery0℃= 800mah, total discharge electricity amount value c of batteryout=200mah, then the residual electric quantity of battery is c0℃- cout=600mah, then When 25 DEG C, each corresponding charge value of electricity percentage ratio is 600/80=7.5mah.
Battery discharges when 0 DEG C 200mah, then now the dump energy percent value of battery is
soc _ left = 80 % - 200 ( 800 - 200 ) / 80 % × 100 % = 53.3 % . Show battery on mobile terminals Current residual electricity value be 53.3%.
In subsequent time, the temperature value of battery rises to 35 DEG C from 0 DEG C, the full power consumption value of battery when being calculated 35 DEG C c35℃=1100mah, total discharge electricity amount value c of batteryoutFor the discharge electricity amount value at 0 DEG C for the battery and the discharge electricity amount value at 25 DEG C Sum, i.e. cout=200+200=400mah.The residual electric quantity of battery is c35℃- cout=700mah, then 35 DEG C when each electricity The amount corresponding charge value of percentage ratio is 1100/53.3=13.1mah.
Battery discharges when 35 DEG C 200mah, then now the dump energy percent value of battery is
soc _ left = 53.3 % - 200 ( 1100 - 400 ) / 53.3 % × 100 % = 38.1 % . Show on mobile terminals The current residual electricity value of battery is 38.1%.
