新能源汽車對傳感器提出的新要求和挑戰更高的精度和可靠性： 三電系統（尤其是高壓電池）對電壓、電流、溫度的測量精度要求極高，任何偏差都可能導致性能下降或**隱患。傳感器必須在車輛整個生命周期內保持穩定可靠。更強的抗電磁干擾能力： 大功率電機驅動和高壓系統產生強電磁場，傳感器需要優異的EMC性能。更寬的工作溫度范圍： 電池和電機在工作時會產生熱量，傳感器需要耐受高溫；同時車輛也可能在極寒地區使用。更長的使用壽命和耐久性： 新能源汽車設計壽命長，傳感器需要與之匹配。更高的集成度與小型化： 車輛空間有限，尤其是電池包內部，需要高度集成和小型化的傳感器。成本壓力： 新能源汽車成本敏感，需要在性能和成本之間找到平衡，特別是對于ADAS中使用的高成本傳感器（如激光雷達）。功能**要求： 涉及車輛關鍵控制（如BMS、制動、轉向）的傳感器需要滿足ISO 26262等功能**標準的要求。數據處理與融合： ADAS/AD產生海量異構傳感器數據，需要強大的計算平臺進行實時處理、融合和決策。
