The voltage of electric vehicle batteries is increasing from 400V to 800V, and the voltage of large-scale energy storage system batteries is rising from 600V-900V to 1500V. Engineers face a dilemma when proposing hardware-in-the-loop (HIL) requirements for high voltage battery BMS: the number of battery cell channels versus the simulation effectiveness. When the number of … Read more
In electronic engineering and embedded development, terms like CPU, MCU, MPU, SoC, DSP, ECU, GPU, and FPGA are often mentioned.
