As electric vehicles become more prevalent, ensuring the reliability of their electronic systems is paramount. One of the key challenges is protecting the CAN bus communication network from electrostatic discharge (ESD), which can reach up to 30kV in real-world conditions. This signal explores a comprehensive protection approach that addresses this vulnerability, covering system-level design considerations, component selection, and testing methodologies. The solution is critical for automotive engineers who must ensure that vehicles can withstand harsh electromagnetic environments without communication failures. With the rapid growth of the EV market, such reliability engineering practices are becoming increasingly important for both safety and customer satisfaction. This topic is particularly relevant for hardware engineers, embedded systems developers, and quality assurance teams in the automotive industry.
