電池管理系統是現今電動車發展的關鍵技術之一，其中電池之電流、電壓偵測技術在電池管理系統是安全相關項目。本論文提出適用於電池管理系統之高壓電流偵測器，並以晶片實現相當高精準度之解決方案。

由於電池模組皆由許多電池串聯、並聯組成，因此會需要面對高壓問題，本論文提出適用於電池管理系統中高壓電流偵測器，確保電晶體跨壓不會超過製程廠的電壓限制，並將偵測電阻整合在晶片上，以減少離散元件的使用。模擬結果電壓範圍為20 ~ 40 V、電流範圍為0.5 ~ 1 A，最大誤差為± 2.6 %內。

另外由於行政院環保署制定了電動二輪車電池交換系統共通電池審驗規範，訂定了電動二輪車交換系統中電池組的公稱電壓為48 V，根據此一規範提出一適用於現今法規公稱電壓之高壓電流偵測器，同樣能適用於電池管理系統中。量測結果在電壓範圍為36 ~ 55 V、電流範圍為0.44 ~ 2.2 A的情況下最大誤差在± 1.6 %以內。

Battery management system (BMS) is one of the key technologies of electric vehicles (EVs) nowadays. The current sensing technologies are critical factors of the safety of BMS. This thesis presents for high-voltage current sensor designs for BMS. The proposed sensors are realized on silcion to demonstrate high accuracy.

Since the battery modules are composed of many parallel modules with batteries in series. Therefore, it inevitably will face high-voltage and high-current problems. A high-voltage current sensor is demonstrated in this thesis using HV CMOS process for BMS. The voltage of MOSFET is kept under the HV CMOS process limitation. The sensing resistor is integrated on silicon as well to reduce the number of discrete elements on PCB. The current sensor is adeguate in the voltage range from 20 to 40 V and the current range from 0.5 to 1 A. The maximum error is within ± 2.6 % by all-PVT-corner simulation.

Environmental Protection Administration, Executive Yuan, formalized an official specification of battery modules of electric motorcycle battery exchange systems. The nominal voltage of the electric motorcycle battery exchange system is defined as 48 V. According to this regulation, a high-voltage current sensor is proposed for the BMS used in the exchange systems. The maximum error in the voltage range of 36 ~ 55 V and the current range of 0.44 ~ 2.2 A is less than ± 1.6 % by physical measurements.
