Since user is during using some electrical equipment 100 (for example, electric vehicles), often according to electrical equipment
When the battery dump energy of 100 prompts continues to use, the actual up time can significantly lower than the battery dump energy of prompt
It is out of power using time or even battery moment and cause using termination.Alternatively, battery is practical, there are also remaining capacities, but electricity consumption is set
Standby 100 prompt, at this time since remaining capacity fails to release, causes electrical equipment to shorten using the time without electricity, since user sees
The remaining capacity observed is not inconsistent with real experiences, to cause user's real experiences very poor.
Through present inventor the study found that the basic reason of the above problem is battery during the charging process or continuously
In use process, the state-of-charge (State of Charg, SOC) of battery is not corrected in time, so that state-of-charge
Error accumulation is increasing.For example, for electric vehicle, when measuring residual running mileage, if state-of-charge estimation misses
Difference is excessive, is likely to result in following risk: shortening because many electricity fail single mileage travelled caused by releasing, or because of battery reality
Border is out of power and stops on the way in traveling.
In view of the above-mentioned problems, in order to correct the error accumulation of the state-of-charge of battery, present inventor is taken in electricity consumption
It is modified by open-circuit voltage (OCV) when equipment 100 is stood, but is found for many electrical equipments 100, usually

More specifically, since battery has the influence of polarizing voltage during the charging process, and polarizing voltage is due to electricity
The potential difference that pole process is irreversible and makes electrode electromotive force deviate equilibrium electrod potential and generates, it may also be said to which polarizing voltage is real
The difference of border electrode potential and equilibrium electrod potential, and polarizing voltage in the charging process of battery the result is that anode corrigendum,
Cathode is more negative, and so as to cause the voltage curve of battery, the phase differs larger before charging with theoretical voltage curve, and polarizing voltage needs
A period of time it could be saturated or approach saturation, it is therefore desirable to select first charging voltage after a period of time.For example,
First charging voltage obtain at the time of can be after the battery starts to charge at the time of being filled with 20% electricity, at this time
In general polarizing voltage is already close to saturation.Certainly, first state-of-charge can also be not limited only to aforesaid way, ability

State is modified.
In the present embodiment, after getting the described first theoretical state-of-charge and the second theoretical state-of-charge, it is based on institute
The first theoretical state-of-charge and the second theoretical state-of-charge are stated respectively to the first state-of-charge of the battery and the second charged shape
State is modified, so as to complete the state-of-charge amendment in the charging process of the battery.
Based on above-mentioned design, the present embodiment can be subtracted by being modified during the charging process to the state-of-charge of battery
