Wherein, the relation between the service time of accumulator and residual capacity can be curve, a such as aging curve, also can be a series of data.The initial capacity of accumulator obtains in the pre-test of this accumulator use.
Such as, if the relation between the service time of accumulator and residual capacity comprises: accumulator is in use after 1 year, the residual capacity of this accumulator is the A% of its initial capacity, so, according to the relation between service time of accumulator and residual capacity, after accumulator uses 1 year, the current actual capacity of accumulator is A%*C0, and wherein C0 is the initial capacity of this accumulator.The initial capacity of accumulator is in the test before the use of this accumulator, the capacity of actual measurement.
S102, according to the actual capacity of described accumulator, described accumulator when the electricity of having released in previous charge and discharge process and the electricity be filled with, determine the current dump energy of described accumulator.
In S102, when determining the current dump energy of described accumulator, adopt the actual capacity of described accumulator as the dump energy of this accumulator at the end of a front charge and discharge process, actual is assume that this accumulator is filled with electricity at the end of a front charge and discharge process.
According to the current actual capacity of accumulator, described accumulator when the electricity of having released in previous charge and discharge process and the electricity be filled with, determine the dump energy of described accumulator, namely the current actual capacity A%*C0 of accumulator is deducted this accumulator and working as the electricity C released in previous charge and discharge process
-, add this accumulator and working as the electricity C be filled with in previous charge and discharge process
+, as the current dump energy C of this accumulator
r, i.e. C
r=A%*C0-C
-+ C
