Abstract
A battery pack diagnostic apparatus includes a communication port, a measurer, and a controller. The communication port provides an electrical connection between the battery pack diagnostic apparatus and a battery management system. The measurer is electrically connected to an output terminal of the battery pack and is configured to measure a voltage and a current of the battery pack. The controller is configured to obtain a first measurement value with respect to a voltage and a current of the battery pack from the battery management system. The controller is further configured to obtain a second measurement value with respect to a second voltage and a second current of the battery pack from the measurer. The controller analyzes a state of the battery pack based on the first measurement value and the second measurement value.
