Abstract
The present disclosure relates to systems and methods for analyzing health of vehicle batteries and vehicle electrical systems. Vehicle batteries, as well as other components of a vehicle electrical system, tend to degrade over time, and eventually fail. The described systems and methods generate an electrical system metric based on electrical data from a plurality of vehicles. Electrical system performance of individual vehicles is compared to the generated electrical system metric, to determine electrical system performance of vehicles relative to other similar vehicles.
Claims18
A method comprising:
- determining, by at least one processor for a first subset of vehicles, a first electrical characterization, the first subset of vehicles including vehicles of a first vehicle make, model, and fuel type;
- determining, by the at least one processor for a second subset of vehicles different from the first subset of vehicles, a second electrical characterization, the second subset of vehicles including vehicles different from the first subset of vehicles in at least one of vehicle make, model, or fuel type;
- determining, by the at least one processor, a difference between the first electrical characterization and the second electrical characterization;
- selecting, by the at least one processor, a select subset of vehicles, wherein:
- the select subset of vehicles includes the first subset of vehicles;
- the select subset of vehicles includes the second subset of vehicles if the difference between the first electrical characterization and the second electrical characterization is within a characterization threshold;
- and
- the select subset of vehicles does not include the second subset of vehicles if the difference between the first electrical characterization and the second electrical characterization is not within the characterization threshold;
- and
- generating, by the at least one processor based on electrical data representing vehicles of the select subset of vehicles, an electrical system metric which is indicative of electrical system performance of vehicles which correspond to vehicles in the select subset of vehicles.
