1. A battery control method of a recharging/discharging controller comprising:
- receiving a reprogramming request from a diagnostic device located outside of a vehicle to reprogram software of one or more electronic control units (ECUs) of the vehicle;
determining a number of the ECUs to be reprogrammed and whether or not a state of charge (SOC) of an auxiliary battery exceeds a critical value varied depending on the number of the ECUs to be reprogrammed;
based on the determining step, performing reprogramming of the one or more ECUs or recharging of the auxiliary battery; and
sending a signal informing of the reprogramming or a warning signal associated with the recharging to the diagnostic device.

Abstract
A battery control method includes: receiving a reprogramming request from a diagnostic device located outside of a vehicle to reprogram software of one or more electronic control units (ECUs) of the vehicle; performing reprogramming of the one or more ECUs or recharging of an auxiliary battery according to a number of the ECUs to be reprogrammed and whether or not a state of charge (SOC) of the auxiliary battery exceeds a critical value varied depending on the number of the ECUs to be reprogrammed; and sending a signal informing of the reprogramming or a warning signal associated with the recharging to the diagnostic device.

11. A recharging/discharging controller comprising:
-
a communication unit receiving a reprogramming request from a diagnostic device located outside of a vehicle to reprogram software of one or more electronic control units (ECUs); and a control unit determining a number of the ECUs to be reprogrammed and whether or not a state of charge (SOC) of an auxiliary, battery exceeds a critical value varied depending on the number of the ECUs to be reprogrammed, and based on the determination, performing reprogramming of the one or more ECUs or recharging of the auxiliary battery, wherein the communication unit sends a signal informing of the reprogramming or a warning signal associated with the recharging to the diagnostic device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A non-transitory computer readable medium containing program instructions for performing a battery control method, the computer readable medium comprising:
-
program instructions that receive a reprogramming request from a diagnostic device located outside of a vehicle to reprogram software of one or more electronic control units (ECUs) of the vehicle; program instructions that determine a number of the ECUs to be reprogrammed and whether or not a state of charge (SOC) of an auxiliary battery exceeds a critical value varied depending on the number of the ECUs to be reprogrammed; program instructions that perform reprogramming of the one or more ECUs or recharging of the auxiliary battery according to the determination; and program instructions that send a signal informing of the reprogramming or a warning signal associated with the recharging to the diagnostic device.
