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.

Abstract: Vehicles can employ onboard telematic monitoring devices to collect vehicle and operation data, such as for improved vehicle fleet management. Such telematic monitoring devices are dependent on power from a vehicle, such that data collection and communication can be interrupted if a telematic monitoring device is disconnected or has a poor connection. The present disclosure relates to battery devices, which provide power to telematic monitoring devices as needed in order to maintain data collection and communication, or other more limited functionality. The present disclosure also relates to systems including battery devices, and methods for operating battery devices. The present disclosure also relates to detecting temperature of batteries, as well as emergency input and messages for telematic monitoring systems.

Abstract: A method for handling input/output (I/O) expansion power faults in a telematics device is provided. The method includes setting an I/O expander power-off duration to an initial value and powering on an I/O expander interface. In response to detecting a power fault at the I/O expander interface, the I/O expander interface is powered-off dur the power-off duration and the power-off duration is increased. If the power-off duration is greater than the power-off duration limit, the I/O expander interface is permanently powered-off. The steps are repeated until either the power fault does not recur, or the I/O expander interface is permanently powered-off.

Abstract: A method and a system for impact detection in a stationary vehicle are provided. The method includes putting a telematics device into a sleep mode, performing at least one micro wakeup, determining at least one value from at least one sensor during the micro wakeup. The method also includes storing the at least one value, returning to sleep mode, and waking up from the sleep mode. The method further includes sending the at least one value over a network interface to a telematics server. The telematics device which carries out the method has a controller, memory, and network interface. An accident impact profile may be recorded during the micro wakeups and sent during a wakeup duration for analysis by the telematics server.

Abstract: The present disclosure relates to systems, devices, and methods for analyzing health of vehicle batteries. Vehicle batteries tend to degrade over time. The described systems, devices, and methods quantify this degradation (or quantify remaining health of the battery) by comparing average energy used to charge or discharge the battery by a charge level unit to a nominal quantity of energy used to charge or discharge a battery in optimal health by a charge level unit. Charge data for previous charge events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified charge events based on at least one of a number of metrics. Usage data for previous usage events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified usage events or subgroups of usage event based on at least one of a number of metrics.

The method includes performing a plurality of micro wakeups to capture voltage values during a cranking event, determining the maximum cranking voltage and its timestamp, detecting an ignition signal, determining the maximum device voltage and its timestamp, and determining a potential alternator undercharging condition if a duration between the maximum cranking voltage timestamp and the maximum device voltage timestamp is greater than an undercharging indicator duration threshold. Advantageously, an alternator may be repaired or replaced before it fails thus averting having the motor vehicles inoperable.

An example method includes receiving data messages from an asset coupled to the asset tracking system and attempting to obtain asset information from data messages with reference to a local set of signal definitions indicating how data messages received from the asset are to be decoded into asset information.

The asset tracking system provides access to at least one undecoded data message of the outstanding data type to the asset data analysis system, receives the generated signal definition from the asset data analysis system, and adds the generated signal definition to the local set of signal definitions.
