Abstract: Systems, methods, devices, and models for range estimation and analysis in battery powered vehicles are described. Energy consumption over vehicle trips is collected, to evaluate weighting factors for a weighted sum. The weighted sum is evaluated based on determined weighting factors and expected trip data, to determine an energy consumption of a trip or trips of a vehicle. Determined energy consumption for trips is used for evaluating suitability of the vehicle for performing the trips.

The electric harness includes a main branch with a current limiter, and a secondary branch with an electric energy storage device. When the secondary electronic device makes an inrush current demand, the electric energy storage device supplies an auxiliary electric current in the auxiliary branch which when added to a main current in the main branch, meets the inrush current demands.

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.

Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.

Abstract: Systems and methods for processing geographical zones are provided. The method involves operating at least one processor to: define a bounding box surrounding a geographical zone; iteratively partition the bounding box into a plurality of bounding boxes by, starting with the bounding box in the first iteration: determine whether the bounding box contains more than a predetermined maximum number of vertices; divide the bounding box into two additional bounding boxes if the bounding box contains more than the predetermined maximum number of vertices, repeat the steps of determining and dividing the bounding box for the additional bounding boxes in the next iteration until each additional bounding box does not contain more than the predetermined maximum number of vertices; generate a binary tree data structure representing the geographical zone; search the binary tree data structure to determine whether a vehicle is located within one of the bounding boxes.

Abstract: Methods and systems for simplifying data collected from assets are provided. An example method involves receiving a simplified set of data at a server. The simplified set of data is generated by application of a dataset simplification algorithm on raw data obtained from a data source at an asset upon a determination that a recently obtained point in the raw data differed from a corresponding predicted point predicted by extrapolation based on previously saved points included in one or more previously generated simplified sets of data by an amount of extrapolation error that is limited by an upper bound that is fixed as the raw data is collected over time. The method further involves receiving a request for a status of the asset and extrapolating a status of the asset based on the simplified set of data in response to the request.

Abstract: Systems and method for safe over-the-air (OTA) update of electronic control units in vehicles are provided. The OTA server determines whether an operator terminal is close to a vehicle and if so, sends a request to the operator terminal requesting confirmation for proceeding with completing a firmware update for an electronic control unit in the vehicle. In response to receiving the confirmation, the OTA server sends a request to a telematics device coupled to the vehicle to complete the firmware update.

Abstract: Described herein are methods of processing telematics data that include receiving initial telematics data related to a vehicle from a telematics device and processing the initial telematics data to generate processed telematics data.

For each recipient of a plurality of recipients, the methods additionally include distributing the determined data to the recipient.

Abstract: Systems, methods, models, and training data for models are discussed, for determining vehicle positioning, and in particular identifying tailgating. Simulated training images showing vehicles following other vehicles, under various conditions, are generated using a virtual environment. Models are trained to determine following distance between two vehicles. Trained models are used in detection of tailgating, based on determined distance between two vehicles. Results of tailgating are output to warn a driver, or to provide a report on driver behavior. Following distance over time is determined, and simplified following distance data is generated for use at a management device.

Abstract: The present systems, devices, and methods relate to managing vehicle battery charging. Payment for charging is preauthorized, and a receipt for preauthorization is sent from a payment management device to a user device when the user device has access to internet or cellular communications. This preauthorization receipt is later sent from the user device to a charge station where internet or cellular communication is not available, to enable charging of the vehicle battery at the charge station. Another receipt is sent from the charge station to the user device after charging of the vehicle, indicating a payment amount for actual energy used to charge the battery. Later, when the user device has access to cellular or internet communications, the user device sends the receipt indicating payment amount for actual energy used to the payment management device, for final payment balancing.
