Abstract
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.
Claims11
A battery management system of a vehicle, comprising:
- a relay configured to electrically connect and disconnect power supplied to a load from a battery;
- a reconnection switch configured to determine a connection state based on user manipulation and generate a signal for turning the relay on and off based on the connection state;
- and
- a controller configured to turn the relay on and off based on the connection state of the reconnection switch.
A battery management system of a vehicle, comprising:
- a relay configured to electrically connect and disconnect power supplied to a load from a battery;
- and
- a controller connected directly to the battery and configured to receive standby power, set a time period for being woken up, and output a control signal for turning off the relay when a voltage of the battery is equal to or less than a preset threshold value,
- wherein the controller is configured to change the time period after the relay is turned off.
