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.
