    HIGHLIGHTS

    供電池設計人員和使用者評估電池,以便運用於其設計中:

    • 單通道自放電量測系統
    • 在自放電電流高達 10 mA 時,電流量測準確度為 0.025%
    • 在電池電壓高達 4.5V 時,電池電壓量測準確度為 0.0016%
    • ± 10 μVpk 電源電壓穩定度(典型值)
    • 系統只需幾分鐘或幾小時便可準確量測自放電電流
    • 用於控制儀器、繪製結果、記錄和儲存資料的軟體

    是德科技的自放電量測系統可大幅縮短量測電池自放電電流所需的時間。對於圓柱形的 18650 或 21700 等小型電池,可在短至 30 分鐘至 2 小時內快速量測穩定的自放電電流,實際花費時間視電池特性而定;對於大容量的軟包裝電池(例如 10-60 Ah),整個過程可縮短至 1-4 小時。

    過去工程師需花費數週或數月的時間來等待電池開路電壓出現明顯變化,以便確定電池品質。相較之下,現在的量測系統可提供重大的改進。可顯著縮短測試週期,更快讓產品在市場中曝光。

    自放電量測系統使用恒電位量測法來快速量測自放電電流,並提供準確進行直流量測所需的功能特性:

    • 電池的最小干擾
      • 對電池施加的電壓可快速與實際電池電壓匹配(± 5 μV)。如此可有效減少新的充電或放電需求,進而將新的 RC 趨穩時間降到最低。
      • 對電池施加的電壓非常穩定(± 10 μVpk),可大幅降低自放電電流量測的持續電荷再分配電流雜訊。
    • 量測低位準自放電電流的準確度可達 ±(0.025% + 100nA)

    自放電量測系統也可以量測電池溫度。這方便您觀察電池電壓和自放電電流隨溫度的變化。由於電池擁有複雜的溫度係數,監測電池溫度有利於控制或消除溫度變化所造成的電池電壓變化。控制電壓變化可消除自放電電流量測的重要誤差源。您可以使用 BT2191A 標配的 T 型熱耦,或使用自己的感測器和接線。支援的感測器包括 T、J、K、E、N、R 型熱耦;5kΩ 熱敏電阻;Pt100 和 Pt1000 電阻溫度感測器。
