Abstract
A lift device includes multiple electrical components and a battery monitoring system. The battery monitoring system includes multiple batteries and a controller. The multiple batteries are configured to power the multiple electrical components. The controller is configured to obtain sensor data from the batteries. The controller is also configured to determine a state of charge of the batteries for open circuit conditions based on the sensor data. The controller is configured to determine a state of charge of the batteries for load conditions based on the sensor data. The controller is configured to determine a state of charge of the batteries for charging conditions based on the sensor data. The controller determines an overall state of charge of the batteries based on the state of charge for open circuit conditions, the state of charge of the batteries for load conditions, and the state of charge for charging conditions.
