摘要： A vehicle battery system and a method of controlling charge of a battery in the system are provided. The system includes a first battery module that has a plurality of battery cells connected to each other in series and a second battery module that has a plurality of battery cells connected to each other in series. The second battery module is connected to the first battery module in series. A controller then monitors a state of charge of each of the first and second battery modules, such that when the state of charge of one of the first and second battery modules is less than a predetermined level, the controller performs active cell balancing between the battery cells of the first battery module and the battery cells of the second battery module.

摘要： A drive control method based on detected dielectric breakdown is provided. The drive control method includes individually determining whether dielectric breakdown of high voltage components occurs according to whether a switch for electrically connecting a high voltage battery and other high voltage components is opened and a condition of each of the high voltage components when dielectric resistance of a vehicle is measured to determine that dielectric breakdown of a high voltage system occurs. An operation of the high voltage components, the dielectric breakdown of which occurs, is stopped according to a determination result, when dielectric breakdown of high voltage components, which do not affect vehicle driving among the high voltage components, occurs.

摘要： A system for charging a vehicle battery includes a relay configured to establish/interrupt electrical connection between the vehicle battery and a vehicle system supplied with power from the vehicle battery, and a controller. The controller is configured to monitor a voltage of the battery, control the relay to interrupt the electrical connection when a voltage of the battery is less than or equal to a first predetermined reference value, and control the relay to establish the electrical connection when a predetermined condition is satisfied while the relay is electrically disconnected. The controller controls the relay to be electrically connected to charge the battery through an external power source while the electrical connection is interrupted, and then control a connection state of the relay based on the voltage of the battery, a voltage and current of the relay at a side of the vehicle system, and whether a vehicle is started.

摘要： A battery management system for a vehicle is provided. The system is capable of preventing vehicle malfunction by preventing overcharge and over-discharge of a low-voltage battery by providing a controller that is configured to receive power transmitted from a first connection line and power transmitted from a second connection line. The battery management system includes a relay configured to electrically connect and disconnect power that is supplied from a battery to loads. The system also includes a controller configured to receive a first regular power transmitted through a connection line between the battery and the relay and a second regular power transmitted through a connection line between the relay and the loads. The controller is further configured to turn the relay on and off.

摘要： A battery management system of a vehicle is provided to prevent a lithium battery from being overcharged and over-discharged and to safely protect the lithium battery from various conditions degrading the lithium battery when the lithium battery is used as a low-voltage battery in the vehicle. The battery management system includes a relay that electrically connect and disconnects power supplied to a load from a battery and a reconnection switch that determines a connection state based on user manipulation and generates a signal for turning the relay on and off based on the connection state. Additionally, a controller turns the relay on and off based on the connection state of the reconnection switch.

摘要： The battery jump-starting method includes determining whether a vehicle is available for jump-start, turning off a switch controlling a relay when the vehicle is available for jump-start, and temporarily driving the vehicle in a state in which the switch is maintained in an OFF state when the vehicle is started. The battery jump-starting method enables a vehicle to temporarily drive when starting in a situation in which it is not possible to replace or charge a battery, upon determining whether the vehicle is available for jump-start.
