Lead-acid charger K8012

Dear,
Intended to use K8012 to command alternator(on my sailboot).
Alternator: 12…18 volt/ max 35 Amp
Want to improve your intelligent batt.charger:
adding a batt.temp sensor to vary the end of current-charge periode.
The ref voltage should have a -22mV/°C tempcoeff.
Any suggestion?
Note: the T7 power stage will be modified to drive the alternator-rotorcoil.
Best regards
