    New Energy Vehicle Motor cooling system Pressure Detection
    新能源汽車是目前全球汽車產業發展的一個大趨勢,其中電動汽車為一個主要分支。電動機作為
    電動汽車驅動可實現極低排放或零排放。電動汽車在驅動與回收能量的工作過程中,電動機定子
    鐵芯、定子繞組在運動過程中都會產生損耗,這些損耗以熱量的形式向外發散。所以系統需要有
    效的冷卻介質及冷卻方式來帶走熱量,保證電動機在一個穩定的冷熱循環平衡的通風系統中安全
    可靠運行。電動機冷卻系統設計的好壞將直接影響電動機的安全運行和使用壽命。

    At present, new energy vehicle is a major trend in the development of the global auto industry, in which
    electric vehicles is a major branch. Motor as an electric vehicle power resource can achieve very low or
    zero emissions. In the process of driving and recovering energy of electric vehicle, the motor stator core
    and stator winding will generate heat in the process of movement. Therefore, the system needs
    effective cooling medium and cooling method to take away the heat to ensure the safe and reliable
    operation of the motor in a stable cold. The design of motor cooling system will directly affect the safe
    operation and service life of motor.
    新能源汽車驅動電機冷卻系統一般與電力電子箱(PEB:Power electrical box)共用,PEB 和驅動
    電機的工作溫度不能超過 75℃,*合適的工作溫度應該低于 65℃。將溫度控制在 75℃以下可以
    更好的延長 PEB 和驅動電動機的使用壽命。
    The motor cooling system is generally shared with PEB Power electrical box. The operating temperature
    of PEB and driving motor cannot exceed 75 ℃, and optimum working temperature should be below
    65 ℃. Temperature control under than 75 ℃ can prolong the service life of PEB and drive motor.

    所以廠家為了確認冷卻系統的可靠性和密封性,針對冷卻系統耐壓與密封性做出廠測試是必要

    的。系統耐壓測試壓力范圍 0~1.5MpaG, 需求測試精度>=0.2%FS,校準溫度范圍-20~80℃。密封
    測試壓力為 0.15MpaG,測試精度>=0.2%FS, 溫度范圍-20~80℃。
    Therefore, the OEMs are necessary to verify cooling system reliability and sealing performance before
    final assembly. The pressure range of over pressure test is 0~1.5MpaG, precision > = 0.2%FS, calibration
    temperature range-20 ~ 80 ℃. Sealing test pressure range is 0~0.15MpaG, test precision > = 0. 2%FS,
    temperature range-20 ~ 80 ℃.
