Display Battery Info

[faraz-b]

Currently, the raw battery information that the driver would need is the Battery Voltage and the Battery Temperature

Phantom One Stats

State	Voltage	Temperature
Nominal	144V	35°C
Max	156V	60°C

*still need to confirm these stats

The current design idea is two rectangular bars at each top corner of the display as shown below:

• Design the progress bars and the different states (low/med/high voltage = red/yellow/green, low/med/high temperature = green/yellow/red)
• Encode the battery data into the color states

• for example, battery temperature between 40°C - 60°C would be in the red zone

• Create a test function that does a full sweep of the different states

FIRST CONTROLS SPRINT UPDATE:

1. Figured out the design of the battery temp and voltage display (shown in image above).
2. Chosen the number of bars to be 15 within each box (battery and temp). 5 bars will be red = very high temp, 5 bars will be yellow = warning temperature, 5 bars will be green = safe temperature. The number was chosen to be 15 because it is first of all divisible into 3 categories nicely. Second of all, the actual dashboard itself is quite small (155mm x 86mm), meaning that the size of the battery temp and voltage will only be about 5cm x 2 cm at most. Therefore, by drawing out a sample life-size model, it was determined that having 15 bars, each about 3mm, would be easiest for the driver to view, and enough bars to see smaller changes in temperature and voltage (for the safety of the driver).
3. Added buttons and animation that will represent the battery temperature/voltage increasing/decreasing.

4. Next steps:
   a. Talk to engineering (dynamics team) about what is the unsafe temperature, what should be warning temperatures, and what
   are acceptable/safe temperatures. Same for voltage.
   b. Make custom buttons that fit within the design box.
   c. Set the animation on a clock so it constantly updates and either disappears or appears based on the sample values of
   battery temperature/voltage.
   d. Maybe look into screen manager to help with animation of appearing and disappearing.
