Customer ServiceA novel network structure for power battery anomaly detection based on an improved TimesNet is proposed, achieving an improvement of 1%–19% in the F1 value and 1%–3% in the ACC compared to the other models. Health monitoring and abnormality detection of power batteries for new energy vehicles has been one of the hot topics in recent years.
Customer ServiceTo determine accurately the total charge as the integral of the current value, absolute accuracy in mA is required in the current sensor. Furthermore, this measurement must be performed in the automotive temperature range of − 40 to 85 °C. (a) Battery current sensor usage in the EV.
The maximum current exceeds 126 A, while the average is 14 A. At present, commercially available current sensors, which can measure up to several hundred amperes, have an accuracy of 1 A. If the average current is 10 A, this accuracy requires 10% (= 1 A/10 A) margin in estimating the battery state of charge.
Current from the battery module with stacked cells passes through the busbar in the junction box and is measured by the current sensor.
The design uses the differential detection of two sensors to eliminate in-vehicle common-mode environmental noise, and a mixed analog–digital control to trace the magnetic resonance microwave frequencies of the quantum sensor without deviation over a wide dynamic range. The prototype battery monitor was fabricated and tested.
The prototype battery monitor was fabricated and tested. The battery module current was measured up to 130 A covering WLTC driving pattern, and the accuracy of the current sensor to estimate battery state of charge was analyzed to be 10 mA, which will lead to 0.2% CO 2 reduction emitted in the 2030 WW transportation field.
Therefore, the state of charge has to be estimated with an ambiguity of approximately 10%, which makes the battery usage inefficient. This study resolves this limitation by developing a diamond quantum sensor with an inherently wide dynamic range and high sensitivity for measuring the battery current.
