In existing patent, also once there is the associated description to life condition formulating method, such as practical New Name is pre-
Estimate the method (patent No. 200610066313) of life of cell in digital camera, the patent is selected in the design phase of digital camera
With some components of digital camera, and enumerate the consumption power of the component；Calculated according to the consumption power of the component
When some different operation modes are performed, the consumption power under its individual operations pattern adds up to the digital camera；According to a mark
The circulation process of the execution digital camera test operation of quasi- testing process institute specification often carries out the flow institute of a circulation to calculate
The total power consumption for needing；And by the energy content of battery of a battery divided by the total power consumption, in the hope of the battery life estimated.
And for example a kind of entitled service life of battery of pure electric vehicle of patent of invention is calculated and warning device and its control method (patent
Number 200910144364), the patent predicts the original of battery performance by the life-span for predicting the method for battery performance to estimate battery
Reason is by cumulative battery depth charge and discharge cycles number of times, when battery depth charge and discharge cycles number of times reaches certain threshold value
Wait, automobile should remind driver to change vehicular high-power battery.
Compared with existing patent, a kind of life condition formulating method described in this patent is filled only by using battery
Discharge power just makes the life condition of battery.And above-mentioned two patent, respectively by calculating the consumption power of all parts
Realize that battery life is estimated with circulating battery number of times, the concrete condition of life condition is not substantially related to.And this patent
By the simple life test operating mode that battery has accurately just been made using battery charging and discharging power.
