For instance, when the EV accelerates with only considered energy consumption, but also the impact of the magnitude and number of accelerations in the multiple acceleration curves on the power battery capacity attenuation characteristics.
The voltage fluctuation of the power battery pack during the EV acceleration process is also very small, which can be regarded as a constant. Therefore, the capacity attenuation of the power battery in an acceleration condition can be obtained by substituting the cor-responding parameters:
Based on equal life loss, assuming that the battery capacity loss rate under 1C discharge rate is Qloss1 , and the battery capacity loss rate at nC discharge rate is Qlossn , the battery capacity loss under nC discharge condition can be deduced from Qloss1 = Qlossn as follows: where B1 = 27790 , Bn=36042 − 9419n+1215n2 − 48n3。 Figure 1.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
In the study of the impact of \ (T\), \ (n\), and \ (DOD\) on battery capacity, the battery capacity loss rate was used to predict the battery life, and according to the experimental results in reference 33, the battery capacity loss model of lithium-ion power batteries can be expressed as:
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
