1. A method in a telematics device coupled to a vehicle including a battery, the method comprising:
determining that a vehicle type of the vehicle is one of: an electric vehicle (an EV), an internal combustion engine vehicle (an ICEV), and an unknown type;
in response to determining that the vehicle type is an unknown type or is an EV:
comparing, by a comparator, a battery voltage of the battery, with a charging threshold;
in response to determining that the battery voltage is above the charging threshold:
when the vehicle type is an unknown type:
querying the vehicle for the vehicle type;
saving the vehicle type;
obtaining telematics data from the vehicle, and sending the telematics data to a remote server;
in response to determining that the vehicle type is an ICEV;
comparing, by the comparator, the battery voltage with a cranking threshold;
in response to determining that the battery voltage is below the cranking threshold:
capturing a plurality of cranking voltage values;
checking for at least one indicator that indicates that the vehicle is turned on; and
in response to determining that the vehicle is turned on, obtaining telematics data from the vehicle, and sending the telematics data to a remote server.
