Abstract: A method for protecting batteries with consideration for the influence of a load coupled to a battery pack is provided. The battery pack includes a terminal to be coupled to a capacitor of the load, and a battery management system for controlling a protection operation according to a voltage of the terminal, counting a number of protection operation executions after the load is coupled to the battery pack, and differently controlling a deactivation time of the protection operations depending on whether or not the number of executions is greater than or equal to a reference count.

Abstract: A battery charging apparatus and charging method thereof are disclosed. In one aspect, the apparatus includes a battery including a battery pack including at least one battery cell, a battery management system (BMS) configured to control the generation of a terminal voltage based on a type of the battery pack, and a terminal unit including electrodes configured to receive the terminal voltage. The apparatus further includes a charger including a controller configured to determine the type of the battery pack based on the terminal voltage and control the generation of a charging voltage corresponding to the type of the battery pack.

Abstract: There is provided a method and apparatus for controlling charging of a secondary battery. The apparatus includes a receiving unit, a sensing unit and a charging controller. The receiving unit receives a full-charge time of the secondary battery from a user terminal. The sensing unit monitors a charging state of the secondary battery. The charging controller controls charging of the secondary battery, using the full-charge time and the charging state. Accordingly, the charging of a secondary battery is controlled to be completed at a full-charge time desired by a user, thereby preventing deterioration of the secondary battery.

Abstract: A battery charging device includes: a charging unit coupled to a battery module, the battery module including at least one battery cell, wherein the charging unit is configured to charge the battery module; and a charge controller configured to: receive, from a battery management system managing to battery module, measurement information indicating whether or not an open circuit voltage (OCV) value of the battery module is within a predetermined voltage section; and transmit a discharge start signal to the battery management system to discharge the battery module in response to a value of the measurement information exceeding a predetermined number.

Abstract: An apparatus includes a controller to output a signal through an interface. The signal may control at least one parameter of a motor based on a state of capacity degradation of a battery for driving the motor. The at least one parameter may be motor torque. Also, the signal may include a value indicative of a capacity degradation of a battery for driving a motor. The capacity degradation of the battery may be determined based on a number of charging and/or discharging operations performed for the battery.

Abstract: A password setting device includes a selection button and a plurality of light-emitting elements. The selection button determines a state of charge of a battery pack and is also used to enter various types of information including symbols of a password. The light-emitting elements to emit light depending on the state of charge of the battery pack in a first mode. At least some of the light-emitting elements correspond to symbols of a password in at least a second mode. The password is to be set or input based on the light-emitting elements that emit light at a time when the selection button is activated in at least the second mode.
