Assignee: nan
Field: Measurement (Instruments)
Classification: CPC H  G | IPC G  H

Claim 16:
17. A jump starter device with a diagnostic function as in claim 12,
wherein the diagnostic circuit comprises a circuit configured to provide one or more measurements of a current,
wherein the controller is configured to process the one or more voltages and the one or more measurements of the current to or from the battery to determine the condition of the vehicle,
wherein the condition of the vehicle comprises at least one of
a state of charge of the battery determined from the one or more voltage values during a period of the vehicle not running,
an internal resistance of the battery determined from the diagnostic circuit,
a cold cranking amps value of the battery determined from the internal resistance,
a battery life determined from the cold cranking amps value,
a capacity of the battery determined from the one or more voltage values during a period of the vehicle starting,
a charging rate of the battery determined from the one or more voltage values during a period of the vehicle running,
a state of charge of the battery determined from the one or more voltage values during a period of the vehicle running,
a capability of the alternator to generate a charge current determined from the one or more voltage values during a period of the vehicle running, or
an assessment of a rectifying diode in the alternator determined from the one or more voltage values during a period of the vehicle running.
