20120029852 | BATTERY MONITOR SYSTEM ATTACHED TO A VEHICLE WIRING HARNESS - A computer system that installs in the proximity of the vehicle's operator by attaching to the vehicle's wiring harness (e.g., via a power outlet in the vehicle cabin). The device, gathers data relating to the operational state of the vehicle's battery, calculates various health information of the battery from the gathered data, and provides the health and operational state of the battery to the vehicle's operator. To facilitate battery health calculations, the device receives input from a temperature sensor that is remote to the battery, such as a temperature sensor in the device's housing or in the vehicle cabin. The temperature reading can be used to approximate the temperature of the battery. The computer system can also support non-battery related functions, such as navigation, theft deterrence, etc. Algorithms utilizing battery health data over multiple load cycles to determine the health of a battery are also disclosed. | 02-02-2012 |
