Trip summary values are detailed by Time, Moving and EV.
Time is the total trip time.
Moving stats regards only the fraction of time while the car was not standing still.
EV stats are accounted only when the petrol engine is stopped.
No Fuel sums EV driving with the petrol engine running without fuel like coasting at high speed or driving down a slope.

Charge and discharge kW limits for the battery.
These values may change with battery level and temperature.
When the battery is nearly full, charge limit is reduced.
On low temperatures, charge and discharge limits are reduced to preserve battery life.

Statistics for each battery block.

  • Min: minimum observed value.
  • Max: maximum observed value.
  • % Time @ Min V: time percentage the given block was the lowest of the battery; high values may indicate a weak block.
  • Bias: difference from the highest block.
  • Local Delta: how much a block differs from its immediate neighbours.

    Maximum delta value between highest and lowest block is the most important parameter for battery health: high delta values suggests a weary battery.
    Delta values are significant only when repeated over a long time: the table counts consecutive samples where delta value is over the indicated threshold.
    Low counts are not an indication of a fault while high counts may be.

    Car operational state statistics during the trip.
    States are expressed as percentage over the entire trip time and longest time span the state persisted.

  • Pulse: accelerating with nearly all ICE power given to traction.
  • Approximate Glide: cruising with no electrical or mechanical traction (approximate evaluation).
  • Coasting: cruising with no accelerator or brake applied.
  • Heretical: cruising with MG1 electric motor providing traction.
  • Accelerator pressed: accerator pedal is pressed, even if not actually accelerating.
  • Accelerating: car speed is increasing.
  • Moving: car is not stopped.


    • Driver Evaluation
    Accelerator Nervousness 2.12
    Inefficient Ignitions 0/3

  • Accelerator Nervousness: Variability of the accelerator pedal usage. Higher values indicate a nervous driving style
  • Braking Efficiency: Ability to use regenerative braking
  • Inefficient Ignitions: Number of engine ignitions that lasted less than 5 seconds


    • Notes

    Point size on scatter charts is proportional to number of samples: a small, well defined dot represent a higher confidence value than a bigger, faint dot.
