Embodiment Construction
[0077] The present invention will be further described below in conjunction with accompanying drawing, implementation principle, simulation example and engineering application example, see Figure 1 to Figure 18 .
[0078] 1. Battery RC improvement model:
[0079] The RC model used in the present invention has a simple structure, can simulate the hysteresis effect of the battery, and has a resistance-capacitance parallel circuit that can well describe the nonlinear dynamic characteristics of the battery. The calculation amount is small, the calculation speed is improved, and it is better used in the engineering field. The structure of the traditional RC circuit model is as follows figure 1 . Resistance R o is the ohmic internal resistance of the battery, and the capacitance C p with resistor R p Parallel to simulate the polarization effect of the battery, R p Is the polarization internal resistance of the battery; the charge and discharge current is I, U o is the outpu...
