A battery pack diagnosing device mediating signal communication between a battery pack and a user terminal includes a controller generating a wake-up signal based on a user input to a third switch and transmitting the generated wake-up signal to the battery pack, and establishing a communication connection according to a first communication method with the battery pack turned on based on the wake-up signal and receiving state information of the battery pack through the established communication connection.

Device and method for diagnosing battery pack

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.

A battery pack management system and method that can increase the stability of a product employing the battery pack by directly or indirectly correcting an error when the error is generated in a microprocessor of the battery pack. In the battery pack management system, the host device receives updated data of a predetermined program from the server through communication with the server and transmits the received updated data to the battery pack. The battery pack includes a battery cell, a charge/discharge control unit that controls charging and discharging of the battery cell, a microprocessor that incorporates a storage medium that records and stores the updated to data of the predetermined program transmitted from the host device, the microprocessor controls the charge/discharge control unit to be reset and applies the updated data of the predetermined program to the charge/discharge control unit to operate the charge/discharge control unit in a safety mode.
