1. A system comprising:
at least one processor; and
at least one memory storing computer-executable instructions, that when executed by the at least one processor, cause the at least one processor to:
receive, from a first vehicle, a first value for a first data type, the first data type associated with a battery of the first vehicle;
determine, for the first data type, a first minimum value, a first maximum value, and a first offset indicator, wherein the first offset indicator provides an indication of a significance of the first value relative to the first minimum value and first maximum value for the first data type;
determine a first weight for the first data type;
determine, based on the first weight, a first weighted value for the first value; and
determine, using the first weighted value, a vehicle battery health score for the battery of the first vehicle.
