Battery management systems (BMS) are becoming essential for all types of electric vehicles using battery packs. Various factors, such as battery temperature and balance, directly affect the life, safety, and efficiency of batteries used in vehicles. For security and robustness, these factors should be monitored and adjusted instantly. Today, battery management systems are constantly being developed using different production methods and algorithms. In the studies, calculations are made by measuring parameters such as temperature, current, current balance, load status, and health status of the battery cells, and the control of the battery group is provided with these calculations. Instant and continuous measurement and processing of all these data and the creation of a control algorithm according to the calculation result are possible with the use of powerful processors. FPGA is a processor that can provide the speed and functionality required for BMS. In the battery management system, the FPGA is responsible for receiving and processing all signals from the battery cells and producing results. It instantly processes the data from temperature, current, and voltage sensors and applies the control stage required for balancing. In addition, the charge and discharge capacity of the battery is calculated by instantly measuring the state of charge (SOC). SOC is of great importance in the battery management system to ensure the safety of the battery pack. Therefore, the SOC needs to be estimated accurately and in real-time. Thanks to its parallel processing capability, the FPGA can simultaneously read data from the sensors and perform related calculations. In this study, a versatile system design with real-time, high computational speed for BMS was carried out on FPGA. The voltage and current of an experimental battery based on the embedded system were monitored in real time in a simulation environment. Experimental results show that the instantaneous SOC estimation is successful, and the system returns instant results to the incoming sensor data. The use of FPGA as a management unit will provide significant advantages in BMS with its high operating speed, real-time monitoring, low power consumption, and re-programmability.

“…In contrast, current-sensing schemes, such as open-loop MR or HE, can be highly susceptible to such fluctuations. To avoid this, temperature compensation can be implemented in the sensor to ensure accuracy [ 67 , 68 ]. The unit to quantify the thermal drift of a current sensor is ppm/K, and any value below 100 ppm/K is considered acceptable [ 9 ].…”

Precise current sensing is essential for several power electronics’ protection, control, and reliability mechanisms. Even so, WBG power converters will likely struggle to develop a single current-sensing scheme to measure various types of currents due to the limited space and size of these devices, the required high sensing speed, and the high electromagnetic interference (EMI) emissions they cause. Analysis of existing current sensors was conducted in such terms with the objective of understanding the challenges associated with their integration into WBG power converters. Since each of these requirements has different design tradeoffs, it is challenging to consider one specific method of current sensing to be perfect for all situations; thus, the possibility of developing novel methods to improve the performance of these single-scheme current sensors is further explored.

For the temperature drift problem of a shunt-type current sensor, this paper adopts a temperature compensation model based on the fusion of temperature segmentation linear and clustering division, which focuses on the consideration of the current sensor system as a whole, as well as versatility and complexity, etc., to ensure the measurement accuracy of a single sensor, while improving the speed of multi-sensor temperature compensation. Experimental results show that the current sensor after the model compensation, in the 15 A or more experiments measured in the current range of the accuracy is maintained within ±0.5%, compared with the sensor before the compensation of the measurement accuracy increased by 3%, but also reached the domestic and foreign current sensor products in the corresponding range of the compensation of the accuracy. The model effectively improves the temperature stability of the sensor and the system detection accuracy and provides practical application value for the temperature compensation of shunt-type current sensors in mass production.
