Today’s electric cars rely on various signalling methods plus electronic parts to keep systems running smoothly. A test setup described here combines three kinds of data links - SPI, CAN, and LIN - alongside flexible relay handling. Instead of slow wiring, SPI moves information quickly over small gaps to detectors and add-ons. Main computing modules - the VCU, BMS, and drive converter - talk through CAN, which holds up well under stress and responds fast. For simpler tasks like managing lights or windows, LIN cuts costs without needing heavy hardware. Each protocol fits a different role, balancing speed, reliability, and expense across the car's nervous system. Despite their compact size, flex relays manage both high- and low-power circuits without risk. Through hands-on exploration, the system reveals how EVs exchange data, link protocols, and execute control logic. This approach builds familiarity with actual electric vehicle operations over time.
