Abstract
Provided is a battery management system. The battery management system includes: a battery management system (BMS) monitoring a battery, turning on/off a main relay connected to an output of the battery, and receiving power through a power switch; a sensor unit measuring a state of the battery to generate battery state information; and a controller configured to receive the battery state information from the sensor unit, detect an occurrence of a failure event of the battery based on the battery state information, control the main relay based on a maintenance time of the failure event and the number of times of the occurrence of the failure event, and provide a turn on/off command to the power switch.
Claims15
A battery management system comprising:
- a battery management system (BMS) monitoring a battery, turning on/off a main relay connected to an output of the battery, and receiving power through a power switch;
- a sensor unit measuring a state of the battery to generate battery state information;
- and
- a controller configured to:
- receive the battery state information from the sensor unit, detect an occurrence of a failure event of the battery based on the battery state information, control the main relay based on whether a maintenance time of the failure event being longer than a reference time T1d and whether the number of times of the occurrence of the failure event being greater than a reference set value Sth, and provide a turn on/off command to the power switch,
- wherein the controller accumulatively increases a stress index of the battery when the failure event occurs, and turns off the main relay when a duration of the failure event is equal to or shorter than T1d and the stress index of the battery is greater than Sth.
A method of managing a battery using a battery management system (BMS) monitoring the battery, turning on/off a main relay connected to an output of the battery, and receiving power through a power switch, comprising:
- measuring battery state information;
- detecting an occurrence of a failure event of the battery based on the battery state information;
- controlling the main relay based on whether a maintenance time of the failure event being longer than a reference time T1d and whether the number of times of the occurrence of the failure event being greater than a reference set value Sth;
- and
- turning on/off the power switch;
- and
- accumulatively increasing a stress index of the battery when the failure event occurs, and turning off the main relay when a duration of the failure event is equal to or shorter than T1d and the stress index of the battery is greater than Sth.
