The CC,CV and restart threshold would vary based on the battery temperature
So I would suggest to have temperature zone table as part  of battery info
along with other attributes.

int iterm; //charge termination current (used to stop charging)
int temp_zone_count; // number of temperature zone tables present
struct batt_temp_mon_table temp_mon_tbl[MAX_TEMP_MON_TABLE]; //temperature zone table array

struct  batt_temp_mon_table {
	 short int temp_max;
	 short int cc;
	 short int cv;
	 short int vbat_vchk_drop_uv;
	 short int temp_min;
};
