Abstract: Vehicle diagnostic tests may be performed by an owner of a vehicle on a self-serve basis. In one implementation, a method may include communicating, by a vehicle diagnostic device, with a vehicle through an OBD connector of the vehicle, to obtain diagnostic information relating to operation of the vehicle. The method may further include receiving instructions relating to the obtaining of the diagnostic information and playing, via a speaker associated with the vehicle diagnostic device, the instructions as audible instructions.

Abstract: Adapters for OBD ports of a vehicle may include mechanisms for identifying the adapter (e.g., determine the manufacturer and/or type of the adapter) to an OBD device that is being used with the adapter. In one implementation, a male OBD connector of an OBD device may include a set of upper pins, a set of lower pins, and a middle portion, disposed between the set of upper pins and the set of lower pins, the middle portion including one or more pins. Identification logic, of the OBD device, may include a sensor connected to the one or more pins, to sense one or more values corresponding to a type of the compatible adapter.

Abstract: A battery-powered vehicle telematics device includes solar cells for powering the device and charging the battery. A Bluetooth® link connects the telematics device to a dongle that has been coupled to a diagnostic port of the vehicle. A USB computer connection may also provide power to the telematics device to assist the solar cells in charging the battery. The dongle and telematics devices include accelerometer components that can detect a start event and signal that the telematics device should begin operating. The accelerometers can also be used to calculate a roll angle. The telematics device can transmit a roll angle value to an active handling system or to a central server along with other vehicle information received from the dongle for further analysis and processing. A processor in the telematics device can automatically adjust and optimize the solar cell angle to maximize the capture of incident radiation.

Abstract: A telematics device or a mobile wireless device, or a computer server remote from a vehicle, receives data related to the vehicle battery's open circuit and cranking voltages, temperature, and usage. The device compares the received data to predetermined corresponding criteria and also computes a battery health value based on the received data according to an algorithm. If the received data falls outside the corresponding criteria, the device can generate and send an alert to a user device. The battery health value can be sent to the user device to indicate remaining battery life, and to correlate temperature and vehicle usage with impact on battery life. The received data can also be used to generate a customized charging current profile that a charging device can use to regulate charging current from the vehicle's alternator to the battery. The vehicle can use an internal combustion engine, or be all-electric.
