Embodiment Construction

[0035] introduce

[0036] A vehicle includes a battery health assessment system. Upon determining that the ambient temperature equals or exceeds the first temperature, the vehicle battery is electrically charged. The voltage of the battery is measured during loading. The magnitude of the voltage plateau is determined. Once the magnitude of the plateau is determined to be less than the target voltage, the battery is identified as unsuitable.

[0037] Relative orientations and directions set forth in this specification (by way of example, above, below, bottom, forward, backward, front, rear, rear, outside, inside, inward, outward, lateral, left, right ) not as a limitation, but to facilitate the reader's ability to imagine at least one embodiment of the described structure. Such an exemplary orientation is from the perspective of an occupant seated in the driver's seat facing the dashboard. In the drawings, like reference numerals denote like parts throughout.

Once the magnitude of the plateau is determined to be less than the target voltage, the battery is identified as unsuitable.

Description

technical field [0001] The invention relates to a battery health evaluation method and system. Background technique [0002] Motor vehicles, including autonomous motor vehicles, may have internal combustion engines that are started by electric motors powered by batteries. When the battery is nearing the end of its life, it may not be able to hold enough energy to start the engine. Sometimes even the operator may not recognize the symptoms of a weakened battery. Autonomous vehicles may not be able to make such a diagnosis, or may lack an adequate human-machine interface for a human to make such a diagnosis. Contents of the invention [0003] According to the present invention, there is provided a computing device programmed to: [0004] electrically charging a vehicle battery of the vehicle upon determining that the ambient temperature equals or exceeds the first temperature; [0005] Measure the voltage of the battery during loading; [0006] determining the magnitude...
