Issue Description
==================

Based on the power supply rating, we need to calculate the lifetime of the car battery if
the system is running whilst the car is sat for a prolonged period.

As part of testing, have removed the power supply from the powered hub.

Currently, running from the 1A power supply powering the Pi is

- WLAN adapter
- GPS dongle

Haven't yet tried a reboot to ensure that the GPS is able to get a fix with the available
power (though it should be able to) but the maximum possible power consumption at the
moment is 1A, meaning a 70A/h battery will power the system for 70 hours.

However, due to authentication issues with the access point (which is definitely the AP
and not the Pi at fault) the Wifi isn't currently connected. Need to test that it can
establish and maintain a connection.

Will need to run a similar test once VEHPI-13 is implemented

Bulk Close.

Realistically, project isn't going to see any further development so closing as Won't Fix
