×(cte-cts)/(te-ts) in, obtain tnCorresponding full power consumption value ctn.
For example, temperature initial value t of temperature ranges=25 DEG C, tsFull power consumption value c of corresponding batteryts=1000mah,
The temperature stop value t of temperature rangee=0 DEG C, teFull power consumption value c of corresponding batteryte=800mah, current temperature value tn=2 DEG C
When, then ctn=800+ (2-0) × (1000-800)/(25-0)=816mah, or ctn=1000+ (2-25) × (800-100)/
(0-25)=816mah.
Step s203, obtains tnCorresponding discharge electricity amount value △ ctn.

cout.
In an embodiment of the present invention, when the temperature of battery is from a upper temperature value tn-1Become and turn to tnWhen, obtain and become in temperature
Moment, dump energy percent value soc_left of battery and the total discharge electricity amount c changingout.
coutFor battery temperature from a upper temperature value tn-1Become and turn to tnWhen, the electric discharge electricity of battery under temperature value before
The summation of value.For example, under original state, battery is in full power state, is t in temperature value0When start discharge, battery is in temperature
It is worth for t0When discharge electricity amount value be △ ct0=100mah, is t in temperature value1When discharge electricity amount value be △ ct1=200mah,
Current temperature value is t2, then cout=△ ct1+△ct0=300mah.
Step s205, calculates current temperature value tnDump energy percent value soc_now of lower battery.

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
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
The dump energy percentage of battery when the temperature of battery continues to change, can be recalculated according to above-mentioned steps
