CHARGE LEVEL DISPLAY WITH RANGE EXTENDER BATTERY
When the RE is attached to the bicycle, the charge level is displayed on the TCU, the TCD and the Mission Control
App. The displays adapt to show the state of charge for both internal and RE batteries.
With both the internal battery and the RE fully charged, the TCD will show the two charge levels separately (Fig. 11.5
A), but also combine the two charge level amounts (Fig. 11.5 B) to show a separate full charge level of 150 %. Logic
is that the RE holds half the capacity of the internal battery.

With both the internal battery and the RE fully charged, the TCU shows the charge level as overlaying light bars, the
internal battery charge level is displayed with 10 blue light bars and the RE charge level is displayed with 5 green
light bars (Fig. 11.5 A) (50% of the capacity of the internal battery).
The RE green light bars will overlay on the first 5 blue light bars of the internal battery light bars (Fig. 11.5 B) and will
hide some or all the blue bars depending on their state of charge. When the charge levels of both blue and green
bars are equal the green bars will show on top, as the charge levels drop, the color for the device with the lowest
charge level will show on top.
