Cell Balancing

The cell balancing (AKA Equalize) feature in this release has been designed with a focus on conserving energy. The key points of this feature include:

  1. Logic: For simplicity and to minimize development efforts, the cell balancing logic has been hardcoded in this release.
  2. Trigger Conditions: To mitigate loss of energy due to inefficiencies, cell balancing will only be activated when:
    • The battery voltage is above 6.3V.
    • The cell voltage delta exceeds 100mV.
    • The battery is in a charging state.
  3. Cell balancing: If the specified conditions are met, cell balancing will initiate and continue for 10 minutes. After this duration, the system will sample the voltage delta. If the delta is below 100mV, the cell balancing process will be terminated.
  4. Safety: Cell balancing will not occur if the cell voltage delta is above 2V, or if any individual cell voltage falls below 1V. In such cases, the system relies on charging to balance the batteries to an acceptable state so then cell balancing can complete the job.
