Conventional Static Power Distribution Techniques limit the vehicle’s range and energy efficiency due to their inability to adapt to dynamic driving conditions. This paper proposes an Intelligent Power Distribution Technique enabled by a Deep Neural Network-based battery management unit (BMU), implemented on an FPGA architecture. The MPSoC efficiently interfaces with multiple sensors, including Hall Effect sensors for speed and voltage measurement, a shunt-based current sensor, and a potentiometer for throttle position detection. Data collection was conducted in Chennai, India, where key parameters such as speed, throttle position, battery voltage, battery current, and GPS coordinates were recorded at 10-min intervals over 30 days. The performance evaluation of the FPGA implementation reveals optimized chip area utilization (97.25 mm<sup>2</sup>) and reduced power consumption (6.391 W) compared to conventional battery management systems. Additionally, an LSTM-based State of Charge (SoC) estimation model was developed, outperforming traditional Coulomb Counting and Kalman Filtering methods with an MAE of 0.0250 and RMSE of 0.0288. Dynamic power distribution techniques further optimized energy consumption across different driving cycles, leading to a notable improvement in EV mileage. Compared to static power allocation, the proposed intelligent power distribution technique achieved an increase of 7.8% (471.09 km) in urban driving, 12.21% (490.33 km) in highway conditions, and 10.8% (484.20 km) in downhill scenarios. Sensitivity analysis of speed and throttle position on battery voltage and current highlights crucial insights for efficient energy management. The proposed i-BMU enhances battery longevity, reduces power consumption, and improves overall EV efficiency, making it a promising solution for next-generation electric mobility.</p></div>","PeriodicalId":7827,"journal":{"name":"Analog Integrated Circuits and Signal Processing","volume":"123 3","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, biometric-based authentication is widely adopted as it reduces impersonation fraud and account takeover attacks. Biometric data are relevant to the user’s personal information and can potentially be exploited by the attacker to compromise the user’s additional data. Hence, the protection of the biometric data is also vital, along with the secure authentication of the protected data. This proposed work, a 2FA mechanism is implemented using the Spread Spectrum Watermarking method. Instead of storing fingerprint biometric data in the database, it is embedded in the physical token/security token as invisible watermarking with the user’s image. The user’s unique ID (UID) is stored in the database and embedded as an invisible watermark in the physical or security token, the second factor. This physical or security token, commonly known as a ‘smart card, ‘is a portable device that stores the user’s authentication information and can be used for secure access to systems and services. It becomes a smart card once authentication factors and other user information are embedded. The user’s fingerprint is compared to the embedded fingerprint on the smart card for identification to access protected data. To further validate the user’s identity, the embedded UID is decrypted and matched against the stored UID in the database. A detailed simulation analysis demonstrates the enhanced outcomes of the proposed watermarking-based 2FA model.
