First, we need to understand what a sensor is. A sensor is a device that detects physical or chemical quantities in the environment, such as temperature, pressure, light, sound, and magnetic fields, and converts this information into electrical signals for other devices to process or record. In a car, sensors are responsible for monitoring various vehicle parameters, such as vehicle speed, engine speed, battery status, and tire pressure, to ensure the car's safety and performance.
The number of sensors in new energy vehicles varies depending on the model and configuration, but is generally more than in traditional gasoline vehicles. This is because new energy vehicles require more sensors to monitor battery status, motor operation, charging process, and so on. Furthermore, to achieve advanced functions such as autonomous driving and intelligent navigation, even more sensors are needed, such as radar, lidar, and cameras.
Specifically, a new energy vehicle may include the following types of sensors:
Safety: The Key Role of Thermal Runaway Gas Sensors
In new energy vehicles, battery safety is paramount. Thermal runaway gas sensors detect gases and smoke generated in the early stages of battery thermal runaway, enabling timely detection of potential fire risks. When an anomaly is detected, the sensor quickly triggers the vehicle's audible and visual alarm system, alerting occupants and allowing them to react immediately, thus protecting lives and property.
Comfort: Sensors that monitor air quality in real time
The vehicle's air quality sensors and laser dust sensors are responsible for monitoring the air quality inside the vehicle. They can detect various air quality indicators such as carbon dioxide and PM2.5 dust in real time to ensure fresh air inside the vehicle. By linking with relevant in-vehicle control systems, these sensors can automatically adjust the vehicle's ventilation and purification equipment to provide passengers with a comfortable riding environment and help prevent driver fatigue caused by polluted air.
Intelligentization: Innovative Applications of Life Residue Detection Sensors and Flexible Micro/Nano Sensors
Victim detection sensors are a major highlight of the intelligence of new energy vehicles. Using methods such as infrared detection and carbon dioxide concentration detection, these sensors can accurately determine whether any living beings have been left inside the vehicle, especially vulnerable groups such as infants and pets who are easily forgotten. Flexible micro-nano sensors show even more diverse application prospects, such as heart rate and respiration monitoring, and heated seat fabrics, providing passengers with more personalized and comfortable services. Furthermore, high-precision MEMS inertial measurement units also play a crucial role in autonomous driving technology, providing vehicles with accurate positioning and navigation.
Sensor requirements in the manufacturing process
Besides the high demand for sensors inherent in new energy vehicles themselves, their manufacturing process is equally reliant on sensors and related equipment. The manufacturing process of new energy vehicles involves numerous hazardous factors, such as VOCs generated in the painting workshop, the risk of LNG leaks from the drying furnace, and toxic and harmful gases in the final assembly workshop. These sensors can monitor various parameters in the production environment in real time, ensuring the safety and efficiency of the production process.

In summary, the number of sensors in a single new energy vehicle may range from dozens to hundreds. These sensors work together to provide the vehicle with powerful sensing and control capabilities, resulting in significant improvements in performance, safety, and energy efficiency.
With technological advancements, the number and types of sensors in future new energy vehicles will continue to increase. For example, more advanced autonomous driving technologies require more sensors to perceive the surrounding environment and achieve higher levels of autonomous driving. Furthermore, with the development of technologies such as the Internet of Things and 5G, new energy vehicles will also achieve closer connections and interactions with their surroundings, other vehicles, and infrastructure, which also requires more sensors to support them.
In summary, sensors are an indispensable and crucial component of new energy vehicles. Like the car's "sensory organs," they constantly monitor the vehicle's status and environmental changes, providing accurate and timely information to ensure safe and efficient operation. With the continuous development of new energy vehicle technology, sensors will play an even more important role in the future.
