/*
TODO:
- Find the following data points in the transmitted CAN data:
- SOC%
- SOH% (optional)
- Current
- Pack voltage
- Max discharge power
- Max charge power
- Temperature min
- Temperature max
- Cellvoltage min
- Cellvoltage max
- Alternatively all these values can be taken from OBD2 PID polling
- Figure out which messages need to be sent towards the battery to keep it satisfied and staying alive
- TODO: Test that the current amount of messages sent is enough to keep it alive
