Hi all,

I'm a new user and have starting to develop/configure on the OVMS for Think City.

Currently I've made success with both SMS and App interrogation and it works well!

The result and some screenshots can be viewed at the Norwegian EV-forum in this post:

Due to some problems with the definition of global variables (changing more files than vehicle_thinkcity.c), I've been doing my development locally, not uploaded anything to GitHub.

The main problem is that the variable car_tbattery is defined as signed char.

Most Think City EV's have a "Zebra-battery" which operating temperature is about 270 degrees celcius (oC).

E.g. sending temperature 264 oC requires 9 bits -> 1 0000 10000

I think the signed char offers only 8 bits (bit 7 is set for negative numbers), and turns my value into

0000 1000 -> 8 oC ...

I understand that the OVMS-server (and the App) knows that car_tbattery is signed char, so to get around this I will ask if it's possible to redefine car_tbattery as signed int ?

As a second priority request, I would also ask if it's possible to add pack_voltage and pack_current to the global variables
ovms.c
unsigned int car_pack_voltage = 0; // Zebra battery pack voltage
signed int car_pack_current = 0; // Zebra battery pack temp

ovms.h

extern unsigned int car_pack_voltage; // Zebra battery pack voltage
extern signed int car_pack_current; // Zebra battery pack temp

I'm not sure how things are done here, so have me excused if I ask a little too much.

Best regards

Håkon
