Electrical car battery voltage rankings are more and more transferring from 400 V to 800 V, whereas massive vitality storage techniques are progressing from 600 V-900 V to as excessive as 1,500 V. Check engineers assessing hardware-in-the-loop (HIL) necessities for battery administration techniques face a dilemma between the variety of simulated cell channels and the accuracy of the simulation.
When there are inadequate cell channels, techniques typically have to be scaled down utilizing particular take a look at firmware for the machine underneath take a look at (DUT). This methodology neglects the complexities of actual techniques that encompass a whole lot of cells, making it difficult to precisely mannequin multi-point faults or situations involving interactions between completely different failures. Conversely, using battery cell simulators with the mandatory variety of channels will be prohibitively costly and require substantial area.
Excessive-voltage lithium-ion battery packs for electrical autos and enormous vitality storage techniques sometimes function with a distributed battery administration system (BMS) structure that features Battery Management Models (BCU) and Battery Administration Models (BMU). For additional particulars on utilizing ISO-SPI simulation know-how to duplicate the interactions between BCU and BMU, think about downloading the associated whitepaper.
