Abstract
A battery protection apparatus including a first current sensor connected to a positive terminal of a battery to measure a first current value; a second current sensor connected to a negative terminal of the battery to measure a second current value; a contactor including a first contactor positioned between the positive terminal of the battery and the first current sensor and a second contactor positioned between the negative terminal of the battery and the second current sensor; and a controller for setting a representative current value among the first current value and the second current value, and determining whether the representative current value is an abnormal current, and thus, it is possible to measure battery current stably even when one current sensor fails by measuring and monitoring current using heterogeneous current sensors, and protecting the battery from abnormal current based on the representative current value of the battery.
