Broken Controller Boards and Programmers
- Could not find a working controller board and a working programmer
- Bring up backup CBs and flash programmers before the race
- Identify the causes of broken CBs and programmers
BPS
- The carrier and the AFEs should be fully tested before the race
- We should have at least one backup carrier and one or two backup AFEs for quick replacement
- Backup ICs are necessary
Flashing the Controller Boards
- Experienced difficulty in flashing controller boards in hard-to-reach places (e.g. pedal board)
- Investigate firmware update OTA via CAN
Motor Controller Interface
- Unable to consistently read motor speed and temperature data on the motor CAN bus
- Investigate MCU with two CAN controllers
- Improve SPI-CAN driver
Waterproofing
- The thunderstorm was a concern in the beginning of the race
- The motor controller interface was damaged due to water
Telemetry
- The LTE dongle provided a very reliable internet connection for telemetry purpose
- Considered using long-range Wi-Fi for telemetry but the equipments are very expensive
Solar
- Solar sense was not functional during the race due to firmware issues
- Investigate behaviour of the MPPTs (i.e. pack voltage vs. charging current)
- Did not have any documentation regarding the solar enclosure
