\ud83d\udcca Cell Voltage & Battery Imbalance Analysis<\/h1>

Individual cell\/module voltage information can help identify abnormalities that may not be visible from total battery voltage alone.<\/p>

Technicians can use supported data to investigate:<\/p>

  • Weak cells or modules<\/p><\/li>

  • Abnormal voltage deviation<\/p><\/li>

  • Battery imbalance<\/p><\/li>

  • Charging irregularities<\/p><\/li>

  • Suspected battery degradation<\/p><\/li>

  • Battery warning messages<\/p><\/li>

  • Reduced EV range<\/p><\/li><\/ul>

    Battery voltage data should always be interpreted together with\u00a0SOC, SOH, temperature, current, DTC and manufacturer specifications<\/strong>.<\/p>

    \ud83c\udf21\ufe0f Battery Temperature Monitoring<\/h1>

    Battery temperature is critical to EV performance and safety.<\/p>

    The PRO3S+ EV can display supported temperature information to assist with diagnosis of:<\/p>

    • Uneven battery temperatures<\/p><\/li>

    • Cooling-system problems<\/p><\/li>

    • Temperature-sensor faults<\/p><\/li>

    • Thermal-management problems<\/p><\/li>

      • Installed control modules<\/p><\/li>

      • Modules containing DTCs<\/p><\/li>

      • Communication relationships<\/p><\/li>

      • Network faults<\/p><\/li>

      • Gateway structure<\/p><\/li>

      • Communication failures<\/p><\/li>

      • Overall vehicle network condition<\/p><\/li><\/ul>

        This is particularly useful on modern EVs containing many interconnected electronic control units.<\/p>

        \ud83d\udd04 Bi-Directional Control \/ Active Tests<\/h1>

        The PRO3S+ EV supports bi-directional control on compatible vehicles, allowing the scanner to command supported components directly.<\/p>
