Electric vehicles (EVs) are equipped with a sophisticated array of sensors that continually monitor and collect various parameters, forming the backbone of their data-rich nature. These sensors, strategically placed throughout the vehicle, provide critical information for vehicle performance optimization and user safety. One of the key sensor categories in EVs is temperature sensors, specifically designed to monitor the battery's thermal conditions. These sensors ensure that the battery operates within the optimal temperature range [5]. Maintaining the right temperature is crucial because extreme cold or heat can affect the efficiency, performance, and overall lifespan of the battery. By collecting and analyzing temperature data, EVs can make real-time adjustments, such as activating battery heating or cooling systems, to keep the battery within the ideal operating range.

Motor performance sensors are another essential component of EVs. These sensors continuously monitor the electric motor's performance, including parameters like motor speed, torque, and power output. This data helps in optimizing motor efficiency and ensures that the motor operates within safe limits. If an anomaly is detected, such as excessive heat or unusual vibrations, the sensor data can trigger protective measures, such as reducing motor power to prevent damage. Regenerative braking sensors are integral to maximizing the energy efficiency of electric vehicles. They monitor the braking process and collect data on factors such as deceleration rate and wheel speed. This information allows the vehicle to engage regenerative braking precisely when needed, converting kinetic energy back into electrical energy to recharge the battery. It not only improves energy efficiency but also extends the vehicle's range.

Additionally, exterior sensors, including LiDAR (Light Detection and Ranging) and cameras, are becoming increasingly prevalent in EVs, particularly those equipped with advanced driver-assistance systems (ADAS) and autonomous driving capabilities. These sensors provide critical data for features like adaptive cruise control, lane- keeping assistance, and autonomous parking [22]. LiDAR, for example, uses lasers to measure distances to objects and create detailed 3D maps of the vehicle's surroundings, enhancing situational awareness and safety.
