The PRF are obtained by dividing the simulated relaxation voltage curve by the value of the pulse current. These PRF provide a comprehensive description of the battery's voltage response characteristics to various currents. The continuous response characteristics of the battery system are the result of shifting and current-weighting the PRF.
The HPPC test involves applying a current pulse to the battery while recording the voltage response. The current pulse includes a discharge pulse followed by a relaxation period & then a charge pulse. This sequence is repeated at various SOC levels to comprehensively characterize the battery's performance over its entire operating range.
This equation defines the voltage response of a battery cell: V = V0 − I ×Ro − I ×(∑Ri(1 − exp(− tτi))), where: V0 is the cell open-circuit potential. Ro is the cell ohmic resistance. Ri and τi are the cell i -th RC pair resistance and time constant values. I is the current passing through the cell.
Generic methods for obtaining the parameters of this model involve analyzing the battery voltage behavior under step changes of load current. The fact that the model has two time constants places a challenge on parameter identification.
The high-precision voltage response equation of the battery under a pulse excitation has been provided in Eq. (7). According to the definition of the convolution sum, x k ∆ represents the value of the excitation at this moment, which corresponds to the value of the current.
The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
