[Ovmsdev] OVMS v3

[Michael Balzer]

Twizy users don't need locking / pre-heating etc., the controller 
parameter tuning is the currently most important Twizy OVMS feature (not 
available on other cars up to now).

Twizy user feedback:

The current OVMS is far too complex for normal people.

GSM is good as an option, but bad as a requirement. Needing to buy and 
insert a SIM card is already too much for many. GSM reliability and 
availability also is an issue for serious telemetry. The most simple 
logging setup should work with just an SD / USB memory stick, readable 
on any PC.

An OVMS v3 core version should be able to work with just a local Wifi / 
Bluetooth / USB connection. That could mean the GSM/GPS module becomes 
an extension module.

An optional separate display console could make it possible to use the 
OVMS even without a smartphone / laptop.

Software updates need to be possible without unmounting the OVMS, the 
PICkit flash procedure is way too much for ordinary users.

Average power consumption needs to be lower than now by a factor of ~10, 
it's bad needing to remember unplugging the OVMS if you leave for a week.

OVMS v3 also needs an ECE approval so it can be sold legally in Europe. 
Price may be higher than now then, by about 50-100%.

Linux would be great and would open the path to a broad user community, 
but I doubt that can be combined with the low power usage and pricing 
requirements... although, the Samsung NX300 shows it's already been done 
-- I have no idea about their hardware base though.

Regards,
Michael
