FAQ

    High-voltage upon arrival

    The ambient temperature is relatively high. As the temperature rises, the open-circuit voltage of LFP slightly increases; therefore, higher warehouse or transportation temperatures will make it appear even higher.

  • Large voltage difference between individual strings in the module

    Reason 1: Cell performance differences
    Reason 2:     Module assembly and connection process issues
    Reason 3: Thermal non-uniformity
    Reason 4:     The pressure differential has increased due to the customer’s operating conditions
    Reason 5:     The data acquisition line is inaccurate

  • Client testing process issues

    Reason 1: The data acquisition line is inaccurate

    Reason 2: A certain string of battery cells has completely failed or is short-circuited.

    Reason 3: Severe over-discharge

    Reason 4: Internal micro-short circuit leakage

    Reason 5: BMS/sampling issue (appears to be low voltage)

  • Low-capacity module aging

    Reason 1: Low ambient temperuture
    Reason 2:     The charging and discharging procedures recommended by different companies show discrepancies
    Reason 3: Large voltage difference among sorted and matched cells
    Reason 4:     Abnormal performance of individual battery cells
    Reason 5: Module process technology issues


  • High internal resistance of the battery cell

    Reason 1: Different test frequencies. It’s common for factories to use AC internal resistance at 1 kHz, while customers typically measure DC internal resistance (DCR) or low-frequency resistance—values measured under different voltages can differ by 10% to 30%. As a result, customers may perceive the “internal resistance as high.

    Reason 2: Inconsistent test voltage/SOC. The internal resistance of LFP varies depending on the SOC; refer to the reference table provided by the manufacturer for comparison.

    Reason 3: Low temperature. When the ambient temperature is below 20℃, the internal resistance of LFP batteries will increase significantly. It's normal for the internal resistance to be high in winter or in cold warehouses.

  • Excessive self-discharge

    Reason 1: Overcharging and overdischarging. This damages the structure, triggers side reactions, and significantly increases self-discharge.

    Reason 2: High-temperature storage/high-temperature transportation. Temperatures exceeding 45℃ will significantly accelerate side reactions, leading to faster pressure drop.

    Reason 3: The battery was tested immediately after high-current fast charging without allowing it to rest. The voltage appeared artificially high but quickly dropped once the battery was allowed to sit, giving the impression of significant self-discharge.
